You can also get new batteries from sellers on Ebay..I have two power edition quads and made the mistake of getting a GiFi 4000mah instead of a Parrot 3350. Yes I got more flight time from the 4000,then the battery disconnected from the drone and it fell 100 feet from the sky and broke the cross frame. I got another couple flights from it,until it disconnected AGAIN 
Turns out that the shell is a P.O.S. and unhooks from the drone. even using a "strap" wouldn't stop it from disconnecting..I now use that GiFi for bench testing or in the SC1 black edition. To quote my parts guy..."never trust your bird to aftermarket parts,especially batteries,since they can cause fly-away's or crashes" I now only use genuine Parrot batteries and parts.
