Relocated battery under headlight (Page 1/2)
GTFiero1 MAY 16, 03:28 PM
Figured I share my battery relocation. Wanting preserve as much room in front compartment as I could, i wondered if anyone put their battery in the empty area under headlight/in bumper. Did a search here and low and behold, I found and old thread where FieroGuru had done just that. I based basic tray off his design and went from there.

Tray is 16ga steel, hold down 1/8 x 1.5 plate. Cut out sheet metal under headlight and fitted tray to be spot welded in the rear, and welded along edge up front as lip was thin. Hold down bolts to frame and J hook to tray itself. Small tab on bottom for nose support. Drilled out the old horn mount hole and welded an M10 nut that will serve as the grounding lug for the battery. Positive will have a 200a breaker right off the terminal

Nice job. I did mine about a year ago using aluminum plate. Took pics but don't recall posting anything.

i did mine under the headlight and i love how Freya handles then, and that is in comparison to the battery in the spare tire!

Here is my thread:

Astronomy says we will find a coded signal from outer space. Then we'll KNOW that life exists there, for coded signals aren't by chance.

Biology says there are coded genetic signals in every cell, but we KNOW that no intelligence created life.

Thanks for the shoutout! I was going to say that looked awful familiar! From back in 2008:
http://www.fiero.nl/forum/A...090907-2-093154.html

In 2012 When I built my LS4/F40 car I went a different path. I switched to a small dyna-batt battery and made a try that fit under the sheet metal. Less weight, no trimming of chassis sheet metal required.

Then I worked on the battery mount. I fabbed up these brackets to hold the battery, but ended up unbending one of the bolted flanges.



The battery is now mounted under the passenger head light, but the only modification to the sheet metal in that area was to drill seven 1/4" holes and remove the protruding flange from the 1" diameter drain hole on the bottom side. In the first picture you can see that the battery easily clears the bottom of the 88 coupe fascia (notice the 2 bolt air ducting bracket on the other side of the battery).


The mounting bracket holds the battery firm in 3 directions and the batter hold down tab secures it in the 4th direction.

Interesting project. I've seen battery relocation into the front compartment under the spare but this is the first I've seen off center. A couple of questions for you: 1) What's the advantage in relocating the battery to the front of the car? Do you notice any handling or ride issues with the additional weight of the battery so close to the front wheel? 2) What gauge wire do you use for the increased length of the battery leads?

@Fiero Guru

Can you give a little info on the BAT (battery) you have.
Positives an Negatives,

I read on the site it has 15hrs of energy, what does this mean.
Do I have to disconnect it when not in use, my fiero is rarely use, but if i fo out for a a weekend.
Should I have it on a constant trickler when in the garage?

Thank you in advance : )

There is absolutely no way that installing a regular sized battery at the corner of a car is going to improve handling compared to having it mounted low and centrally.

Dyna-batt is a relabeled/re-badged Motorcycle battery w/ high price really made by www.odysseybattery.com and Not made to start or run a car.
While fieroguru and few others likes/loves them, many have problems for many reasons.
