I've had my Phantom for a few weeks and everything has been working great. But this afternoon I think I fried my battery charger. I connected my OEM Phantom battery to the alligator clips and then started to insert them in the charger (unplugged from the wall). BUT I screwed up and touched the red clip to the black terminal. When I started to insert the black clip into the red terminal I got a little spark. I backed them both out immediately and corrected the problem. But now the charger will only charge for a few minutes before the charge and 2s light start blinking and then it goes dead and starts again. Guess I am going to by a new charger. Any suggestions?
