You want your battery to be able to provide more amps than the ESC can pull (ideally) So if the speed controller is 30amp and the battery can deliver 35 or 40 your fine because you cant hurt a battery by pullling less than its capacity but you can almost garantee problems by trying to pull 50 amps out of a battery designed to provide 40


Capacity * C /1000 = amps

2200 mah * 25C = 55000 mah /1000 = 55amps Hooked up to a 35 or 40amp esc this would be perfectly happy.
