  • Leave any questions here and I'll answer with an FAQ edit to this pin! Also don't forget to check out this video's sponsor - Private Internet Access: www.privateinternetaccess.com/DIYP

    • How many KWH is it?

    • QUESTION SIR, do you know this channel named "Future Unity" ? because i saw this video as clips in one of that guy youtube content, the video title is "IT HAPPENED! Toyota's Solid State Battery Finally Hit The Market!" i tell you this because i hate thieves!

    • What inverter did you use that had a 50volt input.?

    • Im looking to make a single 18650 battery bank using a DC motor to charge w/ USB-C output, what would I need to control charging so it doesnt catch fire?

    • I have only one question, that probably 1 in 10 people already asked - why not to integrate an DC-AC, you already did an excellent battery pack, all you needed is leave a little bit more room for 1-2kW inverter Otherwise - well done

  • Im starting to think this guy single-handedly keeps the aluminium industry alive.

    • @Ken More you pronounce your spelling correctly, and we pronounce our spelling correctly. all is fine.

    • As I do the bourbon industry.

    • @kaushal suvarna In America, we pronounce aluminum properly too. It just doesn't contain the extra "i."

    • also wood

    • 😂😂😂😂😂

  • Almost everyone: wheres my charger? Matt: in todays video we'll build an arc reactor using simple electronic scraps and a doorknob.

    • @MoltenHydrogen 🤣🤣

    • Modern Day MacGyver! Loooooovvvvveeee iiittttt!!!!!

    • @roland hazuki lol

    • Exactly LOL

    • Sorry sir but I'm not Tony Stark

  • Very nice battery pack 9:50 you are not only electrically insulating the contacts but you are also thermally insulating the battery pack. This means that any heat that develops in the battery is not able to leave the pack as well as it should. High energy packs are often lined with special silicone like material that directly attach to the metal case or even a heat sink. Especially when delivering high power over longer times it is very important to do this. Also, make sure there are a few temperature sensors to the BMS such that the BMS can switch off the battery when the temperature rises too fast or gets too high. As a safety warning: never ever suggest that people use old or refurbished cells to create battery packs with multiple cells, especially when those cells are placed in parallel. Any two cells that are placed in parallel will charge/discharge each other when these do not match. Not only the battery voltage but also the cell's capacity and internal resistance are very important. If these are too far out of alignment, the better cell will start charging the other cell(s) with uncontrolled/unlimited current (or as much as the better cell or cells can deliver). The cells you use can deliver up to 45 A per cell (not 30 A as stated by fogstar) when short circuited. So if one of these cells fails, you have a possible fire hazard. To prevent this happening, the BMS monitors the batteries over their life time and the BMS will shut down (and refuse to charge or discharge) the pack. The BMS will/should also monitor the temperature of the battery and with a large pack like this, there should be multiple temperature sensors on different places in the pack and with a pack like this I prefer to use 2, or even better 3, sensors. Note that even most electronics engineers have no clue on the use and care for rechargeable lithium cells. I have been working on multiple types of rechargeable technologies and have designed and built BMS systems on and off for the last 20 years. I know enough about Li-Ion, LiPo and LiFePo to know that I am not an expert on this ... When making a large pack with parallel cells, I would stay away from the BMS you mentioned in choice 2 and 3 (the "Small Daly BMS"). I base this on the label on the product that shows the text "with balance". The "M" in BMS stands for "Management" and that involves not just balancing but also monitoring the state of charge, temperature and capacity delivered over all charging cycles. As soon as this suddenly changes, the BMS must warn the user, at least by disabling the battery pack. If a manufacturer feels the need to specifically note balancing on the label this suggests to me that this might most likely just be a protection circuit with balancing. These protection circuits do not contain any electronics to "manage" large battery packs. The TinyBMS is the only sensible choice for this pack; it monitors voltage and current of each cell stage, monitors SOC, keeps track of number of charge/discharge cycles, starting capacity, last cycle's capacity and I think it will even show you the "health state" or "age" of the battery which predicts when your battery will fail. The TinyBMS also uses the temperature sensors to prevent charging when the battery is too cold. Future firmware updates might even contain a special features that start pulse-charging or slow charging when cold and only switch to full current when the battery is up to temperature. About "refurbished" batteries: Refurbished cells are a myth, these are just old cells recovered from a pack where other cells have proven to be faulty. Never ever combine those old cells to create a parallel pack because you do not get any clue on the age or life expectancy of such cells. You can buy things like "refurbished" E-bike batteries. Those contain NEW cells that are placed in the old housing with the existing BMS. The BMS is reset in order to keep track of the new cells states like current capacity and pack age. Such refurbished packs are as good as new ones from the factory. Some brands will even recycle BMS systems themselves, they have a system where a dealer gets a discount on a new battery when returning the old one.

