{"product_id":"victron-ve-bus-bms-v2","title":"Victron VE.Bus BMS V2","description":"\u003cp\u003eThe Victron VE.Bus BMS V2 is the next-generation Battery Management System designed to interface with and protect Victron Lithium Battery Smart (LiFePO₄) batteries in systems that include Victron inverters or inverter\/chargers with VE.Bus communication. Compatible with 12.8V and 25.6V Lithium Battery Smart batteries, it supports system voltages of 12V, 24V, and 48V, with a maximum of 20 batteries per system — enabling energy storage of up to 84 kWh in a 12V system and up to 102 kWh in a 24V or 48V system.\u003c\/p\u003e\n\u003cp\u003eThe VE.Bus BMS V2 continuously monitors each individual battery cell for overvoltage, undervoltage, overtemperature, and undertemperature conditions via BMS cables with M8 circular connectors. In multi-battery installations, the BMS cables of each battery are daisy-chained in series. Based on battery status, the BMS automatically generates pre-alarm signals, disables inverting via VE.Bus in the event of cell undervoltage, and disables charging via VE.Bus, VE.Direct, and VE.Can solar chargers (through a GX device) in the event of cell overvoltage or temperature faults.\u003c\/p\u003e\n\u003cp\u003eVE.Bus inverters and inverter\/chargers such as the MultiPlus and Quattro connect to the BMS via the dedicated MultiPlus\/Quattro RJ45 port using a standard UTP cable. A GX device, Digital Multi Control (DMC) panel, or VE.Bus Smart dongle can be connected to the Remote panel port for remote on\/off\/charger-only control of the inverter\/charger. A dedicated GX-Power output terminal keeps the GX device powered at all times, and an Aux-In terminal allows an external power supply to maintain GX operation even during a full system shutdown.\u003c\/p\u003e\n\u003cp\u003eRemote on\/off terminals allow a switch or relay contact to turn the entire system on or off, with the BMS supporting multiple wiring modes for flexible integration. Three LED indicators provide clear operational status — blue for normal operation, red for cell overvoltage or overtemperature, and blue for load disconnect active with healthy cell voltage.\u003c\/p\u003e\n\u003cp\u003eHoused in a compact matt-black ABS enclosure and rated IP20, the Victron VE.Bus BMS V2 is designed for reliable long-term operation in a wide range of off-grid, marine, RV, and renewable energy storage installations.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003ch4\u003eIndividual Cell Protection for Lithium Battery Smart Packs\u003c\/h4\u003e\n\u003cp\u003eThe VE.Bus BMS V2 monitors each individual cell within every connected Victron Lithium Battery Smart battery for overvoltage, undervoltage, overtemperature, and undertemperature conditions — providing comprehensive protection that goes beyond simple battery-level voltage monitoring.\u003c\/p\u003e\n\u003ch4\u003eAutomatic Load and Charge Disconnection\u003c\/h4\u003e\n\u003cp\u003eIn the event of a cell undervoltage fault, the BMS disables inverting via VE.Bus and signals the Load Disconnect output to shed DC loads. In the event of cell overvoltage or temperature faults, the BMS disables charging across VE.Bus inverter\/chargers, VE.Direct and VE.Can solar chargers via a GX device, and other chargers via the Charge Disconnect terminal.\u003c\/p\u003e\n\u003ch4\u003ePre-Alarm Warning Output\u003c\/h4\u003e\n\u003cp\u003eA dedicated pre-alarm output generates an early warning signal before an imminent cell undervoltage condition triggers a full load disconnect — allowing connected devices or an audible alarm to alert users in time to take corrective action.\u003c\/p\u003e\n\u003ch4\u003eVE.Bus Integration with MultiPlus and Quattro\u003c\/h4\u003e\n\u003cp\u003eConnects directly to Victron MultiPlus, Quattro, and VE.Bus inverters via two RJ45 sockets using a standard UTP cable, enabling precise charge and invert control through the VE.Bus communication protocol without additional interface hardware.\u003c\/p\u003e\n\u003ch4\u003eRemote Panel and GX Device Support\u003c\/h4\u003e\n\u003cp\u003eA dedicated Remote panel port allows connection of a Cerbo GX or other GX device, a Digital Multi Control panel, or a VE.Bus Smart dongle — individually or in combination — for full remote on\/off\/charger-only control of the VE.Bus inverter\/charger.\u003c\/p\u003e\n\u003ch4\u003eAuxiliary GX Power Input and Output\u003c\/h4\u003e\n\u003cp\u003eThe dedicated GX-Power output keeps a connected GX device powered continuously. The Aux-In terminal allows an external power supply to maintain GX device operation during system shutdown events, preserving VRM remote access even when the battery bank is offline.\u003c\/p\u003e\n\u003ch4\u003eSupports up to 20 Batteries — 12V, 24V, and 48V Systems\u003c\/h4\u003e\n\u003cp\u003eA maximum of 20 Victron Lithium Battery Smart batteries can be connected to a single VE.Bus BMS V2 in series, parallel, or series\/parallel configurations — supporting system voltages of 12V, 24V, or 48V and up to 102 kWh of total energy storage.\u003c\/p\u003e\n\u003ch4\u003eLED Status Indicators\u003c\/h4\u003e\n\u003cp\u003eThree onboard LEDs provide clear at-a-glance system status: a blue status LED flashes every 10 seconds during normal operation; a red LED indicates cell overvoltage or overtemperature; and a second blue LED confirms that the load disconnect output is active with cell voltages above 2.8V.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"product-spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e9-70 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Battery Voltages\u003c\/td\u003e\n\u003ctd\u003e12.8V and 25.6V (Victron Lithium Battery Smart)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Batteries per System\u003c\/td\u003e\n\u003ctd\u003e20 batteries (up to 102 kWh)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVE.Bus Communication Port\u003c\/td\u003e\n\u003ctd\u003e2 × RJ45 sockets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad Disconnect Output\u003c\/td\u003e\n\u003ctd\u003eSource current limit: 1A (normally high, floating on disconnect)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharge Disconnect Output\u003c\/td\u003e\n\u003ctd\u003eSource current limit: 10mA (normally high, floating on disconnect)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to +50°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e120 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (h × w × d)\u003c\/td\u003e\n\u003ctd\u003e23.8 × 94.5 × 105.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDatasheets and Manuals\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/upload\/documents\/Datasheet-VE-Bus-BMS-V2-EN.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/upload\/documents\/VE.Bus_BMS_V2\/111619-VE_Bus_BMS_V2_-_Manual-pdf-en.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47127242244345,"sku":"IVV50241","price":156.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/8538\/1625\/files\/Product-IVV50241-1.webp?v=1778934934","url":"https:\/\/emarineinc.com\/products\/victron-ve-bus-bms-v2","provider":"eMarine","version":"1.0","type":"link"}
