Is the TEU-101BK not able to be used with a 7.4v lipo battery? I have been trying to get one of these ESC's to work in my Rally Car but it doesn't seem to want to work with a 7.4v lipo battery. It works perfectly with a 6 cell nimh battery.

when I connect thel lipo the steering works but the ESC just flases red and beeps. Is there anything that can be done or are these ESC just designed for the 7.2v nimh batteries.

Thanks,
Larry
