So I got my phantom FC40 yesterday and couldn't do anything but charge, as I was stuck working. The included battery charged and went solid green in a bit over an hour but the spare battery that I picked up (which looks exactly like the stock) is still blinking CV mode (and alternating cells) after a total of about 5-6 hours!?!? Is this normal? Charged about 3 -4 hours last night and was too paranoid to leave on the charger overnight. Got up this morning and still charging after 2 hours or so. How long should this "initial" charge take. Been flying micros for a few months now, this is my first "real" quad. :?
