Living Off Grid

Off-grid living is becoming an increasingly popular choice for people looking to reduce their carbon footprint, assert their independence and avoid reliance on fossil fuels. In the past, lead-acid batteries have been a complication in off-grid systems, forcing people to discharge only a fraction of their total amperage, creating battery anxiety with nearly constant maintenance. This has led to heavy and bulky battery banks that are still unable to provide power for long periods of time. Battle Born Batteries can eliminate this problem altogether, as well as many other associated issues.

Our batteries are designed to weigh less, perform better and last longer, making them perfect for off-grid living. We offer 12  and 24 volt batteries that can be wired as 12, 24, 36 and 48 volt systems, tailoring your battery bank to fit your needs. Our team of experts have designed many lithium off-grid solar power systems with users ranging from the professional installer to the do-it-yourself layman. If you would like to discuss the right set up for your application, please contact us and we will assist you with any questions or concerns you may have.

Inverter Charger

A standard inverter is an electrical device that turns direct current (DC) power into alternating current (AC). A battery charger (converter) takes standard 120 V AC power and converts it to DC power to charge your batteries.

An inverter charger, much like the name states, is a combination of an inverter and a battery charger. It can take the AC power from a generator or shore power and charge your DC battery bank. It will also turn your battery’s DC power into AC power for any household appliances or electronics.

The Battle Born Shop carries multiple inverter/chargers for various power requirements from brands such as Victron and Magnum.  

*One should note that additional components may need to be purchased alongside an inverter charger to best fit the needs of a system

Solar Panels

Implementing a solar system can be confusing to say the least. Solar panels come in a wide array of shapes, sizes, wattage, voltages and types. Should you go with Monocrystalline (MPPT), Polycristalline (PWM), thin film, or amorphous? Do you need 12 V panels, 24, 48, or maybe even 72 volts?

The good news is, by following a few basic rules, you can figure out how many watts you need for properly charging your Battle Born Batteries. 

How many watts?

As a basic rule, match 200-250 watts of any solar type, for each 100 Ah of your lithium battery bank. This should allow charging from nearly empty to full in one full day of direct sunlight. Just make sure that your solar charge controller is compatible for charging lithium.

What voltage of panel?

Select your solar charge controller, then choose the voltage of your solar panels. MPPT solar charge controllers handle voltages of 75 V up to 250 V, depending on the model, meaning you can easily build a solar array with almost all voltage types. The less efficient PWM solar controllers usually only handle 12 or 24 volts, limiting your choices of solar panels.

Connect my solar array in series or parallel?

Again, this will depend on your solar charge controller. For most PWM controllers, parallel connections work best. Parallel connections keep voltage of your solar array low as these controllers can’t handle the higher volts. Series connecting is preferred with MPPT controllers as this can create more efficiency with the higher voltage that’s created connecting this way.

Parallel solar connections give a measure of shade tolerance, meaning if you cover one panel out of the array, the other panels still generate a good amount of power. Series solar connections give a bit more efficiency and power but tend to give much less power when one panel is shaded from the array. Many choose a hybrid of both series and parallel and will give the best of both worlds. 

These are generalities and many factors can change recommendations. If you would like to discuss your solar array and the components involved, don’t hesitate to give us a call at (855) 292-2831 or email us at [email protected]. 

Solar Charge Controller

A solar charge controller is a current or voltage controller that manages the power that transfers from your solar array to your battery bank. A solar charge controller takes the power that comes from the solar array to charge your battery bank and acts as a one-way gate to prevent this power from transferring back to the solar array, which would subsequently drain the batteries.

There are two main types of solar charge controllers: Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT). Check out what solar charge controllers we offer here.

Pulse Width Modulation (PWM)

Pulse width modulation solar charge controllers are relatively simple controllers that are connected directly between your solar array and your battery bank. It will “pull down” the voltage of your solar array to match that of your battery bank.

As your battery bank approaches its maximum capacity, the PWM solar charge controller will begin to reduce the amount of power feeding into your batteries. A PWM solar charge controller will also trickle charge your batteries to keep them topped off once the battery bank is full.

An important thing to consider with these solar charge controllers is that the voltage of your solar array and your battery bank need to match so this makes it more ideal for smaller systems.

