       That would be good and a possible way to go. 
       An option on my ev would be a 3,000 watt
inverter to run jobsites, house during blackouts,
band, audio equipmemt for rallies, parties away from
AC. The only way to do this is a pack voltage
inverter.
      Could you use a small 300 watt inverter to drive
a mosfet output stage? 
     If so could someone draw up a circuit for it as a
starting point? 120 to 156vdc pack.
     If I can't find a pack inverter on the market at
a reasonable price I'll build it myself but have a
very full plate right now.
     PS, I need to talk to someone about Rabbit Front
end body work. How hard to take the 1/4 panels off for
a diesel Rabbit I may buy for biodiesel use. I'll need
it to deliver EV's. Off list please!!

     Less costly than new DC to DC.
              Thanks,
