{"product_id":"victron-ve-bus-bms-12-200-cable","title":"Victron VE.Bus Cable with RJ45","description":"\u003cp\u003eThe Victron VE.Bus to BMS 12\/200 alternator control cable connects a VE.Bus BMS to a Smart BMS 12\/200, enabling the alternator charge control feature of the BMS 12\/200 to be used in systems that already have a VE.Bus BMS installed. In this configuration, the Li-ion battery communicates its state to the VE.Bus BMS, which in turn signals the BMS 12\/200 over this cable.\u003c\/p\u003e\n\u003cp\u003eOnce connected, the BMS 12\/200 limits the alternator's charge current to a safe value for the connected lithium battery, and stops the charging process entirely if the VE.Bus BMS reports a battery alarm - protecting both the alternator and the battery from an unsafe charging condition. Without this link, the alternator charge control feature of the BMS 12\/200 is not available in a VE.Bus BMS system.\u003c\/p\u003e\n\u003cp\u003eTwo important wiring notes apply whenever this cable is used: the Li-ion battery and any loads it powers must not be connected to ground, and in this configuration the BMS 12\/200's own DC load output is not operational - loads should be wired according to the guidance in the BMS 12\/200's own manual rather than through that output.\u003c\/p\u003e\n\u003cp\u003eThis cable connects directly between the two BMS units with a fixed RJ45-style connector at each end; no additional configuration is required once it is plugged in, since the alternator charge control logic runs entirely within the BMS 12\/200 and VE.Bus BMS themselves.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\u003ch4\u003eEnables BMS 12\/200 Alternator Charge Control on VE.Bus BMS Systems\u003c\/h4\u003e\n\u003cp\u003eBridges the VE.Bus BMS and the Smart BMS 12\/200 so the BMS 12\/200's alternator charge control feature works in systems built around a VE.Bus BMS instead of a standalone setup.\u003c\/p\u003e\n\u003ch4\u003eLimits Alternator Charge Current to a Safe Value\u003c\/h4\u003e\n\u003cp\u003eOnce connected, the BMS 12\/200 automatically limits how much charge current the alternator delivers to the lithium battery, protecting both the alternator and the battery from overcurrent.\u003c\/p\u003e\n\u003ch4\u003eStops Charging on a Battery Alarm\u003c\/h4\u003e\n\u003cp\u003eThe Li-ion battery reports its state to the VE.Bus BMS, which relays it over this cable to the BMS 12\/200 - so charging stops immediately if a battery alarm is raised.\u003c\/p\u003e\n\u003ch4\u003ePlug-In Connection, No Configuration\u003c\/h4\u003e\n\u003cp\u003eConnects directly between the two BMS units with a fixed connector at each end - the charge control logic runs entirely within the BMS 12\/200 and VE.Bus BMS, with nothing to configure on the cable itself.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\u003ctable class=\"product-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003eRJ45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible With\u003c\/td\u003e\n\u003ctd\u003eVE.Bus BMS + Smart BMS 12\/200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eEnables BMS 12\/200 alternator charge control on VE.Bus BMS systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch5\u003eDatasheets and Manuals\u003c\/h5\u003e\u003cdiv\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/upload\/documents\/VE.Bus-BMS-to-BMS-12-1200-alternator-control-cable-EN.pdf\" style=\"display:flex;align-items:center;justify-content:space-between;gap:16px;border:1px solid #e2e2e2;border-radius:8px;padding:12px 16px;margin-bottom:10px;text-decoration:none;color:inherit;\" target=\"_blank\"\u003e\u003cspan style=\"display:flex;align-items:center;gap:12px;min-width:0;\"\u003e\u003cspan style=\"width:36px;height:36px;flex-shrink:0;background:#eef2f8;border-radius:6px;display:flex;align-items:center;justify-content:center;\"\u003e\u003csvg fill=\"none\" height=\"18\" style=\"display:block;\" viewbox=\"0 0 24 24\" width=\"18\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\" stroke=\"#3b6fd6\" stroke-linejoin=\"round\" stroke-width=\"1.8\"\u003e\u003c\/path\u003e\u003cpath d=\"M14 2v6h6\" stroke=\"#3b6fd6\" stroke-linejoin=\"round\" stroke-width=\"1.8\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003cspan style=\"display:flex;flex-direction:column;min-width:0;\"\u003e\u003cspan style=\"font-weight:600;color:#111827;\"\u003eManual\u003c\/span\u003e\u003cspan style=\"font-size:13px;color:#6b7280;\"\u003ePDF Document\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"color:#3b6fd6;font-weight:500;white-space:nowrap;\"\u003eOpen\u003c\/span\u003e\u003c\/a\u003e\u003c\/div\u003e","brand":"Victron Energy","offers":[{"title":"15 ft","offer_id":47125539750137,"sku":"IVV80009","price":30.6,"currency_code":"USD","in_stock":true},{"title":"32 ft","offer_id":47125539782905,"sku":"IVV80010","price":30.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/8538\/1625\/files\/Product-IVV80009-1.jpg?v=1784240208","url":"https:\/\/emarineinc.com\/products\/victron-ve-bus-bms-12-200-cable","provider":"eMarine","version":"1.0","type":"link"}
