I thought I charged it over night, but I forgot to plug the second cord into the charger. I took my Phantom FC40 out into a field, flew it around for about five minutes, landed it, the light on the back turned red. At that point, the props would spin but wouldn't take off. I took out the battery and put it back in, the same thing happened, but it started to beep loudly and the props wouldn't spin. I took it home, plugged the battery in properly using the DJI Wiki, and let it sit for a while. According to the lights, it was discharging to balance. 6 hours have passed since then, and the same lights are blinking. I know I'm not doing anything wrong, since I found a replacement battery I forgot I had gotten, and did the same thing. It fully charged within 45 minutes. Help!
