The Blackmagic Pocket Camera Battery Grip gives you over 2 or 3 hours of non-stop shooting when paired with batteries. Use L Series Batteries Replace the standard LP-E6 Batteries on the BlackMagic Design 4K and 6K Pro Pocket Cameras with 2 L Series Batteries. If you are using this on the 6K Pro you get over 3 hours of shooting time on one charge by adding the option for 2x NP-F570 batteries. Massive Battery Charge with Compact Size The massive battery life will give you more time to record footage and allows more portability. The grip integrates simply with the Blackmagic Pro and retains a compact size. The carbon fibre design has non-slip hand grips allowing for a more comfortable grip, extending the amount of time that you can comfortably use your camera. A slide-out tray makes battery changes easy and a handy battery indicator is visible on the touch screen so you always know how much power you have left. When you are getting low you can even charge the batteries via the 12V DC power connection in camera.
