How about a combination charger/balancer. The ones I use are from www.fmadirect.com. These charge through the balancer connector and are extremely easy to use with readouts on just about everything that is happening. Adapters are available for the different brands of LiPos. The Cellpro 4 sells for about $70 and adapters are about $10. I have both a Cellpro 4 and a Cellpro 10. I've had a Cellpro 4 since they first came out. The Cellpro 10 is much more expensive but charges up to 10 cell packs or two five cell packs at the same time. Both chargers have storage charge mode and a mode for A123 cells.
