It is aimed at professional installers working on marine, vehicle and off-grid applications where lithium battery protection and intelligent charge management are required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRated at 120A continuous current, suitable for 24V and 48V lithium battery systems.\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled operation monitors battery voltage and connects or disconnects automatically based on charge state.\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for lithium battery chemistries, responding to BMS charge disconnect signals to protect the battery from overcharge.\u003c\/li\u003e\n  \u003cli\u003eCombines a starter or secondary battery with the lithium bank during charging, then isolates when charging stops.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.12 kg, suitable for installation in confined spaces.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron system architectures and designed to work alongside Victron BMS products.\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 connects two battery banks together when the lithium battery is accepting a charge, and disconnects them when it is not. Unlike a standard voltage-sensing relay, this unit is designed to receive a direct signal from a lithium BMS charge disconnect output. When the BMS signals that charging must stop, the Cyrix-Li-charge opens immediately, preventing current from flowing into the lithium bank and protecting it from damage.\u003c\/p\u003e\n\n\u003cp\u003eThe 24\/48V rating makes this unit appropriate for higher-voltage systems commonly found in larger off-grid installations, commercial vehicles and marine applications. The 120A continuous rating covers most practical charging scenarios at these voltages. The microprocessor logic ensures the relay does not chatter or cycle unnecessarily, which extends contact life and reduces heat generation at the connection point.\u003c\/p\u003e\n\n\u003cp\u003eThis relay is part of Victron's Cyrix-Li range, which is distinct from the standard Cyrix battery combiners. The Li-charge variant is specifically engineered for the charge side of a lithium system, where BMS control of the charge path is a fundamental safety requirement. It should not be substituted with a standard voltage-sensing combiner in lithium applications.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CYR020120430\u003c\/li\u003e\n  \u003cli\u003eVoltage: 24\/48V\u003c\/li\u003e\n  \u003cli\u003eContinuous current rating: 120A\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.12 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076022268\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLithium battery systems in marine vessels requiring BMS-controlled charge isolation.\u003c\/li\u003e\n  \u003cli\u003eOff-grid 24V or 48V installations combining a lithium house bank with an alternator or secondary charging source.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicle conversions with lithium auxiliary battery banks at 24V or 48V.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and coach builds where a lithium battery must be isolated from the charge circuit on BMS command.\u003c\/li\u003e\n  \u003cli\u003eAny Victron-based system requiring a dedicated lithium-compatible charge relay on the positive charge path.\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 Cyrix-Li-charge 24\/48V-120A 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 system integrator familiar with lithium battery systems and BMS wiring. The Cyrix-Li-charge must be wired in accordance with the BMS charge disconnect output for correct operation. Incorrect wiring in a lithium system can result in battery damage or a safety hazard. Ensure all connections are correctly rated for the current and voltage of the system. For marine installations, follow applicable NMEA or flag-state wiring standards.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59866753007950,"sku":"CYR020120430","price":61.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CYR020120430_-_Cyrix-Li-charge_24-48V-120A_intelligent_charge_relay.webp?v=1781200335","url":"https:\/\/voltaconsolar.com\/products\/victron-cyrix-li-charge-24-48v-120a","provider":"VoltaconSolar","version":"1.0","type":"link"}
