Agreed. This is what I do. Admittedly I do use full auto too frequently, and I want to change this by getting a trigger master and setting up for 3 round burst only to avoid abuse of full auto. But a nice battery can get you any rate of fire you want, assuming you have a system set up that can handle high speeds (read: high quality internals).
