Relocate 12v negative battery cable

This site may earn commission on affiliate links.
My 12V battery is tucked away, prior to the "right behind the frunk" 12V battery move. I have a single motor car, Aug 2013 build.

How to get and remove the battery is well documented.

My idea is to relocate the negative cable so that it is much easier to unhook the 12V electrical system.
I would probably keep the battery where it is, but put the other end of the negative cable near the fireman's loop, or close by, under the passenger side frunk trim.

Where is the other end of the negative battery cable?
Where does the other end of the positive cable mount to?
What is the bolt thread on the stock battery?
I am also considering building a tray, and moving the battery to the "new" location, behind the frunk.

Thanks
 
ground cable is easy since you can attach it anywhere to the chassis. but, you want the shortest length if possible, just use the right gauge. welding wire is the easiest to work with, and most flexible.
 
Hi No CO2,

I was looking at my battery and wondering if a hinged door on the back
of the frunk tub would be the way to go...

When you have a problem - Pop off the large plastic shield over the top
of the battery and fuse box and turn a few quarter turn latches and
open the door and there is your battery!!!

No problem with Tesla as the battery is in its original position and mounts,
it's just easier to access now...
