Excellent work and thank you for showing how to set up the BMS
Your handiwork has made a very beautiful battery pack.
Excellent technique, very well done
Amazing dexterity!
Excellent job mate. Inspired
Eres muy limpio trabajando, sí señor 👍
That's not a battery. That's a work of art!
Thanks man 👉
Nice build, very clean
Good job - looks factory made . Impressive. That spot welder works great. I want to do same to drive my 24V garage door opener motor.
He made a 240watt battery pack cool
Nicely done! I’ll follow this to make mine and thanks.
Could you put a component list what was used and where to get ???
Very professional !
I liked your cable management 😉
What kind of Spot Welder did you used to do that battery?
Nice neat work
Nice work👍👍👍🙂🤝🤝🤝
Thank you for your video clip! :)
Nice job!
Excellent art of batteries! I'm newbie on this, may I get your recommended tools name & brand? Thank you.
Super video merci
Le décapant en burette la marque
This is just a seven cell, 24v battery, butt three wide, yeah?
Off of the same bms.
I was unaware you could do that.
Excellent.
I need some fat-assed batteries for the boy's electric scooter.
Thank you random stranger!
Holla budy can you please tell us what kind of Spot Welder you were using in this project please?
beautiful work dear
Hello,
May I ask which cable cross-section?
you used ?
Thanks in advance.
Pls can you tell me the tools used to make the battery.
Thank you
Very professional work
Why is it that after you finish assembling the battery there is no trial?
hi what bms was used for this having trouble finding one ?
Good job pero donde pudo conseguir todo lo que utilizó en este proyecto especial mente las baterías 🔋 y el bms
Sir your all components name please mention in tutorials video & also battery soldering machine name mention many many thanks you.
Love your technic
Nice work! How did you make label or what kind of label printer did you use?
sorry but can't you explain what those black battery holders and the various stickers you stuck are? And then there would also be that circuit board you plugged in later. Can you put the links where you found the various materials and tools you used to assemble the battery pack? Thank you
Thank you
How much does it cost for a setup like this?
Brother you made a nice video. There is no background music so i clearly vision and understand what you have done..
Thanks 🙂
Pls make a video about diy spot welder
Next time :)
Where did you get the BMS
Pekna praca 👍
Vďaka :)
Was kostet solch ein fertiger Akkupack?
Di solito nn vanno saldati prima i paralleli?
Can i build the same configuration (3x7) but having only 20 cells ?
Hola muy buen video pero la duda que tengo es porque lo de los 2 terminales gracias
Where did you get the wire stripper?
My only suggestion will be to add the gasket insulator same you use on the side of the battery on the top and bottom or fiber glass insulators. Other than that looks amazing.
Thanks for comment. Yep, today we use fishpaper for all sides, battery pack is wraped to shrinkable foil like in video but on sides we use insulator glue for waterproof efect.
Really professional
Nice Sir
Will it matter if I get a 15amp bms for this battery pack?
Thank you 👍👍👍🍮
Very nice video. The only thing that I can't figure these joints. And you can make mistake only once :)
How much would a battery like this cost to buy
Thanks for sharing.
can you send me the schematic diagram of the connection of wire from the batteries to BMS and charger ? Im going to build a batter pack for my electric bike? please reply immediately thanks
24v 250w electric cycle range kya hogi battery se?
24v 250w e cycle kitne km chalega isse?
I have created a 7s 15 p battery pack with bms, and tried to use it with apc ups.. It just trips when power goes.. When i use it with existing battery in parallel it works fine
Hi, voltage is same? 7S has 29.4Vmax, try discharge battery to 24V and try use it in ups.
Check bms limits
very nice videoplease,where i find the nickel stip
can you make a battery for dell Inspiron 9300 with max watt hours
and 11.1v
Ciao mi sono iscritto da poco lavori molto bene bravo! hai realizzato un pacco batteria per tassellatore Hilti 36v hai un video?
Great job. Worked systematically.
They say if you cut the balance leads unevenly short and long, there will be difference in resistance and the cells will be charged unevenly. Is it valid?
Its a small pack its ain't gonna get a potential difference between the balance leads
3kw ziewnic inverter?
awsome work. what spot welder do you use to weld the battery strips together (5:33)?
Sounds like a Sunko
Good job..very beautiful..can you detail you materials use ang where you order..thank salute
good work
Hallo 12v 18 21 ah ungefähr wie viel kostet?
Hi Thanks for the video very helpful. My first attempt at making battery pack for EBike, only able to get 18650 2200MAH cells, will they be ok to use?
I think yes, but what about specs of cells?
@@mcells_batteries how to calculate 2200mah cell 10 Ah ?
What is the diameter of the hot shrink pvc?
nice work
lavoro profezionale
How much is this battery?🙂
Great video, that very first weld on your first spot didnt look like that first weld took, i only see one dimple on your closeup, rest look fine.
Yes, sometimes is welding pressure little bit different and it make some changes but it has not effect for final work.
Nice work bro.. i want to build 60v 24 ah battery pack for my electric bike. Can you please send me diagram.

