here is my Mclaren - kzfaq.info/get/bejne/pshjZsVlxNLXqJc.htmlsi=0GRe_wK_ILBx1DHi

I want it back

Rich is such a good friend. He bought a McLaren just to test a battery. That's so nice.

Rich just casually dropping his own Mclaren hahaha. I had a feeling that was coming at some point. The battery rebuild is some great content

He really rewarded us for making it to the end huh

I’m so glad old rich is back, I’ve missed videos like this

With all the joking around, Leenda thirst traps and Stroopwafel, we forget that Rich is a seriously smart engineer and king of all things electric. This video was a polite reminder that the man is the real deal. Thanks for the “Surrey” side up easter egg at the end!

Hey Rich, I worked for Tag McLaren in Woking, England as my first job after graduating from 1990 to 1992. I discovered recently that some software we wrote all those years ago is still used by the maintenance staff to service the McLaren F1 supercar - the software/hardware was also used to program and diagnose the formula one race cars of that era - the Ayrton Senna era. Who knew that in this world of almost everything being disposable there is something that I worked on that is still being actively used. I can't think of anything else in my career that has had that level of longevity. Oh, and after Senna there are no great F1 drivers :-)

Wow that ending was the ultimate flex. Congrats Rich, hope Steven is healing well. 👊🏾🙌🏽

Honestly, I'd forgotten Rich was actually this useful... 🤣

the community coming together to help Freddy on this huge project is great to see. Love to see it.

How did Freddy convince a bank to finance that vehicle he has incredible negotiating skills 😂

For a longtime we forgot that Rich is an engineer, this one is a good reminder 🤔

What the hell? I'm poor and there isn't a house UNDER $500k anywhere near me. Insane.

I do believe the A123 pouch cell are suppose to be held under compression as they swell under charge or discharge...maybe both...so they need to be sandwiched together tightly and evenly to prevent deformation...hence the aluminum compression straps and thick ridged end plates..otherwise all cells will swell under use..not just when they go bad...

You brought me back to my child hood with that rebuild, my moms boyfriend and i used to fix old beta tape players and solder new chips in place to make them work again, thanks for doin the damn thing and showing off the original skills that brought u to this point in your life. Keep up the great content!

As much grief as you give Sam in your videos, he always comes through for you.

After watching tavrish I’m thinking about buying a flooded golf cart strip it and re do it… 😂

you really did save the best for last... I wasn't expecting that buddy, you've made it!

Rich was feeling left out. Freddy and Sam both had McLarens, so he just had to.

Left us on a cliffhanger. How do I know… well I tested it on my own McLaren. Gotta GO. 😂😂😂😂😂

I could tell you're experienced electronics repairman by the sniff test you gave it upon cracking it open.

This is OG rich rebuilds stuff. Welcome back! I'm proud to see this!

This is the type of content I'm looking for

Dang! Rich casually pulls a car cover off of a 720s 👀

Priceless... ending... he peels back the car cover to his own McLaren.. 😅

Rich out there making you think it was for Freddy, come on now. Uncle Rich is always looking out for number 1. Great video!!

Right to repair at its finest!

I miss Stevon, but this gives hope hes coming back soon

Uncle Rich is the teacher we would all love

I like this style of Video. I haven't watched any of the videos since you finished IceT and this feels like one of the old school rich rebuild vids from back in the fix a crashed tesla days. I'm into it. nice work.

Gotta love the flex at the end 😅

Yaaaaaaaay rich got a new car!! Hopefully stevon is back too!

You have literally advanced humanity, the ev industry, and the repair industry. Thank you!

Most people don’t know this but the reason you need some play in the battery constraints is they actually change size when charging and discharging. Anyone can easily verify this by putting them in a vise with a load cell when charging, or alternatively use a micrometer before and after. It’s large at about 0.5% max difference.

I use a similar engraver tool at work and that stupid "spin to adjust" thing is annoying. Should probably make it a foot pedal with adjustable air. Love the classic video style. And your ad-reads are the only ones worth not skipping. Godspeed to the whole RR family. (including the ones we don't see as often)

Just a comment on the events at 3:59 - a bench power supply with both voltage and current limits is a great thing here. Set the voltage limit, set the current limit fairly low, let it trickle charge the battery until it's high enough for the normal charger to be happy. That said, doesn't look like it would have made a difference here since there were some cells that were completely shot.

