The Victron Orion-Tr Smart 12/24-15A Non-Isolated DC-DC Charger delivers up to 360W of power conversion efficiency for dual-battery systems, stepping up from a 12V starter battery to a 24V service bank with intelligent, multi-stage charging. Managed entirely via the VictronConnect app over Bluetooth, this smart charger applies a proper absorption and float cycle to your auxiliary battery — protecting lithium (LiFePO4), AGM, gel, and lead-acid chemistries from the damaging partial-charge that standard vehicle alternators produce. Its non-isolated design is ideal for vehicles with a common negative ground, making installation straightforward without the need for isolation transformers.

Purpose-built for Australian caravanners, 4WD tourers, and RV owners who need reliable on-the-road battery charging, the Orion-Tr Smart shines in dual-battery setups where your house battery must stay fully charged regardless of how long you spend off the beaten track. Whether you're crossing the Simpson Desert, beach camping on the Gibb River Road, or powering up a motorhome between powered sites, this unit ensures your fridges, lighting, and CPAP machines are always backed by a fully conditioned battery bank. The built-in engine-running detection (via a VE.Direct or ignition input) prevents discharge of the starter battery while the engine is off — a critical safeguard for remote Australian travel.
