Engineered for reliability in touring, 4WD, caravan and marine setups, it ensures your auxiliary system receives charge only when the start battery is at a safe voltage—protecting your cranking battery from accidental discharge.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWhen the engine is running and the start battery reaches the preset voltage threshold, the relay closes to begin charging the auxiliary battery. Once the engine is switched off and voltage drops, the relay opens to isolate the batteries, ensuring accessories powered from the auxiliary system never drain the main battery.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul role=\"list\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eAutomatic voltage‑sensing operation\u003c\/strong\u003e for hands‑free dual‑battery management\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eProtects the start battery\u003c\/strong\u003e by isolating loads when the engine is off\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eCloses only when safe voltage is reached\u003c\/strong\u003e to begin auxiliary charging\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eOpens on shutdown\u003c\/strong\u003e to prevent flattening the primary battery\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eSuitable for 12V and 24V systems\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003e100A rating\u003c\/strong\u003e for robust, high‑current applications\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\n\u003cul role=\"list\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e4WD dual‑battery systems\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eCaravan and camper auxiliary power\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eMarine and off‑grid electrical setups\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eProtecting start batteries from accessory drain\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Baintech","offers":[{"title":"Default Title","offer_id":52337591255323,"sku":null,"price":80.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0792\/0130\/4859\/files\/BTVCR100.webp?v=1781217343","url":"https:\/\/eastcoastspares.com.au\/products\/baintech-voltage-control-relay-12v-24v-100a","provider":"East Coast Spares","version":"1.0","type":"link"}
