Hi,
I have the FlyMoreCombo and one of the extra batteries failed after 6 flights. Red flashing status light and in the android Go4 App it says "broken cell, pls replace battery"
I had a look to the cells in the app: after fully charged the Batt. : 4.17 4.33 4.32 :-(   Btw, I've never flown below 30% and YES I'm on the latest FW / APP!
And now with 75%: 3.94 4.09 4.07 ....
Will a full discharge / charge solve the problem?

Take battery down to 10 % then charge back up. Should balance cells.

Thanks, will try tomorrow ... maybe I have to DIY a 100W load and get that batt. connector in case it happens again on an other battery ... who knows :-/

If did not work. Battery has 6 month warranty!

Please keep us posted.

Unfortunately no success.  After discharging to 0% = 3.25 3.64 3.63 and then a full charge (all Batt. lights off) the reading is: 4.17 4.34 4.33 ...
Looks like before ... RTS

For your flight safety, I'd suggest you to send it in for further evaluation.

Send it to DJI, you've got more batteries to keep having fun, and they'll replace it I guess. It's on warranty!
