That junkie tenergy universal smart charger is going to mess up your Lipos.
If you want a budget but good charger, icharger is one of the best. (better than Imax B6) There are others, but for what you are using it for this is very good. Your Lipos will last longer with it.
I own several chargers and the best are icharger and PowerLab by Revolectrix. (I charge 2S to 12s packs)