    • thanks for the comment, very interesting

    • Legit

    • At first I was thinking" I am totally reading this long comment" then after the first paragraph I thought maybe I'll try to scroll down and see hos long it's going to be. Then realised even typing this long comment is taking less time so i stoped reading

    • @Dillan Nokes Good.

    • I feel like I just read a book

  • I don't know what to call this! I've been researching DIY batteries and power systems for weeks now; and nothing can be as professional and sleek as your work! I just love watching your brilliant work! thank you

  • Please appreciate that, not only does Matt realise some of the most awe-inspiring products that designers envy, he develops everything to millimetre precision, records the entire process, generates animated content, scripts his videos like a boss and edits the entire ensemble like a work of art. Kudos, Mr Perks!

    • i could never script my voice im way too shy, i do however laugh just like Darth Vader, tho everyone would probably love it lol

    • and he went outdors ;)

    • He still does things like saying “You make be wondering what this is, that’s something I added X amount of steps ago”

    • If he was hired in nasa a few years ago,we would have been living in Mars now..

    • @Alex Stone He's a real-life Macgyver

  • New to the channel but the production quality here is stunning. You really deserve every view, like, and subscribe earned here. I know you have mine. From an apprentice electrician and hopefully one day, electrical engineer, outstanding work.

  • I've looked at several power banks on Amazon in the last few months. I bought a small one that I thought would do what I needed it to do (charge/run my laptop), but then discovered that it didn't have the wattage required. I kept it, but right now it's in my car and I've only used it once to charge my phone for a few minutes when it started giving me a low battery warning, and it's there if I ever need to jump start my car. A unit as powerful as yours would cost a few hundred dollars. If you could get yours into production and at a decent cost, it could be a contender.

    • @L7vanmatre you ditch the small cells and you use the 100-300A cells.

    • just the cells this guy used would be around a thousand euros from where I live

    • @Oliver Walters not with lithium batteries. bigger capacities = bigger power delivery circuit = cost more. not to mention that the battery doesnt get cheaper when you purchase it in bulk

    • @L7vanmatre economies of scale is how companies make things like this "cheaply"

    • The 84 lithium cells alone cost £311.64, or 431.44USD. (If you order them at a thousand or more at a time, you'll get them at £302.4 per set of 84.) I see this handmade project being perhaps $500-$700 depending on how much one wants to spend (the BMS he used in the video seems to be the 170€ one, but you seem to be able to get one at $50 or $30 but as he said you might be sacrificing safety/reliability and losing out on useful features). Even just going into the probably-unrealistic lower end of that guesstimate, $500 of cost per unit... The overhead would be expensive. Even just the Galaxy Note 7 could cause some pretty scary stuff at 3.85V 13.48Wh. If any unit was improperly made in production, it could be pretty big depending on what exactly fails, so I think they would need extra precautionary measures in production... Which costs in two ways: less product, more expensive machines (or more employee-salary per product if it's all done by salaried employees, of which all are handling fire machines if they make a careless-enough move). I think all these problems can be resolved in one way or another that I might not be able to think of, but it surely sounds rather expensive.

  • The reason I love these videos so much is that they’re delivered in such an approachable way to keep beginners engaged but are advanced enough to teach enthusiasts loads of new tricks too. Really can’t get enough of these, thanks!

  • Brilliant build. A nice upgrade would be to use XT-60 or XT-90 connectors instead of the Dean's connectors. We use them a lot in high-current applications for RC models.

  • Next week : “Building a portable power station completely in brass”

    • Sound just a little bit dangerous /s

    • DIY perks latest video be like: Building a hyper time travelling module powered by a 80billion watt repulsor with old batteries and an old foldable phone.

