5. Guida all'installazione
Careful wiring is critical for the correct and safe operation of the BMS. Follow these steps precisely:
5.1 Schema elettrico
Image: Wiring diagram for the DALY Smart BMS.
5.2 Step-by-Step Wiring
- Preparare gli strumenti: Ensure you have necessary tools such as a soldering machine (if needed, suggest using 662°F/350°C), scissors, double-sided tape, tin wire, and a multimeter.
- Collegare i cavi di bilanciamento: First, connect the balance wires to your battery pack. Ensure the balance wires are welded correctly.
- Connect BMS to Battery: Connect the main negative terminal (B-) of the battery pack to the B- terminal on the BMS. Connect the main positive terminal (B+) of the battery pack to the P+ terminal (if applicable, or ensure the charger/load positive connects directly to battery B+).
- Connect Balance Wire Harness: Plug the balance wire harness into the BMS connection port. Ensure the red balance wire is connected to the highest positive cell.
- Collegare il carico/caricabatterie: Connect the negative terminal of your motor/load and charger to the P- terminal on the BMS. The positive terminals of the motor/load and charger connect directly to the battery pack's positive terminal (B+).
- Install Cooling Fan: Keep the red cooling surface of the BMS uncovered to allow for proper fan operation.
- Verificare il cablaggio: Before proceeding, use a multimeter to measure the voltage between adjacent balance cables. This voltage should approximate the nominal voltage of a single cell string, confirming correct wiring.
- Attiva BMS: Plug in the NTC (temperature sensor) and Bluetooth module. Press the activation button on the BMS to power it on.
Nota importante: Disconnect balance wires and the BMS connection port before welding black and red balance wires on the battery pack.

6. Guida operativa
The DALY Smart BMS can be monitored and configured using a mobile application via Bluetooth or a PC software via UART.
6.1 Installazione e connessione dell'app mobile
- Scarica l'app: Cercare "Smart BMS" in the Huawei App Gallery or Apple App Store and download the application.
- Apri l'app e connettiti: Open the Smart BMS app on your mobile device. Ensure Bluetooth is enabled. The app will display available BMS devices. Select the corresponding device number to connect.
- View Parametri: Una volta connesso, puoi view real-time battery parameters such as total voltage, current, State of Charge (SOC), individual cell voltage temperatura.
- Imposta parametri: Navigate to the "Parameter Settings" section. For initial power-on, the battery capacity must be set to the actual capacity of your battery pack. The initial password for parameter modification is 123456. You can also adjust protection thresholds for over-charge, over-discharge, over-current, and temperature.
