Smart BMS CL 12-100

The Victron Energy Smart BMS CL 12-100 is an all-in-one battery management system (BMS). It is specifically designed for Victron Smart lithium batteries (12.8 V) and 12 V systems equipped with an alternator, particularly in vehicles and boats. Its primary function is to protect and monitor each individual battery cell.

This BMS is specifically designed for Victron Smart 12.8 V lithium batteries. It provides protection and monitoring for each individual cell within these batteries.

Up to 20 Victron Smart 12.8 V lithium batteries can be connected in a single system managed by this BMS.

In a 12 V system, the Smart BMS CL 12-100 can handle a maximum energy storage capacity of 84 kWh by connecting up to 20 batteries.

The Alternator/Starter Batt+ port limits current and ensures unidirectional current flow from the alternator to the lithium battery. This allows safe connection of any 12 V alternator (and starter battery) to the lithium battery while protecting the alternator from overload and the lithium battery from excessive charging currents.

The Smart BMS CL 12-100 protects the alternator by electronically limiting the input current on the Alternator/Starter Batt+ port to approximately 90 % of the fuse rating. For example, with a 100 A fuse, the input current is limited to about 90 A. This limitation prevents the alternator from overheating and failing in case of prolonged operation at full power.

No, current flow is unidirectional. The Smart BMS CL 12-100 prevents current from flowing from the lithium battery to the starter battery, protecting the lithium battery from deep discharge.

The BMS monitors and protects each individual battery cell. It will disconnect the alternator, charging sources, or DC loads in the following cases:

Low or high battery cell voltageExcessive temperature

The pre-alarm output can be used to activate a relay, an LED, or an audible alarm. It emits a warning signal before the BMS disconnects the batteries from the system in case of imminent low cell voltage. The alarm triggers with a minimum delay of 30 seconds before the load-disconnect output is deactivated.

The Smart BMS CL 12-100 features electronic protection rated IP65. This means it is protected against dust and low-pressure water jets from all directions.

The dimensions of the Smart BMS CL 12-100 are 65 x 120 x 224 mm (height x width x depth). Its weight is 1.6 kg.

Monitoring, initial configuration, and diagnostics of the BMS are performed via Bluetooth using the VictronConnect application. This application allows you to view key parameters in real time.

'Instant Readout' is a feature in the VictronConnect app that allows real-time reading of the most critical BMS values without requiring a direct BMS connection. This simplifies quick diagnostics and provides greater range than standard Bluetooth connections.

Yes, it is designed to be safely connected to any 12 V alternator, thanks to its dedicated input which provides current limiting and protection against alternator overload.

This BMS was specifically designed for 12 V systems equipped with an alternator, such as those found in vehicles and boats.

No, the Smart BMS CL 12-100 is an all-in-one battery management system specifically designed for Victron Smart 12.8 V lithium batteries. It is not compatible with batteries from other brands.

The load disconnection output can be used to control DC loads with a remote on/off input, such as BatteryProtect devices, inverters, or DC-DC converters. It cuts the load in case of cell undervoltage risk to prevent deep discharge.

The load disconnect output can control the remote on/off port of various chargers, including the Phoenix Smart Charger IP43, a Cyrix-Li-Charge relay, or a Cyrix-Li-ct battery combiner. It allows the charge to be interrupted in case of cell overvoltage or excessive temperature.

During installation, it is imperative to comply with national safety regulations. The installation must be carried out only by qualified and trained installers. Before making any changes to connections, the system must be powered off and the absence of dangerous voltages must be verified. It is also crucial not to discharge a new lithium battery before it has been fully charged and to charge it only within the specified limits.
