Product Details
The Victron Battery to Battery Charger 18A 12/12 Orion-Tr Smart Isolated DC-DC Charger is designed to provide reliable and controlled charging for leisure or service batteries while your vehicle is running. It draws power from the starter battery during driving and delivers a regulated charge to a secondary battery bank, which helps maintain battery performance and prolongs service life. This makes it a suitable choice for vehicle-based electrical systems such as campervans, motorhomes, work vans, and boats where equipment depends on stable 12V power.
This model is well suited to modern vehicles fitted with Euro 5 or Euro 6 engines using smart alternators. These alternators often prevent traditional relay-based charging from operating correctly, which can leave service batteries undercharged. The Orion-Tr Smart solves this by providing a controlled and consistent output regardless of alternator behaviour. With a rated charging current of 18A, it offers dependable daily charging to support lighting, refrigeration, water pumps, communication devices, and similar onboard loads.
Installation is straightforward, requiring access to the starter battery and correct cable routing to the leisure battery. Once installed, the charger requires minimal user input. Built-in Bluetooth adds convenience by connecting to the VictronConnect app on Android or iOS. From the app, users can view live data, adjust charging parameters, and check system status. There is also the option to enable remote control using an external switch, which offers additional flexibility for vehicle layouts.
The Orion-Tr Smart is suitable for both lead acid and lithium batteries, making it a versatile component for mixed vehicle fleets or customer installations. It provides full rated output up to 40 degrees Celsius and remains operational to 55 degrees Celsius, which is important for vehicle engine bays or marine lockers where heat can rise during extended operation. Victron offers compatible models up to 400W, providing scalability for larger off-grid systems or heavier cycling loads.
For trade customers, this charger reduces installation problems, supports faster system commissioning, and improves customer satisfaction by maintaining healthier battery banks. It offers predictable charging behaviour, which reduces the need for return visits.
Overall, the Orion-Tr Smart 18A provides a dependable, modern solution for dual battery systems.
