Help with powering Leonardo

I have been creating a game controller and I was going to install the blue tooth module that I am using and then was thinking about power. I have a 7.2v batter pack that is essentially 6 AA Batteries. Can I use this to power the Leonardo? I don't want to break it;O) BTW the battery pack is rechargeable and came with a wall wort for recharging an airsoft rifle.

If anyone reads this, this method works great!!
