I have a few battery related questions. I need to pickup a battery for a hexacopter using the 880Kv motors. I want a battery solution that provides maximum flight time. Arducopter's battery specs recommend 2200mAh 3S 20-30C, or 2650mAh 3S 20-30C.
1) Would it be possible to use a LiPo 11,000 6-cell 22.2v Battery Pack?
2) Would using another battery pack such as the LiPo 11,000 6-cell 22.2v Battery Pack require modification to the ArduCopter software beyond weight adjustments? Are there voltage configs that need to be changed in the software for RPM? Would added hardware be needed to limit voltage output of the battery?
3) Is there a point where weight counteracts capacity? Anyone have any good idea where that is with the goal of maximum flight time?
This guy was able to get slightly over an hour flight time! :)
If there's already a thread or doc out there that covers these questions, please link :) I've read a few good posts already. Thanks

You cannot use 6s lipos. Even 4s could be a little too much for those motors.
Regarding the video you should pay attention to the specs:
2 x 11000 4s batteries @ 820g each!
14x4" props
and 530kV motors.....
there is almost 1.7Kg only of batteries...
And yes flight time decreases with weight, so it is a matter of finding the best flight time to weight ratio. In some situations a 4500 mA 3s will be only a few minutes more than a 2200 mA.
If you are using standard 3DR or JDrones ESCs and motors, you can't use a 6-cell battery pack. The voltage would be out of specs. Use 3 cells or 4 cells battery packs only.
Or this?
