It is used in 12V and 24V battery systems and is available in 40A or 80A maximum continuous current versions, both built around a two-battery layout.\u003c\/p\u003e\u003cp\u003eOn a boat, this type of unit is most often used where interruption is not acceptable, such as an electronic engine control system or another essential DC circuit. Two DC power sources can feed the same load in parallel, and if one source drops out, the other can continue supplying the critical load.\u003c\/p\u003e\u003cp\u003eThe combiner uses Schottky diodes for low voltage drop, with approximately 0.3 V drop at low current and approximately 0.45 V at rated output. Both variants use M6 bolt connections and share the same 60 x 120 x 75 mm housing size, which helps when planning a battery compartment, technical locker, or protected electrical panel installation.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eCombines two DC power sources to supply one mission-critical DC load.\u003c\/li\u003e\n\u003cli\u003eAvailable in 40A and 80A maximum continuous current versions for different load requirements.\u003c\/li\u003e\n\u003cli\u003eSuitable for 12V and 24V battery systems commonly found on marine DC installations.\u003c\/li\u003e\n\u003cli\u003eSchottky diode design keeps voltage drop low, approximately 0.3 V at low current and approximately 0.45 V at rated output.\u003c\/li\u003e\n\u003cli\u003eFailure of one connected source does not interrupt power to the critical load.\u003c\/li\u003e\n\u003cli\u003eM6 bolt connections support secure cable termination in a vibration-prone onboard electrical space.\u003c\/li\u003e\n\u003cli\u003eCompact 60 x 120 x 75 mm footprint with the same 0.8 kg weight across both variants.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product is offered in two configurations that differ by maximum continuous current rating.\u003c\/p\u003e\u003cp\u003eBoth variants are made for two batteries, work with 12V and 24V nominal battery systems, use M6 bolt connections, and share the same dimensions and weight. The current rating is the key selection point when matching the combiner to the protected DC load.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBCD000402000: Maximum Continuous Current 40A. This is the lower-current configuration in the range and keeps the same two-source, one-load layout as the 80A version.\u003c\/li\u003e\n\u003cli\u003eBCD000802000: Maximum Continuous Current 80A. This is the higher-current configuration in the range while retaining the same voltage support, connection style, and housing size.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the unit close enough to the batteries and protected load to keep cable runs sensible, while still leaving room for properly sized conductors, terminals, and service access. Because the housing can become hot in operation, it must be mounted on a non-flammable surface with adequate clearance around it.\u003c\/p\u003e\u003cp\u003eThe three-bolt layout is straightforward: each DC source connects to an input, and the protected DC load connects to the output. Cable sizing, overcurrent protection, and installation practices should match the current rating selected and the vessel’s DC electrical standards.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eThe Argo Diode Battery Combiner is a simple fit for boats that need a dedicated backup path for an essential DC consumer without adding switching complexity at the load. It can be used in installations where two batteries or DC sources are available and the priority is keeping one critical circuit alive.\u003c\/p\u003e\u003cp\u003eThis product is a practical match for marine electrical refits, engine control power feeds, and other onboard DC systems where a single source failure should not shut down the connected equipment. It is not a charger or a battery monitor, so it should be integrated as part of a complete DC system with correct fusing and wiring.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"40A","offer_id":52581955109045,"sku":"QBP535861-V1","price":41.48,"currency_code":"USD","in_stock":true},{"title":"80A","offer_id":52581955141813,"sku":"QBP535861-V2","price":45.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1336115_qbp535861.webp?v=1780201734","url":"https:\/\/www.qualityboatparts.com\/products\/qbp535861","provider":"Quality Boat Parts","version":"1.0","type":"link"}
