An overland application is all about allowing modern explorers to get off the beaten path. These vehicles let you find a greater sense of self-reliance and focus on the journey. That journey can take you over rough road, overgrown road, or no roads at all.
Overlanding is all about exploration and venturing to the remote parts of the map where most don’t dare to go. Modern overland vehicles don’t fit any particular mold or vehicle type. Rather they need to be reliable and resilient with ample clearance and the ability to handle any terrain.
At 31 pounds, a Battle Born battery will keep your overland rig light while still being robust enough to perform over any rough trip. Our batteries give you the ability to fully discharge 100% without risk of damage or memory. They are capable of being charged up to five times faster than a lead acid or AGM battery, and come with a 10-year warranty. Our batteries, components, and accessories will allow you to run your LED lights, navigation equipment, radios and more over the course of your adventure.
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.
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.
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 minutes per battery (if it’s an option)
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).
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 minutes per battery (if it’s an option).

Answering this question can depend on the amount of space you have on your vehicle 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.
In some cases, you might have to replace the current converter/charger that come stock in the application due to the output voltage of 13.6 V. Some very common WFCO and Progressive Dynamics converters will rarely get to their higher boost of 14.4 volts when a lithium battery is connected.
Although these converters will charge your Battle Born Batteries (very slowly), they may never get to a 100% state of charge and will not trigger the passive balancing effect that starts at over 14 volts.
In addition to their standard models, many converter manufacturers now offer LiFePO4 chargers and most are highly compatible with Battle Born Batteries.
Many RVer’s run into trouble in deciding which solar charge controller to choose and 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.
Second, 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.
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.

Alternator Charging for a Lithium Bank
Before discussing this topic please note that when connecting to a towable trailer (such as by a 7-pin connector) you typically get a low amount of charge into your lithium (aux) battery bank and an isolator or current regulating device is usually not necessary.
In motorized RVs, vans and skoolies, very often the alternator will charge lithium batteries at the proper voltage (14.2 to 14.6 V), but we recommend not to exceed a 50% charge rate, this means a max of 50 amps for each 100 Ah battery.
An example would be a high 220 amp alternator putting out its full charge to the electrical system. An alternator charging the starter battery, running the electronics in the vehicle, and if wired with thick enough cables, might have around 150 amps leftover to charge your Battle Born Batteries. In this instance, three of our batteries would be a good match for the alternator’s charge.
Some things to consider when connecting a starter (lead acid) battery to a lithium battery bank:
- 2 lithium batteries or less, you will probably want to use a battery to battery charger such as the Sterling product on our website:
- Higher amp units charge the batteries faster. These devices will not only regulate the charging current but also replace your existing isolator.
- For 3 or more lithium batteries connected to a starter battery we recommend our Li-BIM.
These are generalities, but if you give us the amperage of your alternator, the model of your isolator, and how many lithium batteries you are planning to use, we can give you a better suggestion as to what you may need. Call us at (855) 292-2831 or contact us at [email protected].
Battery Isolation Manager
The battery isolation manager (BIM) is typically used in motorized systems with 3 or more Battle Born Batteries. Lithium batteries tend to pull a lot of power off your alternator, which over time could cause it to overheat.
The BIM works on a duty cycle. It charges your house battery bank for 15 minutes, then taking 20 minutes to rest so your alternator can take a break and never has the opportunity to overheat.
Battery to Battery Charger
Battery to battery chargers are typically used in applications where you have 1 or 2 Battle Born Batteries. This is because our batteries have a recommended 50 amp charge rate per battery. If your alternator is applying a higher amperage to your batteries than the recommended charge rate, you will need to limit the amperage.
The battery to battery charger will limit the amperage coming off your alternator and will apply a safe charge to your batteries.
Both devices will properly isolate your lithium batteries from your starting battery.
A few years ago, it was very difficult and unlikely to run your air conditioner from a measure of batteries and inverter in an RV. Today it’s no longer a possibility but a reality, and many customers are experiencing the convenience that lithium batteries bring to your power system.
If you plan on running your air conditioner, Battle Born always recommends an EasyStart. The EasyStart can reduce start the current by 65-75% compared to a compressor’s LRA (locked-rotor amperage). These devices offer a solution that allows an air conditioner to operate on a generator, inverter, or limited utility power when it would otherwise not have functioned.
Our batteries are assembled and constructed with the highest quality components available. They are designed to withstand vibration and keep working for thousands of cycles.
You will need to check your connections from time to time (as with any kind of battery) to make sure they maintain good contact from cable to battery.
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.
Our batteries are drop-in replacements for typical lead acid batteries. This means that our batteries are designed to fit like a normal Group 27, 31 and GC2 battery in your bank.
This, however, does not mean our batteries are plug and play. Our batteries still may require specific components and programming to run your application.
To figure out if your components will work with our batteries, give us a call at (855) 292-2831 or send us an email at [email protected].
Our batteries are safe. All Battle Born Batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS).
The BMS protects the cells against excessively high or low voltages, high currents, short circuits, and excessive heat or cold. These are the most common causes of battery failures, and we have taken every precaution to mitigate these risks in all of our batteries.
In addition, all of our cells are manufactured in a state-of-the-art automated facility, and each cell is cycled multiple times to ensure quality and consistency.
Li-ion batteries can be safer than lead acid batteries, which have no protection against ground faults. Our built-in BMS that protects against ground faults.
We strive to include all the best safety features into our battery, and this is what makes us a leader in the deep cycle replacement market. We are constantly developing new innovations to increase safety in our batteries.
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 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.
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.
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.
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.
