12/24

Doh!!! I cannot believe I said gas dryer. I meant electric.

That is correct. If a trolling motor draws 30 amps at 12v for a certain
thrust, a 24v system will only draw 15 amps for the same amount of thrust.
This is hypothetical. In practice, it will be slightly different. That's
the advantage of a gas dryer using 240 volts rather than 120 volts in that
the amount of current will be half.

A 24 volt system only uses half the current to do the same job as a 12
volt
system, a 36 volt system uses 1/3 the current.

So a 24 volt system only needs 12 volts to do the same job as a 12 volt
sytem? Hmmm....

I think you missed the point of my post. The post I mentioned mentioned that
a 24 volt system was twice as much as a 12 volt system. I thought that a
little obvious. But it's no longer funny when this is pointed out.

If I had a good 12 volt motor that was strong enough and in good shape, but I
wanted more battery life, I would keep the motor, add a second battery in
parallel to the first and double the time it would run.

At least that's what I'm doing... for a little while longer.

Has anyone ever tried running a higer voltage on a 12 volt motor. Since I am using 2x 6volt golf cart batteries, I was thinking that maybe I could get away with 3 batteries (18 volts) on the same 12 volt motor, and get a little more thrust out of it. What do you all think?

I think that you'll go like crazy....for a little while.

If you want to run higher voltage, buy a higher voltage motor. You can't
get Ferrarri performance from a YUGO and running 18 volts into a 12 volt
motor is a nice recipie for a toasted motor and/or fire.

Todd,

Current and Voltage are not the same thing. Think of voltage as the
rate of flow in terms of speed. Current is the power behind the flow.

Say a Mack truck is moving at 5 mph and it hits your car...disaster

If a bicycle hits your car at 5 mph..then there is a scratch. Thats the
diff between current and voltage!

Hey... I didn't say it.

Or even visa-Versa. Voltage is the push. Current is the amount of
electricity.

Here the voltage (5mph) is the same, but the current (mass of the
truck/bike) are different.
