Features: Five modes to use as a charger. Please adjust the voltage and charge according to the above five kinds of batteries. The rated voltage is the voltage of the corresponding battery that the charger needs to adjust; the full voltage is the voltage after the battery is fully , and the light will automatically turn on after the battery is fully . Use as a power adapter. You must turn on the power and adjust the voltage and current before connecting to the device. Multifunctional digital display power supply: adjustable voltage and current. With adjustable voltage 3V-60V and adjustable current 0.5-8A 150W. Finally press the button to confirm and start to exit. Use it as a power adapter. Please load your device wattage must be at least 30% less than the power supply. For example, your device usually uses 48V2.5A, This adapter must be set to 48v3a before connecting to the device. Steps to use the charger: Connect the power supply, and then connect the battery. Press the mode to select the corresponding battery type. (Caution: Selecting the wrong type of battery for charging may have the risk of burning and exploding) Press Voltage+/- to select the corresponding rated battery voltage. (Note: Selecting the wrong battery voltage for charging may result in a fire and explosion hazard) Press current +/- to select charging current. Usually choose 0.2c or choose the charging current according to the battery specification. Press OK to start charging, the red light is on. (Other key functions are invalid while charging, but only stop is valid if there is an error LED) When fully , it will automatically stop charging and display -full-. It has the function of preventing reverse battery connection. After the battery is reversely connected, the red and green charging indicators flash at the same time, and the charging is invalid.The lead-acid battery has an automatic detection function, selects the wrong voltage and does not charge, and displays -Err-.
