Indicator Display Range:

1. 1S Lithium Battery Indicator Module: 3.3V – 4.2V

Battery status display:

1. When the battery voltage is over N * 3.3V, it will illuminate 1 bar (N represents the number of battery cells, e.g. 1, 2, 3 or 4).
2. When the battery voltage is over N * 3.5V, it will illuminate 2 bars
3. When the battery voltage is over N * 3.7V, it will illuminate 3 bars.
4. When the battery voltage is over N * 3.9V, it will illuminate 4 bars.
5. When the battery voltage is less than N * 3.3V, none of the bars will illuminate, indicating that the battery is less than 3.3V and in need of recharging.
