If the LED indicator of your DrivePro Body does not light up when the charging cable is plugged in (normally there should be a solid orange light), your DrivePro Body might be fully charged already.
For the updated version of the firmware, we have made improvements to the lighting behaviors. If you charge the DrivePro Body when the battery is already full, the orange light will go on for 5 seconds before going off.
Note: We would suggest upgrading the firmware of your DrivePro Body to the latest version.
