Wow, really appreciate the close up assembly and even without words, I learned to assemble a battery pack.

[@TheLondonCyclist]

I really enjoyed this. I watched the whole thing. I love the way you have it close up while you're working, it helps me learn exactly what and why you're doing the things you're doing. I couldn't get this info from other videos, but your silent approach and close ups help explain a lot.

[@tommuhlemanjr.3871]

That was a really nice build with excellent documentation of the process. Great job!

[@gordonvincent8856]

[@e-bikerbulgaria]

Awesome video. The alternating colours on the balance leads I haven’t seen until now.

[@ronaldmagat6424]

How much is the cost to assemble that?

[@badhonebrahim7707]

Love the slow detailed process without any talk , at least I've shown how to do it step by step, not a jump cut video thanks

Very professional. Nice spot welding pen. Best battery build I've seen yet on KZbin

[@raimundoduarte9188]

Very good indeed! Despite the absence of audio or descriptive subtitles, it was possible to understand exactly how it was done and a great level of finishing of the work itself! Perfect, congratulations!

[@prajullas]

That was one awesome and satisfying video,

[@norbinpazhampilly1075]

I really appreciate your dedication to do it with patience

[@suncity1702]

Good job bro, even the BMS wires colours u used makes everything understandable thanks

[@scootersdenver]

Nice video and y9ou do nice work on your packs! Thanks for the video.

[@squidlings]

I prefer individual cell fuses incase of a bad cell. Tidy job, impressed.

[@TheLondonCyclist]

How do you go about individual cell wiring? Is there a video as good as this documenting it? Thank you.

[@absalonamil7953]

this is an awesome video i learn a lot on how to weld and the connection of the battery awesome job.

Você não fala nada mas seus vídeos são os melhores da internet, não vi nenhum semelhante. Parabéns, yosun!

[@joserolandsancheromero4440]

El video está DEMASIADO BUENO!!! 👏👏👏🤯

[@sreekumarUSA]

Master Yousun, that was a marvelous assembly. Appreciate your meticulous attention to each section and clean set up. A brief description on the BMS type and model and charging voltage would enhance the whole video much better. Last but not least...... please describe your SPOT WELDER. Show us, in sequence, how you made it, what parts were used and the technical data. Thanks again.

[@yousun2827]

I will explain later.

Thank you for the video!! Such attention to detail and great care creating the battery pack. Not sloppily put together.

[@fernandocesar3332]

Perfect this montage the video is very datica. I believe it was the most esplicative I found in yuotabe. I'm wanting to ride a 22S P12 84V 30AH and I was missing this video. thank you

Thanks!

[@vlogerkdeewane2830]

Macho, te ha quedado de lujo el paquete o pack de baterías. Ahora te queda mostrarnos como lo acoplas a la bicicleta y test de velocidad y autonomía entre otras. Gran trabajo realizado y muy curioso por tu parte.

Excelente video no nesecita palabras

[@WsomNatalRN]

Muito bom seu trabalho, bem organizado, essa de 48v 20 amperes

[@usertogo]

copper has one third of the resistance than nickel and can be found everywhere for cheap- I would solder at least the parallelization wires using solid copper wire. Then I cover all my contacts with transparent neutral silicone to decrease the risk of accidentally shortening or effects of moisture...

[@TheLondonCyclist]

I there some sort of spray silicone you can spray over your work after you finish you give it a moisture resistant surface?

[@ecbmanikandan]

[@ehvlullo]

Looks nice, but is that BMS going to balance? Looks like this one (like most) only starts balancing around 4.2 volts per cell. I think it is good to charge cells to only 4.1V for better lifetime, but now I think the pack might not get balanced properly?

[@yousun2827]

When the internal resistance of the connection between the batteries is low, the battery pack voltage will be very balanced. I will take apart the measured voltage after one year.

[@user-ww7lb5ij2i]

good job. Once discharged how will you load it?

Battery compartment on bicycle

[@TM-we6eg]

Is it advisable to put the bms on the outside so you can easily replace it if it fails?

[@emanuelbriceno8776]

Is that sporwelder running on 3 18650 cells? That's impossible right? Good video!

[@haroldthibault9921]

Where did you get that cell staggered black plastic spacer. We usually find square plastic spacer. with yours, it seems we can pack more cells in less space ?

[@yousun2827]

Do you need it? I can sell it if needed.

[@mikex8254]

Is there risk of electric shock to hands when cells terminals are physically touched whilst battery cells are joined together in series at high voltages 48v and above?

[@yousun2827]

If the hand is wet, there is a little bit.

[@zidmerihai]

Nice

Yousun please do reply is your 18650 battery pack works perfectly aur it has great capacity loss after a year or 200 cycles or charge and discharge

[@DotsCreations]

Super

[@antonioarinascimento5748]

shoou muito legal essa maquina de solda você conseguiu onde

[@Mr23GB]

If I were to use a step-down converter to convert the voltage output to 12 volts, how many "amp hours/ah" will it put out at 12 volts versus putting out 20ah at 48 volts ?

[@yousun2827]

Buck efficiency, About 18Ah.

[@dashuslab3316]

Wonderful work, are you using a professional spot welding machine or it's DIY? My DIY welding is not so good.

I like the natural background. I watched the whole video but there is something you didn't show us. The connection of the green wire to the BMS. And also, why is it 47V only?
