Sapphire Battery Bluetooth
Connect to a compatible Bluetooth-equipped Sapphire LiFePO₄ battery to view live pack voltage, current, state of charge, cell information, temperature and BMS status.
Select the iPhone or Android version on JBD's download page. No account required to view basic battery information.
Getting started
The essentials, without the extra detail. For screenshots and step-by-step button guidance, see Detailed Setup Guide below.
Use the download button above to install the JBD Battery App for your phone.
Turn on Bluetooth and grant the app the permissions it requests. Stay near your battery.
Open the app and create an account, or select Use as Guest to skip login. Connect using Bluetooth search or a compatible battery connection QR code.
See charge level, battery voltage and current. Individual cell voltages are not available in Guest mode.
Visual walkthrough
New to the app? Follow the screens below. Button positions may change slightly between app versions and Android/iPhone.
On the first screen, choose Use as Guest to skip account registration and begin basic battery monitoring, or log in if you have an account.
You can view key battery information, such as state of charge, total voltage and current. Individual cell voltages are not available in Guest mode.
There are two ways to find your battery in the JBD app. Use whichever method is available for your battery.
METHOD A · RECOMMENDED
Tap the Bluetooth search button in the app, then select your battery from the nearby devices list. If multiple batteries appear, compare their Bluetooth MAC addresses against the battery label, when available.
METHOD B · IF PROVIDED
If your battery includes a Bluetooth connection QR code, tap the app's camera/scan icon and scan the code.
Some QR codes are download links. If scanning opens the app download website or doesn't connect to your battery, use Method A: Bluetooth Search instead.
Connect inside the JBD app, not through your phone's normal Bluetooth pairing settings.
In Guest mode, view essential battery statistics including charge percentage, voltage and current. To access individual cell voltages, use a supported logged-in view instead.
These are real examples of the two connected screens.
If your battery doesn't appear, check Bluetooth permissions, move your phone closer, and make sure another phone isn't already connected. Some older Sapphire batteries may use the XiaoXiangElectric app instead.
