12V 400AH LIFEPO4 LITHIUM BATTERY

DIY LIFEPO4 LITHIUM BATTERY ACCESSORY

For our BWB LiFePO4 Batteries, we only use A-Grade GFB Prismatic cells and JBD BMS. Apart from that, we also use double-coated 3M foam tape between every cell for shock absorption, fiberglass tape to keep the cells together, and high-quality epoxy resin boards as the insulation board.
The cells are covered by foam on both sides as well as the bottom to help with vibration and external heat. In this way, the battery is built for performance in a harsh environment related to 4WD and boating.
BWB LiFePO4 Batteries are so Tough and Strong, that they will accompany you and your family to enjoy a relaxing time.

  1. First trip with the new 400 amp we have been free camping for 3 days with mostly overcast weather, the battery is working very well and takes solar charge very good.

    • We are so happy to hear the battery is doing so well for you.
      I hope you had a great time camping.
      Thank you for the positive feedback!
      Cheers Big Wei Team

  2. Seems like a great battery so far

  3. A little expensive now that Lithium looks like being superseded , but by no means over the top
