Step 1: Pull the buckle and open the lid of the battery box.
Step 2: Place the battery in the battery box.
Step 3: Attach the eyelets from the battery box lid to the corresponding positive and negative
terminals on the battery. Make sure connections are fastened and tight.
Step 4: Close the lid and make sure the buckle is latched.
Long press the ON switch for 3 seconds to check the reading of the battery power and activate the port
/plug/socket.
Connect the device to the port/plug/socket and charging will begin.
Note:
① For a rechargeable battery, a solar panel (with PWM/MPPT controller) /external battery can be
connected to the Anderson plug to charge the battery.
② Please note that the red Anderson plug is for power input only. It is controlled by the voltage
instead of the switch.
When the voltage of the battery in the box is below 8V, it will not be charged with external power supply.
Please make sure the voltage of external power supply is higher than that of the battery in the box.
Otherwise, the battery in the box will reversely charge external power supply via the red Anderson plug.
Only when the voltage of external power supply is above 13V, it will charge the battery in the box.
When the voltage of external power supply decreases to 12.5V, charging will stop after 10 seconds.
If the voltage is below 10V, voltmeter display will flicker (on for 1s and off for 1s repeatedly)
and there will be no power output after 10s.
Switch must be long pressed for 3 seconds to be turned on or off.
Please keep the inner of the box clean and dry.
Please cover USB ports and cigarette lighter sockets with rubber plugs to prevent potential damage.
Always keep the external terminals clean.
