ISDT chargers are very successful, like the Q6Plus (see test here), but you have to use an external power supply since they do not have one. The 608AC is a little larger but includes a transformer, for connection to a 110V or 220V outlet. It is capable of charging, with balancing, Lipo, LiHV, LiFe, LiIon batteries in 1S to 6S, Pb and NiMH. The charging current is adjustable from 0.1 A to 8 A, for a maximum of 60 W. This charger, compatible with BattGo batteries to take advantage of some additional information, is available for pre-order at $59.90 at Banggood.
