I have a megapower charger.
I charge my batteries from 12 to 20 amps.
The problem is getting a good Power supply!?!?!?!?
Don't know why they have high powered chargers and no power supply to feed them.

But if you want a simple and easy charger no power supply get the dynamite passport ultra, charges up to 8 amps and good customer service from horizon.

But if you want to be a little cooler check hobby King and they have some really good chargers but you will need a power supply.
try this: TURNIGY MEGA 400W Lithium Polymer Battery Charger
