Surely, with battery and motor tech where they are now, it is possible to make a cordless polisher that performs like the PCDA. Anyone seen one?

 

yah, ive seen an ad for it.... but i wouldn't get it. its like using a can of
propellant with an airbrush nozzle. you need consistency.

battery and motor is not consistent power in my books, especially running
higher current for long durations. another reason why i dont like using
cordless drills unless it's for a small project.
