Thanks for the very informative video it looks like you must have done many of these as you waited till you were finished wrapping everything up before you tested it which indicates a high level of confidence LOL it will be a while before I get there because I still worry a lot about sparking and smoking when I'm making final connections as I've only done it once for a battery backup (for the next hurricane) as basic LED lighting using salvaged 18650s from old laptop batteries and copper wires but I have aspirations for eventually reaching your level of expertise even if my confidence never quite Rivals yours.

Very good effort and work.

When the nickel doesn't lay flat you reduce the contact area...yes the welds create most of the contact area in terms of keeping resistance low but I like to stretch the nickel out and use magnets to hold it down along the way

Great video @2:29 you should be careful laying out your strips like that. If one side is spot welded that could’ve caused a bad short. Regardless great editing.

the BMS capacity always should be more than the total AH of the batteries?

What type of solder welding machine you used...?

Wow very good I like for watching your video 👍

where do you buy your cells from ?

Well done brother 😊😊

18650 are awesome because they are small and you can use a combination to make any size you want. Unfortunately, they are mostly available in NMC format only. The industry should scrap NMC and switch to LFP entirely but some vested interests prevent this from happening.

cleanest mosst proffesional job ever

What is your estimated total investment (of materials) in this build (not including your time) and where did you Source your parts?

Best work,

Excellent make

Assuming those are quality 18650s, that pack should be able to easily do 8000+ watts.

What is the yellow material holding the balance leads and where can I order it?

What do you call the plastics you put? The yellowish ones.

Oh god that’s huge and awesome 👏

Nice. Thanks. Product list.

Sir Can you tell me where you got the cells ?

What's the cost of one particular finished battery after the project completion ???? Kindly reply 🙏 😊...

No hace falta decir que la sección final de los cables principales son extremadamente inferior a la sección necesaria así como la soldadura del negativo ha sido completamente deficiente. luego pasa lo que pasa con este tipo de montajes...

Nice video mama

Good job

With 2000watt motor, ability of these batteries, can reach until how km? And for the max speed until how km/h?

👍

Why would you use nickel to join to the two sections? You could have used copper wire or copper bar stock and soldered it on to the overhanging nickel and had much less resistance for that long jump. I get it, I don't like the folding a layer of 2P nickel and joining the packs in the middle like that but the reason why its done is because when you do the long jump from the bottom of the bottom pack to the top of the top pack thats a considerable distance. If you measure it with an RC3563 you'll see it can be several milliohms which is going to be more than your other series connections possibly (you might have countered that by using several strips of nickel.) But then you spliced those two wires together like that??? My man! Before twisting those wires together you had the perfect opportunity to shove all those small wires into the larger wire and then wrap the solder around the joint really tight. When you solder it it will stay together almost as tight as you had it wrapped. Much better mechanical connection (but nothing beats using a proper crimping tool and using a solid copper butt connector)

hi sir 21700 lfp cells will be there

Please make video to use electric bike removable battery of 72volt for charging laptops and mobiles at home.

Aap 72v ki battery bana sakte hai to kitni cost ayega Total

Battery kya price ka hai sir ji

👌🥰

will 2600mah cells work?

how much for a battery like that with anderson plug

呢個電池大約需要幾多錢

4:00 side me jo yello colour ka plate dale hain ...usko kya bolte hain name batayiye

what merk and specification of battery ?

How many cells needed if I want to make 12V 100Ah?

How many hours irl ?

What about weight?

Can you make 36v 15ah bicycle battery pack with halong case

Mera ek bhi ban jaay ga Kitana price lagega

How to charge it bro

Where did you buy the H nickel strips from?

how do you charge this?

Sir iska size Key rahe ga

Can you make a battery for my bike, 60v and 20Ah. for me. and I will play for it

I would have the temp setting at 75c & cook that battery in 20mins. wrapped too much . All the heat stays inside. keep the ends open & send air through it while charging or just waiting for the next race.

Finally battery sizes

Battery kaha pe milegi

72v 35ah bayatri ka mrp kya hoga

Raw materials kaise banega

You don't gave us purchasing link,s

Quiero una así para mi moto

Gjb battery pack banaye hai bhai..

Can I get this made from you for myself? If yes then how much would it cost me?

Bos mau tanya batrai sy cepat habis di cas cepat penuh padahal sy beli baru bos minta solusinya bos

Where did you get the batteries?

What is the price of battery 🔋 price one battery. And where we can find. That battery

Am wondering why the use of tape is used so much for holding things when it's just going to be shrink rapped anyways

Kitna rupees me ye battery ban jaye ge

Quiero una me puedes fabricar una yo te la compro 👍 dime cuándo dinero me puede costar gracias

Good work bahi

Looks like a nice work, but some design choices that don’t make sense. That strip looks too thin, doesn’t seems pure nickel, just cheap nickel plated steel, not good for such high amp battery, too much resistance it will heat up a lot, a lot of sag and voltage drop. That “bridge “ between the two parts is ridiculously long, it just creates too much resistance between those paralel groups, it’s not even recommended for the BMS to have those differences in the contacts lengths to make an accurate voltage reading and balancing. Like I said just look good, bad, inefficient and possible dangerous design.
