Battery relocation
 

Hello rotary freinds ;o)

Just thought I would share my recent battery relocation with you guys. I know the best options is to locate the battery in the trunk or the passenger bin, but I have the backseats and I would like to have the battery nicely hitten, so how did I do that ? first, I heard about a new lithium (gel) battery callede Ballistic EVO 2, VERY small and VERY light, they have it in a 16 cell type which I hoped would be enough power for my applications, so I ordered it, and can only say I am very pleased with the result. So, I messured that with a little work (and some clever thinking) this little baby could actually be in the storage bin, where the toolbox is (left side) the toolbox is now where the sparewheel is ;o) the routing for the cabels went through a hole in the driverside behind the wheelarch innersheild, came out down by the floor where the drivers feet are, routed alongside/under the panels, through the panel where the left rear speaker is and in to the storage bin where the toolbox is ! everything nice and clean, you have to take all the panels off in the trunk to fit the battery right in the toolbox bin, clamp it proberly down, and even a big fuse fit there too ! the negativ cable fits perfectly in there too, skrewed down to an existing bolt ;o) I am very pleased with this clean install and of course the battery has not so much Amp's (28) but good cranking Amp's, so far I have not had any problems starting the car and (actually starts better than with old BIG battery) I think this must be one of the most clean battery relocation, of course this will ONLY work with that fantastic little battery, I will post some pic's for you guys.

Very stealthy.

I asume that this is the Amp Hour rating? That's impressive for such a small battery. The Miata AGM battery that I used only has 3 AH more and it looks to be much larger.

Would you provide a link to your source? I'd like to check the cost / dimensions / CCA, etc. out.

You might want to cover that positive battery terminal - it is pretty dangerous as is.

Hey moconnor, yes I know ;o) I already have secured both + terminals.

James, I bought my battery in Germany, it is to expensive to buy it in the US due to 30% tax/VAT and shipping, but I read about it here: Ballistic Performance Components I belive you can buy it in more stores in the US, maybe here ;o) : very cheap, compared to what I paid in Germany ;o)

I like the idea, but the way it's mounted is quite poor. If you could make it sit flat and bolt it down through the wheel well I'd say, "well done!"

The battery is a lightweight baby, only 1.3 kg ! and it is tied down very well, sitting on a rubber mat, so no problem at all, I have been at trackdays with no problems at all ;o)

nice setup !

If it only weighs 1.3kg, why go to all the trouble to relocate it?

Nice project, different and another option.

Looks nice.
Seeing as how I'm a complete noob with wiring and suchlike, could you inform me on what sort of equipment I would need to relocate a battery? I'm looking at getting a v-mount, and it looks like I'll have to re-locate.

Also, if you want a smaller package battery, try shoraipower lithium batteries.

the one i have is the 36ah version. LiFe, and its in the rear bin of my Rx7

Looks good, I need to move my battery this winter, so I can install a large SMIC.

You've gotta do it like this:

-Braille Battery Tray bracket for Braille battery B2015
-Deka Big Crank ETX20L
-Stinger lines, connectors, terminals & breaker switch
-Deka battery tender/tricker charger connectors
-Follow Moconnor's write-up

A very good write-up that I used for mine.

Battery Relocation

XLR8 just posted the Moconnor write up

I use those type of batteries in my bikes and rc cars. They are not as simple as drop in and forget you have to balance charge them every once in a while with a hobby grade charger. You also need a cutoff switch, if you run lifep04 cells down they will not come back.

To be honest I don't think that battery will last in a street car. If anyone wants to make their own they are made up of headway cells.

turboIIrotary you're talking about the lithium batteries?

Yeah the Ballistic battery.

I just re-read the op's first post and my post is a moot point since he has back seats.

The link is dead!

Here is a link to the pdf version online: FD Battery Relocation

I'm not the one hosting it, but it would be wise to archive it before this site ever goes down.

Because I wanted that extra space in the enginecompartment, and simply just because " you can do it !" ;-) I agree, with this small size/weight it could be placed many places in the enginecompartment though :-)

Until now, I can tell, I have had no problems running this battery on a daily basis, but I have a professional charger connected to it when in garage (CTEK XS 0.8) to keep the battery in perfect shape ;-)

hmmm where exactly would you hook up the battery disconnect switch if you wanted to incorporate it? Thanks in advance!!

Aaron, check your email.
