It connects and disconnects loads based on battery state, protecting lithium cells from over-discharge without requiring manual intervention. Suitable for marine, vehicle and off-grid installations where load management is critical.\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-load DC circuits at 24V or 48V.\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled switching logic responds to battery voltage thresholds rather than simple relay timers.\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for lithium battery chemistries, with disconnect behaviour matched to Li-ion and LiFePO4 charge profiles.\u003c\/li\u003e\n  \u003cli\u003eAutomatically disconnects loads when battery voltage drops to a programmable low-voltage threshold, preventing deep discharge damage.\u003c\/li\u003e\n  \u003cli\u003eReconnects loads once the battery has recovered to a safe voltage level, without manual reset.\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 lithium battery systems and BMS communication where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-Li-load operates by monitoring battery voltage and switching a high-current relay to connect or isolate the load circuit. Unlike a standard battery combiner, this unit is built around the specific voltage windows of lithium batteries. It will not reconnect a load prematurely after a low-voltage event, which is a common cause of repeated deep discharge in lithium systems.\u003c\/p\u003e\n\n\u003cp\u003eAt 230A, the relay handles substantial DC loads including inverters, winches, bow thrusters and high-draw appliances. The 24\/48V dual-voltage compatibility makes it applicable across a wide range of system designs without requiring separate part numbers for each voltage. The microprocessor logic also filters out brief voltage dips, so transient loads do not trigger unnecessary disconnections.\u003c\/p\u003e\n\n\u003cp\u003eThis unit is part of Victron's Cyrix range, which is widely used in marine, motorhome and off-grid installations. It is not a BMS replacement but works alongside a BMS to manage load-side disconnection based on voltage conditions.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CYR020230450\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076022299\u003c\/li\u003e\n  \u003cli\u003eVoltage: 24V \/ 48V\u003c\/li\u003e\n  \u003cli\u003eContinuous current rating: 230A\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.3 kg\u003c\/li\u003e\n  \u003cli\u003eBattery chemistry: Lithium (Li-ion, LiFePO4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLoad disconnection in 24V or 48V lithium battery systems on narrowboats, yachts and motorhomes.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and mobile installations where automatic load shedding is required.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicle auxiliary power systems using lithium batteries.\u003c\/li\u003e\n  \u003cli\u003eAny DC system where loads must be isolated to prevent lithium battery over-discharge.\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-load 24\/48V-230A intelligent charge relay 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 electrician or experienced marine\/vehicle electrical engineer. The unit must be wired in line with the load circuit, not the charge circuit. Ensure cable sizing is appropriate for 230A continuous current and that suitable fusing is installed on the battery side. This unit is intended for lithium battery systems only and should not be used with lead-acid batteries without confirming voltage threshold compatibility. For off-grid and marine installations, follow applicable wiring regulations and standards.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60201800270158,"sku":"CYR020230450","price":132.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CYR020230450_-_Cyrix-Li-load_24-48V-230A_intelligent_charge_relay.webp?v=1784819100","url":"https:\/\/voltaconsolar.com\/products\/victron-cyrix-li-load-24-48v-230a-charge-relay","provider":"VoltaconSolar","version":"1.0","type":"link"}
