Intended for marine applications, recreational vehicles, and standalone systems, this kit provides reliable electrical management without manual intervention.\n\u003c\/p\u003e\n\u003ch3\u003eDual Circuit Plus™ e-Series Battery Switch\u003c\/h3\u003e\n\u003cp\u003e\n    At the core of this system is the Dual Circuit Plus™ e-Series battery switch. This component isolates the starter and house battery banks and allows manual combination for emergency starting. It offers multiple switching positions for managing both banks while maintaining isolation to minimize the risk of draining the starter battery. It can handle continuous current of 350 amps per circuit, intermittent current of 525 amps (5 minutes), and starting current of 700 amps (30 seconds). Its maximum operating voltage is 32 volts DC. For optimal conductivity and corrosion resistance, the terminal studs are made of tinned copper. The switch complies with ABYC requirements for battery switches and is rated IP66, ensuring protection against powerful water jets. It also meets CE, UL 1500, and SAE J1171 standards for ignition protection.\n\u003c\/p\u003e\n\u003ch3\u003eAutomatic Charging Relay (SI-ACR) 120A\u003c\/h3\u003e\n\u003cp\u003e\n    The kit includes a 120-amp automatic charging relay (SI-ACR). This relay automatically combines batteries during charging and isolates them during discharge or when the engine is not charging, optimizing load sharing between the two banks without requiring regulator adjustment. Its rated capacity is 120 amps continuous and 210 amps intermittent (5 minutes). It is compatible with 12V or 24V DC systems. The ACR features a Start Isolation function that protects sensitive electronics from voltage drops and spikes during engine start-up. An under-voltage lockout function prevents combination if the voltage of a battery is below 9.5V (12V system) or 19V (24V system). The relay has an IP67 rating, making it resistant to temporary immersion up to one meter, and is certified to CE, ISO 8846, UL 1500, and SAE J1171 standards for ignition protection. An LED indicator provides a visual diagnostic of voltage status and relay function.\n\u003c\/p\u003e\n\u003ch3\u003ePositioning and Integration\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eBLUE SEA Add-A-Battery 120A\u003c\/strong\u003e kit is positioned as a robust solution for alternators up to 120 amps. It outperforms the Mini Add-A-Battery 7649 version (for alternators up to 65A) in terms of current capacity, making it suitable for more demanding marine engines and electrical systems. The kit ensures efficient energy management, protection of electronic equipment, and the ability to combine batteries for emergency starting when needed. The M10 (3\/8\"-16) terminal studs on both components facilitate robust and standardized connections.\n\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":55861159264596,"sku":"7650-BSS","price":199.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_-_Hero_-_BLUE_SEA_Add-A-Battery_Kit_-_120A_7650-BSS_-_Ref_09f4baaf.jpg?v=1779203588","url":"https:\/\/skysat.fr\/en-us\/products\/blue-sea-add-a-battery-kit-battery-management-120a","provider":"Skysat","version":"1.0","type":"link"}
