I've used whichever 20V battery I feel like that day. I have most of rhe Dewalt battery line at this point. Just depends how light you want it to be. As for blades, many 3rd party 3" blades available.

So no problems like only getting 5 mins of cut time with a small battery?

Outside of the tiles I usually dont run it for 5 minutes at a time. Usually small tasks. Not sure I can claim to have an answer for your question or think of a scenario I'd need it to last 5+ min.

Are the wheels proprietary?
No. I had to file down the hole in the multi purpose wheel that came with it as it seemed to have factory paint on the inside but otherwise all good.
