Factory battery wire gauge

[simon_lefisch]

Does anyone know what gauge the factory battery wire is? I’m going to replace my battery soon and looking at getting some brass terminal connectors similar to this. Just want to make sure the factory battery wire will fit. Thanks

It looks like 4 gauge, not 0 gauge for sure.

Thanks bruv. I'll look at the correct sized terminals then. Much appreciated

The wires I added are 4 gauge. Either stock battery wire is a very thin jacket 4 gauge, but prob 8 gauge.

Nice work, I just got some 0 gauge from sky high. Orange of course.

So what did you do about the plug on the negative terminal (see screenshot)? I haven’t even looked into what it is yet lol.

Neg terminal goes on the brass post in pic. Here's another with it on. Only pic I have, I can get a better one. I made the block but some sell similar ones. Knukoncepts has another mounting block too

Actually I was asking about the connector thats on the negative terminal. Check the pic I posted where the arrow is pointing to. There's the battery cable but there is also a 2-prong connector that attaches to the terminal as well.

@curt d see the circled part.

So I finally looked up that part and found that it is a sensor. I assume it sense voltage from the battery (?). Not sure if its needed or if the car will throw an error if not used. Mind you, that part was looked up using my 2020 Si as reference. Idk if other trims have the same part.

The plug is still on mine. I'll take another pic in a bit. I'm running 2k watts and 24ah headway lithium cells in parallel with agm with no issues.

Actually I do see it now in your other pic. The first one didn’t really show it, then had to look a little more on the second one. Thanks for the info, much appreciated
