i use the pro peak constellation and it is awesome! i recommend it. i use it for all my batteries including ants, feather, beetleweights and drill batteries. it can charge a wide variety of battery types at 0.1-7 amps, it'll charge your lead acid batteries nicely aswell. it has a cycle function aswell, i'm currently cycling a 24v nicad

going to try trickle charging my c5 battery as it currently lasts for 3 miles at best when i get the correct adapter.
