Victron Energy smallBMS NG

The Victron small MS NG provides essential protection and monitoring for Victron Lithium NG battery systems. It supports 12V, 24V and 48V battery banks and allows compatible Lithium NG batteries to be connected in series, parallel or a combination of both. Built-in Bluetooth enables wireless configuration, monitoring and firmware updates through the Victron Connect app. Battery state of charge, temperature, warnings and alarms can be viewed directly without installing a separate Smart Shunt. The small BMS NG controls compatible chargers and loads through dedicated Charge Disconnect and Load Disconnect outputs. Its pre-alarm output can activate an external LED, buzzer or suitable relay before loads are disconnected because of low cell voltage. This model is ideal for installations that do not require VE Bus communication.Important: The small BMS NG is only compatible with Victron Lithium NG batteries. It is not compatible with Victron Lithium Battery Smart models and must not be used to control VE.Bus inverter/chargers such as the Multi Plus or Quattro.Key FeaturesDesigned exclusively for Victron Lithium NG batteriesSuitable for 12V, 24V and 48V systemsBuilt-in Bluetooth Smart connectivityMonitoring and configuration through Victron ConnectDisplays state of charge, battery temperature, warnings and alarmsConfigurable discharge floorLoad Disconnect output to prevent excessive dischargeCharge Disconnect output to prevent overchargingPre-alarm output for an LED, buzzer or suitable relayRemote on/off connectionBluetooth status and warning indicator LEDsCompact and straightforward installationNo separate Smart Shunt required for battery monitoringVictron five-year standard warrantyTechnical SpecificationsSpecificationDetailsProduct codeBMS400100300EAN8719076063537Operating voltage870V DCSupported system voltages12V, 24V and 48VCompatible batteriesVictron Lithium NG onlyBluetoothBuilt-inLoad Disconnect outputMaximum 1ACharge Disconnect outputMaximum 500mAPre-alarm outputMaximum 500mACurrent consumption remote on3mACurrent consumption remote off1.2mAOperating temperature-20C to +50CMaximum humidity95%, non-condensingProtection ratingIP20EnclosureMatt black ABSDimensions106 42 23mmWeight0.1kgCompatibility NoticeThe small BMS NG does not include a VE.