Maximum Power Point Tracking (MPPT)

Maximum Power Point Tracking solar charge controllers are a more complex option that also harvests more energy from the solar array, which leads to higher efficiencies. An MPPT solar charge controller will also act like a PWM in the sense that it will reduce the power flowing to your battery bank as it reaches maximum capacity.

Unlike a PWM, an MPPT controller can be used with a solar array and battery bank of different voltages. It will down convert the voltage of your solar array to match the battery voltage and will subsequently increase the current so more available solar power can be harvested. MPPT solar charge controllers are also 20-30% more efficient than PWM solar charge controllers, making them a great option for high power systems. 

We offer a variety of sizes for solar charge controllers depending on the size of your solar array. We also offer Victron Solar Charge Controllers that can be pre-programmed for your specific system.

You can determine which solar charge controller is best for your system through this compatibility chart. 

Battery Monitor

Battery monitors are great tools to help you keep track of your battery system. They can give you specific information, such as how much power you have left and total ampere-hours consumed. We carry three different types of battery monitors: the Victron BMV-712, the Victron BMV-702, and the Victron BMV-700. You can check these battery monitors out here.

The Victron BMV-700 and Victron BMV-702

The Victron BMV-700 and BMV-702 will calculate the remaining battery capacity based on your ampere-hours consumed, discharge current, and the age of your battery. The physical display can show voltage, current, ampere-hours consumed, the state of charge, time to go, and your power consumption in watts.

To install one of these monitors you just need to connect to the quick connect protection circuit board (PCB) on the current shunt. Some of the other features are that they offer include programmable audible and visible alarms, a programmable relay, and data storage which allows you to track battery usage and health.

The BMV-702 varies from the BMV-700 because it allows for an additional input to be able to measure the voltage of another battery, temperature, and midpoint voltage monitoring. Midpoint voltage monitoring gives you the voltage halfway along your string of batteries. This information can inform you if there is an issue with your battery system, which can prevent severe damage down the line. The BMV-702 also allows for alarm and relay settings for these additional features.

The Victron BMV-700 and-702 can become Bluetooth enabled by adding the Bluetooth Smart dongle to your system, which can be found here. This dongle simplifies the programming of your BMV and allows you to monitor your system on a smartphone, tablet, laptops, and other devices.

The Victron BMV-712

The Victron BMV-712 provides the same functionality as the BMV-702, but it also comes fully Bluetooth enabled. This will simplify the wireless communication between products and your overall  installation process. To install it you make all electrical connected to your quick connect PCB on the current shunt, like you would do with the BMV-700 and BMV-702.

Battery Charger

A battery charger takes alternating current (AC) from either shore power or a generator and converts it into direct current (DC) used to charge your batteries. These chargers come in a variety of options from single to multi-battery charging, along with a variety of different charge rates, which dictate how quickly your batteries reach a full charge. See our LiFePO4 battery chargers page for more details.


Battery Guardian

The battery guardian (BG) is a great component if you are looking for a low voltage disconnect.

Restricted for only 12 V power systems, this component allows you to remotely disconnect the vehicle from the battery by sensing the voltages of the coach or auxiliary batteries. We recommend using a BG when you intend to store your system for long periods of time.

When a BG is incorporated into your system, it works as a direct current (DC) disconnect switch, and it will cut off loads once your batteries reach 11.5 V. This will protect your batteries during long-term storage as it prevents the loads from draining your batteries and will completely eliminate the cumbersome task of physically removing the battery cable from the bank of batteries. Check out the product listing for the Battery Guardian.

For a basic connection diagram of the Battery Guardian please refer to the schematic below.

There are two types of connections that you can make to your ignition connection on your BG.

We recommend Option A which leaves the ignition terminal disconnected. As a response, the BG will disconnect the coach battery when it sees it reach a voltage of 11.5 V.

The second option, Option B, would be to connect the ignition terminal to the ignition switch of the vehicle. As a response, the BG will not disconnect when the ignition switch is on. When the ignition switch is off, the batteries will disconnect at a voltage of 12.2 V.

Wiring Options

There are three different wiring options when making the signal (sig) connection.

