You have: 3800 Pa
You want: psi
* 0.5511434
Ya, well, 380 L/min is FAD, and 0 L/min is 0.55 PSI, according to the above.
It'd lift air mattress fabric off the floor, but that's about it, I figure.

It's definitely HVLP, and you need less volume and more pressure to mist
the liquid, I figure.

Well if one of "working pressure 15 - 50 PSI" and "Max pressure 25 PSI"
are true, then it's about 50 times better than the other. Dunno how it'd
handle one of your 6 hour convoluted gcode runs, though.

10 kWh battery options. Ya don't want the cheap ones, I hear.)
