Lipo batteries will not charge up if you let them run down completely.
You always need to have some power left in them so they can be charged up again.
If you can try another battery in it and if that works don't let your battery run down as far again
The batteries in these cameras have a small battery protection circuit board soldered on their output taba (and wrapped in tape on the end). This circuit will open if the voltage during charging is too high or the voltage during discharge goes too low. So, there should be no damage to the battery if you let it run until it stops. It shuts off at a higher voltage than my plane speed controller does.
