If you plan on racing it at any track it will need to have a safety kill switch as well as a vented sealed box like moroso sells. You will fail any tech inspection if not.

Where should the kill switch be mounted?
I'm planning to have the car street-driven as well, and reading through NHRA rules outside kill switch does not seem logical for a city car.
Moroso box
How easy is it to mount this thing in the trunk? Seems like it's plastic, but I'm guessing it's a great deal more sturdy than that stuff Autozone sells? Will it bolt in?
Thanks!

Do yourself a favor and keep it under the hood!
1. I have seen way too many electrical problems causes by relocation!
2. You will have to deal with the kill switch, if you ever want to take it to the track.
3. You end up making your car HEAVIER!
If you must move it, get a lighter/smaller battery, which will give you more minting options UNDER THE HOOD!

I bought a small odyssey battery and mounted it where the air can goes in stock position. making a bracket was simple and used a universal tie down you can buy at the parts store. Didn't have to reroute any wires and used the stock cables. Works great

Check out 1865's build thread. Location and battery is in a spot that won't interfeer and minimal weight.

1. If done properly, I have done quite a few relocations with no problems, charging issues/etc.
2. Agree unfortunately (mostly /ubbthreads/images/graemlins/wink.gif )
3. The weight is probably a toss up, but you are getting a bit better distribution F/R.

Never mind the minting, accepted that there are more mounting options under the hood. However, in the interest of expanding my horizons and learning just a little bit more,
a)why the electrical problems?
b)kill switch, fine, but where?
c)really? How? Same weight is being moved to a different location. Box weight is negligible, so, why heavier?
Not arguing, mind you, just asking so I can form a better-informed decision.

You could do something like this: Odyssey PC925 Battery Mount .
I didn't have to alter any of the battery or ground leads and it allows for a DSM style intake pipe to be installed if desired.

Any time you deviate from the OEM solution, you expose yourself to problems! Now, car enthusiasts do modifications all the time, but usually there is some real reward for doing it. What is your reward for moving the battery? “Better weight distributing” for AutoX or Road racing? It is totally theoretical as actual change is minimal! And for drag racing, you actually want more weight in the front! Reliablity will be 100% depended on quality of parts, design and work. But even when done right, more components give you more opportunities for a failure.
As for weight, you will have few extra pounds of HEAVY wiring, battery box and a kill switch. But most people use full size (or bigger) battery in the trunk. So instead of saving a 15-20lbs, by using Odyssey, Miata or loan tractor battery, you end up being 10-15lbs HEAVIER!!! That is up to 35lbs of extra weight… and why, again? For the theoretical “better weight distribution” for road racing?
I can see doing this if you were really into audio stuff and needed extra battery capacity.

My setup. Didn't have to change any wiring other than put in a new ground cable from the battery.

Saturn Alternator. I've had better luck with a relocated battery and Saturn Alt, than a stock location battery and Mitsu alternator. Just an option.

I think you are exaggerating a bit. 35 lbs? Everything you need to relocate to the trunk <i>might</i> put you in the neighborhood of 10-12 lbs. The main reason people move the battery to the trunk is to make that space under the hood available for other mods that can't be relocated to the trunk. I doubt anyone here does it for weight savings or better load distribution. There are quite a few members here who have relocated their batteries to the trunk and have never had issues. The charging system isn't negatively affected unless you've done something improperly, so that's a moot point IMO. Trunk relocation isn't the end all be all, but it's the best option for relocating a full size battery in my opinion. Relocating a small battery in place of the charcoal cannister is a good option as well.

1051 and 503 both have trunk batteries and have never had an issue with charging or starting. Done right, there shouldn't be any issues. And the added weight is negligible. Back when I moved it to the trunk in 1051, there were few options for smaller batteries to be kept under the hood that didn't have some sort of issue due to quality. That's changed now, so I see no problem choosing either route.

Really? Then why are you agreeing with me? /ubbthreads/images/graemlins/wink.gif I said TOTOAL, as in, including weight saving from a lighter battery! So 10-15lbs + 10-20lbs from a lighter battery. I LOVE Miata battery, which is 16lbs lighter than original DSM battery.

i like the lighter miata battery, it opened up room in the engine bay. it works great as long as you drive or throw on a charger a few times a week or it goes flat.

I'm not agreeing with you. My point was you are exaggerating the amount of weight added when utilizing a trunk mounted battery, which is true, especially if you start to count weight that could potentially be saved. Regardless of the actual weight added, the typical trunk mounted battery relocation kit won't weigh enough to matter on a street car. The weight added is negligible and is a moot point, as were the other points you put forth IMO.
If you want weight savings on a street car, stay away from McDonalds and roll around with a quarter tank of gas.

I've had my battery in the trunk since 05' (grounded properly & a kill switch) and 140k miles later Zero issues.
