Unlike traditional jump starters that sit in the trunk waiting for emergencies, BS300 stays connected to your battery and automatically assists every engine start. With up to 1000A starting assist for most 12V vehicles, it helps keep your vehicle ready to start whenever you need it.\u003c\/li\u003e\n\u003cli\u003eHELP YOUR BATTERY LAST LONGER: Every engine start takes a toll on your battery—and over thousands of starts, that wear adds up. BS300 helps share 50%-100% of the cranking load with every start, reducing the stress placed on your battery over time. Less strain. Longer battery life. Fewer costly replacements.\u003c\/li\u003e\n\u003cli\u003eALWAYS READY. ZERO MAINTENANCE: Permanently connected under your hood, BS300 super starter capacitor is ready to work automatically whenever your vehicle starts. Never take it out, never charge it, and never wonder whether it's ready when you need it. Once installed, BS300 automatically wakes, supports vehicle starts, recharges from the vehicle battery when needed, and returns to sleep when its job is done. One installation. 100% automatic operation.\u003c\/li\u003e\n\u003cli\u003eGET ALERTED BEFORE YOU'RE STRANDED: Most battery problems aren't discovered until they become starting problems. Receive instant alerts when your battery needs attention, helping you address potential issues before they leave you stranded. View real-time battery voltage, charge level, operating status, and startup history anytime through the free companion app. More control. Fewer surprises.\u003c\/li\u003e\n\u003cli\u003eSAFE FOR PERMANENT INSTALLATION: BS300 permanent jump starter is designed to stay under your hood year-round. Unlike lithium battery jump starters, BS300 uses maintenance-free supercapacitors and flame-retardant materials with no risk of swelling, leakage, or thermal runaway. Built to operate from -40°F to 176°F, it remains stable through daily driving, long-term parking, and seasonal storage. Leave it connected with confidence.\u003c\/li\u003e\n\u003cli\u003eBURST POWER. BUILT TO LAST: Unlike traditional battery-based jump starters, BS300 uses advanced supercapacitor technology to deliver instant high-current power when your engine needs it most. Supercapacitors charge and discharge extremely quickly, making them ideal for engine starting, cold-weather operation, and repeated start assistance. They also withstand up to 500,000 assist cycles with minimal performance degradation over time.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e ANCEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Cell Composition:\u003c\/strong\u003e Other Than Listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 3.98\"D x 10.26\"W x 2.17\"H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Service Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ANCEL","offers":[{"title":"Default Title","offer_id":40830490476673,"sku":"B0GXP4JYKJ-color-jet-black","price":395.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0607\/5754\/0993\/files\/41xIYYc0jXL.jpg?v=1784328891","url":"https:\/\/garagenest.us\/products\/ancel-bs300-super-starter-permanently-connected-jump-starter-with-super-capacitor-battery-protection-system-health-monitoring-1000a-start-assist-for-most-12v-vehicles-40-f-176-f-color-jet-black","provider":"GarageNest","version":"1.0","type":"link"}
