The Smart BMS CL 12/100 is a specialized Battery Management System crafted for managing Victron lithium-iron-phosphate (LiFePO4) Smart Batteries in 12V systems, particularly those with a 12V alternator. This system is engineered to ensure the safety and longevity of each battery cell within a single battery or a battery bank. It accomplishes this by constantly monitoring for conditions such as low or high battery voltage, or excessive temperature, and in response, can disconnect the alternator, charging sources, or DC loads to prevent damage.

A unique feature of this BMS is its dedicated alternator input, designed to regulate the current and ensure that it flows only from the alternator to the battery. This functionality allows for the safe connection of any size of alternator (along with the start battery) to the Smart Lithium battery or battery bank, safeguarding both the battery and the alternator from potential harm due to overcharging or excessive load.

Furthermore, the Smart BMS CL 12/100 is outfitted with a remote on/off connector. This feature permits users to remotely deactivate the BMS and the connected system using a switch, offering added convenience and control over the system’s operation. Additionally, a pre-alarm contact is incorporated to emit a warning signal in advance of the system disconnecting the batteries. This early alert system provides users with a crucial window to take preventive actions if necessary, enhancing the overall safety and reliability of the battery management system.

Victron’s range of Battery Management Systems (BMS) is meticulously engineered to complement their Lithium Smart Battery series (12.8 V & 25.6 V), ensuring optimal performance and safety across various applications. Each model boasts specific features tailored to meet diverse system requirements, highlighting Victron’s commitment to versatility and reliability in energy management solutions.