    • @reggiep75 ok lix

    • Bahahhaah

    • Topnotch system What was the time invested?

  • Admire how even 'shouting' after a victory is done in a very respectful and humble tone/volume. This dude could deliver bad news with that voice and you'd thank him for saying it. Once again, lovely video/build :)

    • Man respects his neighbors. Gotta love it.

  • Looks so sophisticated and professional, not for my DIY skills! Great job!

  • Great engineering. Battery looks something you cant even get on the market , unless you make it yourself. Thank you for your work.

  • For the incapable among us: this would cost like $500 to make (+tools and dozens of hours), for the same amount of money you can buy a 720Wh camping battery on amazon. Not as good as his, but I guess that the skill it takes to make one is what gets you the extra 200-300Wh that he gets in this. Plus I suppose you'll have someone to sue if God forbid it melts down and your Yaris goes up in flames.

    • @throttle therapy the plug in has an 8.8 kWh battery while the standard model has a 750 Wh battery. It seems for as complicated as the vehicle systems are for such little gain, is it worth it?

    • @Jefferyl22 why would it need a big battery though? Its a hybrid. It has a gas motor. The battery was most used to store surplus energy and take advantage of things like regenerative braking, which is basically where most of the efficiency on the Prius comes from. Plus, the engine can generate power at peak efficiency. The newer Prius have bigger batteries but those are plug in hybrids.

    • @throttle therapy it seems like the Prius would have more battery than that.

    • Haha *among us*

    • More like $800 USD once you add all the additional stuff. The batteries alone cost over $400 USD, and thats probably not including shipping. But to be fair, it it is a 1.3 kWh battery. That's the same capacity as a second gen Prius. You could make pretty substantial ebike with this.

  • I love how he makes everything so entertaining to watch. I'm probably never gonna build any of the stuff he makes but it's so good to watch

    • I think it's because his enthusiasm is so contagious, he's so happy to be making stuff and it really shows :)

    • Just think about handling this amount of lithium battery horrifies me lol. It can be extremely dangerous without proper knowledge and tools

    • Same here. I know id probably cause an accident. He seems like an expert.

    • I share the same sentiment. I love to watch the videos, but I’m very sure I won’t end up building any of the projects. I really wish I could buy some of these builds though… the hidden desktop and artificial sun especially…

    • when i get some money i might try to build the pc built in to the desk and this as well, and some other stuff that i find usefull at that time

  • Listen, this is my second time watching this video... the layout, design, and attention is so impressive that I want to know how could I purchase a copy of this Power Station. And because I now know how this is produced, I feel better about it than any 'over the market' types that might be out there that could match it. Please give me insight on how I can acquire a copy?

  • This is an excellent project, Matt...and a very well explained video which includes info on the parts. I think you could sell kits and ready made units and make a tidy profit into the business. Standby/outside power is always in demand.

  • What an intriguing build, as usual! 👌 And your outdoor activities are priceless 😂

  • I am absolutely blown away at your creativity for some of these projects. Its not always conventional, but the methods and things you do have a purpose that suits your uses well and it gives me a ton of respect for your building. Keep up the good work. I hope to follow along to some of your perks soon.

  • mr perks achieved something many cant do *non-repetitive content* edit: thanks for so many likes lol

    • Nicely said. And he's not a dumb lump either.

    • true XD

    • this is my personal opinion, and i think every video is unique but feel free to have your own opinion ;)

    • hear hear

    • True

  • Thank you so much for making it so awesome, so beautifully done, and clearly explaining its use.

  • That power station paired with a pretty decent solar panel would be awesome to bring for camping trips or long road trips!

  • this is amazing Matt, thank you for showing. I was looking for a DIY large capacity UPS project and I wonder what would be the downside of keeping this constantly plugged to the charger and a Desktop PC constantly working of it over 240v Inverter?

  • Thanks! Beautifully explained and built. It looks like a piece of high end hifi equipment either that or a Morris Minor Traveller (the 1st half timbered car produced in the UK). Once again thanks P.S.what was the approximate cost of the build parts?

  • Never gonna build any of this, just here because I enjoy watching people build stuff with a legendarily joyful demeanor.

