I am running Maxamps and a Hyperion charger. Both work great, I can't say they are the BEST, as I have had no reason to try anything else, because they work flawlessly, and the same for others around me. It is nice to have an AC charger, instead of buying and screwing around with a power supply.
I am not knocking the other chargers, but do any of the lipo users need the laundry list of options on the other popular chargers, that also don't include AC and a balancer?
