Just finished this video today even though I filmed it in November 2015. Figured out that a Turnigy Multistar 6600 mAh 14.8 V 10 C battery fits perfectly in the battery bay of a Phantom 2 shell. The rest of the components of my Phantom are that of a Phantom 1.1.1 with 9450 props. This battery gave me 24 minutes of flight time before being completely exhausted and causing my Phantom to have a hard landing in a tree. I figure I could safely get about 20 minutes of flight time with this single battery. By the way, all NAZA settings are completely stock. I flew the Phantom aggressively as I could in this video to try and simulate real time flying conditions as I've always felt the battery tests where the Phantom just hovers doesn't really give you a good representation of what the flight time would be like. Hope this helps you guys get a little more flight time out of your Phantom!! Enjoy!
