I have a Phantom 2 | H3-3D Gopro Hero3+ | AVL58 | iOSd Mini | FPV Hub. Most people with this setup are claiming to get around 14-15 mins. I am getting anywhere from 9 to 11 mins. The only thing I can think of is the battery? When I turn on the Assistant software it flashes a popup on the screen for a second and says that the battery is not authentic DJI, but quickly disappears. Do others get this message? Its quick and in the bottom right of the screen. Any way to improve flight time (besides the obvious, like removing weight)? Keep in mind I only let the battery get down to 26%-28% before landing. Thanks!
