I just got a Sky Viper V2450 GPS and would like to get a few more batteries for it. I have looked over eBay and Amazon and none of the sets that come with a charger look like they will work. The connectors look different that what my copter uses. Anyone know where I can find anywhere from a three to five pack that comes with a charger that will work in this specific copter? It uses a 3.7 1200 mHa battery.
