These are good chargers. (For charging your Li-RX-Packs) It comes with all kinds of plugs, even a glow driver adapter for charging, and USB to PC adapter, and a Heat Sensor. Been useing one for a year now. I even charge my Rideing lawn mower battery.

Can you charge two 2s packs at once? I was looking at the specs but could not tell if it would do two packs at one time. Also does it show you how much is in the A123 cells?
