Missing Details in JoyC Documentation

[sirtet]

I miss some things in the documentation (https://docs.m5stack.com/en/hat/hat-joyc):

• What is the switch doing?
  I can see that the led's are turned on and off, does it have other effects?
• What does the Battery do?
  Does it charge the StickC
• Is there a Schematic, like it can be found for StickC Plus etc. ?
  This would most probably answer the above question...
