APP Connectivity
The BMS supports remote monitoring and management through the DALY BMS APP, utilizing 4G connectivity. Users can track battery status, State of Charge (SOC), and other parameters via the application.
LED Indicator Status
The device features LED indicators to display operational status. Specific patterns and timings are used to convey different states:
- Low Battery (<10% SOC): Indicated by a pattern involving 30-second intervals.
- Very Low Battery (<10% SOC): Indicated by a pattern involving 30-second intervals.
- Normal Operation/Status: Indicated by various timing patterns such as 60s, 35s, 0.5s ON / 2s OFF, 10s, 3~5s, 120s, or 10s ON / 2s OFF. (Note: Precise meaning of each timing requires further documentation).
