Re: (ET) Max power consumption on snowblowing....



How many amperes does it take to open the fuse link on the Power Disconnect ? That feat I have accomplished while underway. :)

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.