    • I want to like the comment because I agree. But I can't bring myself to spoil that perfect 666 likes

    • Me too!

    • Same

    • His videos are awesome arent they Even if your not going to make any it may inspire future ideas for things you have laying around rather than if going to waste

  • Thanks for the safety warnings and the visual animations of the battery charges. Makes things easier to understand. 🙂

  • I always enjoy your ingenuity into making something useful and with a bit of cleverly designed style. Just like an actual product.

  • Absolutely love this channel. Completely destroys the competition.

  • I really admire your tutorial. Your concept of caring around a mini portable powerwall is amazing! Not only that but the amount of money you are saving.

  • Man this guy has PASSION for what he does. Such quality videos. Such hard work. Even the persona he embodies for his videos must take so much energy.

  • Matt's back at it, with another brilliant thing I'd love-but will never find time-to build.

    • If time wouldn't be the only problem

  • This is just amazing! Love watching your projects. Thanks for the great video!

  • Your videos are interesting source of knowledge, and aesthetically pleasant kind of ASMR experience at the same time. This is unprecedented. Thank you and please keep up the great work! Love your channel so much!

  • I am impressed by the quality of your work and your videos! The attention to details is outstanding! Even the background of your video was amazing! I wish you a looong life, so the world can continue to enjoy your projects.

  • I must say I would *easily* buy this thing if it was available for purchase.

    • @Jefferyl22 I assume you mean amp hour and not amp. If so, 300ah cells in a 4s config would be 3.6kwh, roughly. Those are also likely LFP and not NMC/NCA cells, which is fine for solar banks, but not really useful for portable systems like in the video. You are also limited when buying at that size in form factor. Smaller cylindrical cells can more easily be rearranged to fit a specific item like the one in the video. Outside of those issues, using large capacity cells like are fine. Your other issue is on staying with 12v. While it is easier to find inverters for 12v, it isn't the best option. 24v and 48v greatly reduce the amps needed to reach a given wattage over 12v, meaning that you don't need thick cabling, as much cooling, or as big of a bms. Further, solar charge controllers are more limited with lower voltages. 48v solar charge controllers allow 4x as much solar capacity on the same size controllers. The only real benefits of 12v setups is that they are easier to set up and work better with older batteries like Lead Acid.

    • @Anthony Pelchat if it were me I would use some 100-300 amp cells commonly used in solar battery banks. It seems like if you have a whole pile of small cells the complexity of the bank is not worth it. 300 amps at 12 volts is a good deal of battery and that’s only using 4 cells. It can be brought up to 24 volts or more but I see no reason to besides making the conversion of power that much more complex. Most inverters are meant to work off 12vdc. Buck converter usb boards for charging can be had for quite cheap.

    • @Stefan Good cells, brand new, can be found for decent prices. I found the specific cells used in the video for $440. These are high discharge cells, rated at 10c continuous and 4.2 ah. Other good cells can be found cheaper. I have 21700s on my desk that can be had for $3 a piece and are high quality 5 ah cells. And Daly bms are good quality as well. You only need 40 amps for what he built. And if you are really concerned about the safety, you can find low cost LFP cells fairly easily. They would be heavier and bulkier, but you can find them just fine at under $200 for the capacity he has.

    • @Anthony Pelchat good cells pose enough risk as they are. I really wouldn't want to increase this risk further by going cheaper 🤷🏼‍♂️

    • ​@farfour You can easily find items much cheaper than that. I found these exact cells for just over $400, but you could get similar capacities for cheaper. I quality Daly BMS (without bluetooth) is only around $30 for 40 amps, which is all he is needing (that's 2000 watts). If you shop around, you could likely build something similar for under $400. Building supplies like the spot welder, cutting tools, etc would of course be extra, but you only have to buy them once and they can be used for several projects. If you are only going to build a single item this way, then it likely wouldn't be worth it. But if you think that you will build other items, then this is far cheaper than buying outright.

  • I like the additional spacer for the BMS to keep the battery stay cool. The only optimization potential I see is in the internal cooling system for the batteries. The batteries are in their own box which prevents a good exchange of the air. Maybe there could be some slits in the plates allowing more air flow directly to the cells. In the end I like the white finish which helps the batterie to stay cool even at sunny weather. I found that besides a white surface an additional shiny surface boosts the "cooling" effect of the surface dramatically. So the shiny white foil as a finish is the ideal way :)

  • I am impressed with the quality of your work. There goes to say that you really detail how to go about your projects. Well done !

