Step 2

Bluetooth Connection

Please turn on Bluetooth on your mobile phone, open the BatteMax app, and go to the “Bluetooth” page. Search for the SN of the battery for which you need technical support. The battery SN can usually be found on the top cover of the battery. If the SN cannot be identified, please note that our product SNs follow this format: they start with the letter J and are 19–21 characters long.

Tap the button next to the SN. When the button turns orange , it indicates that the battery has been successfully connected to our app.

Step 3

Screenshot

Tap “ Dashboard ” at the bottom of the app and take a screenshot of this page. The screenshot must include the Summary Section , Protection Section , Temperature , and Cell List Section .

Please make sure the screenshot captures all content on this page, including the complete Cell List .

Step 4

Share Data

Tap “About” at the bottom of the app, then select “Shared Data.” This process may take a few minutes. After the data is successfully shared, a “Success” message will appear on the screen.

Please also take a screenshot showing the “ Hardware Version ” and “ Firmware Version ”.

If the data CANNOT be shared, or if the “ Hardware Version ” and “ Firmware Version ” fields show no data, please close the app from the background and reconnect to the battery via Bluetooth.

Great!
