60A is right at 20C. Usually you can discharge in bursts slightly higher than its constant C rating. The voltage sag at that load will rob you of some power too. It should be flyable with throttle management, but there's not much safety margin in that setup. Personally, I think I'd spend a little more $$ to get either a slightly larger 20C pack (3300-3600mAh) or bump up the C rating. Do it once. Do it right. I've paid quite a lot of "stupid tax" trying to save money on cheap components.
