It joins battery banks in parallel while a charging source is active and separates them again once charging stops, so a starter battery cannot be drained by auxiliary loads. It suits marine, vehicle and off-grid setups where two battery banks need managing without a manual switch.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic combining\u003c\/strong\u003e, the relay closes and opens based on voltage thresholds, with no manual switching needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent rating\u003c\/strong\u003e, 230A continuous at 12V or 24V DC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStarter protection\u003c\/strong\u003e, disconnects the auxiliary bank once system voltage drops below the set threshold.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemistry compatible\u003c\/strong\u003e, works with lead-acid, AGM, gel and lithium batteries as it responds to voltage rather than chemistry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact build\u003c\/strong\u003e, weighs 0.3kg for installation in tight spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharger compatible\u003c\/strong\u003e, works alongside alternators, solar chargers and shore power chargers without extra configuration.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow it works\u003c\/h2\u003e\u003cp\u003eThe Cyrix-ct monitors the voltage of both battery banks. When either reaches a pre-set charge voltage, the internal relay closes and the banks are connected in parallel so both receive charge current. When voltage falls back below the threshold, the relay opens and the banks separate again, stopping a discharged auxiliary bank from pulling down the starter battery.\u003c\/p\u003e\u003cp\u003eThe\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52061066068256,"sku":"CYR010230010","price":102.89,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-cyr010230010-1.webp?v=1785510696","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-cyrix-ct-battery-combiner-230a","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
