I'm a Phantom newbie (have some time on a Syma), flown a handful of times on my P3A with the brand name battery. I purchased a battery on ebay a couple weeks ago and when it arrived I realized it was generic, a 'Gifi Power' battery to be exact. I didn't know that generic Phantom batteries were available so I hadn't thought to check. It doesn't seem to do anything strange when charging or while updating in the drone but I haven't tested it in flight yet. I'm tempted to return it but am not looking forward to the hassle of shipping it back to China. Anyone have experience with this particular manufacturer? Or just generic batteries in particular?
