I had the battery plugged in for about 30 minutes of flying up and down and then physically moving the copter to a new spot to take off. I was very happy with the results. Having 4-5 of these charged and ready to go should be more than enough for the average shoot. Hell the sorry ass battery on the Sony 5N barely lasts an hour of use anyways.
You get 15 - 18min with a 6S 8000 30C? I have that same battery and setup with not the same result, what are you letting the voltage get down to?
