How to Relocate Your Battery to Your Trunk

PREVIOUS VIDEO ▶︎ • How to Install Tieferl...
In this video, I relocate my battery from the engine bay, to the trunk of my car. There wasn’t really a kit that I liked, that would have large 0 gauge wire, and made it look nice, so I decided to get the parts myself. If you’re looking to buy what I used, scroll to the end of the description.

I was almost going to use 1/0 cca but never knew that cca wire used for car audio could cause fires,you always learn some valuable information..do your research people.

[@JadielOrtiz-bn9mq]

CCA that's used for car audio ? We use ofc only rookies use CCA

[@PoorManMods]

Alot of people relocate the battery for weight distribution, it actually makes a big difference. If you remove a 40lb battery from the front driver side of the car, and move that 40lb battery to the rear passenger side, you now changed the weight balance by 80lb. You probably dont believe, like every comment on my battery relocation video, so let me explain. If you have a 40lb in your, the front of the car (just for example) weights 500lb with the battery in it, and the rear weights 500 without the battery. 500+500=1000, the car weighs 1000 as of right now. Now you remove that 40lb battery from the front of the car, making it now weigh 460 lb, you now add the 40lb battery to the rear of the car of the car making it weigh 540lb. 460+540= 1000, the car still weighs 1000lb, but now there is an 80lb difference between the front and rear of the car.

[@johny8145]

Poor Man Mods but if there's 4 wheels and its front wheel drive isn't it just making the front 40lbs lighter and instead of pulling its dragging/pulling 40 extra lbs from the rear?

[@EpilepsyWarning]

John y yea but that's a horrible thing to do in a fwd car

[@calhobbes862]

After you took out the battery, you can use the extra space to store your Mini.

[@jaylj0710]

I c wht u did ther lol

[@Matthew-ej3pg]

...

[@jasonhall5904]

As far as your full copper wire goes you can go to any welding supply store and get weld lead wires. They are full copper and have been used for higher performance stereo systems before stereo kits were a thing

[@wwmilanl]

did you put a FUSE on the battery conector??? so in case you have short the fuse will protected the car cable from going to fire?

[@drumsterbaby]

Isn't that built into most fuse boxes?

[@wwmilanl]

@@drumsterbaby you should put a MAIN FUSE between the battery to avoid a SHORT (potential fire) in case of some electrical short.

[@drumsterbaby]

@@wwmilanl oh how exactly do you mean?

[@zl_390]

@@drumsterbaby you would want to mount a fuse on the positive terminal in the location that's close to the battery itself so that if the battery failed it will cut off the connection immediately instead of burning your car down until it reach the fuse box in the front of your car

[@drumsterbaby]

@@zl_390 thank you! This should be more commonly known

[@jasonhall5904]

Use a wire wheel to clear the paint around your ground then coat with dilithium grease. That would be the correct way

[@johnjriden]

Do NOT use self trappers for your ground wire.!!!!🤦🏻‍♂️🤦🏻‍♂️

[@PRANKcallRAWR]

why?

[@alextavares3158]

It will loosen up in no time

[@steveg8637]

Please NO ONE use self tappers for your main ground.....Just because some kid does it on youtube does not make it right...

[@Tryant69]

The ground should go straight from the battery to the engine right? and from the engine to the strut turret? I would never go straight to metal in the car with a rear mounted battery..

[@GadGetHackss]

you've got ants in your car😂

[@GadGetHackss]

7:00 🐜

[@Midnightrider773]

get rid of those, that be a little weight reduction right there. That there be another 'How To, video'

[@Chris-go9ti]

So this is a how to if you already have a wire in the car to the back?

[@Chris-go9ti]

i c you touched on the positive cord at the end.

[@chrisneumann1667]

Literally one of the cleanest engine bays I've ever seen

[@milanmastracci]

Thanks man :)

[@chrisneumann1667]

Anytime!

[@Shalashaska016]

Your timing is impeccable my friend. was just thinking of doing this to make room.for a CAI. kind of cramped in the Hyundai. great food for thought when I get to it.

