Charge your leisure battery properly from your alternator. The Victron Orion-Tr Smart 12/12-30A is a DC-DC charger with built-in Bluetooth — it delivers correct 3-stage adaptive charging to your service battery whether you run lithium or lead-acid, and it’s fully compatible with modern smart alternators.

Benefits:

• 3-stage adaptive charging — bulk, absorption, float — correct for any battery type

• Built-in Bluetooth — monitor and configure from the VictronConnect app

• Smart alternator compatible — won’t overload variable-voltage alternators in modern vehicles

• Engine running detection — automatically starts and stops charging with ignition

• Lithium and lead-acid compatible

• Remote on/off connection available

• Full rated 30A output up to 40°C, operates up to 55°C

Features:

The Orion-Tr Smart 12/12-30A draws power from your vehicle’s starter battery (via the alternator when running) and uses DC-DC conversion to deliver a proper 3-stage charge to your leisure battery. This is critical for lithium batteries, which require precise charge profiles and can be damaged by a raw alternator connection. Built-in Bluetooth means the unit is fully configurable and monitorable from the VictronConnect app without touching the unit. Engine running detection monitors input voltage to automatically start charging when the alternator is producing power. Multiple units can be connected in parallel for up to 400W total output. Dimensions: 130×186×70mm. Download the manual below for full wiring diagrams and configuration guidance.

People are asking

Why do I need a DC-DC charger instead of a battery isolator?

A simple isolator passes voltage directly from the alternator, which can damage lithium batteries and overwork smart alternators. The Orion-Tr Smart uses 3-stage adaptive charging to charge your leisure battery correctly regardless of input voltage, protecting both the battery and the vehicle’s electrical system.

Does it work with smart alternators in modern vehicles?

Yes — the Orion-Tr Smart is specifically designed for smart/variable-voltage alternators found in modern European vehicles. It isolates the leisure battery circuit so the alternator is not overloaded.

What’s the difference between isolated and non-isolated?

Non-isolated (this unit) shares a common ground between input and output — fine for most van builds where both batteries share the vehicle chassis ground. Isolated versions have completely separate circuits and are used where electrical separation is required, such as in some marine applications.

Does it work with lithium leisure batteries?

Yes — the Orion-Tr Smart supports both lithium (LiFePO4) and all lead-acid battery types. Set the correct charge profile via the VictronConnect app.

How does engine running detection work?

The Orion-Tr Smart detects when the engine is running by monitoring the input voltage. When voltage rises above a set threshold (indicating alternator output), it automatically starts charging. When the engine stops, it stops — preventing the leisure battery from being drained back into the starter battery.
