Designed for 12V dual-battery installations, the relay connects battery banks when charging voltage is detected and separates them when voltage drops. This helps keep both batteries charged while protecting the starting battery from unnecessary discharge.\u003c\/p\u003e\n\u003cp\u003eSupporting alternators up to 120A, the Bluewater 9800-7101-00 is well suited for boats with separate starting and house batteries, including sailboats and fishing boats, as well as RV applications. The start-isolation feature temporarily disconnects house loads during engine cranking, helping protect sensitive electronics from voltage fluctuations. An under-voltage lockout prevents the relay from closing when system voltage is too low, with a 9.5V lockout threshold for 12V systems.\u003c\/p\u003e\n\u003cp\u003eDual-color status LEDs provide at-a-glance indication of fault, charging, discharging, combine, start isolation, and override conditions. The relay is rated for 120A continuous operation and 140A intermittent operation, with support for cable sizes up to 4\/0 AWG. Its IP67 protection rating helps guard against water and dust intrusion, while ignition protection makes it suitable for gasoline-powered boats. The black relay is supplied with a base and is designed for dependable automatic battery control in demanding environments.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003cbr\u003eContinuous rating: 120A; intermittent rating: 140A; alternator support: up to 120A; system voltage: 12V; maximum voltage: 48VDC; under-voltage lockout: 9.5V for 12V systems; cable support: up to 4\/0 AWG; protection: IP67 and ignition protected; color: black with base.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAutomatic battery management connects battery banks 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\u003eUnder-voltage lockout prevents closing when a 12V battery system falls below 9.5V.\u003c\/li\u003e\n\u003cli\u003eDual-color status LEDs indicate fault, charging, discharging, combine, start isolation, and override modes.\u003c\/li\u003e\n\u003cli\u003e120A continuous and 140A intermittent current ratings support demanding dual-battery applications.\u003c\/li\u003e\n\u003cli\u003eSupports alternators up to 120A and cable sizes up to 4\/0 AWG.\u003c\/li\u003e\n\u003cli\u003eIP67 waterproof protection and ignition-safe construction are suitable for gasoline-powered boats.\u003c\/li\u003e\n\u003cli\u003eBlack finish with base for marine and recreational vehicle installations.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bluewater Enterprises","offers":[{"title":"Default Title","offer_id":67747208102073,"sku":"BWE9800710100","price":78.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/BWE9800710100_001.jpg?v=1792187597","url":"https:\/\/atticusgoods.com\/products\/bluewater-enterprises-9800-7101-00-automatic-charging-relay-120a-12v-black","provider":"Atticus Goods","version":"1.0","type":"link"}