[@milanmastracci]

Glad to hear this is helpful for ya :)

[@meister3pc]

Milan is literally the only reason I'm on KZbin anymore.

[@snowboard13gcuz]

WARNING!! I really hope you don't plan on using more of that plated CHEAP "zero gauge" wire... that is the stuff that causes car fires. Don't let the thickness fool you. Do research. Go full copper or go home.

[@milanmastracci]

How is it cheap zero gauge wire? There was nothing about it that is cheap.. Its full copper wiring

[@akamusuapaia9542]

milanmastracci , you said it's full copper wiring but full copper wiring is never that flexible, and they usually don't have blue plastic or rubber coating. It's called 1/0 wire not zero gauge , but having a zero gauge CCA wire and zero gauge OFCA wire makes a huge difference. I would recommend to go homedepo or somewhere and pick up real copper 1/0 wire to relocate the battery. Don't use car audio wiring unless it's 2/0 OFCA wire or true 1/0 OFCA wire.

[@akamusuapaia9542]

Looking at the video you are running CCA zero gauge wire. Copper clad aluminum wire. Not safe to use that wire. , and use a ANL fuse holder.

[@snowboard13gcuz]

yes Oahu boy! I had a brain fart and couldn't remember what that wire was called. "CCA" If you do go to a legit stereo shop they should have full copper wiring for stereos. Also Best Buy is now required to carry and install full copper wiring because of multiple car fires using the CCA wiring. They WILL NOT install anything unless full copper is used.

[@snowboard13gcuz]

And Milanmastracci, sorry it's probably not "cheap" but its cheap compared to what Full copper wiring cost.

[@jonmar83]

Great video. But if I were doing this I'd put an inline fuse close to the battery, in case the cable shorts out and the car might go up in flames.

[@wingszeto1115]

I second that, put a fuse in-line next to the battery! A big fire hazard if it shorts.

[@jasonhall5904]

He's right you always put a fuse closest to the power source

[@josiahkaufman393]

Low key hinting towards a turbo which is why the Golf is on a budget 😉

[@activeej8858]

The golf is his brothers..

[@mickkarahangil3531]

Like explanations to a person never seen a car before fantastic

[@StefanikM]

Another great video. I like to watch how you're doing your car better and better. And how you showing how to do thing simple and nicer. Good luck.

[@willparsons32]

I've got a Dodge avenger...the battery is located in the wheel well of the car (a brain - wise idea from dodge!!) And I'm thinking about moving it to the trunk as well!! Although you have to struggle with your STEREO system, I'm not... All I'd have to do is run a 0 AWG WIRE from the engine department of o the trunk where I'd replace the battery.

[@aydgamer]

keep up the good work milan

[@cocoabod]

شايفك يا سعودي انتا شكلك مثلي تحب الفك و التركيب 😉

[@NFSWDark]

Very nice video only pain afterwards on doing this is getting the memory back like the radio, seat memory and etc lol

[@milanmastracci]

Meh. The couple minutes it takes to do that, I think its worth it

[@Tony-ml5bs]

I've been looking for turboed 97 corollas on KZbin but I can't find any. Probably cause there is almost no space under the hood. So I was thinking of doing this mod and removing the windshield wiper tank to fit a turbo.

[@jackyphotos]

Great video and necessary to consider the poison gas leakage of the trunk battery? thank for help.

[@KenMcBreezy]

not sure if you realize, but you had enough slack in the wiring harness that you should have been able to relocate to where you wanted without getting new wire. If not quite enough, you could separate the main from the wiring harness, which you would want to do anyway especially if you put a fuse block on there. Just a thought.

[@EVGUY13245]

Hey man. Do you have a video about how to wire a second battery into the car?

[@triniwarrior16]

Yea I would love to see that video too!

[@milanmastracci]

Deal :)

[@EVGUY13245]

Sweet! I wanna hook up a second battery to my accord. So let me know when it's released. :)

[@triniwarrior16]

would love to see you relocate the fusebox too

[@Codeman785]

Kevin Selagea buy a Yellow cap optima and you don't need a second battery. problem solved

[@waqaspathan3337]

I love the consistency of this channel, keep up the amazing work

[@milanmastracci]

Thanks buddy! :)

[@waqaspathan3337]

I'm new to this whole car modifying thing and I've got this question. what parts of cars are universally compatible if any?

