Okay so the time has come where I need to buy a extra battery. Have seen a lot of aftermarket batteries some look original am not sure. I seen 5400 mah lipo. Supposed to give five minutes extra flight time. It also has a higher C rating. Another type I seen had an LCD at the front! http://www.ebay.co.uk/itm/like/12156702 ... 108&ff19=0 http://www.dx.com/p/5400mah-li-polymer- ... PJQa4GQGK0 Does anybody have any experience with these or similar? Please could you advise me what the best battery is for the best flight Time and performance. Also seeing some charges which can charge multiple batteries at once. Do You guys recommend this?
