The recently released SmallRig CB75 is a base-mounted battery solution developed for mirrorless and cinema camera users seeking a compact, integrated power source. Unlike traditional V-mount or Gold mount systems, which often require adapter plates and add bulk to camera rigs, the CB75 is designed to attach directly beneath the camera body using standard 1/4″-20 mounting points, enabling it to function as both a battery and structural baseplate hence reducing the number of components in a setup.

With a capacity of 20,000mAh (73.8Wh), the CB75 can deliver extended power suitable for long-form video recording: according to internal figures, it can supply power to a Canon R5 Mark II for over six hours or a Sony a7 IV for more than seven hours during 4K video capture. It is equipped with two D-Tap ports, two USB-C ports and one DC barrel output, allowing simultaneous connection to a variety of devices including monitors, LED lights, smartphones and laptops. The USB-C ports support fast charging at up to 65W and the battery itself can be fully recharged in approximately two hours using a standard USB-C charger.
