Hi All. I've just received a Phantom 2 and I'm having trouble with my battery. It shows absolutely no sign of life whatsoever. I've tried to power on the battery whilst in and out of the Phantom, before connecting to the charger but nothing. I don't get any lights when connected to the charger despite the charger unit showing it has power. Am I being completely useless or does this sound like I need to get onto the retailer for a replacement? Incredibly frustrating as I can't use it! Thanks in advance.