Rich is the best youtuber narrator hands down!👏

As a battery technology student, i'm really worried about Rich's health. 😅 Edit: 2. Gen looks much better. Nice work🙌

Cells within cells within cells...interlinked

I love your intro. 1:22 Both houses below $575k? You clearly don't live anywhere in Canada! (exaggerating, but only very slightly). 7:45 the pouches are like those boil in bag lasagnas we used to get in MREs back in the day. They're making me hungry!

Easy to forget rich is a Wizard when it comes to the battery/computer stuff with all the spicy memes going around. Then he just casually drops a baby blue Mclaren on us.

You are a gentleman and a scholar, sir. When you said I tried it on my own McLaren.. I shed a tear; you made it bro ✊ Black success! Keep it up brother 👍🏽

Rich is back with rebuilds!

Great video Rich... I recently saw you giving advice on another channel regarding the $1,000,000.00 EV van. You were been asked questions about the electric motor and charging plug. People know to call Uncle Rich regarding EV troubleshooting. Oh yeah, there sure are a lot of Stevon fan boys in these comments. They seem to be MAN CRUSHING... Anyways, long live Uncle Rich!!

where is Stevon? He was in that McLaren video...

I lost over $60K when everything started to tank. Not because I was in an exchange that went belly up. I was just stupid to hold and because that's what everyone said. I'm still responsible. It just taught me to be a better investor now that I understand more of what could go wrong. It took me over two years of being in the market, I'm really grateful I find one source to recover my money, at least $9k profits weekly. Thanks so much Mrs Annmarie Surber

Rich, I love your content! But having useful info like this from a knowledgable guy like you is great.

The 3 taps on the battery after it started the diesel vw are proof of satisfaction. Actually, this vid was quite insightful!

Nothing more permanent than a temporary solution in tech (it seems)

Between the #RichRebuilds, #AgingWheels, and #TheQuestionableGarage channels, I feel like I'm learning something new while stepping outside my comfort zone. Bonus is I don't have to risk my vehicle to do it😁

Wait….when did you get a McLaren??? Can’t wait to see how that car progresses!

Rich and Sam been watching for a year. When my 06 Prius showed me the triangle of death I went to Toyota who wanted 3600$ to replace the battery with a reconditioned one. Two modules 60$, programmable charger 200$, and three days of conditioning. Car works fine.

You are officially the battery dude. I would have never known or thought to take apart the pack like that. Really interesting

The ENDING though!!! 🤣👍🏼

I'd imagine the conductive salt water acted like a resistor across the terminals and drained the battery to 0V

7:03 is the most excellent SPAM can opening technique I have seen in ages. That takes years and years of SPAM eating to master that technique! Way to go Rich, Mom would be proud! 😀

Dropped the bombshell at the end “Mclaren” way to go Rich!!!! Will there be a face off with Freddy at the end of all this???? Looking forward to what ever happens!!!

Rich you and the team stay creating different ways to repair EV's components including the battery

Rich, Exhausted on Franklin St in Worcester recycles these and even pays for lithium ion the same as lead acid. I collect and sell electronic scrap for fun and bring all my stuff there.

ROFLMAO!!! Best line yet! "They were about $2 million, which is about $1.999 million out of my range!" I hear ya there! 😅😂🤣

I've not actually seen so much info in a video from you guys for some time... Kudos. 😂👌🤣

Your a legend for helping out our boy that'll buff tavarish with the battery work

That ending was cold 🥶 I see you RICH! 😂

Brother the pouches individually are cells more than two cells and up is a battery. Originally a pile. The BMS can monitor each cell for voltage and also charge them individually so that all the cells come up to the designated voltage. For most lithium cells fully discharged voltage 3 volts fully charged 4.2 volts. I’m amazed at the price of houses in the US in Australia an average house on a 1/4 to 1/5 of an achar block is well over 1 Million $AU the exchange rate is currently $1US = $1.55AU. Our kids will have a very hard time buying a house. Love your work not usually pedantic but cells. Wobbels the mad Aussie.

