Hello everybody
I bought them at a Cheerson CX20 Copter.
Order No. 367181616
Today I have the Copter appended the first time on the battery.
It looks like it has triggered a short circuit in an engine.
This engine is no longer running.
The taste smelled burned.
The copter was never in operation.
Can you tell me what can I do?
I have the original packaging.
Many thanks for your help
With best regards
Hans Wydler
