How to Relocate a Battery to the Trunk *THE RIGHT WAY TO DIY*

[@throtl]

This IS a Re-Upload. We wanted to address a BUNCH of the comments/critiques/concerns so we decided to RE-UPLOAD with the changes that were suggested. We've now completed a successful and comprehensive How-To on this subject! Please show this some support and if you have additional How-To requests, please drop them in the comment section below!

[@TheCanadianPilot13]

throtl I saw the original, what were the changes made ? Just adding the positive post rather than running straight into the breaker ?

[@stevel.2759]

It looks familiar!

[@ja_]

Always connect positive first. Examples: Negative first -> accidental wrench contact with chassis while connecting positive completes circuit, risks welding wrench and exploding battery. Positive first -> wrench contact during positive install does not complete circuit, no problems. wrench contact with chassis during negative install completes no circuit, again no problem.

[@MrAuron34858]

WhiteSpeed13 one of the biggest changes was moving the circuit breaker. The circuit breaker should be as close to the power source as possible so if there is an issue the breaker trips at the source you don’t have that live connection running any longer than needed. They also routed the power cable through the car this time like it should be instead of under the car.

[@joelb2660]

Much better! Tiny point, if you shorted the battery posts, the circuit breaker wouldn’t trip. Which is why you correctly say you need the boots to cover the posts. Only shorting parts after the breaker will trip it. 👍🏻

[@CraaaigV302]

Much respect to these guys i ordered some stop tech front brake pads and I received rear brake pads I contacted them and they not only gave me a full refund but told me to keep the brake pads it was so unexpected super cool of them to do that much respect to the throtl team!

[@thomaswillman4187]

I stopped the video at the beginning because I wanted to comment on how humble the creators are! It is true to me that I don't have the best ideas but have ok to good ideas but like better ones!

[@photodave219]

I’ve never seen a channel re-edit and reupload a video like this and be totally transparent about everything. Mad respect. Keep it Mickey spec.

[@FlesHBoX]

Good on you for correcting the mistakes and reuploading, however I would suggest researching when commenters say something you aren't sure about. You don't want to connect negative first because it makes it easier to short the battery to the frame by accident. Until the negative is connected shorting the positive to the frame will do nothing because there is no path to the negative terminal for the power. This is less important with modern batteries that don't release hydrogen around itself that could potentially be ignited by a spark, but generally speaking, it's a good habit regardless.

[@Streetracinginschoolzones]

Hi, a tip I learned was that; it is still important today to connect positive first, because negative first could short or wipe the ECM by accident in cars

[@gimmieyogrits]

I've always known to connect positive first then negative, and opposite when disconnecting.

[@stigman3]

stay safe guys very nice tutorial vid like for dummies, no way to get wrong

[@yamilmelendez2667]

Lol for real

[@Marcury84]

What?? You said to attach the negative first. That is completely wrong. Who said that in the comments??

[@kingGar27]

What's the point in using such high quality cable and then earthing to the thin sheet metal in the boot? Why not run a negative back to the engine bay and do it right?

[@alluvz2fish]

Can you tell us where you got the RED CAP for the terminal stud?

[@TorontoSupraMan]

Should be a dry cell acid based batteries vent dangerous gases so in a trunk or hatch is bad also grounding to chassis is bad it should be grounded to block as well

[@jorgeandmaryvaldes9217]

Grounding to the chasis in the back will work but will cause a higher current draw during starting becasue of the increased resistance seen across the whole chasis. Ground for the starter is returned through the engine block, hence the factory ground on the right side of the block close to the starter. Best installation it to provide a return path as close to the starter as possible i.e. the factory location. The higher draw could cause the battery to struggle as it weakens. Sounds like the increased draw isn't a real issue with others.

[@peakauto]

Always coming through with that knowledge!

[@anginka]

Ok this may some newbie question, and I think its not explained in the video. What I do with the negative cable that was originally mounted under the hood? :)

[@jackcampbell2973]

Cant wait for some more civic content!

