Tello shows battery is empty

[Anafen]

Hi,

I had this problem already twice. I charged the 3 batteries yesterday. Today I want to do a flight but after connecting to Tello wifi and than launching the Tello app it shows that the battery is empty on all 3 batteries.

Does someone have any idea what is going wrong?

Thx

Maybe try on the Tello FPV app to see if it shows the same, your charger would be my first guess.

It is the same on TelloFPV. The strange thing is, when I plug them back in the charger hub they are charged in couple of minutes what means they were not empty at all though in the apps the battery icon shows red. It drives me crazy.

Now they show back 100% on both apps. Strange

so either all 3 batteries are (almost) dead - or your Tello has trouble reading correct voltage

The Tello is brand new. Do the decharge or lose charge when not in use perhaps?
