Are Battle Born Lithium (LiFePO4) batteries superior to AGM batteries for electrical system of campervans, RV, boats, etc? To find out, we replaced the battery bank of our campervan (230Ah AGM) for Battle Born Batteries (200Ah LiFePO4 Lithium) and we've been testing them FULL TIME since June 2019. Here is our review.

1- Jumping to Conclusion

Overall:
4.5/5

"Technology has come a long way. Going for Lithium (LiFePO4) these days is a no brainer as it provides more usable capacity in a smaller package. We, ourselves, upgraded from AGM to Lithium and we're glad we did. Highly recommended!"

4- Lithium (LiFePO4) VS AGM

Comparing a 100Ah Battle Born Lithium battery (100% usable capacity) with a 200Ah AGM battery (50% usable capacity):

 210Ah AGM100Ah LITHIUM
USABLE CAPACITY100Ah100Ah
WEIGHT133 lbs31 lbs
TOTAL LIFE CYCLE*12003000
UPFRONT COST$650$950
COST PER CYCLE*$0.54$0.32
LENGTH21″12.75″
WIDTH8.5″6.875″
HEIGHT9.5″9″

*For full time Vanlife (1 full cycle daily), it means an AGM battery will cost roughly $200 per year to operate and will last 3.5 years; while a Battle Born Lithium battery will cost roughly $120 per year to operate and will last 8 years.

5- Camper Van Wiring Diagram & Electrical System

Designing and building the electrical system of a camper (van, skoolie, small RV, etc.) is by far the most overwhelming task of a conversion… trust us we’ve been through that! To get you started, we made our own wiring diagram available and wrote an extensive Electrical System Guide:

6- Reliability of Battle Born Batteries

Battle Born Batteries come with 10 years warranty.

We installed our Battle Born Batteries in June 2019 and they’ve been working flawlessly since then. Subscribe to our Mailing List to be notified if anything happens!

NICE TO MEET YOU.

About-Us-Narrow

Hello! We’re Isabelle and Antoine 🙂 In 2017, we sold our house (and everything in it), quit our engineering careers, and moved into our self-built campervan. We’ve been on the road since then, and every day is an opportunity for a new adventure; we’re chasing our dreams, and hopefully it inspires others to do the same!
