- Today we install a Shorai battery that has 540 CCA and only weighs 5 lbs!
*Warning* Shorai does not support the use of their batteries in automobiles and it voids the warranty. I don't mind being a guinea pig. So feel free to touch base with me after some time has passed to see if it held up.
This is the battery I bought: www.amazon.com...
This is the Tender I bought: www.amazon.com...

Don't let this distract you from the fact that Hector is gonna be running 3 Honda Civics with Spoon engines. And on top of that, he just went in to Harry's and ordered 3 T66 turbo's with NOS..... and a Motec system and exhaust.
lol
Lmaoooo
The path of the righteous man is beset on all sides by the inequities of the selfish and the tyranny of evil men. Blessed is he, who in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy my brothers. And you will know my name is the Lord when I lay my vengeance upon thee.

@@chrisstojanovski5191 One of my all time favs ;)
Really glad to see you respond to older comments regarding the battery's life. I had one for my 86 and was great, was a tad worried about discharge over temps but I was thinking on reusing my battery box. Your claims have me on the positive leaning side a bit more. Cant wait to continue my baby's diet XD
Sub earned.
I used to work for a motorcycle shop as parts manager and a service tech and shorai batteries are amazing. There huge in the motorcycle world
I've been slowly getting my 8 more track worthy over the winter. This seems like a great mod! But dang, this battery is 420 bucks in Canada!!! Maybe next year :) Thanks for showing the step-by-step!
I've run a lawn mower battery from walmart in my na miata for like a year now, its like 10-15 pounds and $20.
That's all I ran in my Spec Miata lol
Really loving the vids Quinn. I myself own an RX-8 and have done a few mods myself. Next one is the Sohn Adapter.
Keep it up!!
Awesome Jake! Thank you!
Been using these batteries for years with great results! Enjoy the added lightness ;) Trd uses this setup in the griffon gt86.
Great video! I really like that pattern on tie down. Hey Quinn, you could tap that thread first, and then cut it to length :P would be easier.
Love all the videos man! It's only a matter of time before that subscriber list grows like it should.
Pretty Genius idea I must say, thanks for the video and your dedication to this channel
Thanks Ravindran!
That’s super light!
Love weight saving modifications, i love the set up. Excellent work!!
Thank you Jesse!
I've been using the same battery in my NSX without problems. Only catches are that you need to replace it every 2 years and it won't hold a charge for more than a week or so, so only worth using on a daily driver unless you disconnect while not in use. Optima Yellow top batteries are a bit heavier but still very light and possibly a better option for non daily driver cars.
You should skelaton the hold down for easy access to the chargeing port
I ended up just connecting the charging cable and ziptie'ing it off for easy access because yeah the hold down makes it more difficult to access.
Haven't read the comments, that's not a tap you're using to thread that bar boss. That would be a die... But still, confirmed my thoughts about how to mount a lightweight battery! Thanks!
I don't own a rx8 but you're awesome to watch!
Damn! Putting in work ! Tempting proposition to help My car lose 25 lbs or whatever the number was. But I’d be concerned about the battery not charging enough and the constant hot weather exposure. Also, did your tie down press down hard enough to prevent for-aft movement ? Good stuff Quinn!
Yeah I might be putting these in all of the cars. So far it's been good. And yes, even though it's just aluminum stock, the battery is so light it doesn't need much force to hold it in place.

Michael Scott!
This might be a nice idea for my Miata. Thanks Quinn
This is me in 2020 u was wondering if you still use this so I can use it on my 8
Same, I'd love to see what the current status of this battery is and if / how well it survived the heat of the engine bay. Edit: Earlier this year he said it held up well just don't jump it or let it die.
Another great video! May follow you lead on RX-8 improvements, once I get mine. Currently shopping since my NA is going on the shelf.
Thanks Mark!
@@TheSlipAngle Watching The Corded Tire podcasts and wondering on release of the 2019 look ahead episode. What plans are in the works and when will the meet & great event at Limerock?
Hey!
Now that It's been a year since you put the battery... Is it still working good? ☺ Thanks...
It's still holding up! I am going to get one for my S2000 soon :)
Alright Thank you so much for you replay... 👍👍👍
Thank you very much
I use it on my s2k. Works like a champ. The only thing is that their charger sometimes errors out.
Good to know!
Quinn, it would be cool if you could have a local engraver put the GQM logo on the tie-down.
That would be cool, but I don't know if that is worth doing to my .50 cent tie down lol
Great video as always. Could you do a rotary video?
Great job mate 👍
How is the long term with that battery. Do you think it would work on the fd. I would love to save some wieght. I dont want to add more power to make it faster
Well I just installed it so I will let you know. If it can crank the RX-8 13b with its higher compression with authority, I am sure it can do a lower compression FD. After driving the car and starting it with a full charge on the battery, it cranks it noticeably harder than the acid filled unit it replaced.
