*Super compact and easy to carry and travel with accessories for the electric **Generater.Systems** .I was worried this was going to be bulky or hard to use.Hooks up easy and charges quickly*

Holy shit.... someone on KZfaq doing a DIY that actually researched and knows what he is taking about. That's refreshing!! I'm an industrial electrician and constantly work with 480 and 208 three phase power. This guy is spot on with voltages and Watt hours etc. Good job!!

You have a talent for explaining things where people can understand and without getting bored or losing interest

To make it optimal, we could add a BMS (Battery Management System), with cooling controlled fans, vetilation holes, with screens, and below freezing temperature shut off. Oh, and don't forget a metal box... Looks cooool! Great video! Thanks for sharing!

Homeboy you are a godsend. Thank you for sharing your knowledge with us. So grateful for people like you teaching the rest of us how to do things we would think we were never capable of.

Jehu has a real talent for teaching this stuff and you can tell he care about his audience , thanks man keep it up.

Just stumbled on this and was impressed, he’s friendly and knows his stuff. Keep it at the baby level, there is a mix of capabilities watching and some have been away from any tech work for a long time;)

Awesome job .. I love how you de-mystify this stuff .. it benefits even those folks who know, in principle, how this stuff works. One of my degrees is in EE, and I know plenty about how this stuff works, but I tend to let my imagination run wild about the possible complications, and so never undertake a project. Being able to see it actually done from stset to finish provides needed encouragement (and insight into which parts to use etc.) Please keepep them coming!

You are amazing. Thank you for taking the time to make this video, I enjoyed it immensely.

I loved the part where you explained how you can wire battery packs for whichever voltage you need! Nobody seems to know just how useful and versatile 18650's from laptop batteries are!

This panel can put out close to 100 watts kzfaq.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

Every thing said, the stuffs you're doing is what modern day heroes do. To me, you're among the unknown unrecognized global heroes in the making. Only a passion to share knowledge to empower people can make people do what you do. Godspeed!

I don't know how i stumbled onto this but im so glad i did. i cant wait to try do this!

Awesome, would love to see a start to finish portable version like charge the battery off solar and take it with you in a vehicle so you got a charge point on the go for long distance

Wow just as I was in the verge and creative time lapse of I should build my own 18650 battery pack for an eBike this guy pops up on my KZfaq news feed. Thank you my great guy! When my build is complete I’ll be sure to credit you for everything I’ve learned from you. - Abraham desde NY, nacido en Mexico! Cheers brother!

Very encouraging for a first time exposure to what it takes to produce and charge high capacity batteries at a reasonable price.

Dude, you are so impressive. This was my original video I found but then I saw your kickstarter and then that you actually have created other products... very impressed. Thanks for your videos.

Cool project, I always love DIY and people who share the knowledge. To everybody else on here, right or wrong, we should be thankful for people who take the time to do a good video and share their knowledge, even if it is wrong or we don't agree with it fully. You can either learn good things, bad things and takeway (if you choose) something from things like this. Having said that, I do disagree with a few things. First the price, you only mention the batteries, wood and glass as cost on your BOM. However, and you even link to these in the video, there are many other components on the BOM. For example, the battery holders link you provide, takes me to eBay where there are holders that hold 15 batteries for 5.99 each. To buy enough of these to hold 600 batteries, it would cost $239.60 just for the holders. On top of that, there are many other items, for example the fuses, buss bars, wiring, etc... Given that, and not even factoring in labor, I think your actual BOM is more like $600-$700 (and that is assuming you still use that overpriced piece of glass). Still not bad if you want to take on a project of this magnitude. Which brings me to another point, the labor. Do you care to share how much time it takes to pull apart all the laptop batteries, test them and then arrange/solder them all together into these packs? I would venture to guess it would take many, many days. Finally, as others have pointed out, there are things like UL listing, thermal and environmental concerns, etc... that are not factored in to your solution. I love DIY, but some things that may burn my house down, I tend to proceed with caution. By the way, if you burn your house down with something DIY like this (no UL listing, etc...) you may not even be covered by your home insurance. So, my summary, while the Powerwall is $3k-$3500, that is actually a good price when you factor the BOM, labor to build and other engineering concerns. Mike

You could build an electric gokart with that, kinda like making your own mini model S.

