If anyone wants to know the price, it's (excluding shipping and tax) Case - $74.47 Battery Modules - $22.72 x 14 = $318.08 BMS - $49.00 x 2 = $98.00 Batteries - $730.00 Total about $1220.55 + shipping/tax/fees

When I saw your powerwall boards I wasn't the biggest fan because of the added cost and "complexity" but I knew where you were coming from in designing them and getting them to production.... but this is a PERFECT example of it's benefits, how cool is that, and in a few years you can replace the cells if you want to upgrade... I love it!

Nice system! Tip for the standoff posts - if they had left and right threads, then you wouldn't have to disassemble the entire pack from the end just to change a cell in the middle!

This is a hell of a vape mod.

Nice project! I had to build my own battery suitcase too. I am an astro-photographer and I've got to have enough power for 2 cameras, peltier cooler, a laptop and heavy tracking mount to last for 2 nights in a row in a middle of a desert. I couldn't find such a battery off-the-shelf so building one was my only option.

Nice build, some notes: make sure to point out that the 'bare' cells were covered in transparent shrink wrap or some people might get the wrong idea here, you'll need some insulation between the modules in case a battery every shakes loose (for instance: because the suitcase is dropped), you need some hard foam and softer foam inside that to protect the cells if this is used in mobile/vehicular applications (and given that it is a suitcase that should be assumed), and you should use silicone sealant around all ports for plugs, displays and so on to stop moisture due to condensation from creeping into the case. I'd also use thicker wiring in case of 100A, what you have there might just live through that but given the fact that if it doesn't it is asking for catastrophic failure it is better to use something a bit thicker, and to tie it down properly. Nice choice of case, self isolating so that at least avoids the mistake many of the people building transportable packs make (they use a steel case and then don't properly line it causing serious issues in the longer term). How has it been holding up over time?

"Bomb has been planted"😂

You're giving me too many projects to do, Jehu, I'm trying to save up for a holiday!

now try to get that through airport security

Take this to school and you’ll be the “plug” for charging phones.

No thanks. I'll wait for the 600,000,000uAh version, which will be way more impressive. Until then, my 600Ah battery will do me fine.

I'd recommend covering the stand-offs with heatshrink insulation. That's a lot of current to have on naked bus bars floating around like that.

600,000,000uAh !… 600,000,000,000nAh !!!… 600,000,000,000,000pAh !!! **explosions**

Ive been in construction engineering for the vast majority of my career, and I find this stuff interesting and at the same time amazing. Recently I have been looking into battery packs, alternative energy etc. Hoping to install my first solar panel soon to feed a specific part of our house. Want to test the system by utilizing the energy exclusively in that area. Built my first power “go box” this past week.

I never know exactly what you are talking about because I am learning but what a great guy to learn from. I enjoy all your videos.

Its satisfying to see the cells get plugged in the boards.

Why do you gotta wrap the 18650? To insulate them?

first thought about the heat that would be generated then realized this could explode. bomb tutorial? i think it has potential

I am sending you this request because you impress me, so many well meaning but incompetent people make these videos. You are a good builder, safe, skilled, and practical. Not to mention a great soldered. So here goes.... Can you design and prototype a device to test and verify batteries before taking them and assembling the battery packs. Something to cycle test the batteries before assembling packs. Thank you for all the great videos, Bill Gargan

Awesome work. I been thinking of doing this to emergency power my 12v HAM gear.

Your 7s PCB is great. You should do a LiFePO4 PCB for 24V and 48V systems as well.

13:00 there's a kind of regulation: Never switch negative! ˙ ͜ʟ˙

This is a perfect Tour Trike Power solution. Can charge the Trike fully in a few hours and have enough to power small things. Def gonna make this on my down time. Cheers!

“Why isn’t there a suitcase battery?” asked the same people who wonder if you can bring an anvil in your hand luggage.

Man its alot cheaper than I thought. Makes me want to make a 12v version for my sailboat.

You have finally answered my prayers!!!! Thank you

Nice tutorial considering to build a smaller version of it. It's good but you get pylontech 3.5kWh with 48V peak 73A, sustained 37A in a 19 inch rack with handles for $820.

You are the king of batteries. Put Wh's in the title instead of Ah which tells nothing without knowing the voltage.

Nice intro : "Hey .. let's talk about batteries" :D

Can u show us how to connect a solar panels to this??

I don't know why but this is my favorite build that you have made

Awesome job with the video, very well done, thanks for all your time and work you put into this video segment.

