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.

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

where do you buy your cells from ?

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

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

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.

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...

cleanest mosst proffesional job ever

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.

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

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

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)

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

Well done brother 😊😊

what controlller should you use??

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

Wow very good I like for watching your video 👍

Very good effort and work.

Oh god that’s huge and awesome 👏

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

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

Where did you buy the H nickel strips from?

will 2600mah cells work?

hi, how do you charge this battery?

Nice. Thanks. Product list.

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

Sir Can you tell me where you got the cells ?

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

Excellent make

Best work,

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

how do you charge this?

Whats the voltage of the cells

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.

Good job

Lithium ion battery pack kitne rupees me milta hai

You don't gave us purchasing link,s

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

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.

How many hours irl ?

এটা চার্জ হতে কতো সময় লাগে

What about weight?
