Smart BMS CL 12/100 f/Victron LIFEPO4 Batteries 12VDC OnlyThe 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, 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 the 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.Please contact your dealer for any returns, repairs or support issues related to this product.
