I hope you realize that you can only charge at 15A total with the Hitec even though the box says 10A on each channel. The power supply is under-sized. You also can only do 1S lipo on the first channel. If you race 1/12 this is a big problem.

The Reedy 1216 C2 /Ultrapower does a real 12A on each channel (24A total)and it does 1S~6S on both channels. The fan is also temperature controlled, so you don't have it screaming full blast all day.
