Battle Born Batteries Review: 12V Lithium (LiFePO4) For Camper, RV, Boat, etc

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!"

3- Battle Born Batteries Specifications

BMS Parameters

The Battle Born BMS won't allow charge/discharge out of these values:

Discharge

Charge

Temperature

Others

*100 amps continuous discharge current PER BATTERY (parallel). This means:

BATTERY QUANTITYCONTINUOUS DISCHARGE CURRENT ALLOWEDMAX INVERTER CAPACITY
1 (100Ah total)100A1000W
2 (200Ah total)200A2000W
3 (300Ah total)300A3000W
etc.etc.etc.

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.

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!

  1. Have you guys had issues with your maxxfan after installing battleborns? I’m reading mixed reviews on how people with higher voltages have maxxfans that turn off because they’re technically limited to 13.7v. So some have to install a voltage regulator to fix it. I switched to battleborns and my maxxfan has a voltage trip and turns off.

  2. Hey Antoine, really benefiting from your work on this site. My van build is following you a lot. Based on that I am planning on using the Samlex SEC1280-UL for shore charging my Battle Born Li batteries. However, the Samlex instructions all talk about lead batteries and Amazon comments don’t recommend it for charging Li batteries. But… your review here says can use the AGM setting and Float not required because BMS will turn off charge. Is this the simple victron (vs Simarin system) that is actually turning off the charge or am I missing something?

    • Battleborn themselves say the Samlex is compatible with their batteries: https://battlebornbatteries.com/charger-compatibility-table/

      “Most Samlex units work great with our batteries, especially if you set the charging profile up in custom mode. You will want the bulk/absorption to be 14.4 volts float at 13.6 volts and disable equalization and temperature compensation. If there is not a custom mode, the AGM setting will work well to charge our batteries.”

      It is not required to float Lithium batteries, but that’s fine if you do.

      Hope that makes sense, cheers

  3. Just bought your wiring diagram (and other stuff). Your site is awesome, as you likely know.

    I can’t find a pic of your electrical systems setup. I assume you have a central electrical systems area where everything is locked down (batteries, charger/converter, etc.). Am I missing that on your site?

    Thanks in advance.

    • Our setup is customizable and can be further expanded later if needed. With a Goal Zero, there are far more limitations and it’s harder to expand later. It’s also much more expansive.

  4. Hi Guys,

    From your “3- BATTLE BORN BATTERIES SPECIFICATIONS” and “4- LITHIUM (LIFEPO4) VS AGM” it seems to me that one Li battery is equal to one Pb acid. But you got two (I think, only based on your picts, I dont think you said that). I realize that 100 Ah doesnt equal 210Ah, but you can only use 50% of the 210Ah.

    I must be missing something.

    Confused, Don
