Hi JohnMat
Thank you for your comment and your important question. I suppose more people will have the same question.
I will for sure put this question in my document, when people ask to publish it.
I can tell you that the wires stay cold at cranking and starting is fun and immediately.
I am not sure but I think you forgot the length of the cable.
Please have a look at the following calculation, hope I am correct and it clarifies the issue
Calculation
Rho CU = 1,68E-08 Ohm.m at 293K ; Length : lm = 3,00E-02 meter ( 3 cm ) ; Asurf = 0,0000015 m2 ; IA in Amps
R = Rho * lm/ Asurf - - - without Temperature validation
IA = V/R
IA = 12Volt * Asurf / ( Rho * lm )
Max Current at : 3 cm ; IA = 35714 Ampere = 35kA
Max Current at : 1 meter ; 1071 Ampere = 1kA
