I fly a DJI Flame Wheel with the Naza M V2 GPS. I have been using 3s 30c 2200mah batteries and getting about 5 minutes of fly time. I figured if I used a bigger mah battery, I would get more flight time. I purchased 2 ZIPPY 3s 30c 8000mah batteries. This should give me 12 to 15 min of flight time RIGHT.

I still only get the 5 min I got with the 2200mah batteries. When I charge the batteries after flying, it only takes 2100mah to fill the battery.

Why can I not get the full mah out of the battery?

Shouldn't I be getting about 7000mah out of these batteries?

Am I not setting something right in the assist software or did I waste money on the 8000mah?

HELP I'M GOING CRAZY TRYING TO FIGURE THIS OUT
