I have a battery that does not want to be charged, does not light up... I left the battery in the charger for 3 hours and there is no result. When checking the cells in the battery, I found the following, one of the cells has a very low current. My question is.

1. Can I do something about the battery?
2. If I charge this cell somehow directly by jumping the board(bms). and then I try to charge the battery (the normal way), will that work, or can I damage the board?
3. I know if I remove the batteries from the board it will lock up right? what if the battery volts are too low, like mine is right now, will that cause the board to think there are no batteries on it and it's already locked out? If so, is it my only way to get it work is to buy hardware(like cp2112)? can i revive her without buyng tools ?
