1.
Low voltage: When the battery capacity is less than 5%, the red LED will flash and the motor will
vibrate 3 times as a warning. After the end, it will return to operating mode 0.
2.
When the battery voltage is greater than 3.8V, the blue LED will be on. When the battery voltage
is greater than 3.3V, the yellow LED will be on. When the battery voltage is greater than 3V, the
red LED will be on.
3.
During the charging process, the corresponding LEDs will be controlled with the breathing
illumination effect. This is a continuous process of alternating from fading to brightening.