Hmm. My car is driven once to twice every two weeks. I wonder if it will stay charged enough to start the car. Dude if it does i will have tonpurchase one for sure
@@TheSlipAngle its been 9 months hows the battery doing?
do seats next plsss i wanna see how some good seats look and theres no one that does good seat install vids
How many hours can you play music with the stock stereo until the battery 🔋 doesn't have enough ⚡electricity to start the car?
Hi there sir, was curious how the battery was holding up, any issues ? still starting strong? I know its only been a couple months however i am still curious. great videos by the way really enjoy them , keep them coming :)
Hey bud, so far so good. No issues even with letting the car sit for a couple weeks at a time before the Spring. And thank you!
batteries. always thought they were just too heavy, and all that weight sits way too high in some cars. Legit mod, personally i think you will be ok with this battery . +Like , as usual.
Thanks bud!
Quinn your the man, love your videos and I'm basically doing the same thing with my 07 6 speed rx8 and funny cause I used to own a mr2 spyder as well. I gotta ask man what part of the USA do you live in
Jake Avers i beleve he is in Connecticut in the northeast us
Thank you Jake. James is correct. I am in CT.
Hi Quinn. After this mod, did you ever check the battery's temperature? I'm asking because modding the tray removes the cooling duct functionality and temps in the RXs engine bay are quite high. Thanks for your opinion!
I have not, but the battery is much smaller and farther from the engine.
How's the battery 2 years later? Do you need to trickle charge every day?
Hi,did you have any problem so far?is it still on the car?how about the temperature in the engine bay?
when you will give a new video from the rx8
Hmmm, chopped the tray. Hope you never have to go back to full size AGM
A used tray is only like 20 bucks, so I am not concerned.
Any reason you didnt just lay it on its side and tie it down from there? Little bit lower CoG and little more out of the way. Its lithium ion it shouldnt care about orientation.
It wouldn't really make sense to lay on it's side as it would make attaching the terminals more of a PITA and I didn't want to undue the factory wire looms to accommodate that in case this didn't hold up as a viable long term use solution. At 4.8 lbs it's not really going to matter which way this is mounted from a CoG standpoint ;)
Do you want to adopt a son. 40 years of age and no interest in cars honest lol. On a serious note lovely garage, collection of cars and great vlogs. I'm in the UK and have a RX8 PZ in Brilliant Black.
Thanks Ian. BB is my favorite color on the RX-8!
Thinking about about doing this how is the battery holding up to the test of time
love it great video
Battery time for me. How has this unit held up 5 years later??
On number 2. You need to keep it on the tender if not using for more than 1 week.
Just curious, how would an aftermarket sound system fair with this little battery over time, in your opinion?
I honestly can't offer much input. That is not an area I have really explored.
Any problems with the aftermarket steering wheel been debating to buy one or no heard problems occur wit the wheel
So far so good. I've really been enjoying it. I have had nothing but great experiences with the Daikei hubs and I would recommend that for the least BS with the install.
Hey so on your startup, the car chirps when it first fires. What is that from? My 8 does the same thing and idk whether to look at the pulley or belts. Nice Video! Thanks.
I think it's just the belts. It's done that since I've owned it.
I hate to revive old posts but it might be from the A/C compressor. Try starting g with the A/C know set to 0 and see if it chirps
The outtake XD
Doesn’t the voltage from the alternator affect the charge rate of this battery or for this battery rather?
It might, but I haven't had any issues so far.
Hi, where I can Buy the carbon reinforcement bar mazdaspeed? Thanks.
Mazmart
how is the battery holding up, considering the extra heat from radiator cooking it :D
3 years later and still going
@@TheSlipAngle This is a great information. I think you should do quick follow ups on staff like that as when I originally watched the video when it came out, I was wondering how it will live with cars charging system and everything :)
Thanks for taking the time to respond :)
Hey Quinn, let me know if this is a stupid question but I cant seem to find many other's opinion especially using this battery in the application we are. As it's a Lithium Ion is it fine to charge the battery while the terminals are still connected?
I had an issue where the Shorai was giving me the four light flashes with crazy beeping for the voltage code but then I tried hooking her up while the terminals were on for the fuck of it and its charging fine now?
I'm a little confused as to what's going on and if this is safe for the battery or not.
I always charge it with the terminals connected and have never had an issue. I've had the charger do weird things once in a blue moon but unplugging it and starting again cleared it up.
@@TheSlipAngle Get this, I called customer support since it's still "under warranty" and the 1ST thing they asked was if I was using this in a car LMAO 🤣 I just bullshited them and said it was in my Honda CBR 600 and they sent me a brand new one! Thing is the guy deff suspicious that I was bullshitting 😅 I literally had to photoshop the sticker from the one in the Rx8 into the one I run in my bike for the Customer Support quality assurance rep because the 36L3 just wouldn't fit in my CBR's tray... but I guess they fell for it 🤷♂️... that or they took pity on me.
