The Victron Orion-Tr Smart 12/12-30A Isolated DC-DC Charger delivers a full 360W of regulated charging power to your auxiliary battery — intelligently and in complete electrical isolation from the vehicle's starter battery. Built around Victron's adaptive 7-stage charging algorithm, it communicates directly with compatible Victron lithium and AGM batteries via Bluetooth and the VictronConnect app, automatically adjusting charge profiles to suit lithium (LiFePO4), AGM, gel, or flooded battery chemistries. The galvanic isolation eliminates ground-loop interference and protects sensitive electronics, making it equally at home in a 12V caravan, RV, or 4WD dual-battery setup where clean, reliable power transfer is non-negotiable.

Designed for the demands of Australian touring — long dusty corrugations, remote outback runs, and extended off-grid stays — the Orion-Tr Smart 12/12-30A is the go-to DC-DC charger for caravanners and 4WD adventurers who need their house battery kept at peak charge from the alternator, without risking damage to modern smart-alternator vehicles. Its engine-detection feature prevents discharge of the starter battery when the motor is off, while synchronised parallel operation lets you stack two units for up to 60A of combined output. Whether you're powering a fridge, inverter, or lighting rig deep in the bush, this charger keeps your auxiliary bank healthy and ready for whatever the road throws at you.
