hi there I have a h920 with the A10 charger and I have a few questions, one question is will lipo storage mode bring the battery down from 4.20 to 3.83 or (50%) also with battery storage mode bring a low battery up to 50% I tried running a low battery on sotrage mode and it seemed to keep it at 3.79 or 30% is it ok to store for a few weeks at 30%? I know storing a full 4.2 for more than a few days is a no no.
