Features: brand new and high quality 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.
