Best In Class
It’s not just that their products are best in class, their customer service is the best I’ve experienced anywhere at anytime by far.

Excellent Value
Wow! Amazing battery life. I ran my RV refrigerator for over 48 hours on a single battery and it still showed FULLY charged. Easy swap. I changed out 2 working lead acid batteries that would not hold enough charge to run the fridge for 6 hours. Very happy with this battery.

Life With Lithium Is So Much Better
I researched different brands of LiFePO4 and knew I needed Battle Born—with the best BMS out there! I bought with confidence and am amazed with the performance, even in the West Texas desert!

Highly Recommend
I have had my Battle Born Batteries on my boat for over two years now. These are great batteries for trolling motors. I can troll all day on a single charge and still have battery life left. Highly recommend.

These Batteries Are Awesome
These [Battel Born] Batteries are a great replacement for my old lead acid batteries. My absolute favorite feature of these batteries is not having to worry about 50% depth of charge. I can bring my batteries down to 0% and enjoy the full battery.

Great Batteries
Arrived quickly, they were easy to install in our RV, and everything worked the way it should. They hold their charge really well, are maintenance-free, and so much better and easier than acid-based batteries. Very happy with this purchase!
