The Turnigy charger is easy to use for me, but I have been doing this for many years. I do know the instructions are pretty hard to understand. I tried to read them and got nowhere, so I just played with the charger until I figured it out. It really is easy if you just make sure it is set for lipo charge and do not exceed the recommended charge rates for your battery.