[@johnnymuro3789]

so you dont really need a long negative cable? since its going to be grounded right there.

[@Shim1son]

Do a video on how to wire a 4 channel amp and speakers please

[@AzeOfSpadez]

Somehow i didn't get a notification in the sub box for this video. I saw part 2 and im like WHAT?? Luckily found part 1. Also funny because im literally doing this to my car as soon as a battery box comes in from amazon

[@accordingtoabe2211]

I'm seeing some comments here about safety hazards and the wrong wiring and such, so how has this held up over the years? still running the same setup as far as the wiring and tools used?

[@Allmotorzl1]

Keep up the informative videos. Library of information if i ever need so. Thanks.

[@milanmastracci]

Glad you're liking them :)

[@Mriluigi]

It would good for 2013 Chrysler 200 to move the battery into the trunk. Hate to take the wheel off just to change the battery.

[@hachi-rokuperformancegroup3987]

Just curious why you said you were going to move it further back and pointed the camera to the driver corner of the trunk and not to the passenger side for better weight distribution as that's the main reason to relocate it in the first place

[@Gardus82]

Cool video. I'm working on an oversize airbox and to do so I need to move the battery in the boot.

[@MrCaptainobvious9999]

Couple of issues with this instructional... (1) You should put a fuse on the wire running from the alternator to the rear of the car. (2) Please, do no use self tap screws to make a ground connection. Drill and use a nut and bolt.

[@Tierone1337]

Can I weld a threaded bolt to the car?

[@javierf9193]

Quick question instead of connecting the wire to the old terminal is the anyway you can just run a new charge wire straight from the alternator to the trunk?

[@grinbeefive4169]

Do you have any update about this? Like does it affect the way you start the car and how's the 0 gauge wire holding up?

[@TheSconat]

So much room for a turbo!

[@TheBlade616]

You should do a video on how to install subwoofers

[@سالكينالياللهالدرب]

What are the benefits to you from this? How much diameter of the positive wire? Do you connect the near negative wire of the engine in the car body?

[@brandonlamson8101]

Did you not have to move the fuse box as well...? I’ve been hearing stuff about it you don’t then you will start blowing fuses and stuff. !!Plz Answer!!

[@Jettrap505]

I have near future plans to do this with My 2005 Ford focus ZX4

[@bold58]

Can I put two batteries in the trunk ( the battery from the front with another ) and will my alternator charge them ? I drive a 2002 chevy prism.

[@milanmastracci]

You sure can!

[@cameronstark7193]

What about the emission of H2? Could this be potentially dangerous?

[@moeriou8431]

Cameron Stark what is his trunk gonna blow up?

[@akamusuapaia9542]

Make sure that car audio 0 gauge wire is OFCA wire. Don't use CCA wire. CCA wire isn't as conductive and running that length of wire can almost drop your voltage by 1volt. And the amperage can drop by a lot and may affect your cranking Amps

[@akamusuapaia9542]

Trying to help... I'm an audio enthusiast. I know a lot about wiring.. And thoes people are right, the wire will heat up in the long run and cause a fire. That 1/0 wire is cheap CCA wire. They are not good conductors and you will loose a lot of cranking amps. Use either real copper 1/0 from homedepo or something or use real true 1/0 OFCA wire. Check out GP car audio as they only sell OFCA wiring.

[@orficaldari3524]

So positive cable to original cable in engine bay ,then negative to chassis in trunk?

[@ideamr2]

I was just going to mention to make a video on exactly this project weird! I have the same car and had thought of doing the same thing! lol Great videos Sir!

[@milanmastracci]

What did you do with the original ground from the battery, you did not cover that?

