Building out a mobile production rig is a constant battle against space. Every single inch counts. I spent weeks staring at the layout of my camper van conversion trying to figure out how to maximize power without losing valuable floor space. The solution? A custom, multi-functional electrical setup.The wiring process was difficult, but I finally got the 12-volt lithium battery fully powered. I mounted the heavy-duty unit inside the custom bench frame, allowing it to tuck completely away inside the base of the wood structure. The result? Incredible. With everything safely routed, the hidden system sits out of sight, giving us full access to electricity while maintaining a clean walkway.The functionality does not stop at the battery box. I wired the connections up to a series of wall outlets, including integrated USB ports for camera gear. The system powers everything. It sends juice directly to the overhead lighting and the ceiling fan, meaning we can run our equipment and stay comfortable without any messy cords exposed in the main cabin.AdvertisementAdvertisementEvery component in a small-scale build needs to serve more than one purpose. By integrating the power hub and structural seating into a single area, the build remains clean and functional. If you are planning your own layout, always look for ways to make your hardware do double duty.
