The DJI Ronin Expansion Base Kit allows you to mount the DJI RS 2 gimbal on a jib, car, slider, cable cam, or other support and control it remotely over 16.4' control cables. The kit features a tethered control handle for extended wired control of gimbal movement plus camera focus, shutter, and other parameters. A base mount and external battery adapter are included for powering the gimbal from its BG30 grip.