  • Not only is this an amazing build but it looks absolutely beautiful 👍

  • I have been an avid follower of your channel for almost 10 years and I must say, you never cease to amaze me. Please keep up the good work!

  • The only times, he goes outside: - He has built a battery pack - He has built a comically large flashlight

    • We both know where is this going

    • @Dean No, OP said flashlight... 😂😂

    • comically large spoon next?

    • It’s amazing to here about his story and why he builds. Porn addiction is so real, amazing that he was able to abstain watching adolescent content and turn his life around with building/creating!

    • To eat spaghetti in the woods

  • You’re so incredibly good at what you do.

  • Man, I've seen a lot of power pack builds but this takes #1 spot, the build quality of that pack is off the scale. I'm really impressed, btw who are those disliking this video?

  • Beautiful design! But I think I would add a cover, to protect the exposed bits from rain. (Especially important in the UK!)

  • I'm convinced that Matt can make anything if he puts enough time into it

  • he is easily the most genuine person on youtube hands down. god bless this man

  • I love the idea of making it DIY. But, being an engineer myself, I would still rather buy one of these, if you would be willing to mass produce it, instead of making it myself. There is a lot of work involved in this, especially hell lot of tools and other apparatus. You are brilliant brother.

  • The craftsmanship is amazing! The provided current is also amazing for something of that size.

  • I really like your videos! Always well explained and very interesting DIY projects! keep up the good job. cheers from Portugal.

  • this could easily be a marketable product, with some cost reduction and a decent manufacturing process you could make a lot of money off of this. the fact that it is so small and could even be made smaller is absolutely insane considering it can keep devices powered for weeks!

  • Really cool project! Would love to see one made of graphene.

  • I love it, all are well designed, mounted.... great job !

  • Congrats man, I can safely say you're one of the best content creators I've ever seen on here, independently of topic.

  • Never had any regrets subscribing to your channel. I know I can't do anything like this but it is really interesting and fun to watch

  • This is not just high level DIY, everything he does is ART. I wish I could buy the stuff he makes..

    • @S K Yeah, honestly I'm not sure if want to mess around with something like this. I'd always be worried I screwed something up and it would catch on fire in my trunk or something. I'd still trust it more than a cheap one made in china though

    • @KingNast I suppose u can buy smth simillar, but factory-assembled, at this cost. But this bunch of li-ion batteries is really dangerous. See the news article about tesla car crash in Australia.

    • It’s amazing to hear about his story and why he builds. Porn addiction is so real, amazing that he was able to abstain watching adolescent content and turn his life around with building/creating!

    • I'd make one and sell it to you for the cost of parts and shipping, but it wouldn't be cheap. Just the batteries and management board comes to 484£ ($684 USD)

    • those are really nice batteries too. My Molicel P28A 18650 batteries have outprformed all the so called "best" batteries on several review sites

  • This is next level DIY. Great video, this stuff takes weeks of research to even put together a video like this. I'm currently running a goal zero brand portable battery. I'm planning on a battery setup for my bus and this was very helpful information. 1000ah LiFePO4 setup with 1000watts on the roof. No easy feat, but way cheaper to DIY.

  • Well done, next project you must integrate an internal resistance meter! Much more important to test internal resistance then the cells balacement.... anyway you did a good job.

  • If I were to build this the biggest change that I'd make would be to use relays rather than power switches.

  • Everytime I see a DIY percs video I imagine what it would be like meeting him at his home, not knowing his DIY skills and finding all those crazy good gadgets and then asking where he has them from. I think I could not believe he did this all by him self. I mean the technical level is crazy!

  • The quality of these builds is more like bespoke manufacturing than "DIY", yet straightforward enough to feel doable. Really cool.

    • I really want to learn how to achieve this level of polish in building stuff from scratch.

    • Yes. Bespoke electronics. That's the word.

  • Awesome content, interesting topic, nicely narrated and so pleasant to watch. :) Thanks. Cheers! :)

  • Another great video Matt. As always, explained perfectly. Thanks!

