Very professional. Nice spot welding pen. Best battery build I've seen yet on RUclips
Дай БОГ тебе здоровья, лучше тебя НИКТО не показал, для таких чайников как я!
Você não fala nada mas seus vídeos são os melhores da internet, não vi nenhum semelhante. Parabéns, yosun!
Wow, really appreciate the close up assembly and even without words, I learned to assemble a battery pack.
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

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.
Awesome video. The alternating colours on the balance leads I haven’t seen until now.
How much is the cost to assemble that?
I prefer individual cell fuses incase of a bad cell. Tidy job, impressed.
How do you go about individual cell wiring? Is there a video as good as this documenting it? Thank you.
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.
I will explain later.

Good job bro, even the BMS wires colours u used makes everything understandable thanks
Чуствуется правильный подход к сборке батареи,взято на заметку однозначно,пригодно к обслуживанию и ремонту в первую очередь,что важно в данном случае.Я в восторге
That was a really nice build with excellent documentation of the process. Great job!
instablaster.
I really appreciate your dedication to do it with patience
This 48V Li-ion battery based on 18650 is the most exquisite that I have seen! Thank you for sharing!
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!
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?
Felicitaciones , muy buen trabajo , saludos desde Argentina.
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...
I there some sort of spray silicone you can spray over your work after you finish you give it a moisture resistant surface?
Excelente video no nesecita palabras
this is an awesome video i learn a lot on how to weld and the connection of the battery awesome job.
Sem palavras.....
Parabéns nota mil
That was one awesome and satisfying video,
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.
Thanks!
El video está DEMASIADO BUENO!!! 👏👏👏🤯
vc e o melhor montador de bateria ate agora perfito muinto bom.
Esse é um artista!!
Like Brasil 🇧🇷
Nice video and y9ou do nice work on your packs! Thanks for the video.
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!
Отлично, всё понятно без лишних слов
Trabalho profissional. Perfeito. E aprendi a soldar a BMS.
Thanks!
Очень аккуратная работа
You are a great master of science and technology 👍 I respect you
Excellent
Which spot welder are you using
Thanks
Muito bom seu trabalho, bem organizado, essa de 48v 20 amperes
Is that sporwelder running on 3 18650 cells? That's impossible right?
Good video!
Great one, I need it so urgently. Thanks for sharing !
哈哈，yousun ,很有意思的名字 ！"您的太阳"的确！！china观众
What kind of welder are you using? Good video. Good luck.
Hi,
thanks for an interesting Li-Ion Pack building video. I build my own, so I understand the time involved and extra time to film it.
Some comments;
Pros; Nice professional build using what looks to be top shelf spot welder and equipment.
I like the way you built the layout of the pack and left cell holder openings that are protecting the connections.
cons;
Imagine the work required to take that pack apart if there is ever a bad cell or poor spot weld.
Note; I did notice you check EVERY singe connection to be sure they were all properly welded.
Once again, color code wire problem.
BTW; the DC electric world as I've always know it is Red is Positive and Black is Negative. China doesn't seem to have a clue about that.
Is that Blue wire positive or (probably) negative. And I can't really tell where it is connected on the BMS.
VERY important steps you left out for us DIY folks.
You show x2 48v voltage tests but don't show where the connections go! :-(
Also, between the shrink wrap, Barley paper and tape, you've sealed it so well, there will be NO cooling air able to circulated around the cells.
Here in the desert of Southern California, that could be fatal to that pack.
Don't take my comments wrong, it's few and far between seeing decent videos on pack building and all involved. I give you high marks and only hope to see more in depth info on the subjects I addressed.
cheers

OK! Thanks!
Hey Boots, Im in PB, did you make a spot welder? Im gearing up for battery building and could use some tips and info, thank you

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
Boa tarde! Tudo bem? Qual nome dessa embalagem e depois como abrir e lacrar de novo

감사합니다
Why you are not using fuse in the positive side of the battery? Is this safe?
There is some Nickel strips with fuse incorporated to the positive side.
Why you are not using buss bar?
The use of fuses causes serious heat generation, which affects efficiency.
Apka jo spot welding he o ap khudne banaya. Agar app khud ne banaya to uske upar ek vedeo banaye
Very clean work. Thanks for sharing!

