Needs BMS + Lid - ICCNexergy U1-40 Lifepo4 12.8v 38.4ah 491.52wh

These batteries are balanced but they need a BMS and the lid is missing. The 4 series of cells inside are balanced and there is already a balance lead wiring harness. Replacing the BMS is very convenient on these packs. Or you can series them into higher voltages after top balancing and add one overall BMS. They came out of medical computer carts so they use one of the highest quality 18650 lifepo4 cells available.
