And with a battery. I want the schematic for it. I don't have a 555 timer. So I'm wondering if a led chaser cuircuit can happen based off of just the 4017.

Here you are.  Notice since the 4017 only lights one LED lights at a time
ergo you only need one resistor.

Also on the two transistor oscillator you may leave out the LEDs if you wish.
