has anyone used this charger? if son any comments, pro and cons? thinkin about picking one up, it charges lipo,nimh and nicd. is capable of charging 2 packs at a time, but not sure if i have to run a seperate power supply to charge at 5 or 6v solid for each pack. i think it will break the voltage up to 2.5 for each pack if not. so anyway it looks sharp and i would be getting a deal so any info is helpful
