Hi Guy's, a little queerie I have regarding a couple of my battery's. I went out after work today to have a little play and get some video etc, I installed my first battery which I was sure was fully charged a day or two ago....I lift off and within about 30 seconds or so, the Red light was flashing so I started to bring her down and it was fairly obvious the power was pretty much out as she came down hard and fast. I checked her over and all seemed o.k bar a couple of little scrapes on the props. So I installed another battery and got her up and the same thing happened again after about 30 seconds or so. Once again checked her over and all seemed o.k bar another scrape or two on the props. So I installed battery 3 and eventually I get my little time in the air. So I was puzzled on the way home thinking...."I'm sure those battery's were charged"....so indoors I go and put the first battery on charge and within a minute or two the charging light was green, so I swap over to battery 2 and the same again, within a minute or two the green charge light is on ?? On with battery 3 and all was normal....the battery had been depleted after my flight earlier today and was charging. Has this sort of thing happened to any of you guy's or can anyone explain why a seemingly full battery or the Phantom would react like that ? Best Wishes.
