Renogy 48v 50ah 2.56kWh RBT50LFP48S - 1 Bad Cell

This battery just has 1 bad cell. All the other cells are sitting at 3.35v. The BMS is good too. So 15 out of the 16 groups of cells are good to go and the BMS. The lid comes off easy with screws and there is easy access to everything. If you can replace the 1 bad cell group with a 50ah battery you will have yourself a $1500 battery with heating and all the bells and whistles you could ask for.

Note: the other cell groups should test around full capacity. We have been testing this same pallet of batteries and all the batteries that were balanced tested around 97% capacity so this is not a heavily used battery. Pair up with a 48-50ah lifepo4 battery to replace the bad cell group and you should be just fine.
