Question about the Yocan UNI Pro fully charged.

I have a UNI Pro. When I charge the battery, the battery light and display are on. How do I know when the battery is charged? Does the light change color or go off. I'm stuck. Thanks for your help.


Answer:
The battery icon on the digital screen grows when you charge it.
( The same as you charge your smartphone.)

When the battery icon is full means your battery is fully charged.
