I bought my first phantom today, and was looking forward to a first flight (beautiful day here in Switzerland), but was unable to. I set a battery charging, connected it all up as per the instructions (manual and the tutorial vid). Everything looked fine and I guess after maybe 40 minutes the charger started blinking between green and red. The manual says that it was now "balancing the cells". Fine I thought, it's meant to take an hour or so. 4 hours later and it's still blinking green and red. So I did some google searching, and saw a suggestion that the battery might be a dud. So I disconnected the battery and connected another one. 4 hours and that battery is doing exactly the same. This video shows what''s happening: http://www.youtube.com/watch?v=CDDNOSPeJIA Not my video, someone else had the same problem I guess. Is this a dud battery charger? Should I buy a new better charger? And can I risk flying my phantom with an 80% charged unbalanced battery? Many thanks in advance for anyone that can help me out.