Either way that's good to know, I'll just be leaving the thing on store then when I dont plan on driving the 8 for a bit
So after a few months have passed, do you consider them a reliable battery for daily use ? What about long term life ? Do they last less/just as or more than the conventional battery ?
So far I have not had any issues with mine, even letting it sit for a
week or two. Any downtime more than 2 weeks I use the tender for it
as recommended. A good friend of mine swears by them and said he has
not gotten anything less than 8 years of life out of them on his cars.
Meanwhile I contacted Shorai, they don't ship where I live and no distributor.. >
is this still in the car, and does the factory alternator charge it while the car is running?
Yes and yes
Update on the battery?
any disadvantages with a lithium battery vs a conventional agm ; im looking into light weight batteries for my miata
You are not supposed to charge these batteries with a conventional charger and I believe they have a little harder time starting in the cold. I've only ran this daily with warmer temps, but so far it is still holding up and working pretty well.
good too hear!! I would like to go lithium but probably wont because of the price, ill probably go with a pc680 from odyssey or similar one from turbo start, I do live in a cold climate ( chicago ) so cold starting is important but i don"t really drive it when it less than 20 degrees or that much in winter anyway.
I'm in New England and I'll drive my 8 in the winter when the roads are clear and dry, so we'll see how it does this year :)
Can someone link me a video explaining what all the weight reduction does and maybe with real world testing
Just watch all of the videos (or at least look at the titles) to get an idea of what he's done. I can think of: battery, exhaust (Primarily the stock exhaust manifold to header swap) pulley's, Cold air intake (AEM), Steering wheel (Nardi), wheels, and probably more, but those are the ones that stand out. As always, to each, their own. Mod what you think works for you. I'm going to take it slow with mods until I need a rebuild.
So how is it going with this battery? Any updates? Has it gotten too hot under the hood? Are you tempted to move it to the trunk?
Good so far! No issues with heat and no desire to relocate and add 10 lbs of cable to put it in the trunk :)
Nice, good to know. Any track days run with it installed?
Not yet, but we'll be filming a segment of the Slip Angle for it.
Nice videos...I am an rx8 owner from Greece...What is your opinion about a lithium motorcycle battery Skyrich 30Ah (HJVT-2-FP) 720 CCA?THANKS...
This is the only motorcycle battery I have tried so I cannot give any input about the Skyrich. The 540 CCA the one I am running cranks the car harder than the acid unit it replaced though.
Giotoules Cris did you used this battery?
Thank you .
Is everything good till now?
Still running strong!
The Slip Angle
I’m thinking to replace the battery for my V8 Camaro SS 2018.
Do you think it will work?
And why you have to buy battery charger?
Do you need it in the first time charging?
Car alternator will not help in the charging?
Thankful
This battery is 540 CCA. I don't know what CCA you need for that engine. I would guess more. You can't charge lithium batteries with a conventional battery charger, hence why I bought the charger for it.
The Slip Angle
Thank you, But any way the car alternator will charge the lithium battery when you start the engine, or what?
Thank you
Yes, I'd have a pretty useless car if my alternator wouldn't charge the battery lol
I liked it
I so want to do this to my BMW.
After doing this, my buddy with the silver E46 M3 said he was using a 240cc motorcycle battery in his car, but let it die completely on a few occasions so he didn't get that great of life out of it. He also said cold winter starts were an issue as well.
OK thanks. Might have to wait a coupe more years before this tech is more mature.
Would you put R3 seats in the rx8?
I would if they could be had on a good deal. The going rate is too expensive for what you are getting IMO.
There is a Guy on TH-cam from England fitted a whole R3 interior to his 04 rx8 ,says the R3 seats aren't as comfortable as the seats it came with.
You can do only 1 modification to an NA mx5, what do you do?
Garage Quinn Motors interesting, why. I thought you'd be all over FI
N/A 13b swap :P
I'm more of an N/A guy my man ;)
how's the battery working for you right now?
Still going strong!
Do you have a long term update on this battery?
So far I have not had any issues with mine, even letting it sit for a
week or two. Any downtime more than 2 weeks I use the tender for it
as recommended. I'll probably end up getting another one of these soon for another one of my cars.
Garage Quinn Motors that’s great news
Over $300 for a battery that needs a special charger? Ill take my chances with an optima car battery.
The battery was 250.00 and it's been holding up really well. The 40 lb weight reduction in the engine bay was definitely nice too.
How has this held up?
Good! Just don't jump it or let it go dead very often.
Any updates on the baterry?
Still running strong!
Nice :). Love your work!
I'm thinking to have one on my daily all year round mx5 nd.

I am afraid about battery hardware-terminals...
How come?
thanks for the replay...i am afraid that they are going to melt...
Why would they melt?
original battery has 70 Ah and the aftermarket battery has 30 Ah...
I am still not following how that would melt anything. I haven't had any issues since installing months ago. My friend ran this same battery in his MR2 for 9 years straight without issue as well.
