Most power tool LI batteries don't have discharge control. You can always use Dewalt DCB1820 20V to 18V adapter to address this.

I have 1/4" foam around the external sides, top, bottom and back. I did not add dampening in the middle partition to leave room for reconfiguring the boards.

What's irrelevant, the speakers' 15W rating or my 15W limit? (I assume it's the latter as you mention stacking batteries. But won't that push the drivers over their limit?)

A bit expensive maybe, and one might want an 2nd charger (or at least the socket part) so you can really quickly swap batteries.
Yes, a scrap charger or tool sold "for parts" should do. I already have 3 batteries and that was part of the original idea. Easy swap would be critical as I imagine the battery would get drained quickly.

Uh, sorry, I misread—it's the volume control. Probably I would put it in the inset panel on the back next time. And change the power switch, which is what I had handy .That would make it more portable and less breakable.

You desoldered the one on the amp board? Or? How is it hooked up... I'd like to do something similar with mine, if possible?

The board I got is very basic, no onboard controls or jacks, just the input and output contacts. But I guess that unless your board is highly miniaturized, you should be able to desolder the potentiometer and move it somewhere else, or even replace it with one that fits your output/speaker setup better.
