Battery Grip for the Canon EOS 6D
The Canon BG-E13 is an optional battery grip specifically dedicated to the EOS 6D. The BG-E13 can be operated with one or two LP-E6 battery packs installed. With two packs, the already-impressive battery life is doubled, compared to using a single LP-E6 pack in-camera.
Alternatively, the grip and camera can be powered using six AA batteries via the supplied holder. For extended use of the EOS 6D's movie mode or Live View, the BG-E13 is an outstanding accessory.
The BG-E13 also provides full vertical shooting controls, which can be independently turned on or off as the photographer desires. Many users find the battery grip can enhance camera handling, especially when shooting vertical pictures.