Nice to see Rich doing actual work and not bs with Steven

A couple of milliamps for a few hours can revive a dead battery. But watch out with Li-ion batteries, once they have been deep discharged, they have definite dendrite damage and that means the battery can still work for a while and then just go dead real quick when the dendrites start to touch each other after a few more charges.

Not sure uncle rich, but I think this might be a proof of concept….😂

I love technical content like this. I hope you will repair the big battery too.

This was the best rich rebuilds video I’ve seen in a long time

Nice twist at the end buddy! You know you guys are gonna have to race now!

Seeing you stack those battery cells made realize that you must be a great sandwich maker Rich. Great vid and once again you are the man, Tavarish is going to be happy. Btw GREAT work on the "New version" looks OEM, just great.

He made that look more difficult than it needed to be. All you have to do is put the dead battery on an old school non smart charger. I usually use the “jump start” feature between 20 seconds up to 1 minute. Then switch to the smart charger.

Love the educational content.

I just realized, the fact that it was under water might have helped the battery fire stay so contained. Also sad to hear Tavarish is not dropping the hybrid system, its what makes a P1 a P1 so it would be interesting to know how that would effect its value.

I never knew those batteries had capri suns in them 👍🏽

Rich called Freddy an “up and coming KZfaqr”… 😂😂

You rooster! 🐔 So now everyone has a sneaky McLaren...... (I live about 2 miles away from Bruce McLaren's family workshop here in Auckland, New Zealand - where it all began back in the sixties, and yeah, he was a Kiwi racing car developer and driver). The big question for me; are you gifting the re-built battery back to Freddy ? Because we all want him to feel the love and we all know his pockets aren't deep enough to buy all the parts needed to rebuild the rusty P1.....A working McLaren battery could be your ticket to drive the most famous P1 in the world...... Let's think on that for a moment ! Long time fan - love the content - keep up the great work Rich. 👍🏼😎

BUT! did that include the Mclaren logo on it?

Since those are LFP cells there is a LOT less chance of thermal runaway starting a fire. Much safer than say an NMC based lithium pack.

Of course it ended that way! ❤uncle Rich!

I love the video, would have loved to see the build of the second version of the battery. Also, ugh... I think of myself as a loyal viewer. I did not know you owned a McLaren...

As fun as the meme bs is, this is far better content to me.

I'm a sailboat owner, and we often have more than one HEAVY batteries for our boats. However, we are always trying to reduce weight. I wonder if through this POC test someone could create a deep cycle marine battery that offers similar amp hours, but weighs far less. I guess the future looks bright..

WHERE IS STEVON HE DID THE P1 WITH YOU. WE MISS HIM STOP HOLDING OUT

Tavarish needs a bargain battery I heard. You and Samcrac need to help him dig out of the F1 money pit! Rich, I honestly learned alot from this video. Nicely done.

Something strange: in Tavarish’s video, Steve was there…

i love how simple you make it explaining the electrical part of the battery

Finished that like a BOSS!!

A123 actually made the pouch cell battery for the chevy spark also. It actually was a great setup too.

Rich willing to risk it all to bring us that awesome content 👏

Does that mean you’re going to fix Freddy’s larger and more expensive P1 battery? 😂

Where is Stevon ?

Did you add the metal plates in between each cell ? (looks like you didnt) - they are needed even in normal operation to prevent excessive expansion and damage to the battery cell. Just like the pouch cells on a Nissan leaf - is needed to keep a battery alive for any decent length of time....the Leaf uses strong bolts and nuts to compress the whole thing together.....

Someone had to say the senna was ugly 😂

My 2019 Mercedes S63 has the same Li Ion battery from A123 systems. Mercedes only charges 1800 for the replacement for what it is worth. The only rational for this battery is weight savings. If you can work your way around the Mclaren software you might be able to code the Li Ion battery nannies to turn off and just use an AGM battery. That is what I am going to do when my battery eventually dies. Sounds like Mclaren is an even bigger rip off than Mercedes which I guess is not surprising. Would love to source a new A123 Li Ion unit but sounds like they only sell to OEM manufacturers.

Impressive, Rich!

The DIY bus bars are perfect. 👌👍

Lmfao …up and coming KZfaqr Tavarish 💀

When Rich said “up & coming KZfaqr’ named Tavarish” I literally starting laughing my ass off 😂🤣😝
