I madae these 3s2p packs, or 12 volt 18650 packs using 6 cells to power my laptop. I use two packs in series for 24 volts and that powers my dell notebook.
I noticed one of the parallel groups or two cells is draining much lower than the others on one of the packs, like .2 volts with half use and I assume it is a bad cell.
I used the panasonic ncr18650b cells on these packs a couple of years ago.
My question is, after I break apart the cells and find the bad cell, do you see any issues with replacing it with a new Sanyo NCR18650GA 3500 MMAH cell? I have some of these laying around from my ebike build and figured I would use one of them. They will have more capacity then the older ncr18650b cells used in my 3s2p packs for sure.
The question is does it really matter about replacing the one bad cell with a probably higher capacity cell? Or should I try and match it?
I balance charge these packs every time I charge them so I don't see any big deal but just thought I would ask.
Thanks
