The smallBMS can replace the VE.Bus BMS V2 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 smallBMS is intended for use with Victron Smart LiFePo4 batteries with M8 circular connectors.

The smallBMS has two outputs, similar to the VE.Bus BMS V2.

The VE.Bus BMS protects each individual cell of a Victron lithium-iron-phosphate (LiFePO4 or LFP) battery.
Each individual cell of a LiFePO4 battery must be protected against over voltage, under voltage and over temperature.
Victron LiFePO4 batteries have integrated Balancing, Temperature and Voltage control (acronym: BTV) and connect to the VE.Bus BMS with two M8 circular connector cord sets.
The BTVs of several batteries can be daisy chained. Please see our LiFePO4 battery documentation for details.

The BMS will:

Shut down or disconnect loads in case of imminent cell under voltage
Reduce charge current in case of imminent cell overvoltage or over temperature (VE.Bus products only, see below)
Shut down or disconnect battery chargers in case of imminent cell overvoltage or over temperature

The Smart BMS 12/200 is an all-in-one Battery Management system for Victron Lithium-Iron-Phosphate (LiFePO4) Smart Batteries. It has been specifically designed for 12V systems with a 12V alternator such as in vehicles and boats.

It combines a Current Limiter, Battery Combiner and Battery Protector in a robust and compact solution and lets you safely connect any size 12V alternator (and starter battery), loads and chargers to Smart Lithium batteries.

The Smart BMS 12/200 monitors and protects each individual battery cell within the battery (or battery bank) and will disconnect the alternator, charge sources or DC loads in case of low battery cell voltage, high battery cell voltage or over temperature.

The dedicated alternator connection provides current limiting and one-way traffic from the alternator into the battery, this so any size alternator (and starter battery) can be safely connected to the Smart Lithium battery (or battery bank) and the starter battery is protected from excessive discharge.

The BMS is equipped with Bluetooth for monitoring and configuration, a remote on/off connector, to turn the BMS (and the system) off via a remote switch and a pre-alarm contact, to give a warning signal before the BMS will disconnect the batteries from the system.

The Smart BMS CL 12/100 is a Battery Management system for Victron lithium-iron-phosphate (LiFePO4) Smart Batteries. It has been specifically designed for 12V systems with a 12V alternator.

The BMS CL 12/100 monitors and protects each individual battery cell within the battery (or battery bank) and will disconnect the alternator, charge sources or DC loads in case of low battery voltage, high battery voltage or over temperature.

The dedicated alternator input provides current limiting and one-way traffic from the alternator into the battery, this so any size alternator (and start battery) can be safely connected to the Smart Lithium battery or batteries.

The BMS is also equipped with a remote on/off connector, to turn the BMS (and the system) off via a remote switch, and a pre-alarm contact, to give a warning signal before the BMS will disconnect the batteries from the system.

The Battery Balancer equalizes the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24V battery system increases to more than 27V, 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 1A 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 48V battery bank can be balanced with three Battery Balancers.

Replacing the active material of the negative plate by a lead carbon composite potentially reduces sulfation and improves charge acceptance of the negative plate.

The advantages of lead carbon therefore are:

Less sulfation in case of partial state-of-charge operation.
Lower charge voltage and therefore higher efficiency and less corrosion of the positive plate.
And the overall result is improved cycle life.