The first option, which we recommend, is referred to as the AUTO connection, where the signal terminal is connected directly to the ground. As a response, the BG will disconnect the batteries when the voltage goes below 11.5 V (or 12.2 V if using Option B for the ignition connection). In this setup, the BG will reconnect the batteries once their voltage is sensed to be above 13.3 V after 20 seconds.

The second option is referred to as the non-AUTO disconnect option. For this setup, the signal terminal is connected to a fuse (suggested 2 amps) and the toggle switch is connected to the positive terminal of the batteries. As a response, the toggle switch will act as a regular disconnect. When the toggle switch is closed, the batteries will not disconnect from the load. When the toggle switch is open, the batteries will be disconnected from the load.

The third option is an AUTO with a disconnect option. For this setup, the signal terminal is connected to the toggle switch, followed by a connection to the ground. In response to this, if the toggle switch is closed, the batteries will disconnect when the voltage goes below 11.5 V (or 12.2 V if using Option B for the ignition connection) for 2 minutes. The batteries will reconnect when the voltage is above 13.3 V after 20 seconds. If the toggle switch is open, the batteries will be disconnected from the load.

ANL fuses are designed to melt and separate into two pieces for the purpose of breaking a circuit in the event of excessive current.

These fuses are essential components protecting against a catastrophic event and are typically placed between Battle Born Batteries and the inverter.

Our ANL fuse kits include the base, cover, and the fuse itself. Check out our fuse kits and bundles with them here.

This is a heat pad that provides uniform heat and is sized for our BB10012, BB5024, or BBGC2 batteries.  You can purchase these heat pads here.


Adhesive allows the pad to sticks directly onto the case, wrapping around the battery. The heat pad runs off of 12 V, and can be off the battery itself, or another 12 V source like an engine alternator. It takes 30 watts of power when it is on, meaning it can run around 40 hours off of a full battery without a charging source.

Included with the heat pad is a temperature switch that turns the pad on when the temperature falls below 35 °F (1.6 °C), and stays on until the temperature rises above 45 °F (7 °C). This ensures that the heat pad is only on when needed.

*Disclaimer: All of our heat pads are tested with our Battle Born Batteries. Please do not use similar alternatives as they can cause the battery casing to deform.

The Color Control GX is the communication center of your installation. It offers live information at a glance and lets you control all products connected to it.

The Current Surge Limiter (CSL500) is a field-effect transistor (FET) based current limiting device. They are to be used with Battle Born Batteries LiFePO4 battery packs when they are used in conjunction with large (4 kw or larger) inverter chargers.

The device is mounted permanently in series between the negative pole of the battery bank and the negative direct current (DC) input terminal of the inverter charger. The device protects the battery management system (BMS) from damage caused by the initial current spike that is created when connecting directly to the large capacitors (> 5 milliFarads) that are typically on the DC input side of the inverter chargers.

The limiting device allows the batteries to slowly charge the capacitors (within 1 ms). This soft start avoids the high-current shutoff inherent to the BMS of the batteries. Check out the CSL500 here.

Battery switches or “master disconnect” switches are a common item in RV/Marine systems. These battery switches are used to cut all power from a battery bank and connected loads.

These devices are very versatile and can be used in any circuit when performing maintenance or an emergency shut down. Very often you will see placement of these switches between inverter(s) and a bank of batteries.

Below are some of the most common styles:

Single on/off

3 position – used to shut off or switch from one bank of batteries to a second

4 position – used to shut off, switch from one bank to a second, or combine the two

Last 10 Times Longer than Lead Acid

Even after 3000 – 5000 life cycles Battle Born Batteries retain 75 – 80% of their original capacity. For most users, it will take 10 to 15 years to reach this amount of life cycles.

2 to 3 times more power

Our batteries will supply you with two to three times the power in the same physical space of a lead acid battery.

Charge 5 Times Faster

With a high charge rate of half of your total bank and short absorption times, your batteries will charge in a fraction of the time of a lead acid. This faster charge rate allows you to use your generator less which means less fuel consumption, less noise, and less pollution.

High Discharging Capabilities

Our 100 Ah batteries provide a continuous 100 amps of power, surge of up to 200 amps for 30 seconds and even higher loads for a ½ second.

