I heard that there's an official Microsoft rechargeable battery pack that can be used with the Play and Charge Kit, and another one that's only a "shell" battery compartment that you attach to your controller and use normal disposable batteries for it. Which kind of battery pack is included when you buy an Xbox 360 Wireless Controller?
