In another post I was attempting to repair a bad string of cells in a Discover AES 48V battery. After disassembling the battery and exploring my options it's looking like, short of radical "surgery", that the battery is toast. However, the way the battery is constructed there are 4 subunits of cells, each containing 4 parallel strings of 15 26650, 3.2V, 3.8ah cells (see attached photo). One of these subunits has a bad string but the other 3 are fine and appear to be fully charged. Rather than try to recycle them I'm curious if they could be reused and configured with a BMS as 12V batteries. It would be easy enough to connect the 4 15P strings in series giving me a 12V 57ah battery.
What would I need to do to do this? Any recommendations on a quality BMS? Are there any other components that I would need to do this safely? When I took the original battery apart there were 2 circuit boards besides the BMS.
