Battery cable thickness

[harrymini]

Would 25mm 170A cable be acceptable for the run underneath the car? The outer diameter is 10mm

The car is bored a little over 1275

Or should i go larger?

Thanks

16 sqmm is fine, but I run 25 and it eats it

Ditto, I use 25mm welding cable. Much better than the factory stuff.

Not a recommendation, just an example.
