Ooh ooh ooh! You guys have bigger motors!
The 3.5 hp motor in mine has a rating (according to someone online somewhere) of 98 amps @ 36 volts. So lets see how that goes:
36*98=3528
3528/750=4.704
3.5/4.704=.744.....
74% efficient sounds reasonable using just ratings here

Now what should I be pulling with 48 volts?
48/36=x/98
36x=4704
X=4704/36
X=130....
Right where it looks like I am on that paper he wrote up and taped on!

Yes we do pull over on that hill that gets us down to 15mph...

Maybe some used lithium cells and an Alltrax 4865 or 7245 (I think those are the two models...) I'm not sure yet...lol

Also, sorry about typos being...everywhere...I'm typing on a 4.0" screen...
