It provides dedicated battery charging, sensing, and control for each of its three banks, so each connected battery gets its own regulated charge rather than a single shared output. The charger is designed for all 12 volt flooded and AGM lead acid batteries, making it a versatile choice for boats running multiple battery banks for house, starting, and accessory loads.\u003c\/p\u003e\u003cp\u003eBuilt-in protection circuitry guards against reverse polarity, over-current, over-voltage, over-temperature, and includes ignition protection, while in-line fuses add further DC wire protection. The housing is fully waterproof to an IP67 rating and shock resistant, so the Guest 2731A can be mounted in exposed engine compartments or bilge areas and used in both fresh and saltwater environments. The unit measures 14 inches deep by 11 inches wide by 10 inches high and weighs 11.1 pounds. It ships as a complete kit with the battery charger and AC\/DC power cables, and is backed by a 2 year warranty.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Guest\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 2731A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e On-board battery charger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 12 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage:\u003c\/strong\u003e 120 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 30 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Banks:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Compatibility:\u003c\/strong\u003e 12 volt flooded and AGM lead acid batteries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof Rating:\u003c\/strong\u003e IP67\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Gray\/Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 14 inches deep x 11 inches wide x 10 inches high\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 11.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e Battery charger, AC\/DC power cables\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 year warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 046904904143\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow many amps does the Guest 2731A put out?\u003c\/strong\u003e The Guest 2731A delivers 30 amps at 12 volts, split across its 3 charging banks with dedicated charging, sensing, and control for each bank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Guest 2731A waterproof?\u003c\/strong\u003e Yes, the Guest 2731A is rated IP67 for full waterproof protection and is also shock resistant, allowing installation in exposed engine compartments or bilge areas.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage does the Guest 2731A charger run on?\u003c\/strong\u003e It takes a 120 volt AC input and outputs 12 volts DC to charge connected batteries.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat types of batteries can the Guest 2731A charge?\u003c\/strong\u003e The 2731A is designed for all 12 volt flooded and AGM lead acid batteries.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many battery banks does the 2731A support?\u003c\/strong\u003e 3 separate banks, each with its own dedicated charging, sensing, and control circuit so batteries charge independently of one another.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat safety protections are built into the Guest 2731A?\u003c\/strong\u003e Reverse polarity, over-current, over-voltage, over-temperature, and ignition protection are all built in, along with in-line fuses for additional DC wire protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions and weight of the Guest 2731A?\u003c\/strong\u003e The charger measures 14 inches deep by 11 inches wide by 10 inches high and weighs 11.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Guest 2731A be used in saltwater environments?\u003c\/strong\u003e Yes, its IP67 waterproof housing is rated for both fresh and saltwater applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the Guest 2731A battery charger?\u003c\/strong\u003e The package includes the battery charger unit along with its AC\/DC power cables.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Guest 2731A come with a warranty?\u003c\/strong\u003e It is backed by a 2 year warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Guest 2731A charger housing?\u003c\/strong\u003e The housing is finished in gray and blue.\u003c\/p\u003e","brand":"Marinco","offers":[{"title":"Default Title","offer_id":49025305936091,"sku":"MAR-2731A","price":455.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/MAR-2731A__17778.1722496934.500.750.jpg?v=1785165049","url":"https:\/\/www.goodvibesmarina.com\/products\/guest-2731a-on-board-battery-charger-30-amp-12v-3-bank-120v-input","provider":"Good Vibes Marina","version":"1.0","type":"link"}
