Just how much current can a set of T105's provide?
The internal resistance of a golf car battery is about 0.003 ohms.
By Ohm's
law, I = E / R => 6 / .003 = 2000. So a golf car battery should be
able to
produce 2000 amps into a short circuit.
Well, this should help but I doubt anyone could drag a battery down to
zero on an E20. I'd assume 30 volts as the cut-off because below that
the contactors start to drop out and things get odd. So if we do that
math then we have:
30/6=5 volts per T105, or a 1 volt drop. I=E/R=1/.003=333a. Well
333.33333 but whatever.
So it sounds like a set of good T105's aren't going to put out any
more than 333a. Which is about the limit of what my batteries were
going to except my voltage was in the 35-36 volt range. So I assume
you just can't push a snowblower to the lofty levels there.
