Features: The M609 battery protections module features precise voltages monitoring, enabling timely detection of battery voltages levels. It incorporates safeguards against overcharging, deeply discharge, short circuits, and overcurrent. Reset procedure: Simultaneously press both buttons whilst the device is powered off. Upon powering on, the display will show ‘888’, indicating successful factory reset. The default protections threshold is set at 12V with a tolerance of about 2V. Automatic Disconnection: Upon reaching the preset voltages threshold, the module automatically disconnects the load to prevent deeply discharge and prolong battery use. Versatile Applications: The M609 voltages protections module is compatibles most battery types finds extensive use in wireless devices, power tools, electric vehicles, and similar applications.