Hey there! I just want to make sure, you designed the battery as it has different discharge and charge cables, right?
Hi, yes.
@@mcells_batteries Alright, can I use the same port to charge and discharge? Would it cause any problem in the future? The BMS that I am going to use supports this feature.
@@bars3402 there is common port, and different port.. 2 different bms
Hi where your location please?
Very very nice pack and craftsmanship but the sound of your tools smashing the table was Killing me....
Get lower volume :D
Hi! the video is superb. I would like to ask you why you use a 7s configuration instead of 6s? which do you recommend and why?
Hi, thanks :D 7s was better for customer device, has higher voltage, higher energy instead of 6s.
@@mcells_batteries thanks for the fast replay. If my device has a nominal voltage of 24V VDC, would a 7S configuration be suitable or 6S is more recommended?
@@m.barrios You need know maximum possible voltage, but if is 24VDC nominal voltage i think you can use 7s.
@@mcells_batteries thanks so much for you support! Continue the good work 😃
What is the name of battery cover tap
What is the total weight of the battery you made?
And can we use them for radio controlled vehicles?
Hi, weight of this pack was 1300g.
Probably yes, but it depends on many parameters.
Gostei muito
nice
Question for you... I need a 4.8v - rechargeable pack for my filter system on my welding helmet. Battery system on filter isn't giving the working time I need. Any idea if this is possible with as high as 10AH and compact enough that it can hang on a belt? Appreciate any help with this...
Está bien la armada pero tiene que poner un diagrama de posición 😅
Hi, can anyone tell me what is the white striped wtape tht was used to hold down the BMS called? Thanks in advance! Appreciate it.
It’s a certain kind of packaging tape that has “strands” in it to give more rigidity. For the life of me I can’t remember the name.
What's was that you put middle of the batteries the black wire ?
Temp sensor
Brother Nice demonstration and excellent clean work. I just have one doubt.. why did you use a black wire for battery and charge positive ? and why a blue wire for battery negative ?
That's when I ran out of wires :D
This is awesome! Anyone else getting OCD about the label alignment?
Lokks amazing
👌 perfect
Sir muje e bike ke liye 48 v 50 hr ki battery chahiye uski price kitni hogi Rajkot gujrat me chahiye
Nice build, very clean, thumbs up!
But 2 comments from my side:
-At 5:10:
Too dangerous in my opinion: While welding on the second side of the battery, there should be some tape for isolation on every cell you are not working on at that specific moment. If you missplace your strips left or right or one strip falls down on the pack while handling it or something like that you´ll get a short. Also if there is a metal strip or anything else conductive left getting under the pack.
-Why are you using black for the positive discharge wire???
Hi, thanks 🙂
1. - Yes, I realize it but I know what I'm doing. Therefore, I often check the location of the connectors.
2. - I ran out of red wires 😁😁
Ran out red wire lol
That lap solder joint will reflow under high loads and let go, in my experience. I encourage you to consider a linesman splice or similar mechanical joint under solder.

It's using 7S BMS
What would be a 7s to ?P for a 24v 22ah -/+ battery pack
Hi, maybe 6 or 7P. When use 3500mAh cells with 6P it will be 21Ah. When use 3200mAh and 7P it will be something about 22Ah.
Are those dark green insulating rings necessary?
Hi, yes. These insulating rings are used to strip the cell and the connecting pad.
I think the battery casing is metal.
No, even big company like bosch doesn't use it, because the cell already has one isolator ring. But extra is better.
Quanto mi costa fare una batteria così da 24 v ma fatta da te io penso di non essere in grado di farla
How can I assemble batteries with a capacity of 24 and a current of 150
Capacity of 24Ah? You’ll need a (insert number for voltage) S and 10P pack if using 2400mAh cells. (Insert)S5P if using 4800mAh 21700 cells. 3000mAh cells would be (insert)S8P.
The first number I’m omitting is the cells in series. 7S for a high 24V. 6S for a very low 24V. 4S for a 12-16.8V and 3S for 9-12.6V. Thankfully 36V fits just about perfectly at 10S with 3.6 nominal and is close enough for 3.7 nominal cells.

How's the temp.cut off with the red cells?
Inside of pack is bimetal switch with cut off temp. 70°C. This protect pack from high temp.
10Ah 🤔 what type of 18650 did you used?
Hi, was used Sanyo GA.
@@mcells_batteries nice 3500 for 10 cd nice video hop you can make one about 21700 5000 with a holder 8 slots double sided 🤞
A physical barrier more than kapton tape would be preferred for the BMS/balance cables. Something like barley paper but this is a really minor thing to point out. The fact that you're using kapton paper is enough honestly, TH-cam is full of Indian kids using cells that look like they died 10 years ago and have been rusting away at the bottom of a river ever since, put together with zero capacity, IR testing, no balancing is done prior to assembly they don't even look at cell voltages and then they solder some random wire to the terminals and call it a day. Followed by 1200 comments saying "Genius boss you are great. I wish one day to build battery like you"
Ehhh 20 seconds later the barley paper comes out!
This is a quality build, just don't use the Smart Daly BMS's. The dumb ones are just fine though, good price and they work.
Hi, thanks for your comment :D
This build was build 2 years ago, so today we use fishpaper for basic insulation between cells and balance wires.
We learn from other and sure from our mistakes and aplicate it in next builds.
Today we build our own busbars, our holders, 3D projects etc. but it was long way and i think that it will be much longer :)
Next year we will start produce more videos and you can see our progress.
Mi puoi mandare il link del carica batterie grazie e anche bms
