dodgemcopter,
The battery stuff can be confusing, but it's not that tough to understand. For this size heli a three cell (11.1V) Lipo is what you want. Lipo batteries are made up of cells of 3.7V each. A two cell works great in the #4. The 800, 1100, 1200, etc. denotes the capacity in milliamp-hours (mAh). An 800mAh battery can supply 800mA for one hour, or 400mA for two hours, or 1600ma (1.6 Amps) for half an hour, etc. Capacity equates to flying time. The 10C, 12C, etc. denotes the whammo! You have to combine the "C" rating with the capacity to get the maximum amount of current the battery can supply. So an 800mAh 10C battery can supply a maximum of 10x800mA or 8000mA (8 Amps). An 800mAh 12C battery can supply 12x800mA or 9.6 Amps. Sometimes you'll see two C ratings given for a battey - continuous and burst. The continuous rating is what it can supply, well, continuously. The burst rating is what it can supply for a second or two.
A couple of things to keep in mind is that weight is an important factor with anything that flies. A 2000mAh battery won't give you twice as much flying time as a 1000mAh battery because it's probably twice as heavy. You reach a point where the helicopter won't even be able to lift the battery. It's also been reported here that high C batteries tend to burn up motors and ESCs. That extra whammo can do some damage.
So the answer to your question is that something in the 1000mAh area, 10C to 15C will work just great in the 22E.
Hope this helps!
