ive never heard of that. a little off topic but do you guys think i can run 4 gauge as the grounds on my batts. its the only way i can do it without buying more 1/0 wire. sounds like it should work.....

You'd have to add at least two or three 4 gauge grounds to make up for the 1/0 ga.

It would probably be easier to just buy more 1/0 and run a single wire instead of multiple runs of 4g. Knu has good prices. If you absolutely had to run 4g, you'd be better off making the positive the 2 or 3 runs of 4g and giving the 1/0 to the ground.
