Re: (ET) 48v electrac
Also, use a solid state controller - so you don't have the relay coil
issue
mentioned previously. (Though you probably want a dropping resistor on the
coil of the F/R relay, if you keep that).
I considered converting one of my E-Trac's to 48V because I have a 48VDC
3KVA
UPS that would happily run for a while, off a the pack - and could be
carried
on the rear tool box (modified) - then, it could run 110VAC versions of
yard
tools - or, power my gas furnace blower/controls during a power failure.
My plan was actually to continue with 6V Golf Cart batts, and add 2 into
rear
box - just because these are the most economical size of the battery.
So, Robert Winfield's question seemed like a good one, to me.
