Renogy 12V 100Ah LifePo4 Battery - 1 Bad Row

These batteries have a good BMS and 1 out of 4 groups of cells is bad. You will be able to recover 3 groups of 3.2v 100ah cells and 1 4s 100a BMS. We already used a dremel to cut open the lid so you don't need to do any cutting to open this up.

These batteries were mostly never cycled. They likely were manufactured with 1 bad cell.
