Victron Orion battery to battery chargers

The Victron Orion XS 50A DC-DC charger (sometimes referred to as a battery to battery or 'B2B' charger) intelligently and safely charges your leisure batteries from your vehicle's starter battery whilst driving. As modern vehicles use smart alternators, the option of using a basic VSR is not viable in any vehicle with a Euro 5 or Euro 6 engine.

Additionally, the Orion XS B2B is simple to install and simply requires access to the vehicle's starter battery. It charges the leisure battery at a rate of 50A/hr.

Smart functionality

Victron battery to battery chargers have built-in Bluetooth, allowing you to connect wirelessly to the VictronConnect App, which can be downloaded from the app store on Android or iOS devices. The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch and has an engine running detection mechanism.

DC-DC charger - use cases

It is not possible to use a basic VSR in any vehicle which has a smart alternator (Euro 5 and above) or a system with a lithium leisure battery. Instead, use a battery to battery charger in these instances. B2B chargers safely charge your leisure battery to 100% by entering the 'absorption' phase, which VSRs aren't able to do.

For use in dual battery systems in vehicles or on boats where the (smart) alternator and the start battery are used to charge the service battery.

Use the Orion XS charger for both lead acid and lithium batteries. Models are available up to 400W and connect unlimited multiple units in parallel to increase output power.

Suitable for high temperatures up to 55°C with a full rated output up to 40°C.
