It sounds like you guys have it figured out about the voltage an stuff, why does my volt meter say to recharge at 9.5? I'm kinda weiry about flying below 9.6, but whats been said makes sense. But i'm not sure i want to take a chance like that with a 2500 dollar toy or not. But it sounds like i have been just useing half of it power. Its like filling your truck up an only useing a half a tank an going back to feel up agin, never useing the lower half. In not going below 9.6 volts i hope i have not developed a memory yet in my ni-cd, cause i still want to use it as a back up battery. The input has been great guys thanks..............
