Battle Born Batteries is a lithium iron phosphate (LiFePO4) battery brand from Dragonfly Energy, based in Reno, Nevada. Battle Born became widely known among RVers for drop-in 12-volt lithium batteries with a built-in battery management system (BMS), designed to replace lead-acid batteries in the same space.
Installing Battle Born in an RV
A drop-in lithium battery fits where a lead-acid battery was, but the rest of the system needs attention:
- Converter or inverter-charger set to a lithium-compatible profile, or replaced if it can't be. See converters and lithium.
- Solar controller set for lithium. See solar battery basics.
- Alternator charging on motorhomes and tow vehicles. A DC-to-DC charger is often recommended.
- Fusing near the battery, sized correctly.
- Battery monitor with a shunt, if you want accurate state of charge.
Battle Born publishes installation and charging guidance on its site. We follow the maker's guidance for any lithium battery we install.
Cold weather
Most LiFePO4 batteries, including standard Battle Born models, should not be charged below freezing unless they are heated models or the system prevents it. In most of Florida that is rarely an issue, but Panhandle and North Florida freezes happen. Check the model's cold-charging behavior. Battle Born has offered heated versions.
Why owners choose it
Usable capacity, low weight, long cycle life, and a well-known brand with US-based support. It is also usually more expensive than some newer lithium brands.
