The Bower XBGCD7 Battery Grip provides the power you need for the Canon EOS 7D SLR digital camera. It used the power by using 2 LP-E6 rechargeable, high-capacity batteries. In addition, the battery pack provides a vertical shutter release, as well as an AF start button, AF point selection, AE lock/FE lock button, multi function button, and main dial, which all make holding the camera in the vertical orientation as easy and secure as in the horizontal position.