That amazon basics case isnt cheap lol. Might as well go with a real pelican case while you’re at it

I would make above the cells themselves a passive radiator with think copper heat pipes that will go between 2 rows of batteries and you open the lid when charging or discharging to dissipate the heat and when you transport it you have it closed and weather sealed , and also heat indicators and switches to not allow the pack to overheat or underheat allowing a heating element to be powered and heat the heat pipes if you are under 5 degrees celsius.(i see he has room for that in that case and if not we go 1 step bigger)

I love how the screws wich mount the batterys to the case are powered. The Screw on the left of the handle is GND and right one is positive

Nice looking design, but I see losses and risk of fire. 1. The fact that it is just inserted in battery holders and not directly soldered is the first accident waiting to happen. Especially for a portable unit which might be moved around continuously. No matter what metal are the contacts made of, a random spark will build very high temperatures very quickly. 2. Only one fuse per bank, instead of one fuse per battery. If only one battery shorts, it will receive the discharge from all the ones in parallel with it, which will surely be hundreds of amperes causing it to explode or start a fire. 3. Low amperage bus wire and on top of that, crimped to the connectors instead of soldered. Crimping may create loose connections more times than you think. Also, this is about very high DC currents, which will need large diameter wires. For its most part, a DC current runs in the skin of conductors, needing larger diameters for the wires. The same as the "skin" effect when an AC current faster than 100 KHz is driven through a conductor wire. I know that a lot of money and parts were spent on this and the final product is beautiful and nicely organized and I also like the looks of it, but I think you could be more thoughtful about security and efficiency on this. I wouldn't store it anywhere inside my house when not in use. I like several of your projects and this critic is constructive. It would be sad if someone follows your guide and ends up with material or health losses.

Out of curiosity. Have you done any vibration or drop testing with this? I am thinking if I were off road and it fell off the tailgate how would it hold up? Not talking any crazy 10 foot drops or super vibration just normal transport in a vehicle. Love the build!

Anything about temperatures? how thermal issues? How long do you need to charge it?

Just finished Ben's video, and while I really liked seeing 2 of my favorite alternative energy gurus ( You and Will) working together on a video, I don't really agree with Ben. I believe your battery bank can (and did) work as a gas can. The idea behind having a "gas can" is (Once running out) you have enough to get you to a fueling station, I feel your battery bank would accomplish that. Just my take, look for to more of your great videos.

Nice shirt! PWR 2 PR - waving a hand to another VW enthusiast from PR !!

this would be a hell of Vaping Time !!!! :D Charging that beast would cost in Germany ~ 0,65€

Just imagine walking through TSA with this. Tsa: how many maH you carrying. Me: just a little over 600 thousand.

those modules looks like it would be real easy for a cell to come out of. especially is a portable case that will get banged around

While it certainly doesn't hurt, it isn't all that important that cells in parallel be the same voltage so long as each parallel bank is the same voltage as the other, so that all parallel banks (or cells) connected in series are at the same voltage. Cells connected in parallel will naturally even out. Slowly during rest and faster during discharges, and should mostly do so during the initial discharge, which is a good idea to do prior to a recharge so as to minimize load on the balance fets and resistors(if you have larger variations) It's much more important to ensure each parallel bank in the series link is precisely the same voltage, which can quickly and easily be achieved by swapping out individual cells, without unnecessary concern.

Can't wait to start my own diy powerwall

For an *Aeroplane* to fly, how many of these suitcases will sufficient.

Jehu excellent video , and powering does Tesla was awesome ... Tesla Gas Can .. lol ... ( Latin Power , si se puede !!!)

I love your channel. It has inspired a great many ideas in my old brain. As I’ve suffered a couple strokes I tend to ask for clarity a lot. My math also sucks so let’s struggle through this together. 14 boards @28 batteries each is 196. And 196 x 3000mah is 588000mah. So 588000mah is 588ah x24v = 14112wh. Meaning that the battery is 14.1kwh if I didn’t miss something. Please let me know if I did as I want to be sure of how to figure my future build! Thanks for all you do for all us diy folks out here. Wait a second! 196 cells, 3.7v 3000mah/3ah, 7S 28P, 15A max discharge rate, so 24v 84,000mah/84ah. Does 15A continuous = 360w C, and since 1w @24hrs is 24wh, then 360w @3ah is 1080wh, multiply that by 28p and we get 30,240wh. Divide 32,240wh by 24v for a 1260ah potential. Don’t let your battery sag 🤪

less than 22W 32" LED TV ? where can i find one?

Great video, thank you. 600,000mAh = 600Ah, times 24V = 14400Wh = 14.4 KWh. Please clarify.

Looked fun, very fun. Personally thou i would have gone with something like s168 or 32650. No need for pcb's & holders everywhere eating space. But good job, looks awesome.

Put in a cell backward once on a parallel bank. The spring for the - side. I scrambled half second got it out...freaked me out it lit up like a lightbulb. Unknown brand blue wrap 2000 mAh cells. I'm sure u have some crazy bench stories man...HI VOLTAGE

Nice going. You should be able to plug a stranded car on it and drive to the next charger point...

Hi mate. Love your vids. Keep them coming. Love from Australia

This episode rocked. Thank you.

