Victron miniBMS
A simple and low cost alternative to the VE.Bus BMS
The miniBMS / smallBMS can replace the VE.Bus BMS in several applications. It is however not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers as it has no VE.Bus interface. The smallBMS is intended for use with Victron Smart LiFePo4 batteries with M8 circular connectors. The miniBMS/smallBMS has three outputs, similar to the VE.Bus BMS.
Load Disconnect output
The Load output is normally high and becomes free floating in case of cell under voltage (default 2,8V/cell, adjustable on the battery between 2,6V and 2,8V per cell). 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.
Pre-alarm output
The pre-alarm output is normally free floating and becomes high in case of imminent cell under voltage (default 3,1V/cell, adjustable on the battery between 2,85V and 3,15V per cell). Maximum current: 1A (not short circuit protected). The minimum delay between pre-alarm and load disconnect is 30 seconds.
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
The miniBMS/smallBMS has na operating voltage range of 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)

Victron Battery Balancer
The service life of an expensive battery bank can be substantially shortened due to state of charge unbalance. One battery with a slightly higher internal leakage current in a 24 V or 48 V bank of several series/parallel connected batteries will cause under-charge of that battery and parallel connected batteries, and over-charge of the series-connected batteries. Moreover, when new cells or batteries are connected in series, they should all have the same initial state of charge. Small differences will be ironed out during absorption or equalize charging, but large differences will result in damage due to excessive gassing (caused by overcharging) of the batteries with the higher initial state of charge and sulphating (caused by undercharging) of the batteries with the lower initial state of charge.
The Battery Balancer equalizes the state of charge of two series-connected 12 V batteries, or of several parallel strings of series-connected batteries. When the charge voltage of a 24 V battery system increases to more than 27 V, the Battery Balancer will turn on and compare the voltage over the two series-connected batteries. The Battery Balancer will draw a current of up to 1 A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge. If needed, several balancers can be paralleled. A 48 V battery bank can be balanced with three Battery Balancers.

Victron BatteryProtect 12/24V-65A
The Battery Protect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.
BatteryProtect 65A Features:
12/24V Auto Ranging
The BatteryProtect automatically detects system voltageProgramming made easy
The BatteryProtect can be set to engage / disengage at several different voltages. the seven segment display will indicate which setting has been chosen.A special setting for Li-ion batteries
In this mode the BatteryProtect can be controlled by the VE.Bus BMS. Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion
battery. See connection diagram in the manual.Ultra low current consumption
Uses only 1.5ma when on and when off or due to low voltage shutdown uses only 0.6ma. This is important in case of Li-ion batteries, especially after low voltage shutdownOver voltage protection
To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16V (12V setting) and 32V (24V setting)Ignition proof
The unit doesn’t use relays but MOSFET switches instead, and therefore no sparks.Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.Delayed load disconnect and delayed reconnect
The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.Product Video – Introduction to the Victron Energy BatteryProtect
