6. Maintenance
Regular monitoring and occasional checks ensure the longevity and optimal performance of your battery system and BMS.
- Regular Monitoring: Periodically check battery parameters via the Bluetooth app to ensure all values are within normal operating ranges.
- Connection Checks: Ensure all wiring connections remain secure and free from corrosion.
- Environmental Conditions: Operate the BMS and battery within recommended temperature ranges to prevent thermal stress.
7. Troubleshooting
If you encounter issues with your DALY BMS, consider the following troubleshooting steps:
- No Power/No Communication: Verify all wiring connections, especially the main power leads and the sampling cable. Ensure the Bluetooth module is properly seated.
- App Not Connecting: Confirm Bluetooth is enabled on your device and the BMS is powered on. Try restarting the app or your device.
- Unexpected Shutdowns: Check the app for any active protection notifications (e.g., over-discharge, over-current, high/low temperature). Address the root cause of the protection event.
- Inaccurate Readings: If the app displays unusual voltage or current readings, cross-reference with a reliable multimeter. Ensure the sampling cable is correctly connected to each cell.
- Mismatched BMS: Ensure the BMS current rating is appropriate for your application. Using an undersized BMS can lead to damage. Refer to the guidance in Image 4.1 for selecting the correct amperage.
For persistent issues, consult the detailed troubleshooting section in the complete manual or contact DALY customer support.
