Quadcopters UK emailed me this morning. Looks like Santa has dropped off another load of Phantom Vision batteries so I have grabbed myself a couple. Its going to be good going out with more than one battery now. Does anyone have any tips on charging these things in the field. I may try using my old inverter that plugs into the 12v supply in the car. Not to knowlegable with electrics though. Is it likely to do any damage or be able to take the load ? It runs a laptop ok.