Efficient and High Performance

Our batteries have virtually no internal resistance and will not heat up or swell when charging or discharging. We also have a real power rating so whether you’re using 1 amp for 100 hours or 100 amps for one hour, you will receive the full amount of power your batteries are rated for. With a very flat discharge curve, power remains much more consistent with Battle Born Batteries even at a low state of charge.

Environmentally Safe and Non-Toxic

One lead acid battery can contaminate acres of municipal waste, but Battle Born Batteries are not toxic and are made with the safest lithium chemistry on the market. This allows you to place them anywhere in your rig whether it’s under a bed, a dinette, or even a small enclosed area without the fear of our batteries “off gassing” like lead acid.


Our batteries are ½ to ⅔ the weight of a standard lead acid battery with more deliverable power.

Maintenance Free

Battle Born Batteries have a built-in management system to help protect you and your investment in the batteries in any strenuous situations such as high/low temperatures, high/low voltages, current surges, and short circuits. They also can be placed in your system with zero maintenance, so you no longer have to worry about adding water to your batteries or cleaning corroded terminals. Our batteries also have a very slow self-discharge rate so they can be left in storage for over a year without requiring you to hook them up to a trickle charger.

Excellent Solar Systems

Battle Born Batteries allow you to take full advantage of solar by creating fast charging and fully sustainable power systems with a variety of applications.

To determine whether your devices are compatible with BB batteries, take a look at the manual for each component and look at the specifications. If the specs in the manual match up with the Charging voltage: 14.2-14.6 V and the Float voltage: 13.6 V or lower, they are compatible with our batteries.  

If you can adjust settings (such as a custom profile) on your devices to various charging and float voltages, then simply change the settings to match ours.  

You are also more than welcome to give us a call at (855) 292-2831 or contact us at [email protected]. 

Answering this question depends on the amount of space you have in your application and how fast you want your bank to charge.

As a general guideline, we recommend 200 to 250 watts of solar per 100 amp-hours of battery. This will give you the ability to charge from nearly empty to full in a six to eight-hour time frame.

Many factors can change this calculation and you are invited to call at (855) 292-2831 or email us at [email protected] if you would like to discuss in greater detail.  

There are many specific models with different voltage and amperage ratings.  Which one is right for your application?   

Victron’s standard “Blue Solar” model is a set and forget controller without readouts or internal Bluetooth.  If you would like a Bluetooth version with all viewable information via the “Victron Connect” application from your mobile device, then the “Smart Solar” version is your best choice.   

Decide how many watts of panels you want in your solar array and take a look at our compatibility table to determine the product that best fits your system, here.  

Upon request we will program your Victron solar charge controller for the number of Battle Born Batteries in your bank at no charge.   

Yes, in most cases solar charge controllers have compatible battery settings such as a LiFePO4, or even an AGM mode that works well. 

To determine whether your solar charge controllers are compatible with Battle Born Batteries, read through the manual under the charging voltage tables. If the specifications match up with charging voltage: 14.2-14.6 V and the float voltage: 13.6 V or lower, then it will work great with your Battle Born Batteries. 

When considering cable sizing there are a few factors to consider.

First, what is the size of the load you are powering with the battery bank?

Second, how far away from the battery is the load? You can do voltage drop calculations to see if you need to step up your cable size.  

Here is an easy reference chart: 
Wire Cable Guide
As a rule of thumb, you can use these numbers as a guideline.

-4 AWG wire approximate max rating is 157 amps DC
-1/0 AWT wire approximate max rating is 291 amps DC
-4/0 AWT wire approximate max rating is 456 amps DC

Battle Born Batteries will hold a charge for up to a year without the need of a trickle charger. We recommend bringing the battery bank to a full state of charge then disconnecting all power coming or going to your battery bank.  

If you prefer to leave your batteries connected to a charger when in storage and the charging device has a float voltage of 13.8 V or lower, it is acceptable for use in long-term storage applications and will not harm our batteries.  

Selecting an inverter can be confusing due to the differing variations, styles and qualities available in stores and on the internet.

What is an inverter?

One of the primary functions of an inverter is to take direct current (DC) power and invert it into 120 volts, for using appliances. This can be through a wall receptacle or directly from the inverter.

