{"product_id":"bb2413","title":"Sterling Power Saturn BB2413 | 12V\/24V to 24V 13A Bidirectional DC-DC Battery Charger","description":"\u003cp\u003eThe BB2413 fills a specific niche in the Saturn Series lineup — a DC-DC charger that steps up from a 12V or 24V alternator source to charge a 24V house battery bank at 13A. It's the right tool for builds that run a 24V auxiliary system in a vehicle with a 12V or 24V starter system, where a larger cross-voltage charger like the BB1224120 delivers more current than the application requires.\u003c\/p\u003e\n\n\u003cp\u003eAuto-detecting input means the BB2413 works correctly whether connected to a 12V or 24V source, with no manual configuration required when moving between platforms. It's fully compatible with Euro 5\/6+ smart alternators, correctly interpreting variable voltage signals that would cause traditional relays or older-generation chargers to fault or undercharge.\u003c\/p\u003e\n\n\u003cp\u003eThe BB2413 runs Sterling's standard Saturn 4-stage charge profile with six preset battery type options covering gel, AGM, calcium, open lead-acid, and two lithium profiles including LiFePO4. Low-temperature lithium cutoff protects cells from cold-weather charging damage. At 96% efficiency, heat rejection is minimal and the thermostatically controlled variable-speed fan keeps the unit quiet under light load.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBidirectional Reverse Charging:\u003c\/strong\u003e When your 24V house bank climbs above threshold, the BB2413 automatically feeds current back to the starter battery to keep it maintained at float voltage — so solar looking after the house bank keeps your starter healthy too. Jump Start Assist mode forces a 20-minute reverse charge cycle if the starter battery drops too low to start the engine.\u003c\/p\u003e\n\n\u003cp\u003eOutput is adjustable to 100%, 85%, or 65% via the optional BBR remote, useful for managing alternator load alongside solar or in multi-unit parallel configurations.\u003c\/p\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e BB2413\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Voltage:\u003c\/strong\u003e 12V \/ 24V auto-select\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 24V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContinuous Output:\u003c\/strong\u003e 13A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEfficiency:\u003c\/strong\u003e 96%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling:\u003c\/strong\u003e Thermostatically controlled variable-speed fan\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmart Alternator Compatible:\u003c\/strong\u003e Yes (Euro 5\/6+)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBidirectional:\u003c\/strong\u003e Yes — reverse charge + Jump Start Assist\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Profiles:\u003c\/strong\u003e 6 presets (gel, AGM, calcium, flooded, 2x lithium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow-temp Lithium Cutoff:\u003c\/strong\u003e Yes (0°C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRemote:\u003c\/strong\u003e Optional BBR remote for output adjustment\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STERLING POWER NORTH AMERICA","offers":[{"title":"Default Title","offer_id":48360403566784,"sku":"BB2413","price":275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0525\/3188\/8320\/files\/BB2413.webp?v=1780512283","url":"https:\/\/overlandkitted.com\/products\/bb2413","provider":"Overland Kitted","version":"1.0","type":"link"}
