Camcorder Voltage
Has anybody figured out what the acceptable voltage range for the camcorder is? Obviously 3 volts works. It also works on USB voltage through the USB port. That's 5 volts. Will the camera handle 5 volts through the battery connector? I am wondering, because it would be nice to use a 3.7 volt LiPo for aerial shots?

You could try and feed the 3.7v in to the USB power hookup. Can't damage anything and it's worth a shot. Worst case scenario you put a 3.3v voltage regulator between the LiPo battery and the battery inputs.
