The Victron Energy ORI121221040 Orion XS 12/12-70A is a high-output DC-DC battery charger engineered for dual-battery systems charged from conventional or intelligent alternators. It provides adjustable charging current up to 70A and continuous output power up to 1000W under specified operating conditions. 

Designed for controlled starter-to-service battery charging, the Orion XS combines smart alternator compatibility, adaptive four-stage charging, configurable current limits, Bluetooth Smart, VE.Smart Networking, VE.Direct connectivity, DVCC support, remote on/off functionality, and an adjustable DC power-supply mode. 

Key Technology

• 70A Adjustable DC-DC Charging
  The input and output current setting range extends from 1A to 70A, allowing charging performance to be configured for the connected alternator, battery system, and installation. Charge current can be adjusted through VictronConnect in 0.1A increments. 

• Up to 1000W Continuous Output
  Delivers continuous output power up to 1000W at temperatures up to 40°C under the specified cooling conditions, providing substantial charging capability for higher-demand auxiliary battery systems. 

• 98.5% Maximum Efficiency
  High conversion efficiency helps minimize electrical losses and heat generation during DC-DC charging. 

• Smart Alternator Compatibility
  Integrated engine shutdown detection determines when the alternator is supplying power so charging can be controlled appropriately in systems using conventional or intelligent alternators. 

• Adaptive Four-Stage Charging
  Uses an adaptive charging strategy designed to properly recharge the service battery. The Orion XS includes fully programmable charging algorithms and eight pre-programmed battery settings. 

• Low-Temperature & Input Undervoltage Protection
  Charging can automatically stop at low temperatures to protect lithium batteries, while configurable input-voltage lockout helps prevent excessive discharge of the starter or input battery. 

• Remote On/Off Control
  The charger can be remotely switched through its remote on/off connection or through VictronConnect, supporting integration with external switches and compatible Battery Management Systems. 

• Comprehensive Electronic Protection
  Integrated protection includes overload, short-circuit, and excessive-temperature protection. Output power is reduced when the maximum product temperature is reached. 

• Parallel Operation
  Multiple Orion XS units can be connected in parallel when additional output current is required. 

• Bluetooth Smart & VictronConnect
  Built-in Bluetooth Smart provides wireless configuration, monitoring, and software updates through VictronConnect on compatible devices. Instant Readout can display important operating information, warnings, and alarms directly from the device list.

• VE.Smart Networking
  Supports remote Vsense, Tsense, and Isense information from compatible Victron equipment such as a BMV, SmartShunt, or Smart Battery Sense to optimize charging parameters. 

• VE.Direct & DVCC Integration
  Provides a wired connection to compatible GX devices, computers, and other supported equipment for advanced monitoring, control, diagnostics, and DVCC functionality. 

Best Uses

• High-Current Auxiliary Battery Charging
  Designed for systems requiring controlled charging of a 12V auxiliary or service battery from a 12V starter-battery and alternator system.

• Smart Alternator Vehicles
  Suitable for modern vehicles equipped with intelligent alternators whose output voltage can vary significantly during operation.

• RV & Camper Electrical Systems
  Provides high-output charging for house battery banks while traveling, including installations where cable voltage drop makes controlled DC-DC charging important.

• Marine Dual-Battery Systems
  Well suited to properly installed boat electrical systems where long cable runs and varying alternator voltage can affect service-battery charging.

• Lithium Battery Systems
  Programmable charging, low-temperature shutdown, adjustable current, and BMS control options support properly configured lithium auxiliary battery installations.

• DC Power Supply Applications
  Can operate as a configurable DC power supply when a stable adjustable output is needed instead of a battery-charging cycle.
