Important Notes

• Do not input AC power or connect to 220V mains power.
• 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.
