The Phantom Vision (V2) will have over 5000 mAh battery. -If your handy, is it possible to mod your V1 to run with V2 batteries? Or would there be other issues with it, other than that it does not fit in and has different connectors? -If you could find let's say 4000mAh battery that would fit the V1 one casing, would there be any issues unknown to noob like me? -Does Phantom Vision have some other features that will make to quad fly longer besides the extended battery-life. So if you would be able to get 5000mAh battery fit into V1, would it still have shorter flight time (if the weight would be same as V2).
