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.

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 our 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
