I found a deal online for a Phantom 2 and needed some advice on whether to buy the drone or not. The owner says that it flies, but that the battery has reached a 95% critical battery life so the drone will only fly for a few minutes before returning home. He says that all it needs is a new battery and it will be good as new. I'm not sure if this is something legit that happens to the Phantom batteries or if it could be a bigger problem with the drone itself. Here's a screenshot that he sent of the battery info from the software. Thanks for any help you can give! He's selling it for $500 with the Go Pro 3 gimbal.
