Note:
- Battery is not included.
- If you need a longer shielded wire, please contact customer service.
- The coulomb meter should not be exposed to the sun for a long time, nor can it be exposed to extreme conditions below -20℃ and above 60℃ for a long time, otherwise it will shorten the service life of the LCD screen.
- Other items pictured are not included in the package, for demonstration purposes only. Thank you for your understanding!

Using Steps:
1. Wire and check the current: complete the connection as shown in the figure, and power on the coulomb counter. The screen should display information such as battery voltage, current and capacity percentage. If there is no display on the screen, turn off the power and check if the connection is correct. Then discharge or charge the battery and check whether the displayed current value is consistent with the actual current value. If the error is large, please check whether the wiring is correct.

2. Capacity reset: the percentage and capacity displayed on the screen when it is first used are not the actual values of current battery, and the displayed capacity must be reset. After emptying the battery, press and hold the button  on the back for 3 seconds to zero capacity, or fully charge the battery and press and hold the button  on the back for 3 seconds to fully capacity. The coulometer can be used normally, and this step is not necessary in the later stage.

3. Detection and reset of the actual battery capacity: If the display capacity of the coulomb meter does not match the actual capacity during use, please check the actual battery capacity and reset the capacity. After the battery is discharged, press and hold the button  for 3 seconds to reset the capacity to zero, and then enter the setting interface to set the preset capacity value as large as possible. Then charge the battery pack. After fully charged, the screen display value is the actual battery capacity. Finally, modify the preset capacity value to the displayed value.
