What’s the knob shaft dimensions for cutout

diameter 6mm =0.235'', length 10mm = 0.41''

What kind of battery can you power this with?

Mine has been playing continuously for an hour and ten minutes (so far) using a 3.7 volt LiPo battery. Battery was almost fully charged (4.1 volts) and is powering this little amp and a bluetooth receiver in a vintage tabletop radio converted into a bluetooth speaker. I would imagine this amp could also be powered by a single 18650 li-on battery

Does it come with the knob shown in the picture

Yes. The knob is a power switch and volume control.

What is the difference between this model and the discontinued dk-amp30w model? thank you!

I believe it is an upgraded design from the last board.
