I’ve thought a lot about this actually and have a few options. Batteries are limited by how much current they can put out at once but fortunately woofer power ratings are not actually how much power they use, and because you have capacitors in your amplifier you don’t need to “feed” the system high-amperage peaks of electricity - the amp will draw a constant(ish) amount of power and feed the speakers the spikes they need. So if you use a 200w (total) amplifier you can prob get away with 50-75w of draw on the battery. Totally doable but not great for 18650s - need a bunch of them. The Soundboks uses a battery configuration like this which is the form factor of a scooter battery. Fairly light, can pump out plenty of watts. I have not used the linked battery, but something in that form factor will be a good place to look. You can safely assume that all battery manufacturers are liars about capacity; buy 1.5-2x what you think you’ll need.
In your testing, get a meter and check how much actual power your amp is drawing when playing at “full” volume, then you can figure out from there how many watt-hours your battery needs to be for a given playtime on the speaker.
