Features:
【Product parameters】XH-M609 battery over-discharge protection module has an input voltage of DC6V-30V, voltage control accuracy of 0.1V, power consumption <1.5W, product size 57*42*19mm/2.24*1.65*0.75inch, including 2pcs.
【Battery protection】The XH-M609 module has an accurate voltage monitoring function, which can detect the battery voltage in time, with overcharge, overdischarge, short circuit and overcurrent protection. When the battery is under-voltage or under-charged, it will automatically disconnect to prevent damage caused by over-discharging the battery.
【Reset operation】When the power is off, press and hold both buttons at the same time, then power on, the screen will show "888" to indicate the successful restoration of factory settings, the factory set protection value is 12V, the difference is 2V.
【Automatic disconnection】When the battery voltage reaches the set value, the module automatically disconnects the load to avoid over-discharging the battery and extend the battery life.
【Multiple applications】The XH-M609 voltage protection module is suitable for all types of batteries, including lithium and lead-acid batteries, which is widely used in wireless devices, power tools, electric vehicles and other applications.
