You want about 6000mAh atleast, to get enought flight time, and a low enough avarage discharge of the cells. if you like full throttle flying a lot a C50XL or AXI 53XX can not handle the 3kW, then you need a larger motor and larger pack.
if you use the throttle properly the "3kW burst" motors would work fine on a 10s2p pack
