It is built for RVs, camper vans, trucks and boats where the alternator alone never quite fills the house bank.\u003c\/p\u003e\u003cp\u003eWire it between the starter battery and the house battery; there is no alternator modification, no ECU tampering and no warranty issue. It switches on at 13.3V and off at 13.0V (double for 24V input), so it uses surplus alternator power rather than draining the starter battery, and Sterling says it charges 5 to 20 times faster than an alternator on its own. It is designed for smart alternators and regenerative braking on modern engines.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eActivation modes: automatic, manual (for remote switching), and regenerative-braking modes with or without an ignition feed\u003c\/li\u003e\n\u003cli\u003eIn regenerative-braking mode the input may drop to 12.2V (double for 24V) before it switches off\u003c\/li\u003e\n\u003cli\u003eBoosts or reduces voltage so the house battery gets the right profile whatever the alternator does\u003c\/li\u003e\n\u003cli\u003e4-stage charging with 9 preset battery types including AGM, LiFePO4, gel, flooded and sealed lead acid\u003c\/li\u003e\n\u003cli\u003eCustom charge profile set from the front panel\u003c\/li\u003e\n\u003cli\u003eNight setting runs at half power to keep fan noise down\u003c\/li\u003e\n\u003cli\u003eFireproof plastic case with no screws to corrode, thermal power reduction and multi-stage fan cooling\u003c\/li\u003e\n\u003cli\u003eOptional BBURC remote with 10 m cable (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e BB241235\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput voltage:\u003c\/strong\u003e 24V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput voltage:\u003c\/strong\u003e 12V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent rating (Sterling lists as amps in):\u003c\/strong\u003e 35A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x D):\u003c\/strong\u003e 190 x 160 x 95 mm (7.5 x 6.3 x 3.7 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit weight:\u003c\/strong\u003e 1.4 kg (3.09 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery types:\u003c\/strong\u003e AGM, LiFePO4, gel, flooded, sealed lead acid and more (9 presets) plus custom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTurn on \/ off:\u003c\/strong\u003e 26.6V \/ 26.0V\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Sterling Power with Sterling Power's warranty.
