5.3 App-installasie
Download the "BalanceBMS" app from your device's app store (available on iOS and Android) to monitor and configure your BMS via Bluetooth.
6. Bedryfsinstruksies
Once installed, the DALY Smart Active Balance BMS operates automatically to protect your battery. For monitoring and advanced settings, use the mobile application or a PC connection.
6.1 Bluetooth Monitoring (Mobile App)
- Maak seker dat Bluetooth op jou slimfoon geaktiveer is.
- Open the "BalanceBMS" application.
- The app will scan for nearby DALY BMS devices. Select your BMS from the list to connect.
- Sodra jy gekoppel is, kan jy view real-time data such as individual cell voltages, total battery voltage, charge/discharge current, temperature, and battery state of charge (SOC).
- The app also allows for basic parameter adjustments and viewing of protection status.