I was working for a delivery business and seen this workshop that had 3 of the BIG industrial power walls side by side. First time I’d seen it, asked them a bunch of questions and they bacially hadn’t paid for electricity since they had them installed, and they used tools ALL DAY, shop fans, welders, hoists ect ect…

holy guacamole! that is impressive. - I built and installed my own solar after a ton of research. Everyone i have told thinks I am crazy, including my wife, but now that i have't burned down the house, and my AC is running at 75 degrees in 105 degree weather, now they don't think I am crazy... I have considered a battery backup, but going off grid would be epic! I am seriously IMPRESSED with your work. This is my first time to the channel... and your motherboard channel. I will be spending a few more sleepless nights listening to that content you have posted.

It's all about the batteries.... weight and current vs. application capacity. II have a cluster of free 40 x 12V 20Ah UPS Led Acid batteries that I get to torment from time to time on my DYI UPS backup ideas. The other day I tried a load on just (1) single but good 12V Li-Ion, battery. So we dream every day of finally pulling off the grid and make good DIY stuff like you share with us. I can just say It's amazing the power one gets with no weigh from Li-Ion/ 18650 batteries. Thank you, Mr. Garcia for tons of inspiration, keep your nice production up : )

Finally...a video clear enough for us regular guys! Simple is always better... thanks!

Great idea....questions: 1. By using old batteries, isn't one vastly cutting life expectancy of the pack? 2. Are the batteries easy to remove/replace when they go bad? 3. Is there some visual cue that indicates when each cell quits working, to easily facilitate changing out only the bad cells? 4. And, what happens...anything adverse...by pairing cells of different ages and wear? The box could be configured to inset between wall studs, so avoid anything much sticking out off the wall surface!

Hi there, You forgot to mention the costs of a control unit and an inverter, which - of course - are included in the Tesla Unit. Regards from The Netherlands, Roelof Kingma

This is a great channel! Clear, concise, correct, cross-linked! Love it!

jehu thanks for all the great videos. I'm dreaming of a self made powerwall and your videos helped steer me in the right direction. lots of great content, instruction, and ideas!

I want to build one of these for my house 50kw. I dont know what charge controllers and fuses I would need. So I'm now a subscriber

Dude, you have an amazing channel.

Great job. If you look around you can even buy them new for a bargain and skip the tedious work of taking the laptop batteries apart. But what about balancing them? BMS? Several balance chargers?

I love what you do I think I’m going to start a new career in this industry.

Thank you to your videos I'm no longer able to find used batteries. Now they cost more of new cell!

What a nice project! All it needs is a charger now!

Shared !! Can't wait to finish my own similar project on my channel!

You could add some "ultra capacitors" across the battery packs in each box if you have room. They have huge lifespan & can source hundreds of amps, so can ease load on batteries during startup of any electric motor or refrigerator loads especially in cold weather.

AMIGO ERES LO MAXIMO ..EL MUNDO NECESITA MAS GENTE COMO ..UN ABRAZO DESDE CHILE!

A great place to get 18650's and other batteries FOR FREE is in those used battery recycling bins that are at most electronics and hardware stores, or you can ask at a recycling facility, 18650's are in everything from cordless drill battery packs to laptop batteries.

Looking forward to your video on inverters..I use 1.5kw pure sine made from server ups

Thanks for teaching and make a contribution to human kind, it is a great way to make something special.

That VW van was my first vehicle in 1976! Love it.