[@xcandiottix]

Question, if the battery is something like 600 cold cranking amps, and the starter presumably draws a few hundred amps, why doesn't the circuit breaker pop if its only a 150a breaker?

[@lancelaprarie6128]

Awesomeness

[@PemaMendez990]

interesting, I guess routing the wire under the car and placing the breaker on the engine bay are big no no's. thank you for this, I'm going to relocate my battery to the trunk as well and didn't know 80% of the stuff you showed here xD I though I just need a longer wire, a tray and bolt stuff down.

[@mickeyandrade3435]

Not a big no-no. It really depends on how your car is being used. In this particular car the install was perfectly fine/safe but, for "How-to" purposes and us not knowing what car that eventual watchers will be modifying it was critical for us to make a more comprehensive video. Lesson learned. On to the next.

[@sanjuan240]

I ran my power wire the same way on my s14. always thought it was sketchy running it under the car.

[@guglegugle8075]

Super video, fajnie wyjaśnione, miło się to ogląda👍Mam pytanie, jest jakieś przeszkoda by kabel minusowy (ground) uziemić nie tylko do masy w bagażniku ale również dodać go przez całą długość samochodu jak plusowy i uziemić rownież w okolicach silnika?

[@matthewanderson7882]

The excitement I felt for you guys at @12:49 when you cut through that wire like butter....I was right there with you on the opposite side of this screen man that was so satisfying lol

[@dragonext2001]

Hello I need alittle help. I'm relocating the battery in my lacrosse super to the trunk due to space issues. I need to know if I'm doing this rt. I routed the gauge 2 power cable to the engine by going under the back seat into the carpet and zip tied to the original wiring harness then back up to the bottom of the dash through the original harness grommet and zip tied all the way up to the engine. The original power cable disappears as it wraps around my v8 engine so was going to connected the new cable to the original using a jump post and ground the engine to the location I removed the battery tray from. Then connect a 100amp circuit breaker in the trunk going from the cable to the breaker then to the battery. Please tell me if theres something I'm missing coz it feels like theres something else I need to install. Thanks

[@dragonext2001]

Ohyea the battery is found cable is going through a grommet in the wheel well grounded to the chassis under the car. Theres a plastic wheel well that sits over the tire, the cable is between that and the metal frame then down underneath.

[@VWPassat_3BG]

This is the proper way of "How to" :)

[@Rob-md6ml]

Why are circuit breakers becoming a thing? The whole point of the main fuse is to protect the main circuit, adding the circuit breaker is one more point of failure and is only protecting the main fuse 🤷 . Also even though you can ground to chassis and it'll more than likely be OK, it's ideal and good practice to ground the battery to the engine block as close to the starter as possible to ensure the correct ground path to the starter whilst cranking.

[@mschvsmedia5178]

So what do you do with the original ground wire that connects to the battery? Do you connect it to the same post as the positive lead on the stud you installed?

[@chu13chu131]

[@pradipsingh6279]

Is it working properly still now Can we also swap battery with no problem

[@bidouchonsan]

i think it's a safer solution to add a breaker just after the battery, if your cable was injured in the car you could not stop the power. a better way would be to add a rally external breaker with a warning label.

[@mickeyandrade3435]

The breaker is mounted just after the battery.

[@midnightcoil]

If the car is crashed they cut the battery cables. Generally first thing done on a non track situation with any fire dept that knows what they are doing.

[@danielmiller3967]

Did I hear that wrong or..don't you always take the negative off first when removing a battery and put the negative on last when installing a battery or have I been doing it wrong the whole time?

[@MrTwoZZT]

19:30 Thats wrong according to what Ive always been told, you connect the positive lead first and then the ground lead, as once the ground lead is connected anything metal on the car is an earth connection.

[@gerik3343]

what is the maximum length do you recommend from battery to the circuit breaker?

[@jordanwasley5388]

1 -2 ft and secured down

[@oldscar6169]

don't touch the negative or the positive and you wont have to worry about turning on the spark machine.

