The maximum allowable input voltage is 75V. Avoid overvoltage input or reverse polarity connection. To prevent battery backflow and damage, ensure the output voltage is always higher than the battery voltage, or connect a diode in series with the output positive pole. Ensure correct polarity when connecting the output terminal to the battery. This is a voltage reduction module, with maximum output voltage = input voltage × 0.95 - 1V.
