Hi, for my FPV setup I've bought this battery that I use to power the monitor and the RX. http://www.ebay.co.uk/itm/Turnigy-N...Battery-Pack-RC-Plane-Heli-Car-/230957381350? I assumed that I could charge this battery using the DJI balanced charger, but nothing happens when I plug it in. The two batteries I use for flying the Phantom works fine (they are bigger), but this small one doesn't charge. It is a 11,1V 3S battery, so to me it should function just like the other batteries? Why doesn't this one charge?
