Hi all - I'm new to the forum and Tello
Recently bought a used Tello, without battery. I purchased a fullymax from B&H.
Battery cam in with a charge of 2.75 volts.
Question # 1 - Is this battery ruined forever?
There are a lot of battery issues on this forum.
Question # 2 - Does battery quality pose a problem to many Tello owners?
First turn on - green lite for ~5 sec then 4 or 5 red flashes - then nothing. Will repeat if batt is removed, reinserted
Tello initially would not charge the battery. I rigged an external charger- brought battery to 4.2 V.
With OEM battery, Tello will not turn on before or after charging - no change after charging.
Following some info on this forum - I plugged into PC via USB while holding down on/off button.
Attempted to upgrade firmware - fails on last step, when sending firmware to drone 'an error has occurred'.
Any suggestions?
- Did I get a bad drone?
- Did I get a bad battery?
- Is it appropriate to try to upgrade firmware? filed with both apple and android app
- Try a new battery?
Please comment
