That thread is comical, poor Jason doesnt have a clue about... anything really.
I also find comical MA's 4 points about why C ratings are no good anymore; if a continuous current of ~100amps or so is enough to ruin the battery, wires, plugs and give you a 90second runtime, then how is some bollocks ~600amps+ surge rating with no info on duration any more useful? 600amps being pulled for any longer than a few milliseconds will destroy ones entire setup. It beggars belief they havent been taken to court before now for false advertising and encouraging dangerous usage of lipos...
