DIY: Battery relocation to trunk
PS - my car is all stock as far as electrics go (Bose system).
I thought about a breaker in the back, I just used a fuse because that's what I had. I still may put a breaker in when the weather gets a bit warmer and I have less projects on the go.
You don't need to re-fuse the OEM feeds( they are already fused
)...just anything you add to it...
You need a fuse or a breaker as close to the battery as possible to prevent your battery turning your extension wire into a very efficient DC welder

So now a 150 amp breaker by the battery and then a 60 amp fuse for the EPS? If so that just leaves me with how do i connect 3 wires needing power with one power cable? Power distribution block?
So it would be battery-->breaker-->on/off switch (i want mine in the trunk FYI)-->...travel from trunk to hood...-->distribution block-->60 amp fuse and EPS wire connected to the distribution block along side the main and fuse box wires?
hey guys i am about to do a batter relocation as well. i got a kit and some sub wire laying around. my kit is a 0 gauge kit for db link. it came with a power block and a ground block and a fuse block with 250 amps fuse in it.
1)should i use this fuse for the main power line or should i lower it to a 100 amp?
2) i do have the opportunity to run a 2 gauge ground to the back as well. all the way to the back. should i do that instead of using the body for ground?
3) the ground block has 4 ground connections in the front and 2 on the side which are larger. looks like 2 gauge. i can actually connect one of these larger ground input to the chassis and still have the opportunity to run a second ground to the battery. what should it do.
4) how the mother flood pukin do i add pics?

Great DIY, thanks. I will be attempting this soon. To be legal for the track, I will be bolting the battery down. Do you guys have any tips on good places to drill and attach the box and battery? The battery must not be held in place only by the box. There must be a physical connection between the battey and car body. J bolts or screws are not ok and I'd rather not use pop rivets, and I can't weld. The bent metal bracket that goes over the top shown in an earlier post was promising, but I could not see how it was attached.
I have an ally battery box bolted in the trunk with 4 bolts,2" plates underneath so they dont pull through the sheet metal, I used the original retaining clamp and J bolts , would this not be legal for the track ?

Been a while since I've been on. Good job to everyone who has relocated their batteries, and to the people who improved on the methods. I went to couple SCCA events and mine was legal so I don't know if that helps any. As for the gas tank I didn't drop mine.

Heres what I have right now. There is a 60 Amp fuse on the EPS line and then 100 Amp fuses for the other two cables, the grounds are both grounded to the main ground.
The battery has a 100 Amp fuse right after the line goes out and then its grounded to the passenger strut tower area. All 1/0 Gauge wire.
Anything I seem to be missing? I believe I have it all correct.
Well I was gonna start the car today and when I did I blew the 100 amp main fuse right after the battery. The car started to turn over then it popped.
Can anybody give me some possible reasons or let me know if this happened to them?

Well, here's mine... I went straight for the 0awg wires, ran the neative straight through the firewall (didnt know it would be a pita process at the time)...
ran along the passenger side (im rhd btw)...
through the rear seats and out to a little neat corner on the right (to balance out the driver's weight on the front left).
