It is suited to professional vehicle, marine and off-grid installations where a dedicated, controlled charge source is required for a secondary battery bank.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e70A output current provides a high charge rate suitable for large lithium or AGM service battery banks.\u003c\/li\u003e\n  \u003cli\u003eNon-isolated design allows direct integration into 12V to 12V systems without galvanic separation requirements.\u003c\/li\u003e\n  \u003cli\u003eCompatible with lithium (LiFePO4), AGM, gel and flooded lead-acid battery chemistries on the output side.\u003c\/li\u003e\n  \u003cli\u003eProtects the vehicle alternator by regulating input current draw, reducing the risk of alternator overload.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.379 kg, making it practical for installations with limited space.\u003c\/li\u003e\n  \u003cli\u003ePart of the Victron Orion XS range, which supports configuration and monitoring via the VictronConnect app over Bluetooth.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion XS 12\/12-70A takes power from the vehicle's starter battery circuit and delivers a controlled, algorithm-driven charge to a secondary battery. Unlike a simple voltage-sensitive relay, a DC-DC charger applies a proper multi-stage charge profile, which matters particularly when charging lithium batteries that require precise voltage and current management. At 70A output, this unit can meaningfully charge large battery banks during normal driving cycles.\u003c\/p\u003e\n\n\u003cp\u003eThe non-isolated topology means the input and output share a common ground. This is appropriate for the majority of single-vehicle installations. Where galvanic isolation is required, for example in certain marine applications or dual-battery systems with separate chassis grounds, an isolated variant should be selected instead. Installers should confirm the grounding arrangement before specifying this unit.\u003c\/p\u003e\n\n\u003cp\u003eVictronConnect app support allows charge algorithm selection, input voltage thresholds and other parameters to be configured wirelessly. This removes the need for DIP switches or manual wiring changes during commissioning and simplifies fault-finding in the field.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI121221040\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: 70A\u003c\/li\u003e\n  \u003cli\u003eIsolation: Non-isolated\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.379 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076075257\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharging a 12V lithium or lead-acid leisure battery from a 12V vehicle alternator in campervans and motorhomes.\u003c\/li\u003e\n  \u003cli\u003eSecondary battery charging in commercial vehicles, emergency service vehicles and specialist conversions.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-battery systems where the engine start battery feeds a separate house bank (non-isolated installations).\u003c\/li\u003e\n  \u003cli\u003eOff-grid mobile installations requiring reliable, regulated battery charging from a running engine.\u003c\/li\u003e\n  \u003cli\u003eTruck and HGV auxiliary battery systems where high charge current is needed to recover large battery banks quickly.\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\/12-70A 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\u003eInstallation should be carried out by a qualified auto-electrician or electrical installer with experience in DC vehicle or marine systems. The non-isolated design requires a shared common ground between input and output circuits. Correct cable sizing and fusing at both the input and output is essential given the 70A output rating. For lithium battery installations, confirm that the battery management system (BMS) is compatible with the charge profile applied by the Orion XS. Configuration via VictronConnect requires a Bluetooth-enabled device.
