This is a under-voltage switch module used to turn off the power of load in the event of the voltage dropping below a set value
When the battery voltage increases to a set value, the module will automatically turn on load again
Designed with a LED indicator to show if load is cut off or turned on
Both turn-off and turn-on voltage value can be adjusted by simply adjusting potentiometer
This protection board will help you to protect battery from over-discharging and prolong battery life
