6. Installation und Verkabelung
Proper wiring is critical for the safe and correct operation of the BMS. Refer to the wiring diagram and follow these steps carefully.
Benötigtes Werkzeug:
- Soldering machine (recommended 662 °F/350°C)
- Schere
- Doppelseitiges Klebeband
- Zinndraht
- Multimeter
Verdrahtungsschritte:
- Akku vorbereiten: Ensure your Li-ion 3S 12V battery pack is assembled and cells are balanced.
- Balancerleitungen anschließen: Carefully connect the balance wires to each cell in the correct sequence, starting from the negative terminal (B-) of the first cell.
- Hauptstromkabel anschließen: Connect the main negative (B-) and positive (P+) wires from the battery pack to the corresponding terminals on the BMS.
- Verbraucher/Ladegerät anschließen: Connect your load and charger to the common port (P-) of the BMS.
- Connect BMS Balance Port: WICHTIG: Before connecting the balance wires to the BMS connection port, ensure the white end of the balance wires is disconnected from the BMS. Only after all black and red main wires are welded to the battery pack, connect the balance wires to the BMS port.
- BMS aktivieren: Plug in the NTC temperature sensor and Bluetooth module. Press the button on the Bluetooth module to activate the Smart BMS.
- Überprüfen Sie die Verbindungen: Verwenden Sie ein Multimeter, um die Lautstärke zu messentage between adjacent balance cables. This voltage should be approximately the nominal voltage of a single cell string.
Notiz: Keep the BMS red cooling surface side uncovered to ensure proper heat dissipation. Use DALY matching balance wires (regular length 450 mm / 17.72 inch).

7. Operating Instructions (Bluetooth App & PC Software)
The DALY Smart BMS can be monitored and configured using a mobile application or PC software via Bluetooth or UART connection.
7.1 Mobile App Setup and Usage:
- Lade App herunter: Suchen nach Suchen Sie im Huawei App Store oder Apple App Store nach „Smart BMS“ und laden Sie die Anwendung herunter.
- Verbindung zum Gebäudeleitsystem herstellen: Open the Smart BMS APP and connect to the corresponding Bluetooth device name (e.g., DL-XXXXXXXX).
- Anfangskonfiguration: For the first power-on, the battery capacity must be set to the actual capacity of your battery pack. The initial password for parameter settings is 123456. Failure to set the correct capacity will result in inaccurate SOC readings.
- Monitorparameter: The app displays real-time battery parameters such as total voltage, Strom, einzelne Zellvolumentages, temperature, and SOC.
- Einstellungen anpassen: Navigate to the "Parameter Settings" section to adjust protection thresholds for over-charge, over-discharge, over-current, and temperature.
- Automatische Kalibrierung: The BMS automatically calibrates when the battery is charged until the voltage reaches a high level 2 alarm.
