Einführung
This manual provides detailed instructions for the installation, operation, and maintenance of your DALY Smart BMS (Battery Management System) for LiFePo4 4S 12V 200A battery packs. The BMS features a programmable Bluetooth module for monitoring and parameter adjustment via a mobile application. It is designed to protect lithium batteries from various conditions including over-charge, over-discharge, over-current, and temperature extremes, while also providing cell balancing.

Sicherheitsvorkehrungen
- Beim Umgang mit Batterien ist stets geeignete persönliche Schutzausrüstung (PSA) zu tragen.
- Ensure all connections are secure and correctly polarized to prevent damage to the BMS or battery.
- Schließen Sie die Batteriepole nicht kurz.
- Avoid exposing the BMS to water or extreme temperatures beyond its operating range.
- Konsultieren Sie einen qualifizierten Fachmann, wenn Sie sich bei Installations- oder Bedienungsschritten unsicher sind.
Aufstellen
Enthaltene Komponenten:
- Smart BMS unit
- Balance wires
- Bluetooth module (for Mobile APP IOS & Android)
- UART cable (for PC screen)
- English version wiring manual (refer to this for detailed diagrams)
Verkabelungsanleitungen:
Follow the wiring diagram carefully. Incorrect wiring can damage the BMS and battery. It is crucial to connect the balance wires correctly to each cell in the battery pack.
Image: Detailed wiring diagram showing connections from the battery cells to the BMS, and then to the motor/load and charger. This diagram is essential for correct installation.
- Bereiten Sie den Akku vor: Ensure all individual cells in your LiFePo4 4S 12V battery pack are at a similar voltage-Pegel vor dem Anschluss des BMS.
- Balancerleitungen anschließen: Connect the balance wires from the BMS to each cell of the battery pack in the correct sequence (B-, B1, B2, B3, B+). Double-check the voltage between adjacent cables using a multimeter to confirm the wiring is normal and matches the nominal voltage einer einzelnen Zeichenfolge.
- Hauptstromkabel anschließen: Connect the main negative (B-) and positive (P+) cables from the BMS to the battery pack and the load/charger respectively.
- Activate the BMS: Plug in the NTC (temperature sensor) and Bluetooth module. Press the activation button on the Bluetooth module to activate the smart BMS.
Wichtig: Disconnect balance wires and the BMS connection port before welding black and red balance wires on the battery pack. Keep the red cooling surface side uncovered and use DALY matching balance wires (regular length 450 mm / 17.72 inch).
Mobile App-Verbindung:
- Download the "Smart BMS" application from the Huawei App Store or Apple App Store.
- Open the Smart BMS APP on your mobile phone.
- Connect to the corresponding Bluetooth device number displayed in the app.
- Nach erfolgreicher Verbindung können Sie view battery parameters and adjust settings.

Monitoring Real-Time Data:
The Smart BMS app allows you to monitor various battery parameters in real-time via Bluetooth. This includes State of Charge (SOC), current, voltage, temperature, and individual cell voltages.

Parametereinstellungen:
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. You can adjust various protection parameters such as:
- Überladungsvoltage-Schutz
- Tiefentladungsvolumentage-Schutz
- Over-current protection (charge and discharge)
- Temperature protection (high and low for charge/discharge)
- Bandtage balancing settings
Always modify parameters under the guidance of the battery manufacturer or a qualified expert to prevent damage to the battery or BMS.
Schutzfunktionen:
The DALY Smart BMS is equipped with multiple protection features to ensure the safety and longevity of your LiFePo4 battery pack:
- Überladeschutz: Stops charging when cell voltage erreicht einen festgelegten Grenzwert.
- Überentladungsschutz: Stops discharging when cell voltage sinkt auf einen festgelegten Grenzwert.
- Überstromschutz: Der Lade- oder Entladevorgang wird gestoppt, wenn der Strom die programmierten Grenzwerte überschreitet.
- Kurzschlussschutz: Protects against short-circuit events.
- Überlautstärketage Schutz: Prevents overall battery voltage from exceeding safe levels.
- Gleichgewichtsfunktion: Gleicht aktiv das Zellvolumen aus.tages to maintain pack health.
- NTC-Temperaturschutz: Monitors battery temperature and stops current if limits are reached.

Wartung
- Regelmäßige Inspektion: Überprüfen Sie regelmäßig alle Drahtverbindungen auf festen Sitz und Anzeichen von Korrosion oder Beschädigung.
- Sauberkeit: Keep the BMS unit clean and free from dust and debris. Ensure cooling surfaces are not obstructed.
- Software-Updates: Überprüfen Sie den DALY website or app store for any available firmware or app updates to ensure optimal performance and security.
- Umgebungsbedingungen: Operate the BMS within its specified temperature and humidity ranges to prevent premature failure.
- Überwachung des Batteriezustands: Regularly monitor battery parameters via the app to detect any anomalies early.
