I don't know if I'm in the right place. I bought the Dji Air 2s Fly more from you today and wanted to charge the normal standard controller. I first pressed the power button and saw that two of the four lights came on. Then I connected the charger and it started charging. After about half an hour, nothing was flashing any more, so I thought that the controller was charged. I removed the charger and pressed the power button again, but there was no reaction, no light or flashing. I used the original charger and cable.
