Balance packs before or during the charge, never after. If you carge an unbalanced pack fully, one cell could go over 4.2v. I like the balancers (v balance, lba10) that you can charge thru. That way the balancer has control over the charge, and if a cell goes over 4.2v the balancer can interupt the charge. really safe that way. Plus you spend less time, as the balancing happens during the charge. Almost every time I charge the balancing is done before the pack is fully charged.
