after a full charge (according to the green light on the charger) the battey voltage was 10.4
after running the heli for less than 1 min the voltage reading was down to 8.3 (obviously not enough power to lift off)
after letting the battery sit for about 15 min the voltage had raised up to 9.28 (don't know if that is normal)

from my previous experience with the orginal battery i am sure you are going to tell me this battery is bad too since its not reading 11.1 but what is killing the batteries? is there anything else I should check?
