RE: (ET) 48v ET

["Chapin, Tim" <tchapin umich edu>]

I remember someone doing a 48 volt et a while ago and it held up just fine.
I was also thinking that we have an electric ox dealer (or soon to be one)
in the group now.  Maybe we could leverage that.  The original ox was 36
volts and the last time I looked they still made them.  Here is a direct
replacement for decks, deck motors and blades.  I would think it can't be 
to
hard to retrofit the new deck motors to the et deck, but what I have heard
is the et decks around are getting pretty tattered so going to the ox deck
might be a plus.
I would guess the alltrax controller could handle 48 volts input so the
converted machines could go to the ox 48 volt deck stuff, trash the 
chargers
that a lot of people complain about, replace it with the of the shelf 
modern
golf car charger..

I would think that the new controller and ox parts, we can keep the working
et working....

Is a 48v ET doable? It would make things much simpler.
I could yank out that dratted charger and squeeze 4
batteries in that area. E12
Obviously it wouldn't void the warrenty but would it
fry the components with 33% more voltage. (visions of
Tim "tooltime" breaking stuff)
I am setting up Photovoltaics to do my charging
(shortage of big wattage PV in the US, Germany, soon
Italy and Spain are greening their countries with
federal subsidies so our prices are up)
24 and 48 volts seem a lot easier to get components
for
