Default question about ESC and amps

Now how do you know what amp ESC to go with? I have a Scorpion 2215-18 motor and see three different amp speed controllers to choose from. A 25amp, 35amp and 45amp. How do you deciced which is best or the right one? http://www.3dxhobbies.com/Scorpion_ESC_s/95.htm

The max. continuous current draw of the motor is rated at 20amps. You might hit a tad more than that on a burst. You should be fine with the 25amp esc, it will handle a continuous current draw of 25amps, and a bit more on a burst.

Then you need to make sure you chose the right battery pack and prop combination to keep the current below your motor's 20A limit. It's best to get a Wattmeter to check the current draw of your setup. It will more than pay for itself if it keeps you from smoking your battery, ESC, and motor.

OK, I was going to go with the 35amp ESC. so I guess I should be good. I want to use a Thunder Power 1320 or 2100 Mah battery.
