Short Summary

The Victron Orion-Tr Smart 12/12-18A Isolated DC-DC Charger is a galvanically isolated DC-DC (B2B) charger that charges a 12V auxiliary battery from the starter battery/alternator while driving. With 18A output, full isolation, and built-in Bluetooth, it suits more complex 4x4, caravan, and camper dual-battery electrical systems.

Why This Product

Building a reliable 12V power system is about more than just a battery — it's about charging it correctly, monitoring it accurately, and trusting it when you're off-grid. Cheap, unmonitored charging is the quickest way to ruin an expensive battery and end up without power when you need it most.

Victron Energy is the benchmark for off-grid and mobile power, and the Orion-Tr Smart 12/12-18A Isolated DC-DC Charger brings that quality to your build with smart, app-connected control and a proven charge approach. At 4Matt Campers in Cape Town, we help clients put together complete, properly matched 12V systems — so your power works the way it should in real South African conditions.

Key Features

18A isolated DC-DC charge current – Charges a 12V auxiliary battery from the starter battery/alternator with full galvanic isolation.
Galvanically isolated – Isolation helps prevent ground-loop and earth-difference issues in more complex installs.
Built-in Bluetooth – Set up and monitor the charger from your phone with VictronConnect.
Adaptive multi-stage charging – Smart charge algorithm helps protect battery health and extend life.
Engine-running detection – Charges only when suitable to help protect your vehicle's starter battery.
Lithium and lead-acid compatible – Works with AGM, gel, flooded, and LiFePO4 batteries via selectable presets.
Rugged, reliable build – Designed for demanding mobile and off-grid 12V systems.

Ideal For

4x4, bakkie canopy, caravan, and camper dual-battery (B2B) systems
Charging an auxiliary/house battery from the alternator while driving
Builds running lithium (LiFePO4) auxiliary batteries
Clients wanting reliable, app-configurable charging on the move
Dual-battery and off-grid builds across Cape Town, Western Cape, and South African off-grid, camping, and overlanding builds
