I find it odd that the only way to discharge the batteries down to low voltage cut off deals with flying the copter or leaving the copter on. I would think engineering wise you would want to find a way to do this battery maintenance by not adding running time on to the aircraft's system. I know they say it takes the auto discharge 2 days to get down to a level below 65%, I wish somewhere in the circuit they could have a bigger discharge something that you could do by holding the batteries power button on for 30 seconds and that would trigger a complete discharge that would take a day to do. Or if there someone out there came up with a discharge unit that you could attach to the battery and it would automatically bring down the voltage to zero or a safe storage 65% So my question at this time what is the best way to bring your batteries down for full discharge on the 20 cycle maintenance requisition???
