And increase that price by 40% if you are using Australian pesos to buy everything (And add a few hundred more for shipping since Americans love charging stupid shipping prices) then add another 10% due to Scott Morrisons bullshit tax

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!
Nice project! I had to build my own battery suitcase too.

@@ddxfs Hi, I had 4 e-bike batteries lying around So I made a case for them from an old toolbox. Added several dc-dc voltage regulators and plugs for different gear. And it held on nicely for 2 nights in a row. Funny that you wrote it today. It got stolen yesterday from my roof observatory together with almost all my astro gear. (
@@ddxfs Thanks, i'm still in a denial stage. ) We have a rather small astro-community in my country. And everyone knows my gear, if it will pop somewhere, I'll know.
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?

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.
As an electrical engineering student. Don't believe the free energy stuff, and make sure you put in the correct fuzes. Don't cheap out on solar panels, as cheap solar panels will die before the savings turn into a profit. Do the calculations beforehand, as an engineer you should be able to do the simple maths. Just make sure your circuit is fault proof, and under no circumstances work on the system while power is on it(breakers are awesome for that, even in different parts of the circuit) and don't leave any wires exposed, always check that, it happens to the best of us. And last up, don't cheap out on the mounting for the panels either. Panels can easily be moved by the wind, which is not a fun time when they fall and crack, that's something the person who installed my parents' solar panels fucked up.

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!
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?"
how long can it power my inverter window type aircon? i will only opened my aircon 8 pm to 7 am in the morning for the first day.. how many days i can use it?
But every powerpack manufacturer uses mah to describe capacity. If you are above average you should be able to figure out how much capacity this has. But if you are an average joe with a 10,000mah power pack, then you also can easily figure out how big this battery pack is compared to what you can buy.
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.
get a solar panel and a charge controller charge for free :-) my balcony is full of solar panels so it is possible to do in a apartment block, just dont make them to visible
Hi Jehu I was just thinking just wondering if you can help answer this simple questions, can you build a Tesla supercharger for home use, I have seen Tesla supercharger on the road that can charge a full charge of Tesla car for less then an hour second question does this supercharger damage batteries?
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.
They actually appear they are in 7s 2p configuration, thus (each board) creating a 24v battery that has a capacity of 6000 mAh(3000 mAh per side). The video is confusing, but if you think of it as 14 (boards) batteries that are paralled together 6000 mAh each, you come up with 84000 mAh, which would be equal to 2016 Wh @ 24v... Now that makes more sense
So if one is attempting to build a solar generator to run his RV and other things could you make your battery following this method. or r u better to buy one
@@ThisIsInput The fasteners sticking out the side are. If those are not isolated and the edge of the case with those sticking out hits something conductive, sparks would fly.
Yes I have two electric troller.motors. i am going to build a suitcase battery when I find the right amps needed so I can drive it with a battery for a few hours at half speed. That will put me on course to keep building electrics for my canal and a few lakes too. I built my own camper flat bottom boat. If this works then foiling is next!!

@@thesmoothgoat Aparentemete are two 7s in parallel but it is difficult to understand, I would like jehugarcia to separate or divide it to be able to do it in two steps. Excellent projects Greetings.
@@arizarturo I know exactly what he did its not difficult at all. I been following jehu for a while now and completely understand everything he does. I have built my own 400ah 18650 mini powerwall working great. My point is for simply charging small devices a 12v system would be better... a 4s system is the way to go for this.
Be advised: 12:57 the wiring shown of several of the XT90 connectors implies the polarities are reversed (cell negatives connecting to cell positives).
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 :)
I agree with your sentiment, but it's mostly the fault of the manufacturers, who have gotten people accustomed to 30,000mAh USB battery packs, rather than simply writing 30Ah.
You should place a piece of foam between modules. It seems like there is a small gap between there, what if the power pack get a hit and a cell do not stay in its own bay ?
Well spotted, this is indeed an issue. Still, this build is lightyears ahead of most pack builds out there, even if it is a bit more expensive at least he's doing it properly from an electrical point of view. Some of the stuff out there is essentially telling people how to start fires. The number of BMS sense wire nightmares out there is not to be counted.
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.

