Yep to charge at 1C rate you charge a 2200 lipo at 2.2 amps. And make sure you have the correct cell count!
Don't forget, never leave the lipo alone while it's charging. IF something would happen, it will get real ugly real fast.
Keep asking before you do something if you are not sure. Much easier for us to tell you yes or no and explain why, then to explain why after the fact.
