It is built for professional mobile and off-grid installations where a dedicated, controlled charge source is required between two 12V battery banks.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e50A output current for fast, efficient charging of auxiliary or leisure batteries from a 12V starter battery.\u003c\/li\u003e\n  \u003cli\u003eNon-isolated design delivers high current in a compact, lightweight package weighing just 0.35 kg.\u003c\/li\u003e\n  \u003cli\u003eCompatible with a wide range of battery chemistries including lithium (LiFePO4), AGM, gel and lead-acid.\u003c\/li\u003e\n  \u003cli\u003eAdaptive charge algorithm adjusts to the connected battery type for accurate, safe charging.\u003c\/li\u003e\n  \u003cli\u003eVE.Direct port enables monitoring and configuration via Victron's GX devices or VictronConnect app.\u003c\/li\u003e\n  \u003cli\u003eEngine detection function prevents discharging the starter battery when the alternator is not running.\u003c\/li\u003e\n  \u003cli\u003eSuitable for 12V vehicle, marine and off-grid dual-battery systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion XS 12\/12-50A sits in Victron's non-isolated DC-DC charger range, which means it shares a common ground between input and output. This is the correct choice for most standard vehicle and marine dual-battery installations where both batteries share the same chassis ground. The non-isolated topology allows the unit to deliver a full 50A output in a very compact form factor, making it straightforward to install in tight spaces such as van conversions, motorhomes and narrowboats.\u003c\/p\u003e\n\n\u003cp\u003eAt 50A, this charger can replenish a 100Ah lithium auxiliary battery from near-empty to full in approximately two hours of driving, which is a meaningful improvement over split-charge relays or lower-rated DC-DC units. The engine detection feature monitors input voltage to determine whether the alternator is active, preventing the unit from drawing down the starter battery when the engine is off. This is particularly important in lithium auxiliary battery installations, where the low internal resistance of the battery could otherwise pull the starter battery flat very quickly.\u003c\/p\u003e\n\n\u003cp\u003eVE.Direct connectivity allows the Orion XS to be integrated into a wider Victron system. Charge parameters, battery type and operating mode can be configured using the VictronConnect app over Bluetooth (with an optional dongle) or via a GX device. This makes it straightforward to set up correctly for the specific battery chemistry in use, which is essential when charging lithium batteries that require precise voltage limits.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI121217050\u003c\/li\u003e\n  \u003cli\u003eInput voltage: 12V DC\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 12V DC\u003c\/li\u003e\n  \u003cli\u003eOutput current: 50A\u003c\/li\u003e\n  \u003cli\u003eIsolation: Non-isolated\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.35 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076068501\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVan conversions and campervan builds requiring fast auxiliary battery charging from the vehicle alternator.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and caravan dual-battery systems where a controlled charge source is needed.\u003c\/li\u003e\n  \u003cli\u003eMarine installations with separate starter and service battery banks on a shared ground.\u003c\/li\u003e\n  \u003cli\u003eOff-grid vehicles and expedition rigs with lithium or AGM auxiliary battery banks.\u003c\/li\u003e\n  \u003cli\u003eNarrowboat and canal boat 12V house battery charging from the engine alternator.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVictron Orion XS 12\/12-50A DC-DC battery charger unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis unit is non-isolated and requires a common ground between the input (starter battery) and output (auxiliary battery) circuits. It is not suitable for installations where electrical isolation between the two battery banks is required. Wiring must be appropriately rated for 50A continuous current, with correctly sized fusing on both the input and output cables as close to the battery terminals as practicable. Installation by a qualified auto-electrician or marine electrician is strongly recommended, particularly in lithium battery systems where incorrect voltage settings can cause damage or safety hazards. Ensure the selected charge profile matches the auxiliary battery chemistry before commissioning.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47821449462094,"sku":"ORI121217050","price":253.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-orion-xs-1212-50a-dc-dc-battery-charger-ori121217040-601610.jpg?v=1747944820","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-xs-12-12-50a-dc-dc-charger","provider":"VoltaconSolar","version":"1.0","type":"link"}
