DIY 72v 35Ah Battery Pack For 2000W Electric Bike

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.

कृपया एक इके से संलग्न करें और बहुत लंबा विवरण दें। डिटांस, शीर्ष गति। धन्यवाद।

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

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

what merk and specification of battery ?

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

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.

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

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)

Sir Can you tell me where you got the cells ?

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...

Battery kya price ka hai sir ji

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

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

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.

I can you make me one and how much please

Sir iska size Key rahe ga

OK, I don’t get it, why do I care to know how you build them,? I wanna know where to buy it and how much is it?

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

Pls what is the calculation for 60v 20ah

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

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