How to Wire Van Batteries for a 12V System (Shunt, Bus Bars & Fuses)⚡🤯🔧🧠

In this video, I show you how I wired the 12V electrical system in my van, including the batteries, MRBF fuse, shunt, bus bars, inverter, and battery disconnect switch.⚡ Electrical is not my favorite part of a van build, and this was one of the most challenging steps for me. I watched countless videos, read a lot, and moved slowly because safety matters when you’re working with batteries and high current systems. This video is for anyone who feels unsure or overwhelmed by van electrical — you’re not alone.🤯 You can do it! I cover: Wiring batteries in parallel (red to red, black to black) Installing an MRBF terminal fuse Why and where to install a battery shunt Making custom cables (cutting, crimping, lugs, heat shrink/tape) Installing positive and negative bus bars Connecting the inverter and on/off switch How I think through cable routing and component placement I’m not an electrician — just a DIY van builder learning carefully and sharing what worked for me. 🔧 Products Used : ⚡Battery shunt & monitor (Victron): https://amzn.to/49Uk3Jl ⚡ MRBF terminal fuse & holder: https://amzn.to/4aa8DSO ⚡Positive & negative bus bars: https://amzn.to/3YWbQzg ⚡Battery disconnect switch: https://amzn.to/3YWbU1Y ⚡Hydraulic crimping tool: https://amzn.to/3YWc4q6 ⚡2 AWG battery cable: https://amzn.to/45w6iiC ⚡5/16″ & 3/8″ lugs: https://amzn.to/4sXMONP https://amzn.to/4bOyZuU ⚡ Inverter: https://amzn.to/49XwWCo ⚡ Inverter/Charger: https://amzn.to/4pRQfD7 Note - Some links may be affiliate links — thank you for supporting the channel! 🎥 Related Van Build Videos Installing Rear Windows in a Sprinter Van (step-by-step):    • How to Install Rear Windows in a Mercedes ...   Installing a Midi Heki Skylight:    • Installing a Dometic Midi Heki Skylight in...   Solar Install (Part 1):    • Installing Solar Panels on a Sprinter Van ...   Solar Install (Part 2):    • Sprinter Van Solar Install | Final Wiring,...   🙏Thanks for watching — and take your time with electrical.
