How to Make the Ultimate 18650 Power Bank with Infinitely Expandable Capacity
ฝัง
- เผยแพร่เมื่อ 1 พ.ค. 2024
- In this video I will show you the ultimate solution to power on the go. This DIY power bank features a removable battery pack, which can be easily replaced, giving this power bank unlimited capacity as long as you have enough cells. The cost of the row components of this power bank is around 60 dollars, which is two times cheaper than anything commercially equivalent.
WARNING: Do everything at your own risk, lithium batteries can catch fire or explode if mishandled. This power bank requires a more than a basic understanding of electronic to complete.

Lot of people posting their projects on TH-cam but they don't public thier CAD files. If does, they required for money. You did a huge project which I can't imagine to do myself. And also you have publicate to others who like me to encourage. I cannot imagine during this project how much of time, money & failures you have faced. That was made me to thumbs up & subscribe your channel. You may have all our blessings to do more and more. Thank you so much.

John Chrysostom when doing big projects like these, there is bound to be roadblocks or something not going just right. There is no getting around it, no matter how good at electronics you are. If he managed to do this whole thing with nothing left to truoubleshoot, I would be beyond amazed.
@John Chrysostom Every innovation projects are facing for bugs & issues. But with the patients, corrections some of them are achieving the goals successfully. Thats what I wanted to tell him & how thankful I am for this.
It is not a power bank, it is a power station ... You are a genius
@@elixier33 have you tried it
Goal Zero calls this type of thing, a Generator, because this turns battery output, to AC line voltage, to normal Outlets. I have a "Yeti 400". It is a battery/powerbank/inverter, and this charges up via outlet, or solar panels, by Goal Zero.
A power station generates electricity. This doesnt.
@@TigerManGaming i think he meant station as in a larger capacity system. You are right though, power stations are technical names for transformer stations and generator stations
Just wanted to say thank you. Really appreciate the work you've put into this, and I can't wait to build it.
Did you make it?
Holy crap dude! That's just a work of art. If you came knocking on my door for a job and I had seen this video then I'd hire you on the spot, no questions asked.
you know he's a engineer and not executive when he's put more protections on it than they are willing to pay for and it's got more functions than beautifications
exacly what I need. I dont need cosmetics. I need raw performance. Sell me one? ;-;
Kickstart it? It could be really really really awesome kickstarter campign....
It's not ugly though lol
@@BlowitAllUp It's not beautiful, it's ASTRONOMICALLY BEAUTIFUL
You should honestly see his first version. This is like 10 000x times better :D
@hXcFreethinker nice to know, I hope he makes a version that does not require soldering the batteries
dude you should make this a kickstarter, id back it for sure!
Edit: not gunna say thanks or none of that mumbo jumbo but i will say im surprised to see how many others simply cant be arsed lol
saaame
was thinking the exact same thing when i saw this.
I'm in.. +1
@@NightForce hell yes
Lets make this guy have a happy retirement
That battery pack is amazing, so clean and simple. lovely design
Those tolerances are amazing. love the cad and design work too
I have completed this project and its great. Here are some corrections for anyone interested in building this.
3:11 It lists 2 Mini DC step down converters when most likely, only 1 will be needed. The second is use to lower the speed of a fan if it is too loud.
3:45 make sure that you buy the correct size switch as shown here. I purchased ones that were 1/4 of the size and had to 3D print custom enclosures to make them the proper size.
4:00 The copper strips are not needed if you spot weld the batteries. The zinc strips worked well. My power inverter also already came with heatsinks.
4:21 he says 4 NC and 3 NO 45°C bimetal thermostats when it is actually 3 NC and 4 NO needed.
9:18 if you are using a flexible filament for the outer bumpers, there is a remixed STL file for the ring to be printed in flexible filament. That hinge is impossible to locate.
11:07 the hole for the USB C trigger is very large. I used tissue paper with glue to fill the hole. Hot Glue may also work. You can also shrink it in the files that is provided.
13:49 The graphic is incorrect but the video shows the correct pin, the wire goes to the common terminal of the relay which is why he offset it to do so.
14:08 The second pin of the switch gets used later, it goes to the relay pin shown in 19:24
14:39 Be aware how you solder the wires to the potentiometer as a voltage gauge is mounted directly above it as seen in 15:45. 90° solder joints are what I had to use.
