In this RV DIY project, we install a battery disconnect switch on our camper to stop the battery from draining while the RV sits in storage. If you’ve ever come back to a dead RV battery after a few weeks or months parked, this simple upgrade may save you a major headache.

We walk through the full install process, explain how the disconnect works, show the wiring setup, and even share some of the mistakes and troubleshooting along the way. This isn’t a polished “perfect world” install—it’s real-world RV DIY with limited tools and some improvising on the road.

By the end, we finally have a working battery shutoff system that lets us completely cut power when the RV is stored. And yes… there were definitely a few moments where things didn’t exactly go according to plan.
