I have noticed when checking my Flytrex data that even known good batteries can have very erratic voltage levels. For instance when you do a hard climb, the motors demand more amps. With some of my older batteries the voltage drops quite a bit doing some maneuvers that spool up the motor speeds. I am almost certain that I had an auto land incident because of this. I didn't let it auto land and flew it on home without incident. I have been keeping a close eye on that particular battery when flying to make sure I don't have any more exciting incidents. But I have had this message pop up a couple times lately, "Not enough power to Return Home" but in reality I was able to fly it home. I think it is because as batteries age, they are less able to cope with higher amp demands causing premature low voltage alarms. Meanwhile I do take precaution and land asap whenever I see anything like that happening. The battery I suspect as my worst one only has about 50 cycles on it, even though I have been very careful with it's care and feeding. It still shows about 88% life left which is a result of it's internal resistance rising with age. That one should still be under warranty but I haven't had any luck dealing with DJI in the past, I don't expect that will change.Has anybody else had this? My klaxon is going off at 55%. Not only on one battery but both of them. Which could indicate a fault somewhere.
Any advise appreciated.
