Is it possible to connect 4.2v battery pin to the Arduino 5v pin?

I tried it and it did not matter.

And  I used a level converter to level up voltage to 5V but it did not work.

I think it's not problem that to connect 4.2v to 5v.


I'm making pcb module and experimenting to supply wireless power to my arduino.

Help me, friends!!
