It automatically combines a starter or auxiliary battery with a lithium house bank during charging, then disconnects when charging stops. Suitable for marine, vehicle and off-grid installations where lithium battery protection is a priority.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRated at 230A continuous current, suitable for high-demand 24V and 48V lithium battery systems.\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled logic monitors battery management system (BMS) signals to allow or block charging.\u003c\/li\u003e\n  \u003cli\u003eAutomatically connects batteries when charge voltage is detected and disconnects when charging ceases.\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for lithium (LiFePO4) battery chemistries, responding correctly to BMS allow-to-charge signals.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.3 kg, suitable for installation in confined spaces.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron BMS products that output a load or charge disconnect signal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-Li-charge relay differs from a standard battery combiner in one important respect: it is designed to work with a lithium BMS. When the BMS signals that charging is permitted, the relay closes and connects the charge source to the lithium bank. When the BMS issues a charge disconnect signal (for example, due to high cell voltage or temperature), the Cyrix-Li-charge opens immediately, protecting the battery from overcharge.\u003c\/p\u003e\n\n\u003cp\u003eAt 230A, this unit handles substantial charge currents from alternators, DC-DC chargers or shore power converters in 24V and 48V systems. The microprocessor logic prevents the relay from chattering or cycling unnecessarily, which extends both relay and battery life. This makes it a practical choice for professional installations in narrowboats, commercial vehicles, off-grid cabins and similar applications where a lithium house bank is charged from a secondary source.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CYR020230430\u003c\/li\u003e\n  \u003cli\u003eVoltage: 24\/48V\u003c\/li\u003e\n  \u003cli\u003eContinuous current rating: 230A\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076022282\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLithium house bank charging from a starter battery or alternator in marine installations.\u003c\/li\u003e\n  \u003cli\u003e24V or 48V off-grid systems combining a lithium battery bank with an auxiliary charge source.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicle auxiliary power systems using LiFePO4 batteries.\u003c\/li\u003e\n  \u003cli\u003eNarrowboat and canal boat electrical systems with lithium battery upgrades.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and mobile installations requiring BMS-controlled charge isolation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron Cyrix-Li-charge 24\/48V-230A intelligent charge relay\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 experienced marine\/vehicle electrical engineer. The Cyrix-Li-charge must be wired in conjunction with a compatible lithium BMS that provides a charge disconnect output signal. Incorrect wiring without a BMS control signal will prevent the unit from functioning as intended and may not protect the lithium battery from overcharge. Ensure all cabling is rated for the 230A continuous load and that appropriate fusing is fitted on both battery connections.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60201800008014,"sku":"CYR020230430","price":132.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CYR020230430_-_Cyrix-Li-charge_24-48V-230A_intelligent_charge_relay.webp?v=1784819087","url":"https:\/\/voltaconsolar.com\/products\/victron-cyrix-li-charge-24-48v-230a","provider":"VoltaconSolar","version":"1.0","type":"link"}
