Status LEDs
The LED on the left comes on to indicate that charging is occurring if the module is being used to charge a battery. The LED on the right comes on to indicate that charging is complete as the current being drawn from the module is reduced toward zero. It switches the LEDs between the two states when the current reaches approximately 10% of the current limit setting.
