- Step 1: Solder Sampling Cables. The first black cable in the sampling cable set connects to the negative terminal of the battery (B-). Subsequent red cables connect to the positive terminal of the first string, then the second string, and so on, until all cell positive terminals are connected.
- Step 2: Check Cables. After connecting the cables, use a multimeter to measure the voltage between two adjacent cells, starting from the header. Ensure there are no wrong connections or missing connections.
- Step 3: Connect Output Wires. Connect the B- wire of the BMS to the total negative terminal of the battery pack. Then, plug the sampling cable to the BMS. After activating the BMS, verify that the voltage (battery voltage) between B+ & B- and the voltage between P+ & P- are consistent.
Important: Incorrect wiring can damage the BMS and/or the battery pack. If you are unsure, seek professional assistance.

8. Safety Information
Always adhere to safety precautions when working with battery management systems and high-voltage battery packs.
- Ensure all connections are secure and correctly polarized before applying power.
- Do not short-circuit the battery terminals or BMS connections.
- Avoid exposing the BMS to extreme temperatures, moisture, or corrosive environments.
- Only use the BMS with compatible battery chemistries and cell counts as specified.
- In case of smoke, unusual odors, or excessive heat, immediately disconnect the power source and consult a professional.
- Keep out of reach of children.
9. Operating Guidelines
To ensure proper operation of your DALY Smart BMS, follow these guidelines:
- Initial Power-Up: After wiring, connect the main battery terminals. The BMS should power on automatically. If not, check all connections.
- Monitoring: Regularly check battery parameters via the smartphone app or connected display. Pay attention to cell voltages, temperatures, and overall pack voltage.
- Charging: Use a charger compatible with your Li-ion battery pack's voltage and current requirements. The BMS will manage overcharge protection.
- Discharging: Ensure your load does not exceed the continuous discharge current rating of the BMS. The BMS will provide overcurrent and overdischarge protection.
- Equalization: The BMS performs passive equalization to balance cell voltages. Allow sufficient time for balancing, especially after deep cycles.
10. Maintenance
Minimal maintenance is required for the DALY Smart BMS. However, periodic checks are recommended:
- Visual Inspection: Periodically inspect the BMS and all wiring for any signs of damage, corrosion, or loose connections.
- Software Updates: Keep the smartphone app updated to the latest version to benefit from new features and bug fixes.
- Cleaning: If necessary, gently clean the exterior of the BMS with a dry, soft cloth. Do not use liquids or abrasive cleaners.
- Temperature: Ensure the BMS operates within its specified temperature range to prevent overheating.
11. Troubleshooting
If you encounter issues with your DALY Smart BMS, consider the following common troubleshooting steps:
- BMS Not Powering On: Check all main power connections (B- and P-) and the balance lead connections. Ensure the battery pack voltage is within the BMS's operating range.
- App Connection Issues: Verify the WiFi module is correctly installed and powered. Ensure your smartphone's WiFi is enabled and connected to the correct network, or that Bluetooth is active if using a Bluetooth module. Restart the app and/or the BMS.
- Overcharge/Overdischarge Protection Triggered: This indicates that a cell or the entire pack has reached its voltage limit. Check individual cell voltages. Ensure your charger/load settings are appropriate for your battery type.
- Overcurrent Protection Triggered: The load current exceeded the BMS's limit. Reduce the load or ensure the BMS current rating matches your application.
- Temperature Protection Triggered: The battery or BMS temperature is outside the safe operating range. Allow the system to cool down and ensure adequate ventilation.
- Unbalanced Cells: If cell voltages are significantly different, ensure the balance leads are correctly connected. The passive balancing function will work to equalize cells over time, especially during charging.
For persistent issues, refer to the detailed troubleshooting section in the full product manual or contact DALY customer support.
