BAT120 LEDs

This wiki page contains information about BAT120 LEDs and their actions.

Power IN LED

The IN PWR LED is the left-most located LED on the front panel:

Action	Description
LED turned ON green	PSU connected to IN PWR socket (batch 1-25) PSU connected to IN PWR socket, battery charging (* from batch 26)
LED turned ON red	PSU connected to IN PWR socket, charge failure /Vin too low (batch 1-25) Charging fail: temperature condition violation, PWR IN voltage too low (* from batch 26)

Power OUT LED

The OUT PWR LED is the second from the left LED located on the front panel:

Note: OUT PWR LED will illuminate green when connected load is greater than 0.5W. If the power consumed by an external device is less than 0.5W, it will still be powered, but OUT PWR LED will stay off or flickering.

Action	Description
LED turned ON green	OUT PWR socket connected to the device and external device is being powered
LED turned ON red	If the OUTPUT is shorted (requiring a reset) or the BAT120 has overheated (no reset needed), the OUT PWR LED will turn red, signifying an issue that needs attention (batch 1-25) BAT120 SHORTED/OVERHEATED; When SHORTED: make sure short is eliminated and reset the device using ON/OFF slider, when OVERHEATED: wait until temperature drops below 60°C (* from batch 26)

Power LEDs

The Power LEDs are located in the middle of the front panel:

Action	Description
LED turned ON	Shows BAT120 state of charge. Each LED equals to 25% of SOC (batch 1-25) This state does not exist (* from batch 26)

Combined LED states

Some of the states are shown with multiple LEDs:

Action	Description
Power LEDs blink every 5 seconds	BAT120 is in sleep mode (batch 1-25) Every LED is 25% of SOC (* from batch 26)
