    Description

    The s-BMS consists of a BMCU (Battery Management Control Unit) master board. The master board communicates with up to 32 Local Monitoring Units (LMU), featuring up to 1000V applications. The LMU monitors individual and total voltages of 3-8 cells in series and features 2 temperature sensors.

    The s-BMS can be configured through the licensed s-BMS PRO software, which enables the battery integrator to create a unique battery design and tailor it specifically for their needs.
