I have a pack of 18650cells, which is made up of 2 6s blocks with a fuse inbetween. Each block has balance lead that I hook up to a CellLog. One wire broke off, so that rendered one of the balance leads useless, but I didn't think it mattered for the most part.
I bulk charge the 12s pack and stop when the CellLog beeps at the programmed 4.20V. So, in the end I'd have 50V.
I decided I'd resolder the lead back, and when I checked that pack, all the cells were at 4.18V after my ride home. However, on the other pack, the cells were at 3.87V
Is it normal for one pack to be so different than the other?
