Bought a phantom 4 today with 2 batteries and a battery that doesn't charge (seller stated this) it's got one flashing green light then goes off. Take it that it's been discharged too much? Any fix for it?
I’ve had a friend do it, but I’ve fortunately never had a bricked battery. It’s kind of a last resort, but it beats buying another 150$ battery. And yes, it worked for my friend.
