the battery voltage returns and burns the power supply. 1. Cannot input AC power, and less 220V mains power. 2. The maximum allowed input voltage is 75V and no overvoltage input or reverse polarity connection is allowed. 3. The outlet can not be fully guaranteed to prevent backflow. When connecting the battery, make sure the output voltage of the power module is as long as the battery voltage, or connect a diode in series with the positive terminal of the output to avoid one-way driving. Precautions: 4. When connecting the output terminal to the battery, be careful not to reverse the positive and negative. 5. The product is step-down module, the maximum output voltage = input voltage * 0.95-1V., Manufacturer: Bumdenuu
