Battery Location Cable Choice

[rfs324]

What gauge cable are you guys using for your battery relocation? Do I need a zero gauge cable or will 4AWG do?

I used 0 gauge wire for both power and ground a 4 gauge ground from negative to the motor.

no need for anything bigger than 2, 4 should work fine

I've always used 0 gauge for battery cable. 2 or 4 may work fine, but why skimp?

Wanted to use AWG oxygen free copper and the price difference between 4 and 0 is mind-numbing.

my best one IMO was 00 (yes double zero)

I've always used 0ga w/ a 150amp breaker for batery power and ground, 4ga for engine grounds. Most CCA wire can support a 250amp load while O2 free copper is like x3 the price and supports close to 400amps.

Both are rated substantially more than what the factory or even quest alternator can produce and the starter will draw. I've never hard an issue with this setup.

0 gauge for power and more than one 4 gauge for ground. I like to make ALL my engine to chassis, battery to chassis, and chassis to gastank/whatever 4 gauge. Socal schassis has the generic kit and i get a few additional pieces of 4 gauge from the home depot

As for a breaker/killswitch its always best to have a breaker, 140 or 160 amp depending what you have for acessories and if you have the alternator upgrade done. I like 2 killswitches as well. one on the cowl for anyone outside the car, and one within reach of the driver.

I used 1/0 from wire and cable on eBay. Avoid CCA.


Please don’t skimp on this crap. You’d be pissed if your car went up in flames over a shit wire. But you do you.

Did you use CCA or O2 Free or something else with your 0ga?

Thanks everyone for the responses!
