The Canon BG-E18 Battery Grip is an optional battery grip with improved ergonomics designed specifically for the Canon EOS 750D and 760D. It allows users to load a choice of one or two LP-E17 battery packs. With two packs, the already-impressive battery life is doubled, compared to using a single LP-E17 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.
This BG-E18 battery grip also provides full vertical shooting controls, which enhances camera handling, especially for shooting vertical pictures. This battery grip does not support a battery magazine for AA batteries, or an AC adapter kit.