Many all-in-one units allow a pass-through from shore power or genset, a high amperage DC charger and transfer switch.

What else should I know?

We recommend inverters that have a “pure” or “true” sine wave as the “modified” or “square” wave inverters are harder on components, cause more heat and can lead to damage to sensitive electronics over longer periods of time. Victron, Magnum and Xantrex, are some examples of high quality units that are used in many off grid applications.

One of the most important things to consider is your maximum need in wattage at any given time. Take a look at the wattage specifications on your devices and consider which of these you will be using at the same time and add them together.

For example, If your power need is 1600 watts then round up to a 2000 watt inverter. When choosing an multi-function inverter, consider how much of a maximum charge you will require for your bank of batteries.

Upon request we will program your Victron inverter charger for the number of Battle Born Batteries in your bank at no charge.  

Many inverter manufacturers recommend that you have some space around inverter sides and the top or bottom for air flow. This will allow the internal fans to circulate air within a compartment and properly cool your inverter when necessary. 

Please check your specific manufacturers recommendations and user manuals for further details.

Shunt based battery monitors are great tools to help you keep track of your battery system. Victron BMV series battery monitors give you specific information, such as how much power is coming into or going out of your battery bank at any given time from your devices.

They will also display how much time you  have left at your current rate of use, total amp hours consumed, a live feed on a graph representing voltage and current as well as historical data from previous days. Some of the other features include programmable audible and visible alarms and a programmable relay.

One of the best things about the BMV monitors is that the information is easily viewed and configured from the “Victron Connect” app for any mobile device. In addition to this Bluetooth connectivity, each BMV comes with a highly visible, back-lit display that can be mounted anywhere within your system.

The option we sell on our website is the Victron BMV-712. You can find that listing here.

Sizing a battery bank for an off-grid or mobile power system can get complicated if you don’t have all the information you need to make the right calculations. You will need some basic information to get started.  

You will need the maximum and continuous draw – in amps or watts – of the devices you want to power. These are usually found somewhere on the device on a sticker or plate that shows the amps and volts of that device or the power in watts. 

As an example, let’s just say that our system needs to run 10 amps at 120 volts for 3.5 hours.  

10 amps x 120 volts = 1200 watts of power.  

1200 watts x 3.5 hours = 4200 watt-hours of energy.  

Next you need to convert 4200 watts-hours to direct current (DC) amp-hours. For our example, we will use a 12 volt battery bank.  

4200 watts-hours / 12 volts = 350 DC amp-hours of battery energy needed for our sample application.  

Also, the battery needs to be able to deliver 1200 watts/ 12 volts = 100 amps of power.  

We will use the 100 amp-hour Battle Born battery to build this system.  

350 amp-hours / 100 amp-hours = 3.5  

We would need to use four 100 amp-hour LiFePO4 Battle Born Batteries to power this system. 

Yes, you can mount your battery in any position. There is no acid inside of the battery, and the small amount of liquid electrolyte is contained within each sealed cell.

You can decide what is best for your application. Our lithium technology gives you the flexibility to put the battery in places you normally would not have placed a lead acid battery. 

Battle Born Batteries protect themselves from charging in cold temperatures and won’t accept a charge once the internal cell temperature drops to 24°F. At this point they will continue to discharge even down to -4°F. At this temperature we recommend no longer pulling power to avoid damaging the batteries.

Insulated battery boxes, heating blankets, and placing your battery bank inside your RV will help keep the temperature stable. On the high end of temperature range, the batteries will shut down once 135°F is reached.

We recommend not to exceed a charge rate of 50 amps for each 100 Ah battery. For more than one battery, you can simply take the entire Ah of the bank and cut the number in half.

For example, three 100 Ah Battle Born Batteries total 300 Ah. Cut this number in half and you have your maximum recommended charge rate of 150 amps. 

The length of time it takes to charge a li-ion deep cycle battery depends on the type and size of your charging source.

Our recommended charge rate is 50 amps per 100 Ah battery in your system. For example, if your charger is 20 amps and you need to charge an empty battery, it will take about 5 hours to reach 100%.

We don’t recommend you exceed this charge rate as it can lead to a shortened battery cycle life. In an emergency situation the battery can be charged at a quicker rate if needed. 

