Low Voltage Battery Management System

We offer 2 low voltage BMS solutions to meet a wide variety of industries. The LV-6SBMS-100 can be used in 4S/5S/6S configurations for 12V-30V applications while the LV-16SBMS-100 can be used in 8S – 16S configurations for 24V-80V applications. Stop “phantom drain” when your battery is not in use with Pre-Charge Plus, which eliminates current draw when the system is not use. Pre-Charge Plus also has the ability to detect current flow and instantly wake-up and continue operation. With a wide range of control options and connectivity, the LV-BMS-100 suite is designed for a wide array of use cases, such as auxiliary power, RV, work trucks, marine, aerial applications and more. Included with all our BMS comes our E1 Battery Assistant to monitor, customize and log data with ease, simply connect over USB and see live battery data.
