Ooh, I forgot to mention...

The "C" rating determines roughly how much current the battery can safely put out. A 2200mAh 20C lipo can handle (2.2Ah x 20C) = 44A continuous current. It's more of a ballpark figure than a solid number, and you're best off just staying well below it.

Either way, running a battery at just 10C constant draw will mean you get 4.8 minutes of runtime. 20C continuous means less than 2.5 minutes. Most power systems never get anywhere near this kind of continuous power, so the only real advantage of a higher C pack is less loaded voltage sag (at the expense of higher cost, usually more weight, and often bigger physical size).
