| When adding or replacing cells try and discharge them (old ones and new ones separately) to a voltage of eg 0,8 V / cell, then solder them together, then cycle them a few times at low current as if you were forming a brandnew pack.
Otherwise you might fry cells whilst charging, or reverse the ones with less capacity whilst discharging, both will probably kill them.
Some say you should *never* add or replace cells to/in a existing pack, but I think if brand and (real, not printed-on) capacity matches, it will work.
At the first fast-charge cycles I'd have a thermometer handy and watch the pack closely.
