HealthyDrones is reporting that the original battery that came with my first Phantom 3 Advanced, (purchased Jun 18th, 2015), is showing "Major Deviations".
The battery life sez 93%, with 44 total flights, 38 total charges, and 5h 20m 43s of flight time. I've calibrated the battery three times over it's 78 week life, the last time was a couple weeks ago after the "Major Deviations" were reported after each flight. On the (very careful) flight immediately after the last calibration it flew without "Major Deviations" being reported. But "Major Deviations" popped up again on the next two flights, so I've grounded that battery (not electrically, I just won't fly with it any more ;o)
Max. temp recorded for the battery is 129.2°f which is about average for my other three. The battery is clearly out of warranty, so I'm mainly concerned if I can expect the same problem with my other 3 batteries as they approach 5 hours of flight time.
For a replacement: I see that the newer 3rd party batteries from Powerextra are getting some pretty good reviews lately. I'm not quite convinced, but would love to hear any fresh opinions on that. With my authentic DJI battery unusable at 93% life after 44 flights, I wonder if Powerextras could be any worse and still be in-business.
