The Battery Grip for Canon EOS 6D Mark II from Vello is a dedicated power supply that can hold up to two LP-E6 or LP-E6N Li-ion batteries, which doubles the camera's shooting time. Before attaching the rubber non-slip grip, the battery chamber cover of the camera can be safely stored away within the battery grip. Allowing easy access to the vertical shutter release, AF area, AF point selector, AF start, AE lock, and main dial, the grip allows you to control the camera when you're shooting vertically.
