APP Usage Examples

Android / iOS

Search for the download page and click the [Install] button to install, as shown in Figure 1.

1. After installation is completed, open the device name interface, select the name of the battery pack that needs to be connected, and click on it, as shown in Figure 2
2. When entering the app for the first time, a pop-up window will prompt you to obtain Bluetooth usage permission. Click on the settings and select agree to use, as shown in Figure
3. Note: When connecting Bluetooth, please confirm that the Bluetooth and GPS switches on your phone are turned on first, otherwise you will not be able to connect.

Following a successful Bluetooth connection, you can click the [Status Display] button at the bottom left of the main interface to switch between diverse display interfaces and learn about the detailed data of the battery pack. The following data can be viewed, as depicted in Figure 4.

1. Display the battery level and percentage, enabling users to better grasp the real-time battery level.
2. Present the charging and discharging switches.
3. Exhibit the total voltage of the battery.
4. Reveal the magnitude of the charging and discharging current.
5. Display the power size.
6. Present the number of battery pack cycles.
7. Display battery status, ambient temperature, MOS temperature, first group cell temperature, and second group cell temperature.
8. Display the voltage details in multiple series of battery cells, encompassing voltage difference, average voltage, minimum voltage, maximum voltage, and voltage difference for each series of battery cells.
9. Present alarm information and set parameters
10. Set parameters.

* Unauthorized alteration of the parameters of the BMS board may cause abnormal operation of the battery and affect the product warranty, lf necessary, please contact the customer service to obtain the password.
