2. Safety Information
Adherence to safety guidelines is crucial for the proper and safe operation of the DALY Smart BMS. Failure to follow these instructions may result in damage to the product, battery, or personal injury.
- Do not charge the battery pack at temperatures below -1°C.
- Always follow battery management guidelines to prevent over-charge, over-discharge, and voltage imbalance.
- Keep the BMS and battery pack away from extreme temperatures and humidity.
- Ensure all wiring connections are secure and correct before operation. Incorrect wiring can cause damage.
- Only use the specified balance wires and cables provided with the BMS.
- Consult a qualified professional if you are unsure about any installation or operation steps.
3. Setup and Installation
Careful installation is essential for the correct functioning of your DALY Smart BMS. Please follow these steps precisely.
3.1 Wiring Connection
- Preparation: Ensure all power sources are disconnected. Tools needed include a soldering machine (suggested 662°F/350°C), scissors, double-sided tape, tin wire, and a multimeter.
- Balance Wires: Disconnect balance wires from the BMS connection port. Connect the balance wires to your battery pack, ensuring correct polarity and sequence.
- BMS Connection: Connect the main negative (B-) and positive (P+) wires from the battery pack to the BMS.
- Balance Wire Reconnection: After confirming all balance wires are correctly welded and installed, connect them to the BMS connection port.
- NTC and Bluetooth Module: Plug in the NTC (temperature sensor) and Bluetooth module into their respective ports on the BMS.
- Activation: Press the button on the Bluetooth module to activate the smart BMS.

4.2 Parameter Settings
The app allows you to adjust various protection parameters to suit your battery type and application. Always ensure you understand the implications of changing these settings.
- Cell voltage high/low protection limits.
- Total voltage high/low protection limits.
- Charge/discharge over-current protection limits.
- High/low temperature protection limits for charging and discharging.
- Balance start voltage and differential voltage.
The BMS also supports PC monitoring via the UART cable, providing a detailed interface for advanced users to view and adjust parameters.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your DALY Smart BMS and battery pack.
- Connection Checks: Periodically inspect all wiring connections for tightness and corrosion. Loose connections can lead to poor performance or safety hazards.
- Firmware Updates: Check the DALY website or app for any available firmware updates for your BMS model. Updates can improve performance and add new features.
- Environmental Conditions: Ensure the BMS is operated within its specified temperature and humidity ranges. Avoid exposure to direct sunlight, water, or excessive dust.
- Cleaning: Keep the BMS clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Battery Calibration: The BMS features automatic SOC calibration. For accurate readings, ensure the battery is fully charged periodically until the voltage reaches the high protection limit, allowing the BMS to recalibrate.
