It supports dual-input charging—either from the starter battery via the alternator of the vehicle or directly from solar panels—ensuring your service battery stays fully charged in any setting. Built-in MPPT technology maximises solar efficiency, while a three-stage smart charging algorithm (bulk, absorption, float) safely and accurately charges gel, AGM, and lithium batteries to 100%, extending their lifespan. An integrated Voltage Sensitive Relay (VSR) intelligently isolates starter and house batteries to prevent interference and guarantee reliable engine starts. Comprehensive protections—including temperature compensation, overvoltage, overcurrent, overheating, reverse polarity, and reverse current—ensure complete safety for both device and batteries\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e[Temperature Compensation]: Equipped with a temperature sensor port for precise compensation in extreme heat or cold, ensuring stable battery charging.\u003c\/li\u003e\n\u003cli\u003e[Remote Monitoring Device]: Monitor remotely and receive real-time updates via the BT-2 bluetooth module and the DC Home app anytime, anywhere.\u003c\/li\u003e\n\u003cli\u003e[Efficient Heat Dissipation]: Die-cast aluminium housing enables efficient, low-noise cooling to significantly extend its service life.\u003c\/li\u003e\n\u003cli\u003e[Soft-Start Circuit Design]: Gently powers up the charger to protect equipment and prevent draining the starter battery.\u003c\/li\u003e\n\u003cli\u003e[Removable Side Cover]: Anti-static cover prevents ESD damage from human contact, ensuring long-term safe operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cb\u003e:\u003c\/b\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProduct Dimensions: 24.4W x 14.6D x 9.6H cm\u003c\/p\u003e\n\u003cp\u003eMaterial: PC + ABC + Aluminium Alloy\u003c\/p\u003e\n\u003cp\u003eColour: Black\u003c\/p\u003e\n\u003cp\u003eModel: RBC50D1S\u003c\/p\u003e\n\u003cp\u003eRated Charging Power: 660W\u003c\/p\u003e\n\u003cp\u003eRated Charging Current: 50A\u003c\/p\u003e\n\u003cp\u003eSystem Voltage: 12V DC\u003c\/p\u003e\n\u003cp\u003eOutput Voltage Range:9-16V DC\u003c\/p\u003e\n\u003cp\u003eMaximum Solar Input Voltage: 50V\u003c\/p\u003e\n\u003cp\u003eMaximum Solar Input Power: 660W\u003c\/p\u003e\n\u003cp\u003eSelf-consumption: 60mA\u003c\/p\u003e\n\u003cp\u003eOperating Temperature: -35°C to 65°C\u003c\/p\u003e\n\u003cp\u003eMPPT Technology: Yes\u003c\/p\u003e\n\u003cp\u003eSupported Battery Types: Gel, AGM, Lithium\u003c\/p\u003e\n\u003cp\u003eBuilt-in Voltage-Sensitive Relay(VSR): Yes\u003c\/p\u003e\n\u003cp\u003e3-Stage Smart Charging: Bulk, Absorption, Float\u003c\/p\u003e\n\u003cp\u003eRecommended Fuse: 60A ANL(Not Included)\u003c\/p\u003e\n\u003cp\u003eCharging Efficiency: Up to 97%\u003c\/p\u003e\n\u003cp\u003eCommunication Protocol: RS485 Communication\u003c\/p\u003e\n\u003cp\u003eRemovable Side Covers: Yes\u003c\/p\u003e\n\u003cp\u003eTemperature Compensation: Yes\u003c\/p\u003e\n\u003cp\u003eOver-Voltage Protection: Yes\u003c\/p\u003e\n\u003cp\u003eOver-Current Protection: Yes\u003c\/p\u003e\n\u003cp\u003eReverse Polarity Protection: Yes\u003c\/p\u003e\n\u003cp\u003eOver-Temperature Protection: Yes\u003c\/p\u003e\n\u003cp\u003eReverse Current Protection: Yes\u003c\/p\u003e\n\u003cp\u003eMulti-Alternator Compatibility: Conventional and Smart Alternators\u003c\/p\u003e\n\u003cp\u003eInstallation Required: Yes\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cb\u003ePackage\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cb\u003e\u003cspan\u003eContents\u003c\/span\u003e\u003c\/b\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cb\u003e:\u003c\/b\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1 x Battery Charger\u003c\/p\u003e\n\u003cp\u003e1 x User Manual\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cb\u003ePackage Specifications\u003c\/b\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePackage Dimensions (WxDxH): 27.8 x 22 x 15cm\u003c\/p\u003e\n\u003cp\u003eGross Weight: 2.6kg\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cb\u003eNotes：\u003c\/b\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e-Compatible with Renogy One M1 and BT-2, each of which is available for separate purchase.\u003c\/p\u003e\n\u003cp\u003e-A fuse is required for installation(not included).\u003c\/p\u003e\n\u003cp\u003e-Despite efforts for accuracy, there may be some reasonable error due to manual measurement.\u003c\/p\u003e\n\u003cp\u003e-Actual product colours may vary due to monitor settings \u0026amp; lightings.\u003cbr\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"EVER STRONG","offers":[{"title":"Default Title","offer_id":53089257095392,"sku":"AJ1354","price":999.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0607\/7490\/8128\/files\/51zRAdSKRCL._AC_SX679.jpg?v=1781601785","url":"https:\/\/www.ever-strong.co.uk\/products\/12v-50a-dc-dc-on-board-battery-charger-with-mppt-for-gel-agm-and-lithium-batteries-aj1354","provider":"EVER STRONG","version":"1.0","type":"link"}