15:24 The other wire of the switch goes to ground
21:53 This isn't a correction but you can drill a hole or bore one with a soldering iron in the center of the charging coils to run one of the connectors below the board. I don't know if it helps but I copied it like seen here.
Most useful commentary
I've completed it and posted some pictures of it in the made section in the thingiverse link provided in the summary.
th-cam.com/video/pKnB_AYzoJQ/w-d-xo.html
Many of the parts and components used were different than the recommended components. This was mostly due to error but I had to make them work. Unfortunately, this meant that I had to redesign many of the existing files. Thankfully all the cad files were provided and easily modified with Fusion 360.
I got a 10 watt fast wireless charger instead of the recommended 5 watt. This will charge wireless devices twice as fast but it was larger than the recommended. The charger actually needs 9 volts instead of 5 volts to use it's full potential. I used a mini step down converter (purchased 10 by mistake) to drop the voltage from the battery down to 9 volts and soldered the power cables to the wireless charger. This way, I don't need to turn on the usb charger switch to turn on the wireless charger. I also got RGBW (additional White Light) instead of RGB and the controller was larger. These upgrades required the top compartment, and outer shell to require modification. The inset for the wireless charger circuitry had to be pushed more toward the center of the device and some of the dividers needed to be removed in the top compartment cover. The outer shell was changed too. I pushed the target circle for the charging back to it's new location, holes were relocated to match the new outputs of the lights and RGBW controller hole was changed to be more clean. I made a new switch cover and completely closed the hole that is usually on the top.
I had to modify the IO plate a decent amount. All the text had to be enlarged and they had to be put in a bit deeper. I also had to enlarge the hole and add some cutouts for my outlet plug as my plug had side tabs, which meant that I needed no glue. I also had to lower the LED hole for the inverter my 4 mm. I literally printed about 11 or so IO face plates till it got it correct. The usb 3.0 charger I got was much smaller than the one recommended so I made a adaptor tray with a thermostat slot for the new circuitry to sit on. The CC/CV buck converter was also different and had no screw holes so I used some high power 3M double sticky tape to hold it down.
I had a spot welder so no copper strips were needed. I had some nickel strips which I used. Fortunately my inverter already had heatsinks.
I used some pretty good cells that tested out to be great on my iCharger 1010b+. On my first test, the capacity came out to be 17,226 mAh @ 11.1 Volts or 191.2086 Watt hours. Does it seem low? 191.21 Watt hours is about 52,000 mAh at 3.7 volts if I were to show the capacity like most scumbag sellers do.
Only thing left is to properly print the badge.
He said 20 amp fuse but the screen said five amp fuse
@@PlateInStock He said 20 amp, the schematic says 20 amp and he used a yellow fuse which is 20 amp. Use a 20 A fuse.
as a noob and only knows how to solder and has a 3d printer, it would be nice if you make a separate video tutorial step by step guide on how to assemble this. i can only copy cat/ monkey see monkey doo things honestly

Dude you are a boss. I can't thank you enough for making all of this free to use. That isn't very common these days. I will make a reply video for you using your knowledge and show you what I built from it. You're awesome
We need more people like you in the world! Thanks for sharing such great details.
my brain : yes! I can make one!
my hands : no! you can't!
I feel the same exact way lol
@@thomastownsend8510 I feel the same ja ja ja ja ja :) :) :)
feel like I could make one if I want the biggest problem is the getting my hands on a good 3d printer
@@twisteddarkdays8150 I wanna a make one too but who said you need a 3d printer just make it from plastic sheets and hot glue lol
i could make it, but i feel like its gonna blow up if i did
I didnot know why i watched it for 24 minutes without skipping?😂😂. i truly liked it. Thumbs up. 👍
Im wondering now wht i watched
Hahahaha hasaucha solti ley. Same here bro.
same lol

@@goldcd Indeed, its' unreal reality!!! )
This was hands down a great video! I am trying to get into electronics and dont know much but i think this was very informative. Thanks for sharing!!!
That's the coolest project I have ever seen. just cheaper than commercial power banks with more capacity but DIY is a way to make our own idea for cheaper and also with the ideas you have. that's great
This is the manliest battery pack I've ever seen, love it.
