Any DIY battery Gurus on the forum?

Thanks, that's getting closer. I've read but cannot confirm that they use Panasonic 18650 Battery 3200mAh 3.7V Li-ion 10A 3.6V Rechargeable cells (NCR18650BD).

240v DC would kill you if you touched it. It's not the sort of thing you should be messing about with unless you know about the safety precautions.

Hmmn, yes, tried that once in the old days when one used to hold the electrical cables for power tools into plug holes with matchsticks.

(Don't try that at home on your own, kids).

No mate, that's A.C.
D.C. is a very different animal. Whereas AC will likely fire you across the room, DC will hold and burn.

That's A/C. It'll give you a shock, but it's fairly harmless. 250v from a battery is DC. It's lethal.

Not after when it's passed through an electric power tool it ain't. That's when you end up gripping the tool not being able to release your grip. I actually did that once in my idiot youth. It was only because I fell over that I was able to pull the other wire out, break the circuit, and let go. No idea what actual voltage it was. But it's a lesson I won't forget.

But, I take the point. 4 x 18Ah in parallel (72Ah) gives the same kilowatt hours of just over 4 which, even accounting for losses, should be more than adequate for hours of sounds. May be even power the trike at the same time too. Or at least some LED lights.

I just happened to already have a 240V, 1000W PA amp and wondered if I could use it rather than going for a 12/24V car systm.
