I bought a phantom 2 vision last month on amazon and haven't had a problem with it. I always fully charge the battery before taking it off the charger. So anyway today I plug in the battery and I didnt do the press once then press and hold 2 seconds to turn it on it just automatically came on and on my iPad I was getting a "invalid battery" message. So I took it out, blew on the probe things plugged it back in and the invalid battery message was gone. So I fly it about 8 minutes and I smell something burning so I instantly landed it and took the battery out and it was very hot. There doesn't seem to be any damage to the quad, just the battery. I'm certainly not gonna try to fly it again with that battery. So should I contact DJI could I get a replacement battery or should I just heck with it and buy a new battery?