4. The screws mounting the battery packs to the case are live and poking outside. Doesn't take much to short them to anything conductive outside the case.
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.
I think there are so few battery cases on the market is because you buy the thing to have power while traveling... but such a big battery isn't allowed on airplanes... so what is the point than?
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'm copying and doing this project exactly the way you are presenting it and already in 4 weeks now, and finally the inverter, can I use a DC12V inverter to convert to AC220V? Or should I but a DV24V inverter to AC220V?
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..
You mess with unprotected 18650's at your peril. This is a very nice build but mechanically I'm not too happy with it: cells can shake loose and short out with neighboring cells, some of the cells don't even have shrink wrap on them and there is enough weight here that it will probably self destruct when dropped. Nice concept but it would need a lot more work before I would consider it safe enough for replication. The hard case itself is not enough protection for a pack like this, you'll need shock absorbing lining, isolation, moisture sealing and so on.
where did you buy those green wraps from? i know you can buy them from anywhere but those green wraps you have seem to match the right green as sony use and i would like to buy them?

can you please make a video for cinema camera battery pack? Like anton bauer or blockbattery type (pelican cased). ive been looking everywhere but cant really find instructions
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!
Jehu excellent video , and powering does Tesla was awesome ... Tesla Gas Can .. lol ... ( Latin Power , si se puede !!!)
Hey you forgot to install a countdown timer 13:55 :)
🤓
And more colored wires to make it harder to kill the timer
@@HDestroyer787 and add the pulsing beep sound :)
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?"
Charger.

@@jehugarcia :p yes, but not just any 24Volt charger, are you and I assuming people wont put a 24volt lead acid charger on it?
No problem, this is actually a 24v battery
Man its alot cheaper than I thought. Makes me want to make a 12v version for my sailboat.
just converted my sailboat to electric. I needed to go with a 48v system for my 36' boat.
So to charge this batter bank just connect them to 24V solar panel????
Can't wait to start my own diy powerwall
Very nice build, my only concern is you have live screw terminals on the outside of the case which could potentially be shorted
Something like this will surely have short circuit protection
Hold my Beer, My turn to try this! love it. BTW
Awesome job with the video, very well done, thanks for all your time and work you put into this video segment.
If this was sold as a kit approximately how much would the components cost
Probably a little over 1k depending on where you get your parts you could be
+\- a few hundred
how long can it power my inverter window type aircon? i will only opened my aircon 8 pm to 7 am in the morning for the first day.. how many days i can use it?
So how come this wouldn’t need a cooling fan? Doesn’t produce enough heat?
Li-Ion should not get hot in use, if they do you have problems (and I hope your insurance is good).
referring to mAh for battery size is like using inches to describe speed. I'm moving at 600,000 inches.
But every powerpack manufacturer uses mah to describe capacity. If you are above average you should be able to figure out how much capacity this has. But if you are an average joe with a 10,000mah power pack, then you also can easily figure out how big this battery pack is compared to what you can buy.
Great video, thank you. 600,000mAh = 600Ah, times 24V = 14400Wh = 14.4 KWh. Please clarify.
Jesus Bermudez It isn’t “times 24”. You have to take the cell voltage which is about ~3.7V. So 600 * 3.7 = 2.22kWh.
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.
this would be a hell of Vaping Time !!!! :D
Charging that beast would cost in Germany ~ 0,65€
get a solar panel and a charge controller charge for free :-)
my balcony is full of solar panels so it is possible to do in a apartment block, just dont make them to visible
@@georg841984 this would cost me much more money to buy than i spend for electricity
Hi Jehu I was just thinking just wondering if you can help answer this simple questions, can you build a Tesla supercharger for home use, I have seen Tesla supercharger on the road that can charge a full charge of Tesla car for less then an hour second question does this supercharger damage batteries?
Yes anything is possible but you need access to proprietary Tesla tech and a 100kwh battery pack capable of 200kw output, at least
Hi mate. Love your vids. Keep them coming. Love from Australia
holy crap jehu that is well done! Great kit
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.
They actually appear they are in 7s 2p configuration, thus (each board) creating a 24v battery that has a capacity of 6000 mAh(3000 mAh per side). The video is confusing, but if you think of it as 14 (boards) batteries that are paralled together 6000 mAh each, you come up with 84000 mAh, which would be equal to 2016 Wh @ 24v...
Now that makes more sense
So if one is attempting to build a solar generator to run his RV and other things could you make your battery following this method. or r u better to buy one
Hold on, those standoffs carry current right? What about the screws that go through the side of the case? Are those not isolated?
The case isn't metal.
@@ThisIsInput The fasteners sticking out the side are. If those are not isolated and the edge of the case with those sticking out hits something conductive, sparks would fly.
Great video Jehu and the music was in my head while i worked, so cool!
Why not 600 million microamp-hour? I think this is a more appropriate unit.
He wrote 600.000 mAh because most powerbanks are messured in mAh
