The Power Base is a holder for your EZ-B v4 Smart Robot Controller. It lets you use your EZ-B v4 outside of a robot body.
The Power Base contains a 20 amp fuse and barrel jack, which supplies power. Like the bodies of all Revolution robots, the size of the shell was designed to enhance the audio of the ez-bv4's internal speaker.
Connect an Alternate LiPo Power Adapter and 6xAA Battery Holder to provide power to the Power Base.
