You need to increase the capacity of the battery, this is the mah number, the C is for the rate of charge and discharge. One point to add is that when you increase battery mah the weight also goes up,so the flight times will not double when you double the battery capacity. In short keep an eye on the weight to mah ratios.

I have a standard arducopter setup and with my gopro mounted I get 14 minutes of flight time with a 2650 lipo.

Hey,

Also, as your capacity goes up, you won't need to spend as much money on high C rated packs... As long as your power demand hasn't increased drastically.

ie. 2500mAh x 20C = 50A      where as  5000mAh x 10C = 50A

Don't fall for the 25-40C prices if you don't need it.

Keep that in mind, mmmkay?

Yea I am just going to stick to the same C rate and same cell count and just buy bigger mAH lipos.

Im running a hyperion 35C 3300 mAh 3S and have been getting 20+ mins at 50-60% throttle.IMHO, the more C the better with four + motors .
