Victron Mini BMS - Battery Management Systems for 12 volt Lithium batteries

SKU: BMS400100000 $58.00 $49.30 You Save: 15%
A simple and low cost alternative to the VE.Bus BMS The miniBMS can replace the VE.Bus BMS in several applications. It is however not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers: it has no VE.Bus interface. The miniBMS is intended for use with Victron Smart LiFePo4 batteries with M8 circular connectors. The miniBMS has two outputs, similar to the VE.Bus BMS.

Load Disconnect output The Load output is normally high and becomes free floating in case of imminent cell under voltage. Maximum current: 1A. The Load output is not short-circuit protected. The Load output can be used to control: • A high current relay or contactor. • The remote on/off input of a Battery Protect, inverter or DC-DC converter or other loads. (a non-inverting or inverting on/off cable may be required, please consult the detailed manual on our website)

Charge disconnect output The Charger output is normally high and becomes free floating in case of imminent cell over voltage or over temperature. Maximum current: 10mA. The Charger output is not suitable to power an inductive load such as a relay coil. The Charger output can be used to control: • The remote on/off of a charger • A Cyrix-Li-Charge relay • A Cyrix-Li-ct Battery Combiner

System on/off input The system on/off input controls both outputs. When off, both outputs will be free floating so that loads and chargers are turned off. The System on/off consists of two terminals: Remote L and Remote H. A remote on/off switch or relay contact can be connected between L and H. Alternatively, terminal H can be switched to battery plus, or terminal L can be switched to battery minus.

Protects 12V, 24V and 48V systems Operating voltage range: 8 to 70V DC.

LED indicators • Load ON (blue): Load output high (cell voltage >2.8V, adjustable on the battery). • Temp or OVP (red): Charger output free floating (due to cell over temperature (>50°C), cell under temperature (<5 °C) or cell over voltage).
