Designed for marine and RV applications, this 140-amp automatic charging relay supports dual-battery setups such as starter and house battery systems, navigation and lighting batteries, and trolling motor accessory batteries.\u003c\/p\u003e\u003cp\u003eThe relay automatically connects batteries during charging and isolates them when voltage drops, helping manage battery power without requiring manual switching. Start Isolation temporarily disconnects house loads during engine cranking to help protect sensitive electronics. Dual-color LED indicators provide real-time status information for Fault, Charging, Discharging, Combine, Start Isolation, and Override modes, making system operation easier to monitor.\u003c\/p\u003e\u003cp\u003eWith support for alternators up to 120 amps, the Bluewater auto charging relay is suited to high-output charging systems. Under Voltage Lockout prevents the relay from closing when battery voltage is too low, with thresholds of 9.5 volts for 12-volt systems and 19 volts for 24-volt systems. Its IP67 waterproof and ignition-protected design is intended for demanding marine and recreational vehicle environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAutomatic battery management: Connects batteries during charging and isolates them when voltage drops.\u003c\/li\u003e\n\u003cli\u003eStart Isolation: Temporarily disconnects house loads during engine cranking to help protect sensitive electronics.\u003c\/li\u003e\n\u003cli\u003eHigh-output support: Compatible with alternators up to 120 amps.\u003c\/li\u003e\n\u003cli\u003eDual-color LED indicators: Shows Fault, Charging, Discharging, Combine, Start Isolation, and Override status.\u003c\/li\u003e\n\u003cli\u003eUnder Voltage Lockout: Prevents relay closure when voltage is below the specified threshold.\u003c\/li\u003e\n\u003cli\u003eMarine-ready construction: IP67 waterproof and ignition protected for marine and RV applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eProduct Details:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Bluewater\u003c\/li\u003e\n\u003cli\u003eModel: 9800-7101-00\u003c\/li\u003e\n\u003cli\u003eProduct type: Automatic charging relay\u003c\/li\u003e\n\u003cli\u003eSystem voltage: 12 volts\u003c\/li\u003e\n\u003cli\u003eContinuous rating: 120 amps\u003c\/li\u003e\n\u003cli\u003eIntermittent rating: 140 amps\u003c\/li\u003e\n\u003cli\u003eMaximum voltage: 48 VDC\u003c\/li\u003e\n\u003cli\u003eCable size: 4\/0 AWG\u003c\/li\u003e\n\u003cli\u003eIntended use: Boats, sailboats, fishing boats, and RV applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eChoose the Bluewater 9800-7101-00 Auto Charging Relay for organized, automatic battery management in compatible 12-volt marine and recreational vehicle systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSEO Meta Description:\u003c\/strong\u003e\u003cbr\u003eBluewater 12V auto charging relay with 140-amp intermittent rating, Start Isolation, LED status indicators, and IP67 protection for marine systems.\u003c\/p\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eTruck Freight: No\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eOversized: No\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Bluewater","offers":[{"title":"Default Title","offer_id":44934096683097,"sku":"111083","price":96.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/1818\/2489\/files\/111083XL.jpg?v=1789754849","url":"https:\/\/www.marinepartsonly.com\/products\/bluewater-9800-7101-00-auto-charging-relay-12v-140-amp","provider":"Marine Parts Only","version":"1.0","type":"link"}
