The Canon BG-E11 Battery Grip is an optional battery grip with improved ergonomics designed specifically for the Canon EOS 5D Mark III, 5DS, and 5DS R. It allows users to load a choice of one or two LP-E6 battery packs. With two packs, the already-impressive battery life is doubled, compared to using a single LP-E6 pack in-camera. This is especially useful when taking advantage of the camera's movie mode or Live View mode - operating modes that use more power.