If my math is right, that's equivalent to 1.575 kilograms of TNT in terms of energy. That same battery pack could also charge my phone's battery 120 times. My moto E4 plus phone battery is relatively large, so it could recharge other phones even more. Lastly, to maximize battery life, try not to let it go below 40% capacity and, if you're really daring, not above 80%

Hold my Beer, My turn to try this! love it. BTW

Hey you forgot to install a countdown timer 13:55 :)

Very nice build, my only concern is you have live screw terminals on the outside of the case which could potentially be shorted

Yep, what was said re ensuring correct polarity and it's importance I can second for sure, I had a stray pinhead sized drop of solder land with pinpoint accuracy onto of a 50% charged 18650 inturn shorting just ONE cell out.... HOLY COW!!! I've never seen anything like it, it took off like a Catherine wheel wizzing around the room at high-speed spitting flames, sparks and white hot ash over the living room in a blur of fury, landing behind the fridge after finally coming to a stop a full 30sec later, when I finally found it it had burnt a hole through a full thickness floorboard and is now somewhere under the building..

Hey Jehu - Quick question, how warm did the case and battery get while discharging (9A) when charging the Tesla? Do you think it needs some sort of cooling solution or was it fine? Great video. Love your channel and keep up the good work. Cheers from Australia :)

Very like you video? thank's! How to charge such a kit from 220v?

Thanks for your videos Jehu, hello from Puerto Rico...

“Mr. President... here’s the Nuclear Football” ?... oh wait, my apologies Sir, that’s my camping 🔋 battery.

Why not 600 million microamp-hour? I think this is a more appropriate unit.

Super Awesome Build! But I think that your mAh Calculation is a little off. It should be more like 85,000mAh. Since you had a 24V system you had 7 cells in series to get that voltage, but Ah don't add in series, only the voltage does. So you essentially have 28 24V 3000mAh batteries in parallel, 28x3000= 84,000mAh @ 24V. Which then gives you 84Ah x 24V = 2.04kWh.

Dude you deserve more viewers 🤬🤬🤬🤬🤬🤬

Hi there amazing project but i have 4 big issue about safety and usability: first: the 2 main connectors red and black are in the worst place ever: as u move the case somewere u'll hit everything in the path; SEcond: main switch is hidden inside, so u have to open to turn it off... and as u open u have all the terminals exposed. a spill of water and u'll have a catastrophic result Third: there is nothing that split the external case from all the component, u just place em in the case.... if the case falls on ground.... it can pearce itself with those blocks moving 4th: how it cools? on charging\ discharging there will be a lot of heat from batteries. I really like the power bank case, i dont have 2000$ to play with, but what about those 4 points i marked? Do u considered ? Thanks for your attention, best regards!

What happened to the parts list "In the description"? All I see is "People and Blogs"!

Wow you scaled down and explained this video that anyone can easily understand

A gas can for your Tesla...now THAT is a great tagline!

A great video. Since I don’t have the time to research and source parts, I will be purchasing a kit from you soon. Thank you.

If this was sold as a kit approximately how much would the components cost

This can be great for camping. :)

I love this concept reguarding being able to swap out bad cells. I would love to see a more modular system with sacrificial battery bay's so if something bad happened your not out BMS and support circuit boards. maybe have some sort of cell management console through your cell phone via bluetooth?

great to see that their re all kinds of smart individuals; great job Garcia.

Is that DIY Solar Power with Will Prowse in blue shirt?

'Hey, let's talk about batteries...' I AM SO SHOCKED. :D

That right there is huge. You could have a bank of these and if and when they need servicing you simply unplug it from the bank and remove it for servicing.

Maybe you could make some camper van battery based on that system? So it could be charged both from 12VDC car alternator and solar.

So how come this wouldn’t need a cooling fan? Doesn’t produce enough heat?

Go to harbor freight for the case it is half the price and very good quality

I love how he’s really explaining it like he’s walking you thru while you’re doing it yourself like bruh no body about to drop like $1500 on some portable charger

Wow, that was so weird hearing Daybreak from Electric Mantis playing the intro on repeat like that. Kinda blew my mind... haha

The title is confusing and wrong (click bait indeed), your battery is not 600Ah, that would be at what voltage? at 3,65v exactly but it is a 7s system not 1s so at nominal voltage 25,2v its a 87Ah battery. You confirm that by saying its a 2,2kWh system - obviously :P

would have been easier to say 600Ah :) Another great video, what was the final build price?

car batteries be like "am i invisible to you?"

These Sony are very powerful so be really careful with them. Also the box should have pressure relief valves because if they blow up, you don't want them airtight as it becomes a bomb.

But can you recharge it with solar energy?

Damn, everyone thought I was crazy adding four 18650 cells to my phone.

I understand the sequel being Tesla-centric, but have you thought of trying this on something less thirsty, like maybe a LEAF?

Dang glad I looked thru the comments, yinlong Batts all the way.

What was the final price of the build? Great video!

So what is the overall cost of making this unit with all the parts included?

Jehu, thats a beautiful battery and you've made the process of building it very easy. The big important question that no-one seems to be asking is "What's the best way to charge this beauty?"

You have my attention on this, but I would like a 12vDC output from it. Are the control modules in this programmable to output a desired voltage, or would it need to be wired internally in a different way?

This powerbank is my dream.

Hold on, those standoffs carry current right? What about the screws that go through the side of the case? Are those not isolated?

Super cool, if you have the money!

Great video Jehu and the music was in my head while i worked, so cool!
