Victron Energy Orion XS DC-DC Battery Charger

If your RV has a smart alternator, or you've ever dealt with voltage drop from long cable runs, you already know the problem: your house batteries never quite top off the way they should. The Orion XS fixes that.

Designed for dual battery systems, the Orion XS steps up whatever your alternator is actually delivering and turns it into a precise, controlled charge for your service battery. No more partial charges. No more guessing. And critically, no risk of draining your starter battery in the process.

It automatically detects when your engine is running and only draws power when the alternator is supplying it. When you shut down, it shuts down. Everything works in the background without any input from you.

Smart Alternator Compatible - Engine detection ensures the charger only activates when the alternator is supplying power, protecting your starter battery from discharge
Adjustable Charge Current - Fine-tune output in 0.1A increments via the VictronConnect app
Adaptive 4-Stage Charging - Automatically adjusts absorption time based on depth of discharge, preventing overcharge on shallow cycles and ensuring a full charge after deep ones
8 Pre-Programmed Battery Profiles - Works with lead acid, AGM, gel, and lithium out of the box; fully customizable algorithms available
Low Temperature Shutdown - Automatically cuts off to protect lithium batteries in cold conditions
Input Undervoltage Protection - Shuts down if starter battery voltage drops too low; restarts automatically when voltage recovers
Bluetooth via VictronConnect - Monitor status, adjust settings, and receive alerts from your phone; Instant Readout shows key data without needing to connect
VE.Smart Networking - Pulls live voltage, temperature, and current data from compatible Victron devices (SmartShunt, Smart Battery Sense, BMV) to continuously optimize charging
VE.Direct Port & DVCC - Wired connection to Cerbo GX or Ekrano GX for full system monitoring, remote access via VRM Portal, and BMS control
Parallelable - Connect unlimited units in parallel to increase output current
IP65 Rated - Dust-tight and protected against heavy rain
Comprehensive Protection - Overload, short circuit, and overtemperature protection built in
