Looking for Battery Relocation DIY
I'm looking for a spacific relocation DIY. Instead of using a regular battery, they used a marine, or maybe even golfkart battery; relocating it to the spare tire well. Does anyone know the URL of this DIY?? THX ~Colby

the relocation process is the same regardless of the battery type used. Keep in mind you'll want to seal the battery from the interior and externally vent it. (even gel cells produce hydrogen when charging)

I got a sealed/ vented battery box..plastic for $6 at a boat supply house. and the box came with a strap to hold it all down.
Do not put your battery in the spare tire well. if you get rearended.. acid all over the inside and you. also the rear end, back in that area gets a lot of vibration and extra movement, from racing. I have seen several metal boxes placed in the back past the tires and seen them breaks loose, shorts out,, all kinds of problems.. maybe because he runs 6s in the 1/8 mile.
I mounted mine right over the passenger tires next to the shock tower.

Thank everyone for their words of advice, but I'm looking for a SPACIFIC writeup. I'll be concerned with my well-being as a result of my own stupidity

Theres a battery thats used on hondas, that I think would probably fill the spare tire well well. All I know is the series has "51" in the number. Theyre easy to spot at the local auto store, theyre about half the width of a normal battery. Plus, theres already a hole under the spare tire, so no drilling for a vent!
Call me **** retentive, but mounting the battery in the spare tire well seems counter-productive. True, you've freed up room under the hood and moved weight off the front, but the weight is still outside the wheelbase.
IMHO, the passenger side storage bin seems like the perfect place (which is where mine will be going soon). And if you really want to get picky, move the battery around while corner weighting the car!

I agree NOT TO PUT THE BATTERY IN THE SPARE TIRE WELL!!! If u get rear ended the mother ****** gonna explode, and THE GAS TANK IS JUST A COUPLE INCHES AWAY!!!! So do not mount the battery in the back IF U DUNT WANNA DIE!!!!!!!!
forgot: www.fc3s-pro.com has a good write up on battery relocation and a good diagram. The perfect place for the batt is the storage bin. I think thats what the Mazda Engineer actually put those in there for.
well ok, see all that stuff under the hood that just all over the place and makes u confused and angry? take it all out for better weight distribution. also take out ur roll cage, that thing must be like 150#!

C'mon people... we all have full bumpers right? hahahaha where's the trouble with mounting it down in there? 
Actually, moving the batter to the very rear of the car would aid with the f/r balance of the car, and not really do much to the l/r balance you're all touting from locating it in the bin location. If you really wanted to find the best place for the battery it could be done with simple math calculating center of mass. Getting the original center of mass would be kinda tricky though. (ok so the whole calculating center of mass was a joke)
Batteries located in proper battery relocation boxes (not ones made out of aluminum!) have very little potential for causing anyone harm in a rear end collision if they were to be located in the spare tire well. The battery would internally short causing an inablility to produce current rather than a violent explosion. Proximity to the gas tank is less of a consideration than the tanks proximity to extremely hot tail pipes. Not only does the tank have a sealed metal shell of its own, it also has the entire floor covering it and isolating it from the battery. I've seen many collisions with vehicles where the tanks were bent to all hell and never ruptured. It really all depends on how much fuel is in the tank if a rear end collision will result in a gas leak anyways. (if its full the fuel will not compress and will find somwhere to go. in which case the exhaust will ignite it anyways)

Liquid, My block is more naked than yours will be....
You're actually putting the solid fuel lines and some vac lines and solenoids on your engine. I'm running braided stainless right from the rails. No vac lines other than the bare minimums and no hard lines on the motor at all.
If you were really doing this mod for weight loss consider the weight of a proper gauge wire long enough to make it from the original hot terminal to where the battery ends up. Those wires are about a half a pound a foot if not more. You're adding another 6lbs of wire not to mention the extra mounting brackets and such.

I'm fully aware there's a difference and I know exactly what each does...
I wish there was a way to determine center of mass on the car. A simple aviation calculation would prove how miniscule the difference in the two locations are.

BTW; I'm keeping my oil injectors, and 5/6th port actuation because... well, I can. This is my DD, and I enjoy having some torque. so what? I have a few more peices of silicone on my engine.
Christ, you're ****.

yea yea, moving batt to back would help with handling, etc. also u are hoping that ur gas tank will not rupture? how old is it like 15 years? neway if u want some good weight distribution put some dual 10 inch subwoofers there in the spare tire well. (like me) then put the batt in one of the bins. amp in the other bin. u can hook up amp easier, an ground ur ECU while ur at it.

I still have oil injection and working 6 ports... Your point?
I'm curious if you've even gotten your car running yet? You stated once that your car has been dead since day one on this board. that was like a month ago.
