I have about 9x 4s batteries, all with 3 perfect cells and 1 bad. Ide like to remove the bad cell from each pack, so i can use the remaining 3s packs for a trolling motor 12v battery pack for my canoe.
How exactly do I go about this? I've opened the packs, and it seems like there are 2 circuit boards per 4s pack. how do i remove the bad cells from these boards? If the bad cell is in the middle of the pack, will it still work? basically, all the cells are glued together, so how i would remove one from the group??. And they're soldered to circiut boards (2 cells per board. 4 cells per pack). I can determine what cell # is bad, and then follow the color wire from the balance tab to the individual cell, so i know which one is bad.
i just dont know how to remove the bad cell from the group physically. im afraid ill damage the cells peeling them apart bc they're glued, which would blow up in my face. im also unsure how to remove the battery from the "circuit boards". What do i cut? does anythign need to be repaired after removing the cell?
Thanks
