5. Installation Guide
Careful installation is critical for the proper functioning and safety of your battery system. Follow these steps precisely.
5.1 Wiring Diagram

5.2 Wiring Steps
- Preparation: Before connecting any wires, ensure the battery pack is fully discharged or at a safe voltage level. Important: Disconnect the white end of the balance wires and the BMS connection port before welding the black and red balance wires to the battery pack.
- Connect B- Wire: Connect the thick black wire (B-) from the BMS to the total negative pole of your battery pack.
- Connect P- Wire: Connect the thick blue wire (P-) from the BMS to the negative terminal of your load (motor) and charger.
- Connect Balance Wires: Connect the balance wires to each cell of the battery pack, starting from B0 (negative terminal of the first cell) up to B16 (positive terminal of the last cell). Ensure the order is correct.
- Connect NTC Sensor: Attach the NTC temperature sensor to a central cell or location within the battery pack to monitor temperature.
- Connect Communication Modules: Plug in the Bluetooth module or UART cable into their respective ports on the BMS.
- Final Check: Double-check all connections for correctness and security before applying power.
5.3 Initial Activation
After confirming all wiring is correct, activate the BMS using one of the following methods:
- Method 1: Press the activation button on the BMS board.
- Method 2: Connect the charger to the battery pack. The charging process will activate the BMS.
The initial password for the Smart APP is 123456. The BMS protection parameters (Li-ion, LiFePO4) have default values. The capacity of the battery pack needs to be set according to the actual capacity (Ah) of the battery pack. If the capacity Ah is not set correctly, the percentage of remaining power will be inaccurate. Other parameters can also be set to your needs.
6. Operation and Data Monitoring
The DALY Smart BMS allows for real-time monitoring and parameter adjustment via a dedicated smartphone application or PC software.
6.1 Bluetooth App Connection

- Ensure the Bluetooth module is correctly connected to the BMS.
- Download the DALY Smart BMS application from your smartphone's app store.
- Enable Bluetooth on your smartphone and open the DALY BMS app.
- The app will scan for available BMS devices. Select your BMS from the list.
- Enter the default password (123456) if prompted.
- Once connected, you can view real-time battery data and adjust parameters as needed.
6.2 UART Communication and PC Software

7. Maintenance Guidelines
Regular maintenance helps ensure the longevity and optimal performance of your DALY Smart BMS.
- Visual Inspection: Periodically inspect the BMS and all wiring for any signs of damage, corrosion, or loose connections.
- Cleaning: Keep the BMS clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Temperature Monitoring: Regularly check the battery and BMS temperature, especially during charging and discharging cycles, to ensure they remain within safe operating limits.
- Firmware Updates: Check the official DALY website or app for any available firmware updates for the BMS to ensure you have the latest features and bug fixes.
8. Troubleshooting Common Issues
If you encounter issues with your DALY Smart BMS, refer to the following troubleshooting steps:
- BMS Not Activating: Ensure all wiring is correct, especially the B- and P- connections. Try activating the BMS by pressing the activation button or connecting a charger.
- Bluetooth Connection Failure: Verify the Bluetooth module is securely connected to the BMS. Ensure Bluetooth is enabled on your smartphone and the app has necessary permissions. Try restarting the app or your phone.
- UART/PC Software Not Connecting: Check the UART cable connection to both the BMS and the computer. Ensure the correct COM port is selected in the PC software. Reinstall the PC software or drivers if necessary.
- Protection Triggered (Overcurrent, Overvoltage, Undervoltage): The BMS will trigger protection if battery parameters exceed safe limits. Check the battery voltage, current draw, and individual cell voltages. Reduce the load or adjust charging parameters if necessary.
- Inaccurate State of Charge (SOC): Ensure the battery pack's actual capacity (Ah) is correctly set in the BMS parameters via the app or PC software.
