My old batteries were starting to show their age so I bought a few new ones and tested them today. Starting the timer when I start the motors, the Hobbymate auto-landed at 14:40 and the DJI Phantom battery auto-landed at 15:57 flying the Phantom 1.1.1 bare bones with 9443 props. Using 9450 props resulted in about one minute less flight time. At $13 each, the Hobbymate is about half the price of the Phantom battery. As long as it doesn't puff up I'll be happy with it.