I wanna order it
He missed the fact that 18650s are bad for sparking or exploding it's what people use in vapes and when it was wired wrong it blew up part of there face. I wouldn't recommend using an old one by any means
@@Im_the_Trashman_ god.. That's scary
@@Im_the_Trashman_ name brand 18650s are perfectly safe if you don't short circuit them and don't exceed their discharge current. They are certainly safer than the Li-ion batteries inside your mobile devices.
nah... it has rgb.
Hello everyone, this project sure took me a long time to complete...I hope you enjoyed it!
Additional schematics and the full script are in the description. If you have any questions regarding the build process or design choices, please ask them in the description. I will try my best to answer them.
Hey bro are you interested to sale it
Sell the Power Bank itself!
friend, you are amazing!
100% Copy will be sold in China in like 4 Weeks! no BS..
Better get a WW Design-patent ASAP! just sayin..
Instructions are through, just love it,
He is not saying i can do it,
HE IS TELLING US LETS DO IT
Holly those complex circuits blows my mind. Awesome video mate!
So, how many features do you want in this powerbank?
This guy: Yes!
Thanks for giving out more information then the $60,000 mah
That was awesome, it's unbelievable how you think each part perfectly.
Do impressive! Thank you for taking the time to share your great genius!
I just want to recognize the integration work you did here. You made use of inexpensive components and techniques to great effect. I tend to overbuild and I respect your efficient and minimal approach here, while still showing abundant consideration toward thermal stability and so on. One of the best DIY videos I've seen. Good job!
Hello Friend!
th-cam.com/video/RSJZJXzgZQo/w-d-xo.html
Not very often do these DIY projects actually take into consideration the level of safety and understanding this guy has
Wow the incredible amount of thought put into the details of this is insane. Without putting together a pcb design you somehow managed to make one of the most feature packed, high capacity, portably small battery pack I've ever seen.
There are no words to describe how impressive this is.
Impressive! I decided to make a portable station using 18660 batteries and this was what I needed for tips
This is one of the best projects I have ever seen.
The best video project I've seen,
all due respect ! You're on a high level
That was a well put-together video. It was structured, very detailed and the layout of information was easy to absorb. I would come to this channel often if you could make easier stuff lol. Less intricate electronics diy lessons so you have more time to create more videos. Thanks for your hard work!
This was incredibly done. Thanks!
thank you for sharing your creativity, experience, and time.
This is the world's best power bank , thank you for sharing your knowledge with us.well done keep up the good work....
Started 3d printing all the list thanks for the help
Dude, that was awesome I'm well impressed with your job!
This is easily one of the best DIY tutorials I've ever seen on TH-cam, mad props to you! It's not only a unique and impressive project, but you do a really great job of walking through the steps and making sure it's detailed but not tedious. You are a very good communicator! I didn't plan on watching the whole thing, but only a minute or 2 in it really grabbed hold of me and it was over before I knew it! (Btw, I think you pronounced removable perfectly well!)
God bless :)

Especially
Absolutely, a great project. Thanks for sharing
Applause for a great example of electronics craftsmanship ! ❤
This is super incredible! I love your design and I think it's very clever, I'd love to try and make one of these one day. Awesome job
Really great project!
Everything all in one, LEDs were a good addition too.
я бы еще подсветку настроил в тон индикации зарядной платы
Learned a lot! Amazing. Thanks for sharing this. :)
Awesome video, I like DIY videos but never before have I seen any such video in the style of this one, I haven't built this nor will I build it(I will build some smaller battery bank though) but I really enjoyed the whole video. Great work!
I start the video like, 'oh another 18650 battery build. I hope no one gets hurt trying to build these without knowing how to properly discharge and I hope heat isn't a problem'. 15 min in, I am convinced you are a wizard! Way to pat attention to safety and thank you for your detailed instructions!! This was a great video!
love the video and been wanting to build one like this for a while now, even have the 18650's, but I'm new to building electronics so want to start small and build my way up, so gonna build the hand warmer you made when I get some time. I'd love to see more videos like that, small projects that are fairly easy to do and follow, that way I can get experience to build this baby. Great videos and great channel keep up the good work
m nt gonna say your project is brilliant m gonna say ur the brilliant guy and realy kind person .. no one share there CAD files but u did thts very appreciate
Good day sir
Love your videos, though complex but I discovered that by playing it countless of times help understand your connections well an wised to be guided to build like you.
Good work sir
deff the most advanced manufacturing techniques and array of diff techs combined of any diy 18650 video ive ever watched. very amazing great work! ty!
