This kit enables you to power auxiliary systems like winches, lights, and refrigerators without draining your main starting battery, preventing you from getting stranded. It utilizes a 140A Voltage Sensitive Relay (VSR) that automatically engages at 13.3V to charge both batteries when the engine is running and disengages at 12.8V when the engine is off, effectively isolating the starter battery.","brand":"True Amps","offers":[{"title":"Default Title","offer_id":52664181031224,"sku":"DBK12LRG-GMC","price":132.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/684561834.webp?v=1784334842","url":"https:\/\/store.motormia.co\/products\/12v-140a-dual-battery-isolator-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
