I bought 19 x Pylontech US2000 B Plus and H48050 Power Cube Batteries as Spares or Repairs.
I have fixed 15 of them so far, but I have 3 potentially available for spare parts, (the other one i'm attempting to recover).
The boards appear to be similar in purpose across the range with the triple battery packs in each units '15s' 'battery'(being made up of 3 x 5s2p packs).
I'd think that the mosfets would be the type of ones in all cases?
I actually cut out individual cells packs, tested and rebuilt one of the 5s2p packs to make a perfect working one from the best of the salvaged cells.
