Battery Relocation Writeup
Through the bin to the chassis. Even if I hadn't, that thing isnt moving anywhere. I test fit it just to the bin but changed my mind and got longer bolts to extend it to the chassis as well.
I used that battery relocation document as well for mine. This is what i came up with. If your looking for the breaker box you wont visibly find it as its mounted to the bottom of the board there within reach so i can trip/reset it as needed.
The battery you may not recognize, i have a post on it here on the forum. Its a voltphreaks battery. Pretty much a giant cellphone battery. I picked one up while it was relatively inexpensive compared to the current prices. The newer versions of the batteries are real nice. as it will never leave you stranded. If you want more details on this, contact me, as i dont want to thread jack, just want to show how i designed the bin with that document and my choice of the battery.
Thanks for making that document, it was very helpful.

Each circuit can only carry a maximum of 15 amps, which is not sufficient for sound system components.
Here is a link to moconnor's original thread with lots of discussion on the topic for anyone who wants to read the history.

Hey guys, been reading up on this and wanted to know where do you mount the factory ground at the front where the battery was originally? pics are great too...
Also is there room for a full size battery in the rear passenger side bin location? I know i have to hack it up just wanted to know if anyone put a red top or a yellow top (not 51r series) with the bins in place?

And on that note.... I just merged both threads so we don't rehash previously discussed info.
See posts and pics above Max

I looked all over those threads and it does not have a pic of the actual left over negative terminal from the front of the car or a good solid description of where to route the mount the factory negative wire!!! And the normal size battery i see pics of how much room but none of the actual successful install of that red top...Thats why i asked!!!

I have no idea what you are looking for with that. Get a battery tray like the one that I linked to in my posts on Page 4 of this thread for the mounting of my Optima red top and bolt it down to the bin floorboard. Its not that complicated really.
Hate to be the one to bring back a dead thread from the grave but this needs to be done:
http://www.ls1fc.com/pdfs/FD_Battery_Relocation.pdf
This should fix the dead link, well replace it at least.
Hope it helps someone.

Thanks for the PDF, I'm pretty car savy but I have never relocated a battery before. I just got my FD and it's the first thing I want to do.
Thanks again for the write up, seems many people enjoyed it because it was the easiest write up to find.

Here is a PDF of the write-up. I'll try to update the initial post with it too.
While I do not regret doing this relocation (particularly since I learned a crap ton doing it and have not been afraid of dealing with electrical problems on cars since), I would not do it again. It involves a significant amount of interior panel removal, something I have developed a strong distaste for. While it worked well in this particular case, this removal and reinstallation often results in hard-to-find rattles and many broken clips.
I did the relocation so that I could install a large (M2) intercooler. Since I did the relocation, many v-mount systems that work with non-relocated batteries have become available for the FD.
That said, this relocation has been pretty solid and the battery used in the installation is still widely available (for $150 or so).

No worries. I did my own relo but used your original post as a guide. I was going through my bookmarks and noticed the direct link to your original page was gone. I installed a greddy Vmount kit and the original battery location was moved by the previous owner but from what I see now, at least with a single turbo setup, I’m not sure where a stock battery would go with the Greddy kit but again, I haven’t had stock setup in my car since I’ve owned it.

Just went through all this. Antigravity batteries are tiny as hell, weigh 4lbs, and fit in the spare tire well in a battery tray. I bought a steel battery tray and welded that into the well. Expensive batteries, but for the weight, CCAs and not having to cut stuff, I'm happy for sure.
Less mAhs than a normal lead acid, but no cutting interior panels, just pulling cables to the trunk.
