I'm disappointed with a constant 11 minute flight time from say 95% battery down to the first set of red lights at 30% on my Phantom 2. My voltage according to my iOSD mini and Black Pearl setup starts out at around 12.2 V and seems to get down to 11.2 V fairly briskly within a few minutes of flying. In all my P2 is nothing out of the ordinary, just a P2, H33D gimbal, Hero 3+, Immersion RC 600mw, iOSD mini, Fat Shark Spironet V2...... I see people on here getting 14-18 mins on average, possibly more in some cases, yet my average easy-going flight would get little more than 11 minutes? Maybe we could factor in a little bit of wind but I am sure it can't be something that would cut down flight times significantly by minutes. What's the deal, the batteries appear to be in good health according the DJI Assistant on my PC. And before anyone asks, I follow the general consensus on looking after LiPo batteries, I.e. Try to store them at around 50%, etc. Is the P2 itself the cause?
