Victron Energy ORI121221040 Orion XS 12/12-70A DC-DC Battery Charger

High-Power, Ultra-Efficient DC-DC Charging for Advanced Dual Battery Systems
The Victron Orion XS 12/12-70A (ORI121221040) is a next-generation DC-DC battery charger designed to deliver fast, controlled, and highly efficient charging between 12V battery systems. Built for modern vehicles with smart alternators, it provides a reliable way to charge auxiliary or house batteries from the starter battery while protecting the electrical system.

Engineered for demanding applications in RVs, camper vans, boats, and commercial vehicles, the Orion XS combines high output power with an ultra-compact, fanless design. It is capable of delivering up to 70A (1000W) of charging power while maintaining high efficiency and stable thermal performance even in confined installations.

With full integration into the Victron ecosystem, the Orion XS can be configured and monitored via Bluetooth using the VictronConnect app, giving complete control over charging profiles, current limits, and system behavior. It is suitable for lithium, AGM, gel, and lead-acid battery systems.