[@PreludeDude]

I think you crimped the ground wire lug upside down. The point of the crimper should go on the slit in the lug.

[@dewaynemitchell3931]

Got a question the breaker its a line and a load side which one do i connect to the postive terminal to my battery

[@thisguy7392]

Disconnecting battery is negative > positive. Reconnecting is positive > negative.

[@frickhouse3542]

Ground last always not first. That way you can work on positive terminal without shorting anything out.

When you bolted down the battery tray, did you have to go underneath the car to put the nut on the bottom side?

[@gavnott4563]

Nice work . I still wanna see the old battery tray in the bay deleted. May as well do the old air box mount delete too. Will show guys how easy a partial bay shave can be with just a drill bit and some basic paint skills

[@CL-yp1bs]

There are OEM's that run power under the car... but it needs to be very well protected, and must be tinned copper wire (tinned OFC) - unless you have a very specifc reason to do it. just run it inside of the vehicle like a car stereo install... and yes fuse or breaker always as close to the battery as possible.

[@Bassotronics]

I probably did not see but, does the alternator ground wire connect directly to the chassis ground? The alternator spikes won’t damage the components?

[@red_dragonracingsilvereclipes]

good shit either way you install them under car you just need to secure the cables great so road debri doesn't try ripping them loose ,installing the cables inside just keeps the cable safe from road debri just make sure you route the cable where nothing will rub it but other then that your solid just like Mickies install is still enjoyed the vid even this way it's a good way to see how you should do things.

[@liggen]

Just run a wire from the positive terminal on the first battery to the positive terminal of the second terminal. Use a fuse for each battery, as close to the positive wire as possible. Find a new grounding point for the second terminal. Consider using a circuit breaker between the two batteries.

[@kevintong872]

What battery did you guys end up using. I had an Odyssey 680 battery in my EG and like you mentioned it didn’t last long. I ended up putting the battery back in the engine bay. The other issue I had was the car would lose power and I think it was the circuit breakers fault. Have you guys experienced that before?

[@treywayne2965]

For the guys doing this on newer cars, how did you get around the fuses on the front positive terminal? Doesn’t have the convenient 3/&ths connectors like this

[@larrysheran]

How many AMPS breaker?

[@hotflashfoto]

Relying on a plastic tray to hold a battery in the event of a collision could result in the heavy battery tearing the J-hooks out of the soft plastic and send the battery flying forward. Inside a trunk, maybe that won't end up in personal injury, but in an SUV or station wagon, it's a projectile inside the passenger compartment that nobody wants to stop! The breaker next to the battery needs to be sized to allow the starter to draw more than the usual so the breaker doesn't pop and strand you. 140A or 150A might work for a small engine, but with bigger engines, the starter draws more amperage and the breaker needs to be suitably sized.

Is it a good idea to upsize the stock ground wire from engine to chassis when relocating the battery? Seems logical that wire should be larger like the power wire or maybe it doesn't matter because it's so much shorter?

I've always used soldered terminals, covered in heavy heat shrink, with silicone inside, especially if you don't garage the car. The crimp style terminals always begin to gain impedance over time.

[@jeffcivjeep7]

What kind of solder? Solder melts when it gets hot enough, as you know, so I've always avoided it on power supply ends. I've seen it melt and start fires from frying circuits and grounding out power supplies of LiPo batteries and residential power.

Yes ....I agree with the first and many of these comments. Why did you introduce this as reintroducing the video as offering a comprehensive display of re-routing the battery. But in honesty, you guys didn't show us ANYTHING. You might have shown us that buying a positive post is a smart idea in the hood (or two, trunk etc.). I think when we (the commenters) are expecting a comprehensive video. I know at least speaking personally ..... examples being : where did you drill in the firewall?...did you drill in the firewall? ......Where did you run the 1/0 awg wire?.......Did you run it under the carpet or under the car?.......why did it look like the wire ran under the rear firewall because you have it coming up through the chassis metal using the grommet back in the trunk, so did you have a hole and grommet in the front?.......
