It is aimed at RVs, camper vans, overland rigs and boats, and is especially at home with lithium house banks. Being able to accept either 12V or 24V input makes it a flexible choice for a 48V build.\u003c\/p\u003e\u003cp\u003eIts buck-boost design converts power at 95% to 98% efficiency and limits current, so it protects your alternator while giving a lithium bank the profile it needs. It works with smart alternators on newer engines and can start from an ignition feed or by sensing engine vibration. Sterling's Saturn chargers can also run in reverse: when the house side is charged by solar or shore power, they top the starter battery back up to about 13.4V, and a jump-start assist mode forces that for 20 minutes.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBuck-boost converter, 95% to 98% efficient\u003c\/li\u003e\n\u003cli\u003eCurrent limiting, so the alternator is not overworked\u003c\/li\u003e\n\u003cli\u003eLithium safe, with a low-temperature charging trip for lithium-ion batteries\u003c\/li\u003e\n\u003cli\u003eSmart alternator compatible\u003c\/li\u003e\n\u003cli\u003eIgnition feed or vibration-sense activation\u003c\/li\u003e\n\u003cli\u003e6 preset battery types\u003c\/li\u003e\n\u003cli\u003eSelf-recovering protection against under-voltage, input and output over-voltage, over-current and over-temperature\u003c\/li\u003e\n\u003cli\u003eReverse charging to maintain the starter battery (on by default, can be turned off) and a 20-minute jump-start assist mode\u003c\/li\u003e\n\u003cli\u003eCan be paralleled with other Saturn chargers for more current or redundancy\u003c\/li\u003e\n\u003cli\u003eOptional BBR remote (sold separately) for live readings, custom profiles and 65\/85\/100% power limits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e BB124865\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e 12V or 24V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e 48V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 750W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency:\u003c\/strong\u003e 95% to 98% (Saturn series)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 5 years (Sterling, from Nov 1, 2024)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Sterling Power with Sterling Power's warranty.
