I purchased a Phantom 2+ Vision in the summer of 2014. I flew the crap out of that thing that summer and then put it away for the winter - and haven't flown it since. Back when I was flying it there were many Firmware releases that gave people all sorts of trouble. I never updated my firmware because I wasn't having any issues. Now over a year later I want to fly my Phantom and I'm sure I will need a new battery. Will I need to update my firmware to use a new battery or can I simply charge the battery and use it? I know thee have been may updates to the software since I last flew and it seems as each release has its issues. I'd rather keep what I have because I know its reliable. Is there a way to use a new battery without a software change or should I just update the Phantom and not worry?
