Victron Energy ORI121221040 Battery Chargers
For 12-volt dual-battery systems, delivering adjustable charging up to 70 amps with Bluetooth Smart, VE.Direct, smart alternator compatibility, and programmable charging profiles.
The Victron Orion XS 12/12-70A is a high-performance DC-DC battery charger designed for 12-volt vehicle, marine, RV, and off-grid auxiliary battery systems. It is built for dual-battery installations charged from an intelligent alternator, helping ensure controlled charging of the service battery while protecting the starter battery from discharge.
With adjustable charge current from 1 to 70 amps, programmable charging algorithms, and eight pre-programmed battery settings, the Orion XS 12/12-70 amp supports flexible installation across different battery types and system needs. Built-in Bluetooth Smart allows setup, monitoring, and software updates through the VictronConnect app, while VE.Direct enables wired integration with GX devices for advanced monitoring and control.
This model is especially useful for Euro 5 and Euro 6 vehicles with smart alternators, where alternator voltage can be too low for reliable auxiliary battery charging. Engine shutdown detection activates charging only when alternator power is available.

Check Before Ordering
- Confirm your system is 12-volt input and 12-volt output; this model is not for 24-volt output systems
- Confirm the required charge current is appropriate for your auxiliary battery bank and wiring
- This 12/12-70 amp model is rated IP20 and is intended for dry indoor installation only
- Verify cable size, fuse protection, mounting location, airflow, and installation clearances before installation
- Continuous output power is based on optimal cooling and proper mounting; limited airflow may cause earlier current derating
- Confirm firmware requirements when using DVCC with a GX device
- For lithium battery systems, confirm BMS remote on/off or control requirements before installation
- Use VictronConnect to configure charge settings for the connected battery type
