I seriously looked into a Hi-voltage system, they simply cost less per KW delivered. The problem I keep coming back to was that there where very few accessories above 48 volts. So any money saved on the traction motor was lost buying expensive poorer quality accessories. An example is there are zero pure sign inverters on the market above 48 volts and the few modified sign inverters that take 144 volts where very feature poor and from companies you have never heard of before. Same problem for DC-DC conversion, same for chargers....

lots easier to electrocute yourself with higher voltage
accidents do happen
