Have you considered using a 48 volt battery bank ? With a large standard inverter which could give 120 v ac for accesories and 175 volt DC for the motor. All sine wave inverters internally convert to high voltage DC before converting that to AC.

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.....etc etc.
