12V Victron Complete Camper Van Electrical System Bundle - Secondary Alternator - "Road Runner"

The 12V Victron Electrical System - Secondary Alternator Bundle is the most capable 12V electrical system we offer — built for vanlifers who live on the road full-time, or have extended stays off-grid, and refuse to compromise on power. This isn't just more battery capacity. It's a fundamentally different class of system — Victron Lithium NG batteries with an external BMS, a dedicated high-output secondary alternator, and the full Cerbo GX ecosystem networked together into one intelligent, self-managing power system. Drive for a few hours and your 900Ah battery bank is substantially recharged. Park for a few days and the system manages itself.

🔧 Wiring, terminals, and fuses included — we've already sized and spec'd every component, wire, terminal connector, and fuse to work together for your exact configuration. No spreadsheets, no wasted time, no guesswork — skip the headache.

💰 Pay for what you need, nothing more — wire and terminals are typically sold in bulk, leaving you with an expensive pile of leftovers you'll never use. Every Road Runner bundle includes exactly what your install requires, plus a few spares for peace of mind.

Features:

• Battery capacity: 900Ah (12V)
• Inverter/Charger: 2400W continuous, 5500W surge
• Alternator charging: 120-220A+
• Shore power: 30A (up to ~3,600W)
• Monitoring: Cerbo GX + 7" GX Touch 70 touchscreen + VRM remote portal

Beyond the Hardware

• ⚙️ Every component is firmware-updated and pre-configured before it ships — all Victron devices and the Wakespeed WS500 are set up to communicate with each other right out of the box, so you're not starting from scratch with factory defaults
• 📋 Comprehensive wiring and connector diagram included for install guidance — laminated, large format
• 🛠️ Questions during your install? Vanlife Outfitters' expert support team has you covered — reach out anytime

Who Is This For?

The "Road Runner" is built for the vanlifer who lives in their van full-time or takes extended off-grid trips where power is never an afterthought. It's a great fit if you:

• Live in your van full-time and need a system that keeps up with daily power demands indefinitely
• Want the fastest possible battery recharge while driving — the secondary alternator delivers 120-220+ amps directly to your battery bank, dwarfing what a DC-DC charger alone can provide
• Run heavy appliances daily — induction cooktop, hair tools, power tools, large monitors — without rationing power
• Want a system where every component talks to every other component — the Cerbo GX networks your inverter, BMS, alternator regulator, and more into a single unified dashboard
• Are ready to step up to Victron's premium Lithium NG battery platform with an external BMS for maximum performance, safety, and control
• Want remote monitoring via the VRM portal so you can check your system from anywhere
• Plan to add solar and want a system that's built to integrate it seamlessly
• Want the ability to expand and add a fourth battery down the line — the external BMS setup makes it straightforward. 

What Can It Do?

With 900Ah of Victron Lithium NG power, a 3000W inverter, and a dedicated high-output secondary alternator, the Road Runner handles full-time van life without breaking a sweat:

• 🔋 Maintain a full battery bank on driving days — the secondary alternator delivers 120-220+ amps while you drive, recharging your batteries far faster than any DC-DC charger
• 🍳 Cook on an induction cooktop, run a microwave, and power the rest of your van simultaneously without breaking a sweat
• 💻 Power a full mobile office — multiple monitors, laptops, hard drives, and all your devices, all day
• 🌡️ Run a rooftop air conditioner for extended periods — pair with solar for truly indefinite use
• 📊 Monitor everything from one 7" touchscreen — battery state, inverter load, alternator output, and more, all networked through the Cerbo GX
• 🌐 Check your system remotely via Victron's VRM portal — see your power status from anywhere in the world
• 😴 Run every comfort appliance overnight — fans, lighting, CPAP, phone charging — without thinking twice
• 🔌 Plug into shore power with full surge protection when it's available, and let the MultiPlus handle the switchover automatically

What it won't do: run a rooftop air conditioner indefinitely without using shore power or turning on your engine to take advantage of the massive recharging power of your secondary alternator — even 900Ah has limits against a sustained high draw.

Adding a Sun Seeker solar bundle completes the picture and gives you a true four-source charging system: secondary alternator, solar, shore power, and your vehicle's primary alternator.

How Does It Compare to the Pro Bundle?

The biggest leap from the "Trail Blazer" to the Road Runner isn't battery capacity — it's the entire charging and battery architecture. The Trail Blazer uses SOK lithium batteries with an internal BMS and two DC-DC chargers for alternator charging. The Road Runner replaces all of that with Victron's premium Lithium NG batteries managed by the Lynx Smart BMS NG for closed-loop system control, and a dedicated secondary alternator that delivers up to 220+ amps while you drive — compared to 100A from two DC-DC chargers. The result is a system that recharges dramatically faster on driving days, gives the Cerbo GX complete visibility and control over every charging source, and steps up to a 7" GX Touch 70 touchscreen for a bigger, clearer dashboard. If the Trail Blazer is a serious build, the Road Runner is a full-time home.

Why a Secondary Alternator?

A DC-DC charger is a great starting point for alternator charging — but it maxes out at 50-100 amps. The Nations secondary alternator paired with the Wakespeed WS500 Pro regulator is in a different league entirely — think of it as a powerful generator that runs off your engine every time you drive. For maximum recharging power, this system includes both a DC-DC charger for your stock alternator and a dedicated secondary alternator!

• DC-DC charger alone: 50-100A into your battery while driving
• Secondary alternator: 120-220+ amps into your battery while driving

The Wakespeed WS500 Pro is what makes this safe and intelligent. It's the only alternator regulator that uses current, voltage, and temperature simultaneously to deliver precise, battery-friendly charging — and it communicates directly with the Cerbo GX via CAN bus so alternator output is visible right on your dashboard alongside everything else.

Why Victron Lithium NG Batteries With an External BMS?

This bundle uses Victron's premium Lithium NG batteries paired with the Lynx Smart BMS NG — a fundamentally different architecture than the SOK batteries with internal BMS used in our other bundles. Here's why it matters:

• Higher continuous discharge rates — Victron Lithium NG batteries support significantly higher continuous discharge, meaning fewer batteries are needed to support heavy inverter loads.
• Closed-loop BMS control — the Lynx Smart BMS NG communicates directly with your inverter, DC-DC charger, and MPPT via the Cerbo GX, automatically managing charge and discharge to keep your batteries healthy without any manual intervention
• Built-in 1000A safety contactor — acts as a secondary safety mechanism that can disconnect the entire system if the BMS detects a fault, and doubles as a remote-controllable main system switch
• Pre-alarm warnings — the BMS provides advance warning before any shutdown due to low cell voltage, so you're never caught off guard
• Full Cerbo GX integration — battery state, fuse monitoring, and BMS status are all visible on your GX Touch 70 and remotely via the VRM portal

Wiring, Lugs, Heat Shrink, Ring Terminals, Ferrules

This is the big one — we understand how frustrating it is to buy all of your main system components and then be left to research and separately purchase the dozens of little parts and pieces you need to put it all together. We include everything needed for a complete install, including all wire and terminal connectors, sized to your system's components. We only source high-quality parts, including Ancor wire and terminals.

What's Not Included:

• Tools — crimpers, wire strippers, a drill, etc.
• Solar - We think DC-DC (alternator charging) and shore power are the best, and most powerful options to start with. Adding solar charging is largely dependent on available rooftop space. Check out our roof top solar bundles here!
• 120V Branch Circuit Breakers and 12V Blade Fuses for your WFCO AC/DC Load Center. A main 50 amp breaker is included, but breakers for your 120V branch circuits are not.
