How do I know when my e-bike's battery and range extender are fully charged with the SCOTT TQ 4A Charger?

[Edmund]

To determine when your e-bike battery and range extender are fully charged using the SCOTT TQ 4A Charger, pay attention to the LED status indicators. The charger's LED provides clear charging status updates: When the light is off, the charger isn't connected to power. A red blinking light signifies standby mode, indicating no battery is connected. A green blinking light means charging is in progress. A solid green light shows the charging process is complete. A solid red light signals an error, which could be related to overvoltage, undervoltage, a short circuit, overcurrent, overtemperature, or incorrect polarity. For a more detailed view, check your e-bike's display to monitor the battery and range extender's charge levels individually. The range extender also has six LEDs on its side to display its charge status. Observing these indicators will help you easily track the charging progress of your e-bike's battery and optional range extender with the SCOTT TQ 4A Charger.
