Overview
The SmallRig CB75 Camera Base Battery mounts directly onto the bottom of your camera to keep it powered through handheld shooting, while making it easy to switch across to a tripod setup. Its 20,000mAh, 73.8Wh capacity can run a Canon R5 Mark II for over six hours or a Sony a7 IV for over seven hours when recording 4K video, and an optional HawkLock Arca-Swiss plate adds a one-click mounting system for fast transitions between rigs.
Camera Screw Mount with OLED Display
Two 1/4"-20 camera screws attach the battery directly to the base of your camera, and an OLED screen keeps remaining capacity visible at a glance.
D-Tap, USB-C and DC Barrel Ports
- Two D-Tap I/O ports for powering additional accessories on set.
- Two USB-C I/O ports supporting 65W fast charging for wide device compatibility.
- A DC barrel output for compatible cameras and monitors.
65W Fast Charging
The battery supports 65W fast charging over USB-C and can be fully recharged from empty in around two hours, minimising downtime between shoots.
