I have a 16s5p pack with about 450 cycles. I have charged this pack pretty consistently to 67.2 sometimes a little lower.
Overnight a couple of days ago my pack would only charge to 65.8v. I rode the bike and tried charging again and again 65.8.
I took the pack apart at and measured cells and all were 3.57-3.58v
. Put back on charger to try to charge fully but again charge stops at 65.8v
I then disconnected the sense wires while the pack was charging and plug back in and pack started charging. I was able to get the pack up to 67v then shut the charger off. I then removed the sense wire at full voltage and let the pack sit overnight. When I inspected this morning the pack voltage had dropped down to 65.8 again.
I don't know what is going on, can anyone guess what the problem might be?