Yes. It's dumb.
I've would have used 2,16 trillion microampseconds myself.
Just saw that someone else made a similar comment 2 weeks ago. Didn't appear on my first visit...
Yes
I have two electric troller.motors. i am going to build a suitcase battery when I find the right amps needed so I can drive it with a battery for a few hours at half speed. That will put me on course to keep building electrics for my canal and a few lakes too. I built my own camper flat bottom boat. If this works then foiling is next!!
So what is the overall cost of making this unit with all the parts included?
Total about $1220.55 + shipping/tax/fees
This episode rocked. Thank you.
How do you charge this?
in order to charge that you need to have a Wardenclyffe Tower :)
You have to replace the battery’s :)
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;)
What was the final price of the build? Great video!
IT'S A SHIT LOAD!!!
Jehu needs to chill with all these expensive builds, were not all on his level, we're not all making that youtube money.....
@@thesmoothgoat Aparentemete are two 7s in parallel but it is difficult to understand, I would like jehugarcia to separate or divide it to be able to do it in two steps. Excellent projects Greetings.
@@arizarturo I know exactly what he did its not difficult at all. I been following jehu for a while now and completely understand everything he does. I have built my own 400ah 18650 mini powerwall working great. My point is for simply charging small devices a 12v system would be better... a 4s system is the way to go for this.
~$1500 USD
1300€
Be advised: 12:57 the wiring shown of several of the XT90 connectors implies the polarities are reversed (cell negatives connecting to cell positives).
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 :)
it would be intereting to add a PC liquid cooling system to it.
Thanks for your videos Jehu, hello from Puerto Rico...
What happened to the parts list "In the description"? All I see is "People and Blogs"!
Is there a reason to why the pcb only fits 7 cells? Thinking about extending it to 8 cells using the same idea but extending the pcb by 1 cell.
24v
would have been easier to say 600Ah :) Another great video, what was the final build price?
I agree with your sentiment, but it's mostly the fault of the manufacturers, who have gotten people accustomed to 30,000mAh USB battery packs, rather than simply writing 30Ah.
@@gabehumphreys2433 маркетинг
Even though it's not actually 600AH
Its only 91AH since it's a 24V battery not a giant 3.7V battery
@@mwbgaming28 Holy shit you're right. This guy is a fraud
@@mwbgaming28 i dont think that is how it works
You should place a piece of foam between modules. It seems like there is a small gap between there, what if the power pack get a hit and a cell do not stay in its own bay ?
Well spotted, this is indeed an issue. Still, this build is lightyears ahead of most pack builds out there, even if it is a bit more expensive at least he's doing it properly from an electrical point of view. Some of the stuff out there is essentially telling people how to start fires. The number of BMS sense wire nightmares out there is not to be counted.
Wow you scaled down and explained this video that anyone can easily understand
Men, I really want to build half of this bank. How can you help with details of the materials and methods. Thanks
Very like you video? thank's!
How to charge such a kit from 220v?
great to see that their re all kinds of smart individuals; great job Garcia.
Whats the voltage of the battery pack?
24V
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.
4. The screws mounting the battery packs to the case are live and poking outside. Doesn't take much to short them to anything conductive outside the case.
Just imagine walking through TSA with this. Tsa: how many maH you carrying. Me: just a little over 600 thousand.
Ok so I have 36 6000mah lipo pouches how should I go about charging them and protecting them ect I need some help
Is that DIY Solar Power with Will Prowse in blue shirt?
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.
Nice intro :
"Hey .. let's talk about batteries" :D
I think there are so few battery cases on the market is because you buy the thing to have power while traveling... but such a big battery isn't allowed on airplanes... so what is the point than?

Love your VLOG Jehu! Sascha (VW)
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'm copying and doing this project exactly the way you are presenting it and already in 4 weeks now, and finally the inverter, can I use a DC12V inverter to convert to AC220V? Or should I but a DV24V inverter to AC220V?
Nice going.
You should be able to plug a stranded car on it and drive to the next charger point...
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..
You mess with unprotected 18650's at your peril. This is a very nice build but mechanically I'm not too happy with it: cells can shake loose and short out with neighboring cells, some of the cells don't even have shrink wrap on them and there is enough weight here that it will probably self destruct when dropped. Nice concept but it would need a lot more work before I would consider it safe enough for replication. The hard case itself is not enough protection for a pack like this, you'll need shock absorbing lining, isolation, moisture sealing and so on.
This can be great for camping. :)
Why not one big module? What benefit is there to make 14 cell modules?
And wha is a real usage of it? Why you not using a car/bus acumulator for 1/10 of price?
Sure, its cheaper, but it also has lower capacity and is heavier. Its also bigger
Those are starter batteries, which don't like to be deep cycled. I personally would prefer to use a marine battery, you get more capacity with that.
where did you buy those green wraps from? i know you can buy them from anywhere but those green wraps you have seem to match the right green as sony use and i would like to buy them?
