I am making some power banks out of some spare 18650 cells I have laying around I am using a 5V Boost Step Up Power Supply Module.

The only issue i face is that these chips will allow themselves to output a higher current than they can withstand without external cooling. I am looking to regulate the current to 500mah at 4v. Is using a simple resistor going to accomplish this?
Thanks for any help!
