Professional B2B charger installation from £350
Supercharge your off-grid freedom: Professional B2B charger installation in Somerset
Stop relying on outdated split-charge systems. We install high-performance Battery-to-Battery chargers that charge your leisure battery faster, protect your alternator, and are essential for modern lithium setups.
Is your old split-charge system letting you down?
Traditional Voltage Sensing Relays (VSRs) were fine for basic campers, but modern vans and batteries demand much more. If you're still using a basic split-charge relay, you likely aren't getting the most out of your leisure battery — and you might even be damaging it.
Does this sound familiar?
- Your leisure battery barely charges while driving, even after hours on the road.
- Your modern van has a "smart alternator" that varies voltage, confusing your old VSR.
- You've upgraded to lithium but your battery never reaches full charge from driving.
- You worry your basic split-charge setup is damaging your expensive leisure battery.
The way you charge your battery is just as important as the battery itself.
Why B2B charging beats the old split charge
A Battery-to-Battery (B2B) charger is a smart power converter that sits between your vehicle's starter battery and your leisure battery. Unlike a dumb VSR that simply connects them, a B2B charger actively manages the charging process to deliver the exact voltage and current your leisure battery needs.
This matters more than ever with modern vehicles. Today's vans use smart alternators that output varying and often extreme voltages — a B2B charger is the only way to regulate this safely and protect your leisure battery from damage.
B2B chargers also accept higher current for longer, meaning you charge significantly faster while you drive. A short journey can add meaningful charge to your battery, rather than barely making a dent.
Based in Williton, Somerset, we install B2B charging systems for campervans and motorhomes across the county. Whether you're upgrading an existing split-charge setup or building a complete electrical system from scratch, we'll ensure your leisure battery gets the smart charging it needs.
Upgrade to the Victron Orion Smart DC-DC
We recommend and exclusively fit Victron Orion Smart DC-DC chargers for the ultimate setup:

- Built to last — Compact, durable design that maximises your battery's 10+ year lifespan.
The essential step for lithium upgrades
Thinking of switching to lithium? A B2B charger isn't just a recommendation — it's essential.
- Lithium batteries work on different voltages than lead-acid and require a specific smart charging profile that basic VSRs cannot provide.
- Lithium can accept much higher charge currents — a B2B system is the only way to safely deliver that power and reach a full charge quickly.
See our lithium battery upgrade page or complete power package for combined solutions.
Why upgrade to a B2B charging system?
Faster charging while driving
B2B chargers accept higher current for longer, so a short journey puts meaningful power back into your leisure battery — not just a trickle.
Protects your alternator
Smart alternators in modern vans output varying voltages. A B2B charger regulates this, protecting both your vehicle alternator and your leisure battery.
Essential for lithium batteries
LiFePO4 batteries require a specific charging profile that only a B2B charger can provide. Without one, you will never reach a full charge from driving.
Bluetooth Monitoring
Victron Orion Smart chargers connect to your phone via Bluetooth. Monitor charge stages, voltage, and temperature in real-time.
Multi-stage adaptive charging
Automatically selects the correct charging profile for AGM, Gel, or Lithium batteries — no manual configuration needed.
Safe, clean installation
We professionally install and configure every B2B charger with correctly rated fusing, cabling, and ventilation for complete peace of mind.
Our 5-step B2B charger installation process
From first conversation to a fully configured charging system — here's what to expect.
Consultation
Tell us about your van, your current charging setup, and what you're trying to power on the move. We'll advise whether a B2B charger is the right upgrade for your build.
Quote
Within 48 hours we'll send a clear, itemised quote for the correct B2B charger, cabling, and fusing, along with an estimated lead time for any parts we need to order in.
Book the install
A deposit covers the charger and any supporting components, secures stock, and locks in your installation date. Most B2B charger installs are booked in within 2–4 weeks.
Professional fitting
We mount the B2B charger, run appropriately rated cable from the alternator to the leisure battery, and fit the correct fusing at both ends. All connections are torqued and tested to manufacturer spec — typically completed in a single day at our Williton workshop.
Demo and handover
We walk you through the charger's charge stages, connect it to its Bluetooth app, and show you how to monitor performance on the move. You leave with full documentation, our 12-month installation warranty, and ongoing support whenever you need it.
