The Smart BMS CL 12-100 is an all-in-one battery management (BMS) system for Victron Lithium Battery Smart 12,8 V batteries available with a nominal voltage of 12.8 V in various capacities. This is the safest of the mainstream lithium battery types. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84 kWh in a 12 V system. It has been specifically designed for 12 V systems with a 12 V alternator such as in vehicles and boats.
A dedicated alternator input provides current limiting and one-way traffic from the alternator into the battery, this so any size 12 V alternator (and starter battery) can be safely connected to the lithium battery. The Charge Current Limiter protects the alternator against overload. It 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/high battery cell voltage or high temperature.

Features
• Alternator/Starter Batt+ port alternator and battery protection: The input current on the Alternator/Starter Batt+ port is electronically limited to approximately 90 % of the fuse rating.
A 100 A fuse, for example, will therefore limit the input current to approximately 90 A and protects the lithium battery against excessive charge current and the alternator against
overload (most 12 V alternators will overheat and fail if running at maximum output during more than 5 minutes).
• Remote on/off terminal: Use it to interrupt charging via the Alternator port while keeping the BMS functionality active, or as an on/off switch to turn off the system completely.
• Load and Charge disconnect output1): The Smart BMS CL 12-100 monitors and protects each individual battery cell within the battery and will disconnect the alternator, charge sources or
DC loads in case of low/high battery cell voltage or high temperature.
• Pre-Alarm output: Can be used to drive a relay, LED or Buzzer to issue a warning signal before the BMS disconnects the batteries from the system.
• Bluetooth for monitoring and configuration via the VictronConnect app and with Instant Readout the possibility to read out the most important values in real time without the need to connect to the BMS, which enables diagnostics at a glance.
