Instructions on Installing a Battery on a Trailer and Wiring it to Run Interior Trailer Lights. Please know that I am not a professional and you should probable consult with one. That said nothing has caught fire in my trailer and everything is running hunky dory at the moment. What you will need is some door bell wire, 30 amp fuse block, maybe some wire nuts and a deep cycle battery. I have a 100 amp hour seal lead acid battery. If you have any questions feel free to reach out to me.
