Here is a 144v ford with 9" hauling a big load:

And here is a Long Range Toyota!

Im definately going to use a liftbed, to keep the box free. Im also keeping my eyes on the salvage yard to see if I can find a Canyon/Colorado.

The Toyota I knew about. That thing is a monster.

[sharp21]

What I dont really get about it is that its only 120volts...
Where is it getting the long range from!?

The batteries are wired in parallel and in series. I count 31 batteries in the back. I'm guessing one is for the standard 12V system. That means he has 10 banks (in series) of 3 batteries each (in parallel).

[sharp21]

Ahhhh
So the 3 batteries in parallel are still 12v, then 10 banks of those in series is 120V! Very interesting...
Does that mean though that acceleration would be slower than a regular 144v 9" build due to the lower voltage? (not counting the extra battery weight)
S.

[Daox]

I would think so.

[sharp21]

Got it.
Now I am just throwing this out there...
If the owner of that toyota one day decided to hit the drag strip, providing he had a big enough controller, he should be able to rewire those batteries all in series for a total system voltage of 360v? Any negatives to this, besides the time involved rewiring?
S.

The only thing I can think of would be rewiring and if the motor can handle the extra power without overheating.

You would need a completly different controller that could hande the high voltage, but some drag racing guys use very basic controllers, because all they have to do is dump amps into the motor.

Also, you want REALLY heavy duty battery cables for drag racing.

Also, unfortunately... that truck is gone. Garage fire.
