Canon BG-E6 with Canon LP-E6 Battery Kit
The EG-E6 Battery Grip is dedicated strictly to the EOS 5D Mark II, and permits one or two LP-E6 battery packs to be installed. With two packs, the battery life is doubled, compared to using a single LP-E6 pack in-camera. Especially for extended use of the EOS 5D Mark II’s movie mode or Live View, the BG-E6 is an outstanding accessory. The BG-E6 provides full vertical shooting controls, which can be independently turned on or off as the photographer desires.
