Description

This is a 4s LFP (LiFePo4) cell holder, to make a 12.8v (nominal) battery, from inexpensive C40 cylindrical cells.

 

The C40 cells are currently (early 2026) very cheap on sites like AliExpress. I bought B grade cells and mine came out about 17Ah, which is not bad for the price and size
