Hi, Just bought a Mini SE flymore combo. Everything works as it should except for one battery.

At first it refused to fully charge, with it stopping on the 3rd light and flashing 3 times. Today when i plugged the dock into charge, all 4 lights rapidly flash 3 times(see video).

From what I can see this indicates a battery fault. Is there anyway to resolve it? Can i just return the battery for a replacement? It wasn't immediately obvious on the service page if this was possible.

Cheers.
