The easy way is to put them in a turbomatcher
.
There are a couple of other ways though. Often when a cell goes bad, it will get extremely hot while it charging or discharging, so keep an eye out for that. Assuming that doesn't work, a more tedius method is to disassemble the 4 cell pack in question. Take a 4 cell pack that works, remove one cell from the working 4 cell pack and replace it from one from the faulty pack, try cycling the pack, if it fails, there's your bad cell, if not, keep trying to you find it.
