Hi,
After full charge something happened with the batteries. All three have the same problem.
- no feedback data (power, temp., voltage...)
- message displayed ¨Unable to take off¨

The dron powers ok but is not usable I guess because the battery status is not known.

Tried couple of charge-discahrge cycles on single charger, one by one, but issue is still present.

Please advise.

Regards

Hi Shtury, may I know the model of your drone, the firmware version of your aircraft, and the app version, please? I'd like to help you check it. Thanks.
