It is suited to marine, vehicle and off-grid applications where independent battery banks must be kept isolated from one another during discharge while still being charged together.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharges two independent battery banks from one input source without cross-discharge between banks.\u003c\/li\u003e\n  \u003cli\u003eFET (Field Effect Transistor) technology eliminates the 0.6V to 0.7V voltage drop associated with traditional diode-based isolators, ensuring batteries receive the full charge voltage.\u003c\/li\u003e\n  \u003cli\u003e100A continuous current rating across both output banks.\u003c\/li\u003e\n  \u003cli\u003eAutomatic operation with no manual switching required during normal use.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.91 kg, suitable for installation in confined spaces.\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard alternators and battery chargers without requiring alternator modification.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eTraditional diode isolators introduce a voltage drop of around 0.6V to 0.7V between the charging source and the battery. Over a charge cycle, this means batteries consistently receive less than the target charge voltage, leading to chronic undercharging. The Argofet 100-2 uses MOSFET technology to eliminate this drop, so the voltage at the battery terminals matches the output of the alternator or charger directly.\u003c\/p\u003e\n\n\u003cp\u003eThe isolator works by allowing current to flow freely from the input to both battery banks during charging, while blocking reverse current flow between the banks. If one battery bank is heavily discharged, it cannot draw down the other bank through the isolator. This makes it particularly useful in dual-bank setups where a starter battery and a service or leisure battery must remain independent during use but be charged from the same source.\u003c\/p\u003e\n\n\u003cp\u003eThe unit requires no external control signal or relay logic for basic operation. It is a passive device in normal use, which keeps installation straightforward and reduces potential points of failure.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ARG100201020\u003c\/li\u003e\n  \u003cli\u003eNumber of battery outputs: 2\u003c\/li\u003e\n  \u003cli\u003eMaximum continuous current: 100A\u003c\/li\u003e\n  \u003cli\u003eTechnology: FET (MOSFET) isolator\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.91 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076019015\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine vessels with separate starter and service battery banks charged from a single alternator.\u003c\/li\u003e\n  \u003cli\u003eCampervans, motorhomes and HGVs requiring split-charge functionality without voltage loss.\u003c\/li\u003e\n  \u003cli\u003eOff-grid systems where a charger must feed two isolated battery banks.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicles with auxiliary power requirements independent of the starter battery.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron Argofet 100-2 FET battery isolator\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 electrician or competent marine\/vehicle electrician familiar with high-current DC systems. Ensure the input and output cabling is rated for at least 100A continuous and that appropriate fusing is fitted on the input side close to the source. The unit should be mounted in a ventilated location as it will generate some heat under sustained high-current operation. Verify compatibility with your alternator output voltage and battery chemistry before installation.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59867185873230,"sku":"ARG100201020","price":72.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ARG100201020_-_Argofet_100-2_Two_batteries_100A.webp?v=1781202034","url":"https:\/\/voltaconsolar.com\/products\/victron-argofet-100-2-fet-battery-isolator-100a","provider":"VoltaconSolar","version":"1.0","type":"link"}
