{"product_id":"qbp442825","title":"Blue Sea Systems Triple Battery Bank Management Panel, 12\/24V DC, 32V Max","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Blue Sea Systems Triple Battery Bank Management Panel is a battery switching and circuit protection panel for twin-engine boats using three battery banks. It combines two Dual Circuit Plus battery switches with push-button 24-hour circuit breakers and a 100A C-Series flat rocker circuit breaker, giving the helm or electrical panel a clearer way to manage start and house battery circuits.\u003c\/p\u003e\u003cp\u003eThis panel supports 12V and 24V DC systems with a maximum voltage of 32V DC. It is built around separate engine and house circuit control, emergency cross-connect between isolated battery banks, and protection for sensitive electronics from voltage sags and spikes that can happen during engine cranking.\u003c\/p\u003e\u003cp\u003eIt is a practical fit for boats that need organized battery control without turning battery switching into a complicated routine. With the addition of two Automatic Charging Relays, charging can be automated across three battery banks while keeping the switching layout easy to understand.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eBuilt for twin-engine battery systems with three battery banks when used with Automatic Charging Relays.\u003c\/li\u003e\n\u003cli\u003eSupports 12V and 24V DC installations, with a maximum voltage rating of 32V DC.\u003c\/li\u003e\n\u003cli\u003eSeparates engine and house circuits so house loads are less likely to drain the starting battery.\u003c\/li\u003e\n\u003cli\u003eAllows emergency cross-connect between isolated battery banks when backup starting power is needed.\u003c\/li\u003e\n\u003cli\u003eHelps protect onboard electronics from voltage spikes and sags during engine cranking.\u003c\/li\u003e\n\u003cli\u003eIncludes push-button thermal circuit breakers rated at 15A for 24-hour circuits.\u003c\/li\u003e\n\u003cli\u003eUses a 100A C-Series flat rocker circuit breaker for main circuit protection.\u003c\/li\u003e\n\u003cli\u003eIgnition protected for installation aboard gasoline-powered boats.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis panel is offered in two configurations, with the position count and panel layout changing between versions.\u003c\/p\u003e\u003cp\u003eBoth variants serve the same core battery-management role for twin-engine boats, but their current ratings, dimensions, included switch type, and number of 15A push-button breakers differ by configuration.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e8689, Positions 7. This version uses two m-Series Mini Dual Circuit Plus battery switches and has a square 7.25 in by 7.25 in panel footprint, which suits installations where panel space is tighter.\u003c\/li\u003e\n\u003cli\u003e8693, Positions 11. This version uses two e-Series Dual Circuit Plus battery switches and has a wider 8.00 in by 10.50 in layout, giving more panel space for the additional 24-hour circuit breaker positions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eElectrical ratings\u003c\/h6\u003e\u003cp\u003eThe 8689 variant is rated for 300A continuous current, 450A intermittent current for 5 minutes, 1000A cranking current for 10 seconds, and 650A cranking current for 1 minute.\u003c\/p\u003e\u003cp\u003eThe 8693 variant is rated for 350A continuous current, 525A intermittent current for 5 minutes, 1000A cranking current for 10 seconds, and 750A cranking current for 1 minute.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe panel is intended for main battery distribution on boats where start and house banks need to stay isolated during normal operation but remain available for emergency parallel connection. It belongs in a dry, serviceable electrical area where the switches, breakers, labels, and wiring can be reached for operation and inspection.\u003c\/p\u003e\u003cp\u003eBecause this is a high-current battery management component, cable sizing, overcurrent protection, terminal torque, and routing should match the vessel electrical plan. Installation should also account for engine-room vibration, battery cable strain relief, and access for resetting the push-button breakers.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis panel is a strong match for twin-engine cruising boats, fishing boats, and workboats that carry separate starting and house loads. It is especially useful where electronics, refrigeration, lighting, pumps, and other house circuits need to stay separated from the starting batteries during normal use.\u003c\/p\u003e\u003cp\u003eFor owners upgrading from scattered battery switches or unclear breaker layouts, this panel brings the main battery functions into one labeled control point, making everyday switching and emergency battery linking easier to manage.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e8689: two 6011 m-Series Mini Dual Circuit Plus battery switches, three 7056 15A push-button reset circuit breakers, and one 7549 100A C-Series single-pole flat rocker circuit breaker.\u003c\/li\u003e\n\u003cli\u003e8693: two 5511e e-Series Dual Circuit Plus battery switches, four 7056 15A push-button reset circuit breakers, and one 7549 100A C-Series single-pole flat rocker circuit breaker.\u003c\/li\u003e\n\u003cli\u003e4218 square format labels and 4140 24-hour round labels.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Blue Sea Systems","offers":[{"title":"7","offer_id":52023090151605,"sku":"QBP442825-V7","price":562.99,"currency_code":"USD","in_stock":true},{"title":"11","offer_id":52023090184373,"sku":"QBP442825-V6","price":693.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1333270_qbp442825.webp?v=1780191703","url":"https:\/\/www.qualityboatparts.com\/products\/qbp442825","provider":"Quality Boat Parts","version":"1.0","type":"link"}
