Hi, I currently have the phantom and Goodluckbuy gimbal with the gopro attached and a fatshark transmitter mounted underneath. I'm getting aproximately 6 mintues before the low battery lights start flashing. Thinking I could improve the flight time I bought the dual battery mounts and and am running them in parallel. I didn't find any improvment in flight time, and if anything I would say it's worse. It was however below 32 degress outside. Anyone with any information on this subject and if I should have seen improvements would be appreciated.
