E peak on utility power is 1.414 times RMS or 165 volts. converting from a 170 volt battery bank the electronics could be a buck regulator and an H bridge. Never seen it done that way though. Sure would be simple electronics.
BTW these folks have good prices on Edison cells
no sulphation. lifetime is many times lead/acid
I think price was a major factor but these folks mitigate much of that. Over 20 years they would be cheaper than lead/acid

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.... .etc etc.
I really wish Outback or Mastervolt would put together a decent quality inverter/charger setup for higher voltages. but as it stands now 48 volts seems to be the highest voltage that mass market accessories are made for.
If you do run across a source for pure-sign inverters for high voltage please let me know.
