4. Instal·lació i cablejat
Proper installation is crucial for the safe and effective operation of your DALY Smart BMS. Follow these steps carefully:
- Step 1: Solder the sampling cables. The first black cable in the sampling cable set connects to the negative terminal of the battery (B-). The second cable (red) connects to the positive terminal of the first string of batteries. Continue this pattern for all subsequent cables until all strings are connected.
- Step 2: Check the cables. After connecting the cables, use a multimeter to measure the voltage between two adjacent cables starting from the header. Ensure there are no incorrect connections or missing connections.
- Step 3: Connect the 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 (bateria voltage) between B+ & B- and the voltage between P+ & P- are consistent.

5. Instruccions de funcionament
5.1 Mobile App and PC Software Monitoring
The DALY Smart BMS can be monitored and configured using a dedicated mobile application or PC software. The included 2-in-1 Bluetooth/Wi-Fi dongle facilitates this connectivity.
- Connexió Bluetooth: For local monitoring, connect the dongle to the BMS and pair it with your mobile device via Bluetooth. Open the DALY app to view real-time battery status and adjust parameters. The BMS supports a Bluetooth activation-free function, allowing direct wake-up via the app.
- Connexió Wi-Fi: For long-distance control and monitoring, connect the dongle to a Wi-Fi router. This enables remote access to battery data and settings through the mobile app or PC software from any location with internet access.

6. Manteniment i bones pràctiques
To ensure the longevity and optimal performance of your LiFePO4 battery pack and DALY Smart BMS, adhere to the following maintenance guidelines:
- Seguiment periòdic: Periodically check battery parameters via the mobile app or PC software to identify any anomalies early.
- Condicions ambientals: Operate the battery system within the specified temperature ranges for charging and discharging. Avoid extreme heat or cold.
- Integritat de la connexió: Regularly inspect all wiring and connections for tightness and corrosion. Loose connections can lead to resistance and heat buildup.
- Actualitzacions de firmware: Check for and apply any available firmware updates for the BMS to ensure you have the latest features and bug fixes.
- Equilibri cel·lular: The BMS actively balances cells. Ensure the battery pack is allowed sufficient time for balancing, especially after deep discharges or prolonged use.
7. Solució De Problemes
This section addresses common issues you might encounter with your DALY Smart BMS.
- BMS Not Responding/Waking Up: If the BMS does not broadcast a Bluetooth signal or appears unresponsive after prolonged inactivity, try connecting a load or charger to the battery pack to force a wake-up. The Bluetooth activation-free function should allow app-based wake-up.
- Problemes de connectivitat de l'aplicació: Ensure the Bluetooth/Wi-Fi dongle is securely connected to the BMS. For Wi-Fi, verify your router connection and internet access. If using Bluetooth, ensure your mobile device is within range.
- Vol incorrectetage Lectures: Double-check all sampling cable connections as per the installation instructions. Loose or incorrect connections can lead to inaccurate cell voltage lectures.
- Battery Shutting Down Unexpectedly: This could be due to protection triggers (overcharge, over-discharge, overcurrent, temperature). Check the app for fault codes or protection status. Ensure your load does not exceed the BMS's current limits. Regenerative current from certain loads (e.g., golf carts) is managed by the BMS, but extreme conditions can still trigger protection.
- Poor Cell Balancing: While the BMS provides balancing, significant cell voltage differences may require extended balancing time. Ensure the battery pack is fully charged and allowed to rest for the BMS to perform passive balancing effectively.
