oops didn't mean gamma rays.

look up typical magnet wire properties on Google. FWIW, I believe the higher voltage motors just use additional coats of varnish after winding.

Over on the DIYelectric site someone was commenting about some motor (honda?) has an inverter that doubled battery voltage to 500, so I would bet that 750 isn't unreasonable. You can also get motors rated for 408 vac which is almost 600 peak to peak. Some VFD's will run on DC, but make poor car controllers.

I still cant figure out a separation scheme for series batteries. based on my experiences, it is hard to not get full voltage leakage to somewhere. and high voltage high current stuff is $$$$$.
