The Victron Orion XS 12/12-50A is a non-isolated DC-DC battery charger built for 12V to 12V charging in vehicles, boats and off-grid systems. It supplies up to 50A of charge current, a useful step up for dual-battery setups and larger lithium banks that need faster replenishment.

Victron Orion XS 12/12-50A key features

• Charge current, up to 50A from a 12V source to a 12V battery bank.
• Isolation, non-isolated, for shared-negative electrical systems.
• Battery compatibility, lead-acid (AGM, gel, flooded) and lithium (LiFePO4).
• Weight, 0.35 kg.
• Monitoring, VE.Direct port, configurable via the VictronConnect app.
• Charge algorithm, adaptive bulk, absorption and float stages.

Product overview

The Orion XS 12/12-50A sits within Victron's non-isolated DC-DC converter range. Non-isolated units share a common ground between input and output, which suits most vehicles and boats where the chassis or hull acts as the negative return.

Setup runs through the VictronConnect app over Bluetooth, or via the VE.Direct port for wired monitoring. Charge profiles can be matched to the connected battery chemistry, with the unit managing absorption and float voltage automatically once configured.

Applications

• Dual-battery systems in campervans, motorhomes and caravans.
• Marine auxiliary battery charging from a starter battery or alternator feed.
• Off-grid vehicles and expedition builds needing high-current secondary charging.
• Lithium battery bank charging in 12V mobile and marine systems.
• Commercial vehicle auxiliary power installations.

Installation notes

This is a non-isolated charger and needs a shared negative between input and output circuits. Installation should be carried out by a qualified auto-electrician or marine electrician, with correct cable sizing and fusing on both sides given the 50A operating current. For lithium installations, check that the battery's BMS is compatible with the charger's settings before commissioning.
