Hi,
I want to assembly my own quadcopter and I have been seeing which parts are the better for my requirements but I don't know which battery I should use. I have seen the next

http://www.hobbyking.com/hobbyking/store/__10306__Turnigy_5000mAh_3S_40C_Lipo_Pack.html
which one do you recommend me to buy and why?
I have thought to buy the motors and ESC:
Motor AC2836-358, 880Kv
ESC 30 Amp
Thanks for help me.

In my opinion and what I've done. I feel the higher C rating batteries do better in multi copters..
My experience is around my Hexa. I used the "large" motors from 3dr with a 25-50 Turnigy Nano 6k and 25 amp esc's..
After 20 or so filghts the batteries began puffing a bit..
I switched to 45-90c Turnigy Nano 5k's and they have been fine for many flights..
I feel using the lower C rating and more motors causes the battery to drain faster than intended. as more motors is higher Amps load.
The battery with the higher C will be expecting you to put a higher load on it and handle accordingly..
Actually I would stay as far as possible from Turnigy batteries. Their quality is going up and down. In last 12 months we blew 7 big packs without any reason and after that we stopped to use them. Try to get something better than those. GE, Hyperion, Tigers etc are better choices than Turnigy.
Weight of the copter and weight of the battery.
Somewhere there is a trade-off. Increasing the size of the battery will not significantly increase the amount of flight time.
I have two quads and use 5000mah batteries for now but I'm just learning how to fly.
