Product information

The Victron SmallBMS with pre-alarm - BMS400100000 is an all-in-one battery management system (BMS) for batteries. Lithium Battery Smart by Victron Energy. These are lithium iron phosphate (LiFePO4) batteries available in 12.8 V or 25.6 V and in different capacities. They can be connected in series, parallel and series/parallel, so that a battery bank can be assembled for 12 V, 24 V or 48 V system voltages. The maximum number of batteries in a system is 20, which means a maximum energy storage of 84 kWh in a 12 V system and up to 102 kWh in a 24 V system1) and 48 V.1).

The smallBMS is a simple and cost-effective alternative to the VE.Bus BMS, but it does not have a VE.Bus interface, therefore it is not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers.

Features of the Victron SmallBMS with pre-alarm - BMS400100000:

Load disconnect output

Load output is normally high and becomes floating in case of cell undervoltage (default 2.8V/cell, adjustable at the battery between 2.6V and 2.8V per cell). Maximum current: 1A. The load output is not protected against short circuits.

The load output can be used to control:

- A high current relay or contactor.

- Remote on/off input from a Battery Protect, inverter or DC-DC converter or other loads (a non-inverter or inverter on/off cable may be required, see detailed manual on our website).

Pre-alarm output

Pre-alarm output is normally free floating and becomes high in case of imminent cell undervoltage (default 3.1V/cell, adjustable on battery between 2.85V and 3.15V per cell). Maximum current: 1A (without short-circuit protection).

The minimum delay between pre-alarm and load disconnection is 30 seconds.

Load disconnect output

Charger output is normally high and becomes free-floating in case of imminent cell overvoltage or overtemperature. Maximum current: 10mA.

The charger output is not suitable for powering an inductive load such as a relay coil.

The charger output can be used to control:

- Remote switching on and off of a charger

- One Cyrix-Li-Charge relay

- One Cyrix-Li-ct battery combiner

System on/off input

The on/off input of the system controls both outputs. When off, both outputs are free so that loads and chargers are turned off.

The on/off input of the system consists of two terminals: Remote L and Remote H.

Between L and H a remote on/off switch or relay contact can be connected.

Alternatively, the H terminal can be switched to battery plus, or the L terminal can be switched to battery minus.

Protects 12V, 24V and 48V systems

Operating voltage range: 8 to 70 V DC.

LED indicators

Charge ON (blue): High charge output (cell voltage >2.8V, adjustable on the battery).
Temp or SBT (red): Charger output in free float (due to too high (>50°C) or too low cell temperature (<5°C) or cell overvoltage).
