Canon battery grip BGE14

The BG-E14 Battery Grip is an optional battery grip with improved ergonomics designed specifically for the EOS 70D. 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 battery in-camera. In addition, with the included battery magazine, you can also run the camera off six AA batteries. With a large number of controls, the BG-E14 is ideal for high volume and easy vertical shooting.
