Parts/Repair 12v Lifepo4 1x ICCNexergy 38.4ah 2x Powersonic 45ah

Here are 3 batteries for parts/repair.

One battery is an ICCNexergy 12.8v 38.4ah Lifepo4 medical battery. This one seems to not be charging fast enough. Has voltage. Possible bad BMS or just 1 bad group of cells.

The other 2 batteries are PowerSonic 12.8v 45ah medical packs. One doesn't charge so likely discharged cells or a bad BMS. The other charges but when you stop charging the voltage drops to 0 so this one likely has all good cells but a bad BMS.

With these batteries you can salvage most of the cells, most of the BMS, and all the enclosures. Great value overall at this price considering the value you can recover from these if you have some time to mess around with them.
