It is intended for 12V and 24V systems and is rated to 120A continuous. This device is aimed at professional installers working on marine, vehicle and off-grid applications 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 120A continuous for 12V and 24V DC systems.\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled operation monitors battery voltage and disconnects loads automatically when the battery drops below a safe threshold.\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for lithium battery chemistries, responding to the steeper voltage curves that characterise LiFePO4 and similar cells.\u003c\/li\u003e\n  \u003cli\u003eReconnects loads automatically once the battery voltage recovers to a safe level, without manual intervention.\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 lithium battery systems and can receive a remote on\/off signal from a battery management system (BMS).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-Li-load works by monitoring the terminal voltage of a lithium battery and opening the relay contact when voltage falls to a level that indicates the battery is approaching full discharge. Unlike a simple voltage cut-off relay, the microprocessor logic accounts for the relatively flat discharge curve of lithium cells, where voltage drops sharply only near the end of capacity. This makes accurate, timely disconnection possible without premature load shedding during normal use.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is designed to sit between the lithium battery and non-essential or secondary loads, such as lighting circuits, auxiliary consumers or habitation loads. Essential loads or the main drive circuit are typically handled separately. When used alongside a Victron BMS, the BMS can assert a remote signal to force the Cyrix-Li-load open independently of the voltage threshold, providing an additional layer of protection during fault conditions or cell imbalance events.\u003c\/p\u003e\n\n\u003cp\u003eThe 120A rating makes this relay suitable for moderate to high load circuits in 12V and 24V installations. The dual voltage compatibility means a single part number covers both system voltages, which simplifies stock management for installers working across different vessel or vehicle types.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CYR010120450\u003c\/li\u003e\n  \u003cli\u003eSystem voltage: 12V \/ 24V DC\u003c\/li\u003e\n  \u003cli\u003eContinuous current rating: 120A\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.12 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076022190\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLithium battery load protection in marine and narrowboat electrical systems.\u003c\/li\u003e\n  \u003cli\u003eAuxiliary load disconnection in campervans, motorhomes and off-road vehicles with lithium house batteries.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabin and caravan systems where over-discharge protection is required for LiFePO4 battery banks.\u003c\/li\u003e\n  \u003cli\u003eSecondary load management in 12V or 24V commercial vehicle fit-outs.\u003c\/li\u003e\n  \u003cli\u003eIntegration with Victron BMS for automated load shedding during low-state-of-charge or fault conditions.\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 12\/24V-120A intelligent load 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. The Cyrix-Li-load must be wired in series with the load circuit it is intended to protect, not in the main battery positive feed. Correct fusing of the load circuit is required in accordance with the cable rating and applicable wiring standards. When integrating with a Victron BMS, refer to the BMS wiring documentation to ensure the remote on\/off connection is made correctly. This unit is not suitable for lead-acid battery systems where standard Cyrix combiners should be used instead.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59866753073486,"sku":"CYR010120450","price":52.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CYR010120450_-_Cyrix-Li-load_12-24V-120A_intelligent_load_relay.webp?v=1781200340","url":"https:\/\/voltaconsolar.com\/products\/victron-cyrix-li-load-12-24v-120a-load-relay","provider":"VoltaconSolar","version":"1.0","type":"link"}
