Specific information: The power supply voltage is DC 12V-36V, and the output voltage is equal to the power supply voltage. This voltage protection module can control the voltage within 0.1V.<br /> Main functions: This digital low-voltage protector is functional and includes a variety of functions, including overcharge protection, overdischarge protection, short circuit protection, and overcurrent protection.<br /> Versatile: These disconnect over-discharge protection modules are suitable for all kinds of batteries and lithium batteries, and have a wide range of applications. When the battery is under voltage or insufficient, it will automatically disconnect.<br /> LED screen display: The digital LED screen display design allows you to easily read the output voltage and set parameters, and the voltage can be set arbitrarily within the range of 12-36V.<br /> Battery discharge protection: When the battery voltage reaches the set voltage, the over-discharge protection module will automatically disconnect the load to avoid battery over-discharge and prolong battery life.
