UNBALANCED - 12.8v 6.4ah 82ah Lifepo4 module with 10a BMS
Here are awesome little 12v lifepo4 battery packs. These particular modules all have voltage but they are out of balance and priced accordingly. It's possible you can balance these again and the pack will work perfect but it's not guaranteed. You get a quality 10a Lifepo4 4s BMS and 8x 26650 3.2v 3200mah lifepo4 cells for just $14.99. These are used packs. The cells seem to be a generic brand but these packs were made for a popular company so the cells should be decent quality. We also tested a few packs that were balanced and they were between 80-100% capacity. These packs we can't guarantee capacity since the cells are out of balance. It's possible they are out of balance because of a low capacity cell.
