My bad e*clipse. Seems you are way ahead of the guys on the insight forum.
Yeah I heard something the new prius 3 or v uses 650 volts as its more efficient even if its generated from a voltage doubler using the same prius battery the other cars use. I just dont see that many golf cart controllers rated for that amount, but then again this seems more advance and why those who pushed on with current 100 volt ev technology passed it on as with that low of voltage performance would of been on par with a kids power wheels toy or the motorized scooters for disabled people at walmart.
