Excellent work and thank you for showing how to set up the BMS

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!

Your handiwork has made a very beautiful battery pack.

That's not a battery. That's a work of art!

Good job - looks factory made . Impressive. That spot welder works great. I want to do same to drive my 24V garage door opener motor.

Eres muy limpio trabajando, sí señor 👍

Excellent job mate. Inspired

Excellent technique, very well done

Sir your all components name please mention in tutorials video & also battery soldering machine name mention many many thanks you.

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.

Could you put a component list what was used and where to get ???

Amazing dexterity!

I liked your cable management 😉

What kind of Spot Welder did you used to do that battery?

Nicely done! I’ll follow this to make mine and thanks.

Nice build, very clean

Thank you for your video clip! :)

hi what bms was used for this having trouble finding one ?

Excellent art of batteries! I'm newbie on this, may I get your recommended tools name & brand? Thank you.

Hello, May I ask which cable cross-section? you used ? Thanks in advance.

beautiful work dear

Pls can you tell me the tools used to make the battery. Thank you

Brother you made a nice video. There is no background music so i clearly vision and understand what you have done..

Where did you get the wire stripper?

Why is it that after you finish assembling the battery there is no trial?

Very nice video. The only thing that I can't figure these joints. And you can make mistake only once :)

Very very nice pack and craftsmanship but the sound of your tools smashing the table was Killing me....

Holla budy can you please tell us what kind of Spot Welder you were using in this project please?

Super video merci Le décapant en burette la marque

Nice neat work

Good job pero donde pudo conseguir todo lo que utilizó en este proyecto especial mente las baterías 🔋 y el bms

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

Nice work! How did you make label or what kind of label printer did you use?

Very professional work

Will it matter if I get a 15amp bms for this battery pack?

Nice job!

How much does it cost for a setup like this?

Very professional !

very nice videoplease,where i find the nickel stip

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, KZfaq 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.

Can i build the same configuration (3x7) but having only 20 cells ?

Was kostet solch ein fertiger Akkupack?

How much would a battery like this cost to buy

Hola muy buen video pero la duda que tengo es porque lo de los 2 terminales gracias

Good job..very beautiful..can you detail you materials use ang where you order..thank salute

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.

Love your technic

Di solito nn vanno saldati prima i paralleli?

Nice work👍👍👍🙂🤝🤝🤝

24v 250w electric cycle range kya hogi battery se?

Thank you

injineer you have done will we love you.

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

What is the diameter of the hot shrink pvc?

Thanks for sharing.

24v 250w e cycle kitne km chalega isse?

Hi where your location please?

Really professional

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?

Hallo 12v 18 21 ah ungefähr wie viel kostet?

How much is this battery?🙂

Nice work bro.. i want to build 60v 24 ah battery pack for my electric bike. Can you please send me diagram.

awsome work. what spot welder do you use to weld the battery strips together (5:33)?

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

nice work

Thank you 👍👍👍🍮

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?

Pekna praca 👍

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, can anyone tell me what is the white striped wtape tht was used to hold down the BMS called? Thanks in advance! Appreciate it.

What's was that you put middle of the batteries the black wire ?

Next time, build a rig for the soldering job. holding the T-Connectors is better as soldering them on the table - thats not a good solder job here. dont do this like shown here ^^

Ciao mi sono iscritto da poco lavori molto bene bravo! hai realizzato un pacco batteria per tassellatore Hilti 36v hai un video?

What is the total weight of the battery you made? And can we use them for radio controlled vehicles?

3kw ziewnic inverter?

can you make a battery for dell Inspiron 9300 with max watt hours and 11.1v

What is the name of battery cover tap

Hey there! I just want to make sure, you designed the battery as it has different discharge and charge cables, right?

good work

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...

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.

Bataryanın eni boyu nedir boyle bir batarya 12 volt 9 amper aku kutusuna sıgdırmak istiyorum

This is awesome! Anyone else getting OCD about the label alignment?

Lokks amazing

Sir muje e bike ke liye 48 v 50 hr ki battery chahiye uski price kitni hogi Rajkot gujrat me chahiye

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?

Nice Sir

Are those dark green insulating rings necessary?

lavoro profezionale

How's the temp.cut off with the red cells?

Quanto mi costa fare una batteria così da 24 v ma fatta da te io penso di non essere in grado di farla

What would be a 7s to ?P for a 24v 22ah -/+ battery pack

Silent movies are the best....

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 ?

Hello, I assembled the same battery, tell me to charge it only at least 5A charging?

Está bien la armada pero tiene que poner un diagrama de posición 😅

How can I assemble batteries with a capacity of 24 and a current of 150

looks very commercial. two tips. bigger heat gun. dont cross bms sensor wires. if they short to each other or get pinched = fire

10Ah 🤔 what type of 18650 did you used?

👌 perfect
