- 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（バッテリー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.

9. 運用ガイドライン
To ensure proper operation of your DALY Smart BMS, follow these guidelines:
- 初期パワーアップ: After wiring, connect the main battery terminals. The BMS should power on automatically. If not, check all connections.
- 監視： Regularly check battery parameters via the smartphone app or connected display. Pay attention to cell voltages, temperatures, and overall pack voltage.
- 充電： Use a charger compatible with your Li-ion battery pack's voltage and current requirements. The BMS will manage overcharge protection.
- 放電中: Ensure your load does not exceed the continuous discharge current rating of the BMS. The BMS will provide overcurrent and overdischarge protection.
- イコライゼーション: The BMS performs passive equalization to balance cell voltages. Allow sufficient time for balancing, especially after deep cycles.
10. メンテナンス
Minimal maintenance is required for the DALY Smart BMS. However, periodic checks are recommended:
- 目視検査: Periodically inspect the BMS and all wiring for any signs of damage, corrosion, or loose connections.

11。 トラブルシューティング
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.
- アプリ接続の問題: 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.
- 過電流保護が作動しました: 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.
- 不均衡なセル: セルボリュームtages 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.
