It auto-selects between 12V and 24V input, works with Euro 6+ smart alternators, and includes a reverse-charging mode that can top up the starter battery from the 48V bank in an emergency, plus a dedicated Jump Start Assist mode.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Specs:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInput: 12V or 24V, auto-select (9-32V range)\u003c\/li\u003e\n\u003cli\u003eOutput: 48V nominal\u003c\/li\u003e\n\u003cli\u003ePower Rating: 750W (peak)\u003c\/li\u003e\n\u003cli\u003eEfficiency: up to 96%\u003c\/li\u003e\n\u003cli\u003eBattery Profiles: 6 presets plus custom profile\u003c\/li\u003e\n\u003cli\u003eFeatures: reverse charging (starter battery maintenance), Jump Start Assist, low-temperature lithium protection\u003c\/li\u003e\n\u003cli\u003eOptional Accessory: BBR remote with live monitoring and current limiting (100%\/85%\/65%)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePart of Sterling's Saturn series DC-DC charging line — a solid choice for anyone stepping a 12V or 24V vehicle system up to a 48V lithium battery bank.\u003c\/p\u003e","brand":"Sterling Power","offers":[{"title":"Default Title","offer_id":47631049654462,"sku":null,"price":700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/0149\/8558\/files\/Sterling12Vto48V750WBatterytoBatteryChargerBB124865.webp?v=1784509647","url":"https:\/\/lightharvestsolar.com\/products\/sterling-12v-to-48v-750w-battery-to-battery-charger-bb124865","provider":"LightHarvest Solar","version":"1.0","type":"link"}
