600,000mAh DIY Power Pack build 

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!

This is a hell of a vape mod.

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!

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.

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

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.

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

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.

now try to get that through airport security

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

"Bomb has been planted"😂

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

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

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.

This episode rocked. Thank you.

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

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?

Can't wait to start my own diy powerwall

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

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

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

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

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!

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

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.

Love the video & the collaboration. I look forward to seeing more like this.🇵🇷

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

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

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)

This channel is amazing, and this man is a genius!

holy crap jehu that is well done! Great kit

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

Jehugarcia this is a great video thanks for creating this channel with its great content you Rock...I'm going to try to build this it's very interesting, you inspire people great work...I hope my talent show channel can reach people someday like your channel does every day...Keep up the great work you do....A+A+A+A+

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?

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

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

This can be great for camping. :)

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.

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

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

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

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

Nice build! Well thought out.

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

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

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

Excellent build, Jehu.

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!

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

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

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

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

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

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

Great blast radius too!!

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

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 :)

Awesome video! This is what youtube is all about. It's why I love this channel and it's why I wished I paid better attention during my university physics II class. Amazing how he was able to fit a the bulk of a semester worth of knowledge into 15 minutes. I get it now! Thanks;)

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

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

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

That look amazing I love it .

Good for range extender/charger for EVs! Nice you may need mot but again, nice concept. Good for camping too!

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

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

The giant😱👍👌😍loved that ...

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

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

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

Gracias por el diagrama esquemático ecléctico. Es de mucha utilidad

Love the telecaster in the back

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

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

Love your VLOG Jehu! Sascha (VW)

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.

me encantan tus vídeos. lastima que no tengas un libro en Español

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

really clean nice man!!!

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.

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

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

Thank you Jehu!

Jehu, strong strong work!!!!

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

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.

Saludos Jehu, gracias por el video

New subscriber, great content. Thank you.

But can you recharge it with solar energy?

I dont know how I can fit this case into my backpack.

Wow bro really awesome video I appreciate your hard work thank you 👏🏼

Super bomb value is here If with Note7

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

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

This is freaking awesome

That’s badass!

12:31 This isn't a hall effect sensor...

And wha is a real usage of it? Why you not using a car/bus acumulator for 1/10 of price?

Cheers Jehu!!!!

Loving your channel :)
