For my 2001 LX470.
I'm about to buy a set of these:
But what AWG is required? I think the 20 ft ones would be more useful, and then I'm looking at a voltage drop calculator:
But I don't even know what voltage at the end of the span would be sufficient (so what amount of drop is tolerable).
And all this depends on how many amps the starter will pull. I saw someone selling a replacement starter motor that seemed to be rated at 1.4 kW.... does that sound right?
This is assuming that I'm starting MY truck from a donor vehicle, with its 4.7L v8, which is a "big" engine. I'm assuming I won't be trying to use my truck to start even bigger vehicles.
Of course, I also want to get the smallest cables that will work, for storage size, weight, etc.

Spartan Power Heavy Duty Jumper Cables 4, 2 & 1/0 AWG
Made in the USA, Spartan Power heavy duty battery jumper cables come with powerful clamps that provide power to both sides of the jaws.

Voltage Drop Calculator
This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.
