1 MW
I have an unbalanced pack. Opened it up to find 9 groups at 4.07V, and one group at 2.20 volt. For academic purposes. I brought it up to 3.96 volt and it may go higher, but I stopped charging.
There are various things I can do going forward, like bringing all the cells to max charge and seeing if the cells all hold up, I can also see if the group drains just sitting there, or if the BMS was draining it. I can replace the BMS if that were the case
All moot if the cell group has been damned by its trip to low voltage land.
What say you guys. Is the battery damaged goods now? They are chinese generic cells, so no spec sheet is available.