Our charging parameters consist of the following: 

  • Bulk/absorb = 14.2 – 14.6 V
  • Float = 13.6 V or lower 
  • No equalization (or set it to 14.4 V) 
  • No temperature compensation 
  • Absorption time is 20-30 minutes per battery (if it’s an option

12 V 

Bulk/absorb 14.2 – 14.6 Volts (we usually recommend 14.4) float 13.6 Volts or lower 

No equalization (or set it to 14.4 V), no temperature compensation and absorption time is 20-30 minutes per battery (if it’s an option). 

24 V 

Bulk/absorb 28.4 – 29.2 V (we usually recommend 28.8 V) float 27.2 V or lower 

No equalization (or set it to 28.8 V), no temperature compensation and absorption time is 20-30 minutes per battery (if it’s an option).

Our Battery Monitoring System, or BMS is rated to 3 different levels.

  1. 100 amps continuous (1200 watts at 12 volts) – this means you can pull 100 amps out of the battery when you need it until the capacity is all used up.
  2. 200 amps for 30 seconds (2400 watts at 12 volts) – if your device has a surge an individual battery can deliver 2400 watts for 30 seconds.
  3. ½ second surge up to the max capacity of the battery. If you have a high momentary over 200 amps the battery will handle this for ½ second.

*Keep in mind that when you have two batteries in parallel you will double these surge numbers. With four batteries in parallel you will quadruple these figures.

If your battery registers between 0 to 5 volts this means that its in low voltage disconnect mode. This happens if the battery has been drained of capacity and is protecting itself from further discharge.

At this point you will need to apply a direct 12 V source such as the alternator via the starter battery or by connecting it to your starter battery with jumper cables until you see the voltage reaches 10-10.5 V.

Some inverter chargers will also bring the batteries out of low voltage disconnect. 

The best way to store our batteries for an extended period is to fully charge them and then disconnect them from everything. Removing the negative lead from the battery bank is also recommended. 

The batteries do not need a trickle charge or maintenance while stored. They will only lose around 2 – 3% of their charge per month. If possible, we recommend storing them in a temperature above freezing.  

Storing batteries in subzero weather (-15°F or lower) has the potential to crack the ABS plastic and could lead to a greater loss in charge. In some cases they can lose much more than the expected 3% monthly loss.  

If you are storing your entire system, we recommend the use of a  battery guardian, which will help protect your batteries by disconnecting them from parasitic loads once they reach a voltage of 11.5 V. 

You can use all of the power out of your Battle Born battery without damage, but it should not be left in this condition for long.

The BMS will shut the battery off to protect the cells once it reaches a low voltage between 10-10.5 volts. This is referred to as low-voltage disconnect, and the battery can be brought out of this protection mode by being connected to any 12 volt source.

Any battery that is fully discharged should not be left in this state for long periods and should be charged soon after in order to avoid long-term damage

Our batteries are sealed and do not “off gas” or cause any toxic fumes, so there is no need for a ventilated storage compartments. This can allow the batteries to be placed inside an off-grid structure, allowing for better protection from theft and exposure to the elements. 

Battle Born Batteries are 1/5th the weight of a traditional lead acid battery when matching the same usable capacity. This can result in a significant reduction in gross vehicle weight, not to mention being easier to load, install or move if necessary.

BB10012 and BBGC2 (12 volt 100 Ah) – 31 pounds

BB5012 (12 volt 50 Ah) – 17 pounds

BB5024 (24 volt 50 Ah) – 31 pounds

Lead acid battery manufacturers will state: “do not mix old and new batteries. Doing so will reduce overall performance and may cause battery leakage or rupture.” They also recommend replacing all batteries within a bank at the same time.

A partially used lead acid battery will drain energy from a new one, reducing the total amount of battery power available.

This is not the case with Battle Born LiFePO4 batteries. You can add new batteries to your original Battle Born bank up to two years down the road without damaging, reducing lifespan, or harming them in any way. 

As an update to this video, our batteries come with a 10-year warranty (8-year full replacement manufacturer’s defect warranty and 2 years prorated).

They are designed to last 3000 – 5000 cycles, at which point the battery will still hold 75 to 80% of its energy capacity.