[@alexanderandazola6138]

bro good job nikka good job

[@vaioskaliakoudas6388]

Can I connect the positive wire directly to the fuse box while I'm doing this? (If it's posible to do)

[@sailor5578]

Did you remove the heat shield under your hood? It looks really clean and all but I've read on some articles that it will shorten the life of your paint

[@YeetxBoi]

Colton Sailor it can if your engine is running too hot

[@syfax3697]

hello, I really like your videos so keep it up ! I just wanna know if some day you can make a video about car choices..for example the best first cars..or the most reliable cars and stuff like that..once again you're doing a great job !

[@milanmastracci]

For sure buddy :)

[@gamebws8708]

Can you do one on how to underseal your car?

[@jackiechan_wtf4041]

Did you mean " rust proof the undercarriage"? If you know what your doing, you can buy rust proof in a spray can, all you need is to wash it down, primer, then rust proof coat. But I get it done by a shop, because I get a warranty.

[@GutermanJunior]

Hi Milan. Do you measured voltage drop in the extension cable (between the battery and the original plugs)? Or the resistance of the cable... It is significant? Thank you :)

[@KrazeeeOne]

I was wondering about this. That is a huge wire.

[@snowboard13gcuz]

its a huge wire but it is definitely not proper and will cause over heating.. that wire is obviously coated and not full copper therefore don't do that.

[@milanmastracci]

How do you know its not fully copper? Because it is full copper. I made sure of that before I bought it

[@akamusuapaia9542]

That's not full copper, full copper is never that flexible. And that's CCA wire. That's very bad wire to use

[@akamusuapaia9542]

An 8 gauge real copper wire from homedepo is about as equivalent to that fake zero gauge wire that you are currently using

[@kenpuro5495]

Benefits of adding 0 gauge wire versus smaller gauge wire?

[@valkyriesurvives5109]

If its still useful after 5 years, the 0 gauge allows for minimal power loss over the extra distance

Sacrificing trunk space for engine bay space!

[@milanmastracci]

YESSSSS!!!

[@triniwarrior16]

Wait so can you show how you connected the positive wire to the 0 gauge in the engine bay

[@freezerlunik]

he probably didn't want to show it yet b/c he was not ready and "wants to do something better" there with the harness. The car would be driveable if he just bolted in the blue wire into the original connector, but it would just dangle there some, I imagine. Really, the video is not of a complete project...

[@HiddenInWakra]

Can I simply change the car from petrol to water fuel AKA HHO fully? Does it need parts, massive change and work or is it simple? Just asking for future projects.

[@DoctorWhoNow01]

You're joking, right?

[@luckym0nk3y]

No problem, but make sure to check the foglights. they will need more maintenance. and if you're exhaust turns green, it means that you should change your passenger seat in the next 3 weeks. and never but I mean NEVER drive the vehicle and look three times to your right. this will set the engine to block full out and you can have a accident. other than that, good luck bro. I already did 34,7 of these conversions and I'm happy with the results!

[@zackwaugh2779]

+luckym0nk3y As a certified mechanic, I can confirm all this.

[@HiddenInWakra]

I liked all your comments as if someone asked me 1 yr ago I would've respond the same. Actually it is possible as the hydrogen gas in the water burn more efficient than gasoline and with 0 carbon emissions, can I ask you guys just to take a few minutes of your time and go search ( cars running on water/ HHO) as I wouldn't believe it until I saw some attempts. TBH most of them are inefficient and look ugly, but there are some who surprised me but the have no tutorial for it. That's why I'm looking for a way. For that sarcastic guy 😂 I love your joke showed my friends and they are laughing on the floor 😂😂😂 thanks 😉

[@mikehernandez9567]

Nice Work

[@RazoE]

please make sure you use a sealed battery if you relocate it in the trunk. Batteries emit nasty gases that you do NOT want to breathe.

[@faisal3398]

Isn't almost every battery sealed?

[@cashivan]

faisal3398 maybe he meant a dry cell battery?

[@YeetxBoi]

cashivan no lead acid batteries give off fumes as they charge which they will be doing as you drive, since you're charging it off the alternator, but these optima batteries are sealed so he should be good

[@hyusama]

Most common reason is better weight distribution

[@santiagom7576]

Ok... But where's the fuse? Just in case of a fire or any other possible electrical related fire.
