For first-time use or after shutdown, connect the battery to a LiFePO4 charger or an MPPT (with lithium activation) for 3-10 seconds. This will power on the battery and enable Bluetooth. If you don’t have a compatible charger, please make sure to purchase a charger or MPPT together with the Bluetooth battery.
All LiTime chargers and MPPTs come with lithium battery activation functionality.
Note: To ensure safe transportation, Bluetooth batteries with ＜100Ah amp-hour capacity are shipped in a shutdown state.

The battery details page shows the following information:

1. Real-Time Data: Remaining battery capacity, power, current, voltage, cell temperature, and battery life cycles.
2. Battery Status Monitoring: The app monitors the battery’s working state, including standby, charging, discharging. During charging or discharging, the estimated time for completion is displayed. During discharge, power and current values are shown with a negative sign to indicate the discharge state.

The Bluetooth operation interface includes the following controls:

1. Bluetooth Button and Custom Name Button: Allows users to manage Bluetooth connections and set custom device names.

2. Control Buttons:
Discharge Switch: Controls whether the battery supplies power to the load, with an animated demonstration.
Power Off Button: Powers off the battery and disconnecting Bluetooth simultaneously, with animated effects.
Note: This button is disabled when the battery is charging.
Remove Button: Allows users to remove the device from the app.

Yes, it can.
When accessing the battery system details page, the app automatically collects and summarizes information from all batteries within the system. It displays comprehensive system data, including system voltage, current, power, and remaining battery system capacity in real time.

Yes, it can.

During the data retrieval process, the status of each individual battery within the system is displayed in the upper right corner of the battery card with the following indicators:

Green Dot: Indicates that the battery status and data are normal. You can click on the battery card to view detailed information about that specific battery.
Red/Orange Dot: Indicates an abnormal battery status, but data can still be retrieved. Clicking on the battery card provides detailed information about the issue.
Exclamation Mark: Indicates an issue with retrieving battery information, possibly due to Bluetooth connection problems. You can click on the battery card for troubleshooting guidance.

Yes, it will.

If the Bluetooth connection is lost due to distance (approximately 10 meters under ideal conditions, though actual range may vary depending on the environment), the app will attempt to reconnect automatically when the phone moves back within communication range.

Manual reconnection is needed in the following situations:

Battery Shutdown: When the battery is out of power or in undervoltage protection mode. In this case, plug in the charger to activate and restart the battery.
App Closed in Background: If the app is closed in the phone's background, you will need to reopen it to reconnect.
Bluetooth Disabled: If the phone's Bluetooth function is turned off, the connection between the app and the device will be interrupted.
Other Bluetooth Disconnections: If Bluetooth disconnects unexpectedly for reasons other than those listed above, please contact LiTime Service for support.

No, you cannot.

Once the account is deleted, all information associated with it, including connected device data, will be permanently lost. You will need to create a new account and reconnect the Bluetooth devices from scratch.

Yes, you can.

When there is no internet connection, a screen prompting you to enter the SN code (visible on the battery) will appear. Enter the SN code to complete the device addition process.