Realy nice for DIY welding machine...
Thanks!
I Wont Say UR VideO Is Nice., It is Awesome., Way More Professional., Keep Rocking Brooo..!
Класс ,может и я когда нибуть такой апаратик приобрету.
OK!
Hi - what is the model / PN of the black plastics cell holder? I like the edge and spacing... most are just plane round on Amazon.
This product is relatively rare, and it is no longer available.
Thanks for this. What size was the blue PVC Heatshrink that you use to wrap the battery pack?
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 ?
Buck efficiency, About 18Ah.
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 ?
Do you need it? I can sell it if needed.
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?
If the hand is wet, there is a little bit.
Que ferramenta é esse que usa para gripar a bateria na chapa
Can you please supply links for all the items in this video including spot welder setup
Wondering why he only connected positive side in parallel and not the negative side, I'm learning about it.
Would you please list all the material you used to do the pack?
Parallel connections need to be thicker and stronger than series Connections.
For safety, to prevent a short circuit inside a battery.
Pls wear gloves while soldering u are doing very nice job
nice work but its missing a power level meter. the batteries i made are 4s's with a 20 led power meter using tl431
Electric bicycle has a power meter.
@@yousun2827 i still like the power meters on the battery because i use the battery for more than just a bike discharge. i bring them inside and hook them to other batteries and solar chargers as well as using them to power other devices at home and knowing the battery levels in any and every situation in realtime is much better
Good
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?
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.
Olá boa noite sou novo aqui então gostaria de saber se vc tem vídeo de como montar uma batata de lítio de 72v 40 ou de 50ah
By creating such a bank, we can also install UPS
Isn't there a faster way to connect these batteries for 48V 20AH? My 12V 20AH sealed lead acid batteries in 2 boxes only has 4 battery connections and 2 connectors for easy handling to and from the trike. Just connect the 2 boxes for 48V and a connector to the trike controller. They are charged On or Off the trike and charged at 48V 20AH.
I have only lost 1 12V battery in over 2 years of full discharge cycle. I just replaced it in place and the pack is on its 8 month of use now, getting about the usual 60km per charge.
Very good, you can use a large lithium battery and it is easier to connect.
So how many of these would power something like a super soco?
Wonderful work, are you using a professional spot welding machine or it's DIY? My DIY welding is not so good.

Did I miss where the charging points were?
I had made a lithium ion battery pack rating 14.6v 30a with the same type of bms rated 12v 30a.can I charge it with a 14.6v 3a smps or i need a same rated lithium battery charger.please reply fast
14.6V 3A charger.
good job. Once discharged how will you load it?

Wie viel hast du für all diesen Spaß bezahlt?
請問總重為？ 長寬？BMS有含平衡功能？ 為何設定cut-off到53.3V呢？ 最大可以54.6V, life time考量？
23*18*7cm 5kg 截止电压53.3V延长寿命.
12:28 Sounds like a golf club swing. lol
Great video ! Hello from Ireland 🍀☘️🍀☘️ ! How does the charger work ? Why is the negative bridges through it? Many Thanks

Круто и всё понятно! Лайк тебе!!! 👍👍👍
Thanks!
@@yousun2827 ???
Englysh?
Hello, where did you buy the nickel strips to assemble the cells? Are they ready or did you prepare them? and the point welder, you could give me a reference Thank you
www.yousun.org/shop
Great video
I was wondering if you can make two cells like the one you made and connect the BMS parallel to each other ?
Two batteries can be connected in parallel with the BMS, provided that the voltages of the two batteries are close.
@@yousun2827 they should be at the same voltage level but after time of use it could change right ?
If the voltage changes indicate a problem with the battery, it is usually the capacity that changes.
@@yousun2827 thanks
Please make video on spot welding machine (how make) wihich you use

I liked the video. Can I download it to my own computer?
Beau boulot et merci du partage ✌️
That hole messed it up. But anyways can you give all the list of parts in the description. Much better if you could put the link where to get it. 😀
Buenos momentos para usted... Quisiera saber cual fue el componente electrónico que colocó al lado de la batería y si también tienes el conocimiento Para fabricarlo estare atento a su grata respuesta gracias
Es un BMS , controla la carga, la descarga y balancea las celdas. En aliexpress los puedes encontrar como BMS.
I want to know..what is that he is using to solder the bat together?were could I buy it?
I did not understand.
thats neat and clean work
shoou muito legal essa maquina de solda você conseguiu onde
mano eu eu tenho dois pacotes de baterias de celular vc ja montou algum pack com essas baterias de celular Samsung?
Perfect batt pack
tell us about this spot welder,what kinde of battery use for spot welder?I see 2S2P Hitachi.Can you weld 0.2 pure nickel?
Yes!
Подскажите пожалуйста, если вы в курсе, как называется аппарат для пайки контактов?

Very nice video, I love your work, all respects for you
what is the name of the tool you are using, to attach the nickel plate to the battery ?? please help me
spot welder
@@yousun2827 okay, thanks
Спасибо большое за видео
does the black wire go to a positive?
Please tell us the maximum life of the cell you are building
Avendo un po di batterie 18650 da 3.7v
E volendo costruire un pacco batteria per un scooter elettrico
La batteria che monta lo scooter
E di 60v 20ah
Come li devo montare.....
Quanto batterie mi servono e con quale schema montarle
E poi o trovato un controllerxhe protegge 60v e 35ah i rete
Va bene
Grazie dell'aiuto.
This requires more tools.
Why did u place the cell in zig zag style..why not opposite to each other, wat is reason pls explain
This is arbitrary and has no special reason.
Hello there bud. What size shrink wrap are you using for that pack. Thanks.
Sorry! I forgot.
@@yousun2827 it's ok iv got it now. 250mm. Cheers any way. All the best.
OK! Good.
PRO, PRO, PRO!!! THANK YOU
I noticed the video is around 17 minutes long. How long did it actually take you for the entire process? If you were able to do this under an hour I would definitely be impressed with your skill and patience.
Which bms you use in this bettery
Thanks for this... It takwa how much batrei ia need to be able to walk as far as 70 km using the 1000w dynamo hub
20Ah 50 km , 25 - 30Ah about 70 km.
Thanks so much for explanation
