#### LED and Power Behavior
| USB-C PD Charger NOT plugged in | System is OFF |
| ----------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- |
| Battery charging, USB-C PD Charger plugged in, Battery capacity < 5% | Fast blink RED LED |
| Battery charging, USB-C PD Charger plugged in, 5% ≤ Battery capacity < 60% | Medium blink YELLOW LED |
| Battery charging, USB-C PD Charger plugged in, 60% ≤ Battery capacity < 100% | Slow blink GREEN LED |
| Battery fully charged, USB-C PD Charger plugged in, Battery capacity 100% | GREEN LED is SOLID ON |
| Press PWR Button - ON mode | Solid YELLOW LED is ON and user shall hold the PWR button. Then solid GREEN LED is ON and user can release PWR button anytime then |
| Press PWR Button - OFF mode | Solid RED LED is ON and user shall hold the PWR button. Then RED LED will go off and user can release PWR button anytime then |
| Battery's temperature exceeds battery warm threshold or battery cool threshold | RED and GREEN LED blinks alternatively |
| a. Battery's temperature exceeds battery hot threshold or battery cold threshold
b. Battery is missing
| RED LED blinks twice consecutively then
GREEN LED blinks twice consecutively and repeat
|
#### Special Safety Features
