It supplies up to 30A of charge current, delivering up to 360W from a 12V source battery, and is configured over Bluetooth using the VictronConnect app. It suits van conversions, motorhomes, narrowboats and off-grid mobile setups.\u003c\/p\u003e\u003ch2\u003eKey features of this DC to DC battery charger\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e: up to 30A at 12V, giving up to 360W of charging power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth control\u003c\/strong\u003e: built-in Bluetooth with VictronConnect app for setup, monitoring and firmware updates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-isolated design\u003c\/strong\u003e: shared negative between input and output, simplifying wiring where both batteries sit on one chassis ground.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery profiles\u003c\/strong\u003e: adaptive charge algorithm with selectable profiles for lithium (LiFePO4), AGM, gel and flooded lead-acid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine detection\u003c\/strong\u003e: senses alternator voltage so the starter battery is not drawn down when the engine is off.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMS integration\u003c\/strong\u003e: two-wire BMS connection lets a compatible Victron lithium battery or BMS halt charging on command.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow it works\u003c\/h2\u003e\u003cp\u003eThe Orion-Tr Smart non-isolated range uses a synchronous buck converter. Sharing a common negative between input and output makes it suited to installations where both battery banks sit within the same chassis ground, the usual arrangement in road vehicles and inland waterway craft. Configuration runs entirely through VictronConnect over Bluetooth, where charge voltage, absorption time, float voltage and tail current are set to match the service battery chemistry. For lithium service batteries the two-wire BMS port lets the BMS tell the charger to stop when the battery is full or a cell protection event occurs. Engine detection works from an input voltage threshold, so charging only starts once the alternator raises bus voltage above a configurable level.\u003c\/p\u003e\u003cp\u003eThe unit weighs 1.8kg and has a compact footprint, so it can be mounted in an engine bay, under a seat or in a battery compartment.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVan conversions and campervan builds charging a lithium or lead-acid service battery from the alternator.\u003c\/li\u003e\n\u003cli\u003eMotorhomes needing split charging between starter and leisure battery banks.\u003c\/li\u003e\n\u003cli\u003eNarrowboats and canal boats with 12V single-chassis electrical systems.\u003c\/li\u003e\n\u003cli\u003eOff-grid trailers and expedition vehicles charging a secondary battery from the tow vehicle's alternator.\u003c\/li\u003e\n\u003cli\u003eLight commercial vehicles running auxiliary loads such as refrigeration, tools or communications equipment.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation note\u003c\/h2\u003e\u003cp\u003eThis charger is non-isolated and requires a shared negative between the source and service battery banks.
