Hey Dashan, where were you?
Curious to hear how this works out!DIY liFePo4 battery.
I wanted to have the ability to use a 3 quart Instant pot inside the van, and also make coffee in the morning. I decided to build a LiFePo4 battery.
I bought 4 pieces 202AH Lishen battery cells from Alibaba.com (Lishen 202ah LiFePo4), paying a total of $340 shipped to my door.

You are right, it's the principle.So, it looks good and is a good amount of power. That said, it's needling me that you have 3 smaller-gauge red wires hooked to the positive terminals and one smaller-gauge red wire hooked to a negative. I know it doesn't matter, but it still bugs me! 😁
