He states it's not officially rated for a 2s 7.4 volt battery, just think about it you MORON if it gets roasted by your 7.4 volts they won't replace it because you are running an unofficial voltage to it and when you send it in they will see that it was electrical damage that wouldn't happen from 6.0 volts. I have several racing friends that ran there 7955's on 7.4v and went to a high voltage servo after toasting the 7955 and hitec refused to replace it. I guess you have more money than brains, IDIOT.
