How It Works
The battery level indicator continuously measures the battery pack voltage. Based on the measured voltage, it illuminates the corresponding number of LED segments to indicate the approximate remaining battery capacity. As the battery discharges, fewer LEDs remain illuminated, providing a simple visual indication of the charge level.
