Orion XS 12/12-50A DC-DC Battery Charger

High-performance DC-DC battery charger. 50A output. 700W. Built-in Bluetooth. Adaptive 4-stage charging for lead-acid and lithium batteries.

Smallest Design, Superior Power

The Orion XS is the most compact, high-power DC-DC charger available, delivering up to 98.5% charging efficiency. Its robust, fanless design stays cool while maintaining full rated output, even in hot, cramped compartments.

Full Rated Power, Even in High Heat

The Orion XS uses a re-engineered aluminium circuit board that also acts as a heat sink, combined with more efficient components to reduce power loss. Its fanless design delivers full output up to 40°C before any thermal derating occurs.

Smart Alternator Compatible

Modern vehicles feature smart ECU-controlled alternators that vary output voltage to reduce fuel consumption and emissions. The Orion XS has an integrated engine shutdown detection mechanism that activates the charger only when the alternator is supplying power, preventing starter battery discharge.

Configurable Voltage and Current

Input current can be precisely limited to prevent alternator overload. Charging voltage is fully configurable to match lithium, AGM, gel, and other battery chemistries. Eight pre-programmed battery settings are available via the VictronConnect app.

Bluetooth Smart Built-in

Monitor, configure, and update your charger via the free VictronConnect app. Any Bluetooth-enabled smartphone or tablet gives you instant access to real-time data, history logs, and advanced settings. Instant Readout displays key data without needing to connect to the product.

Adaptive 4-Stage Charge Algorithm

Features bulk, absorption, float, and storage charging stages. For lead-acid batteries, absorption time is kept short during shallow discharges to prevent overcharging, and automatically increased after deep discharge to ensure full recharge. For lithium batteries, absorption time is fixed at 2 hours by default.[

VE.Smart Networking and VE.Direct

VE.Smart Networking allows wireless data sharing with other Victron devices for accurate voltage, temperature, and current compensation. The VE.Direct port enables connection to a GX device for full system integration and remote monitoring via the VRM portal.

Parallel Operation for Higher Output

Need more charging power? Connect multiple Orion XS units in parallel to increase output current for larger battery banks or higher-demand applications. This flexible setup makes it easy to expand charging capacity as demand grows.

SafetyShield+ Protection

Engineered for critical applications, the Orion XS features IP65 water and dust protection, temperature-compensated charging, low-temperature shutdown for lithium batteries, input undervoltage protection, and comprehensive safeguards against overload, short circuits, and overheating.