A real pleasure; Thank you so much !
Congratulations, you are among the best
Dude I love this thank you I've been searching for one of these online now I'm just gonna build one
Absolutely brilliant. Thank you so much.
The algorithm has blessed this video. Subscribed :D
Beautifully done.
Even though I would never attempt the project, I do appreciate the CAD plans being made public.
I would consider purchasing a finished version though.
Good job! Appreciated your design!
This is mind blowing DIY i have ever seen. Unbelievable Job. Thanks Alot..
Lol the more I watch, the more I am utterly impressed. You are a genius
I wish I could give an internet standing ovation. that was amazing.
wow you did really an great job on this, i like it
This is a dammed good job, wow, there are so many features. It's amazing!
Best portable power pack i've ever seen
Awesome work
Instantly subscribed when you show the BOM list. Very detail project, keep it up bro
This is actually amazing
My interest is DEF peaked. Thanks for sharing .
I'm conjuring up a design similar to this that I can plug into a portable solar panel. Thanks for the motivation 💪
Dude that really awesome
I wish that u make more DIY projects like this
This is what I've been looking for for months! You are a god! Thank you!!!
I like this version a lot better than your newer one, it's a lot more practical for me. I also have a lot of used 12v 8 amp batteries that are form alarm systems that where replaced because they can't have a battery fail in an power outage so they get replaced every few years, so these batteries never saw a lot of discharge and recharge in their operation, so they work very well, it would be cool to see you come up with something similar for these types of batteries.
That's incredible!! Well done!!
I used to feel like Iron Man, by just connecting a Dc motor to a battery.
The project is God Level (at least for me)
You blew ma mind, keep it up.
Behave he brought it all of eBay 😂😂
Why am I watching this? I can barely put together legos
ive worked on electronic project since i was kid and this looks hard AF!
how you understood this if you didn't try? do you think other people was born with this knowledge and skills?
Me too
because your brain is telling you. TRY IT :D
Me too! You lost me at hello! LOL!!
excellent project, congratulations. I watched with admiration from start to finish.
That's a hell of a project i am definitely doing it
Let me know how it goes. I’m hoping to build this one day. I’m gon a build the lab bench supply first.
This was a very well thought out project, im glad i found your channel! Liked and subbed :)
Just GREAT!
I agree with the others - you should make this a kickstarter. It's a great work.
very well made, with so many details, wow
All the best for your super projects - the one with the power bank and the portable 3D printer. I really like the way you set up your solidworks interface. I really like this, maybe you can do a tutorial for those who like this interface at Solidworks but haven't dug so much into these settings. Special respect man. ❤👍😍
This video is very well explained! Thanks for that!
Bro you are an amazing genius. Keep sharing good video like this.
Absolutely incredible! Cheers!
An amazing project with an extraordinary video! Excellent!!!
It's awesome man I always wanted to make this kind a powerful battery pack now this video will help
Thank you for having confidence in us to build it.
none of the actual build is hard ... finicky sure but not hard ... mind you the adjustable soldering iron he has is not something most people have
it's just perfect.
good job
Wow, this thing is incredible. I would love to build it... but it's a little beyond my skill. Maybe some day. If/when I'm ready to try it though, this video does a great job of walking you through it. If I had a more urgent need for this thing, I would definitely make it.
You are really some next level thinker and builder; fantastic job on this.
What a satisfying video it was, MAN!
I subscribed you 🥰
👍👍Amazing project. Well designed, well explained. Thank you for sharing and thank you for motivating beginners such as myself by sharing your learning path and acknowledging your design and circuitry limitation. I am looking forward to reproducing same or similar project.
Absolutely amazing advice
I get a DIY Perks vibe from this video. Awesome build mate!
Now that is the power bank that ive been looking for
Nice idea, something I would implement in my DIY battery pack for the phones and possibly laptop - with some changes, I would have to also install smart battery pack board for the removable battery so it keeps all of the information regarding the state of charge and aging data thereon so runtime remain accurate.
Superb...Looks amazing and so useful. Thanks for sharing.
Absoluty amazing project. Thank you for sharing everything. Amazing Video.
Neat and amazing work! This could well be a good kickstarter project!
WOW AWESOME VIDEO. ON TOP THE NEXT ONE.
THANK YOU I REALLY APPRECIATE THE VIDEO!!!
