Phantom batteries are unbelievably poor quality. I have one that was charged 50 times and now wont charge. That means each flight costs me $3.00. It is SN 1277 and displays 4175, 4158, and 4153, 81% of life, and it gets about 5 minutes of flight time. It goes from 60% to less than 30% in less than a minute. I use it for quick testing when I go fly, what a POS! My second battery is at 94% of life and displays 4181, 4188, and 4184, it lasts about 8 minutes, after 19 charges. The third battery is 90% of of life after 30 charges and display 4156, 5154, and 4159. It also gets about 8 minutes of flight time. So $450 spent on batteries and together they dont get the original 25 minutes with never a crash or even a hard landing. I really like DJI's stability and flight performance but just cant afford ~3.00 per flight after spending nearly $2K on the setup. Put it together with poor customer service and especially the fly-aways that are their issue but the owner's problem. Don't think I am ready to purchase and Inspire @ $3200. I, for one, cant wait for the competition. Come on Go Pro!
