(ET) 48 volt?

["john briese" <goodguyforsure hotmail com>]

So I'm thinking (yes I know the dangers!) I have a 48 volt charger, why not 
add two batteries and go to 48 volts. The alltrax is ok at 48, the two 
contacts I have left in shouldn't complain too much. The only worry would be 
the deck motors and I don't think they would be a problem. I was thinking 
because I was running short of run time last night mowing.
What do ya think?
