Colour: Ignite Orange

Developed for teams running ALEXA 35 and ALEXA 265 on Ronin 2, with heavy lift drones, MotoCrane or U-Crane (Russian Arm) camera systems.

Our popular Ronin 2 to ALEXA 35 power cable although useful, does limit pan rotations and becomes a safety hazard in those use cases.

This lightweight battery solution enables teams to use their existing fleet of TB51 batteries, deliver reliable high-voltage to ALEXA 35 / 265, and maintain full pan and tilt control.

Also useful for those looking for a cost effective, compact handheld and tripod rig!

CNC machined from high grade 6061-T651 aluminium. Built to withstand life on set!

Designed and manufactured in Tasmania, Australia.
