Hi all, I am new around here and new to the RC world. I recently purchased an open box Phantom 2 Vision from a legit seller on ebay. Everything was included and you could tell this thing was never even used. I proceeded to update the firmware and the battery had all 4 lights green and updated no problem. I decided to try the charger out and that is when the issues began. The battery went down to one bar and would not charge at all. I left it on the charger overnight and still nothing... Have you guys ever experienced anything like this? The assistant software said the battery had been charged 2 times I believe... Any help is appreciated, thank you!
