Victron Smart BMS CL 12-100

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 generator.

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

The dedicated generator input provides current limiting and one-way traffic from the generator into the battery, this so any size generator (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.