Awesome video, I am looking for a high capacity "whole house" UPS for computers/routers/switches etc. I wonder how I could wire a big pack to an off the shelf 24V UPS, or if there is another way.

Holy crap this is awesome!!! You're a genius!

Make your own Tesla battery !!! The glass saying Tesla is the best part. Excellent!!!

I love your work Garcia. Keep making it.

I really in love in such kind of stuff....... and like your channel and the idea. awesome work bro.

Nissan had the idea of using used packs for grid storage. Just not home grid storage.

Great info! Love that microbus. I had a '59 23 window with the factory electric fan, and clock. No gas gauge though. Wish I still had it.

thanks for showing us. This is so exciting! I'm totally gonna try it now :)

You might consider a fireproof enclosure for that contraption... you know, instead of wood.

Awesome video man, can't wait to see part 2! Would be cool to see some 18650 safety tests like fast current drains and over voltage charge and shorts etc.

Your videos are inspiring to watch, I have learned so much from you. Thanks mate.

Enjoyable video and good info. That said many folks are not aware of how easy it is to refurbish cordless tool batteries for peanuts. For the price of a replacement battery pack you can get 100 cells on ebay.

Here, have a subscriber. Former Green Energy/Battery Backup/Inverter guy here. Love your stuff.

Your videos are amazingly cool, keep it up👍

Cool. Did not know there were inverters that would work as charge controllers. That's great.

Excellent tidy clean work. I learnt alot from you. Thanks for sharing.

Decent video though not for the uninitiated. One note, you stated Nickel Metal Hydride (NIMH) has a memory issue if not discharged fully before charged, that's actually Nickel Cadmium (NiCd) that has that issue hence their obsolescence and NIMH being used widely still due to their long life and lower cost than more advanced batteries.

Great project.. Its got me thinking. I don't know why you included the price of the wood in your project costs but didn't include the wires, wiring connectors, and immobilizer. I would imagine that would add some significant cost. $100 for the glass?.... well I guess there is a place for form over function, ( a piece of scrap metal painted with good paint and sticker would have achieved the same effect). I look forward to your next video.

So basically the scheduling was like waiting for the guy from comcast to show up for 1 visit . Great breakdown thanks for sharing.

Bro. You’re a goddamn legend. I will now proceed to see all your videos as I attempt to make a solar charging station on my e-Golf.

This is great, I'll probably make one myself. Have you considered making kits for people who want to build stuff but don't have the time to build from scratch

100$ for glass... you could buy more cells

Brand new subscriber, found this gem today. Thanks for your time and knowledge.

VERY informative and well done video! Got me curious about making one for my camper and my vehicle! Thank you very much!

Hi i'm interested in this power wall. If I want to charge this 600 battery pack the total pack capacity will be 1200 Ah and what is the most suitable charger to buy? As far as I know PowerLab 6 Charger can handle only up to 360Ah!!!. Please educate me. Thanks alot friend.

I really want to do this. Thanks mate!

I love you. You are the future. Got here because of vice and you inspire me to learn about it and know about it because it’s something about the future we r gonna have to deal with

Love your work buddy. Thanks for sharing!!

Genial, from the island of Puerto Rico. I like to have one. Good lock

What about the BMS to balance charges and loads? Did I miss something?

awesome video bro, keep up the awesome work of teaching skills to peeps. This is what yt was made for.

yeah i was thinking about devoting my life just to follow you all day around..a very good video.

What about cooling and ventilation? Tesla has an active cooling loop to maintain the correct temperature. What about redundancy? Tesla has overcapacity in the batteries to survive with battery failure. What about a battery management system? What about fire saftey? Lots of things to consider beyond just bunging a few laptop batteries in a box.

I'm confused, did you go with 3s for 12v? 3s is really 10.8v or 11.1v. Most 12v inverters shutoff at 10.5v, meaning you probably will only see about a 50% capacity usage or less (depending on load) if you go with a 12v inverter. 24v inverter with 7S is a far better choice as the voltages are completely compatible.

