The Victron SmallBMS with Pre-Alarm - BMS400100000 is an all-in-one battery management system (BMS) for batteries. Lithium Battery Smart from Victron Energy<\/a>. 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).<\/p>\n

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

Features of the Victron SmallBMS with pre-alarm - BMS400100000:<\/h2>\n

Load disconnect output<\/h3>\n
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.<\/div>\n
The load output can be used to control:<\/div>\n
- A high current relay or contactor.<\/div>\n
- 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).<\/div>\n
<\/div>\n

Pre-alarm output<\/h3>\n
Pre-alarm output is normally free-floating and goes high in case of imminent cell undervoltage (default 3.1V\/cell, adjustable at the battery between 2.85V and 3.15V per cell). Maximum current: 1A (without short-circuit protection).<\/div>\n
The minimum delay between pre-alarm and load disconnection is 30 seconds.<\/div>\n
<\/div>\n

Load disconnect output<\/h3>\n
Charger output is normally high and becomes free-floating in case of imminent cell overvoltage or overtemperature. Maximum current: 10mA.<\/div>\n
The charger output is not suitable for supplying an inductive load such as a relay coil.<\/div>\n
The charger output can be used to control:<\/div>\n
- Remote on\/off switching of a charger<\/div>\n
- One Cyrix-Li-Charge relay<\/div>\n
- One Cyrix-Li-ct battery combiner<\/div>\n
<\/div>\n

System on\/off input<\/h3>\n
The system's on\/off input controls both outputs. When it is off, both outputs are free so that loads and chargers are switched off.<\/div>\n
The on\/off input to the system consists of two terminals: Remote L and Remote H.<\/div>\n
Between L and H a remote on\/off switch or a relay contact can be connected.<\/div>\n
Alternatively, the H terminal can be switched to battery plus, or the L terminal can be switched to battery minus.<\/div>\n
<\/div>\n

Protects 12V, 24V and 48V systems<\/h3>\n
Operating voltage range: 8 to 70 V DC.<\/div>\n
<\/div>\n

LED indicators<\/h3>\n
Charge ON (blue): High charge output (cell voltage >2.8V, adjustable at the battery).
\nTemp or SBT (red): Free-floating charger output (due to too high (>50\u00b0C) or too low cell temperature (<5\u00b0C) or cell overvoltage).<\/div>\n
