Actual case

BMS Feature

 Long lifespan with deep cycles

High performance safety-the energy storage module’s usage can be controlled safety by monitoring the status of the internal batteries and communicating the outcome to a linked external battery management system or controlling unit


A built-in self-monitoring function detects any abnormality within the module itself

High Scalability- capacity can be customized for different applications by connecting multiple modules either in parallel