  • Dude this is perfect! I was looking for a DIY Pack for my astronomy equipment, Specifically Astrophotography which uses so many electrical devices. However, I believe I mainly just need 12V, but I'm new to this so I have do more drawing board work to see how many of which outlets I would need. Thanks for this! Then again the welders and rivet guns are things I don't have and will bring the cost up. Then again equivalent store bought versions with way less capacity are about $500. So I will def be looking into the pros and cons thank you so much! Is there a schematic that you have for this please?

    • I was thinking about giving it a go for the exact same use case as yours. But I definitely neither have the skills nor the tools required to do such a build. Additionally, this looks dangerous to do myself without having any knowledge in electrical components or soldering. Well I guess I'm back looking at retail battery packs (why are they so goddamn expensive!)

    • Hmm, well I guess i can make from the video

  • Hey Matt, thanks for sharing. A couple of questions: 1. What's the total weight (kg or lbs) of the case? 2. Can you specify which boards you had to include fuses? 3. What would you recommend if we wanted to modify the build to include the main voltage inverter inside the case?

  • I keep saying this: This guy is outrageously talented

  • omg one of my first jobs was spot welding battery packs and everything you said is so right! I used a welder that was mounted to the table and i used my foot on a pedal to actually press the welder down.

  • I love all the stuff you make. I just wish you made more with simpler materials and tools required... so much faff 😂

  • I am running out of words to describe your talent. I love this video. I wish I could be this creative. Well done. Love your channel.

  • Really high quality build. My only issue is that a build like this kinda defeats the purpose of diy. The amount of money spent on the new cells, the top of the mark bms and the overkill safety measures, along with the cost of the inverter would go into the 4 figures. With that amount, you could just buy a battery power station like the bluetti. But other than that, really top notch!

    • The bluetti EB150 is the most comparable unit, only has 45w PD output, rather than 95. It's a good option, but it does not meet all the same specs this does. Plus with this you get to say you made it.

    • He did say that this project was meant to be scaled to your use. The amount of power in this project is overkill for most uses.

  • Imagine, you're walking through the forest, you hear three beeps in the distance, several minutes later you stumble into a clearing and see Matt sitting next to a microwave happily eating pasta: 17:50

    • @Arthur Sanches Imagine Davie504 seeing Matt cut spaghetti. He'd SLAP him and call the police.

    • @Heidi Johnstone don't say that out loud, the military is listening

    • @Heidi Johnstone Then you get in trouble with all those 3 and 4 letters agencies, and you really do not want that.

    • @bknesheim maybe he can make a microwave gun, and cook birds right out of the sky

    • @DIY Perks So no you really need a microwave that can be flat packed and quickly assembled on the spot. ;.)

  • This is by far one of the best videos I have seen, clear, concise, informative. Now I want to build one, also thinking I can apply this to a bike battery that is failing.

  • Thank you so much for sharing! I wanted to see what kind of stuff goes into these portable power stations.

  • For the extra current you needed / wanted for this project, would two layers of the thiner nickle strips not have worked? The spot welder would be a fifth of the price, and the thinner nickle strips cheaper. Incidentally how much current on the thin nickle strip would it take to melt or short that out?

  • These are not DIY perks. This is next-gen stuff!! The contents are just awesome. From chemistry, physics, engineering, design just name it! I learn a lot!

  • 50 Years from now: How to build your own radioisotope thermoelectric powered ion propulsion hover scooter from a salvaged Mars rover.

    • Hahaha, brilliant 👏

    • In 100x less cost than buying it

    • @Night Stringers JUST use Margie Taylor "The Greenie" 's "Jewish Space Lasers" !!!!

    • Not if you guys keep voting blue.....

    • *from bras

  • Awsome project. Very well done with a lot of care for the details. And the final result look like this. The battery spacer / holder you used are they 3D printed ? Thanks Peter

  • Who watches these but not make them. i cant afford MOST of the components that Matt uses, but its really fun to see it in action :)

  • Great build! And good luck identifying and changing an individual faulty cell!

  • This man is the pure definition of safety and dedication

  • Honestly I'm just following the channel hoping for the day that Matt builds his own functional death star. In brass, of course.