Really awsome videos man, I'm learning a lot with them, keep it up!

doode, thats amazing! Thats so much better and cheaper than teslas powerwall, crazy low price!! keep going with your nice work!!

You dont calculated he charger, the connerctors, the cable and the AC module. A glasswall like this costs in Germany only 19€.

Hi Man!!! congrats! how many cicles you can use this powerwall?

Little 18650 or whatever have anywhere between 600 up to 2000 cycles Ignoring anything about BMS is bad But Bright idea and great DIY I'd really love to see this project continued

Thank you! Refreshing info. I live on a boat and power can be an issue but with info like this lots of help i just suscribed and again thank you!

Sub, i like how you explain it in layman term...

You’re the man! 🙏🙏🙏🙏

great to build into the floor of a tiny house.... awesomeness 😀👍

I think I have watched this video 10 times now very instructional

Crazy irony: As soon as you have 600 batteries holding all your electric juice in box in your garage, you work to turn your DC into AC... To travel only A FEW FEET!!! A better investment of time would be to remove the numerous components in your various electric appliences to deal with the assumed AC input. The initial breakthrough of AC by Tesla a 100 years ago was to make electricity transmission possible. Now that solar panels have come so far, no need for power transmission lines. So, no need for AC-DC conversion portions of almost every electric circuit in every appliance (and the complimentary inefficiency!) Not only live on solar power, reduce the needed electric need by removing the DC-AC converters all over the house.

Really cool project and good work. You're giving me fuel to keep going with the planning of my own project to make a vehicle (Kit car) or convert a vehicle with the view of using a "dual" home battery for myself. By dual I mean a permanent home cell that is given extra capacity when i plug the vehicle into the system (the vehicle wont be my daily use vehicle). I will keep watching and developing a list of questions as i go through your videos. thanks for looking forward.

You are fantastic, serious and on the topic!

this deserves way more views

my god. how long do you make it?

lol lots of people calling you out on balance wires, FYI guys This guy does know what hes is doing, he might not want to make a power wall for real and is just showing us how it can be done, i would like to see a working power wall though.

You need BMS, if your adding solar panels, you should also invest on MPPT charger controller. The inverter should be the size of whatever you plan on running continuously, take in consideration the surge power and it should be pure sine wave inverter. Good luck

While some commenting apparently don't like your work, overall it's great that you're sharing info. Personally, I'd rather spend the money you did on glass with logo on better (or new) batteries, since old ones have already spent some cycles and will have to be replaced sooner than later. A plain piece of glass is cheap, and labor or fire isn't. Overall, thumbs up and nice job.

Liion has been known to explode on infrequent occasions ; suggest you put it outside away from your house so your insurance is still good for the house. Nimh is NOT known for explosions and while heavier is not a factor because its not moving (in fact Ni-Fe might be best of all because space and weight are not players and Ni-Fe has been known to last 100 years). oh yes, you mentioned memory effects with nimh, actually its more the nicads that have that problem, nimh is not known for that.

great vlog bro

Brother you are a teacher, a skilled craftsman, a entrepreneur, a artist and all around model American Man! Thank you... i have subscribed... going to your channel now to catch up on all your videos! One request.. please name the components ("these guys") verbally or subtexts, either one would be fine.

Dude you are awesome!! Idk how to do all these but I am very interested and hope one day I can follow what you do man...

Aloha Jehu, this video is 4 years old. Do you still recommend using this method to build a power wall? Or has the technology advanced so much that you recommend something else? Mahalo, from Hawaii!

How much a EBOOK ? IN THIS CHAPTER (EN ESPAÑOL) ?

omg the struggle was real back in 2015! ordering laptop batteries and extracting the cells. talk about labor. now you can just buy the better 21700 in bulk on Alibaba for like $1 per

Helpful, thanks. How many continues amps can I draw safety from one battery using a 18650 with 2000mah.
