Am desperate to see what happens in this thread. I have a fairly new (4 month old) drone and fly-more kit......all batteries only charged about 8 times. Now 1 works and the other 2 have stopped working....same thing ....completely dead. No light, no response, tried charging in hub, directly, in car.....nothing. The only thing I have noticed is when I put the working 1 into hub, light changes from yellow to green.....but either of the 2 non-working batteries, hub light changes from yellow to red. Going to see store on Saturday.
