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.

Battery switches or “master disconnect” switches are a common item in RV or marine systems and 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

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.  

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 a charging voltage of 14.2-14.6 V and the float voltage of 13.6 V or lower, then it will work perfectly with your Battle Born Batteries.

Minn Kota multi bank chargers are very popular with anglers and are know for reliability and ease of use.  Another advantage is they work great to charge your Battle Born Batteries.

Although these models don’t have a specific lithium setting, they work well in the AGM mode for “pc” and “D” models. In addition, you can leave these chargers plugged in for long periods as the float voltage is about 13.6 volts and will not harm our batteries.

Battle Born Batteries are sealed and can handle being in a moist environment. Our batteries, just like any electric device, should not be submerged in water.

Upon request and as an upgrade to our standard battery, we will add a waterproof seal, giving added protection from moisture and more extreme marine environments.

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

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. 

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.

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. 

Our batteries allow a max 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 max recommended charge rate of 150 amps.

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.

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.

If your battery registers between 0 to 5 volts this means that it’s 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.
