- Опубліковано 2 жов 2021
- Hello friends, In this video we upgrade faulty lead acid battery in to lithium Ion Battery. We used 3.7V rated 2500 mAh lithium cell to make this battery. We used 9 cell in parallel so we will get total 15 Amp. If you want to upgrade your faulty battery, just follow all the step and make your own.

Thank you. Very good job.
Made nice battery 👌👍
Thanks
Very nice and clean connections
Nice video, thanks :)
All the current of series and parallel cells comes together in one point and flows thru a single tiny nickel strip.
You definitely need thicker strips for series connections.
Tiene UD razón, por la suma del amperaje la salida debe ser adecuada a la potencia final entregada en las últimas conexiones.
Thank you and love you❤❤
Good good 👍😍สุดยอดมากครับ🌟
Thanks
You made a lot of work my dear and thank you for the video, but have in mind these: The lead-acid battery is cheap and can gives high current. By connecting small batteries in series if one goes open,then stops the current. If you connect batteries in parallel, if one shorts inside, it will discharge all the others. I would not do such thing. Very friendly from a Physisist.
People are building batteries from 18650 cells all the time, if cells are good, new or tested there shouldn't be any problem. They last a lot longer than lead acid battery. Ebike, car batteries they're all builded making series and parallel connection
High current but lower running time. Newer BMS have higher current output that matches lead-acid batteries.
من با شما موافقم من هم همچین کاراحمقانه ای نخواهم کرد یک باطری سرب اسیدی نومیخرم باهزینه کم وایمنی بهتر
@@clixium We are all used to make risks. If we're not poor is not a problem my dear.
18650 battery is the future of power storage, Naa think more bro........
Merci beaucoup pour l’explication
Bạn sửa bình ắc quy và thay thế pin vào thật tuyệt vời
It's cheaper and safer to just buy a new one. Beleave me. I am using agm as well as lifepo4 and lifepo4 are way more difficult to charge and mantain ballancing. Liion are even more difficult. You have no good (3s7p) bms (that bms is useless) for your diy battery so if one your cells discharges more than the other, when charging you will get some cells to be overcharged.
Not safe
Sawing a battery case? amazing
Good battery work🔋🔋🔋🔋
It will be big Fire in the Future!
I would be very cautious with this, because it does not comply with any regulation and in case of fire , Insurance company cold get difficult., why do this?, allso the charging electronics in the original device mgith not be compatible with this "new" self build battery , i myself would purchase the original batttery despite the nice work and this video, you are a very handy person.
GOOD tiching karte hai 👍👌👌👌👌👌👌👌👌👌👌👌
Good idea 👍 nice
Awesome bro I have a box of these dead batteries
Good, you can make
@@easytechzones how much cost bro approximately
Bagus pak ,Berapa kapasitas BMS maximal yang digunakan,versi balance atau yang seperti apa??
excellent job
I want to make a battery 24volts
14 amp
can you please show me the batteries arrangement and battery type
Do you need lithium iron batteries?
hello, does the battery point device you are using allow you to point with a lion battery
Super Ideas. 👍👍👍
ola bom dia, tenho vontade de fazer projetos desse tipo aqui, mas nao sei por onde importar essas baterias/pilhas, poderia por gentileza me fornecer algum link ????
این کارانسانهای نادان واحمق است
C’est formidable 🤝
Thanks for speedup
That's great
So, let me check I understood this correctly. First remove the old, dead innards. Then buy a new battery. Hey presto, you've upgraded it.
18650 cells wired together to make a big battery isn't just buying a battery though is is
Very Nice 👏👏👏
Good
Thanks
احسنت ستاذ 🥀🌷👏🌺🙋♂️💝🌹💕👍❣️💖💐✌️
Nice video.Why you took bms 45ah? battery amp is 15amh?
The BMS is 40 amperes and battery is 15 ah means 15 amp hours
C’est magnifique 👍
Amigo me gustaría un video donde enseñes hacer una de 30 amperios, además como calculas los amperios que te dará todo el arreglo de batería?
Veja canais Brasileiro sobre energia solar 18650
Para uma bateria de 30a 12v será necessário 14 células em paralelo,sendo assim precisa de 42 células.
Esta es una batería de 3 líneas/serie. quería hacer una batería de 12v 15ah. Hay fórmulas simples. 1 línea tiene 3,7 voltios. Entonces, 3 líneas producirán unos 11,7, que están cerca de los 12 voltios. Ahora el cálculo del amperaje. Usó 6 celdas, cada una de las cuales contenía 2500 mah. 2500 x 6 = 15000 mah es decir 15 ah. entonces, si desea hacer una serie de 30 amperios, necesitará 2500 mah x 12 celdas o 5000 mah x 6 celdas. El otro procedimiento es el mismo que en este vídeo.
AMI MOJA KORLAM TOMAR SATYAA 😂😂🤣🤣🤣🤣 KHUB VALO LAGLO THANKS
Welcome
@@easytechzones 😀
Well done, you probably could even have made it 7P3S with 3500 mAh per cell.
Will get good battery
Do all your batteries have same MAh..or diffrent MAh??
Please reply
hello dear sir frist thanks for this education video my question is , can we using three of this kind battery parallel together without BMS extra between them ?
Yes. Just check voltage before parallel connection. Required the same voltage of all batteries
Super bro👍
Thanks
I would afraid of some worse troubles - starting current 780 A - don't think these batteries will handle ( basic car battery has 74 Ah - not 15 or less )
Super bro well congrats,I have some 3.7v battery.sale me?
This not 100% replacement for 12v lead acid SMF battery .six cell lead acid battery full charging battery voltage and three cell lipo combination are not equal characteristics .where as lipo battery is 12.3v at full charge and 9volt @ 25% charge .lead acid battery is approximately 14v at full charge and 12volt @25% charge .
Yes correct ,use 4s BMS 16.8 Volt maximum

Good bhai ji
Puedes compartir el link para fabricar esa soldadora de punto casera por favor? Gracias!
That spotwelder seems very weak, normally 2x2 spots is enough for normal nickel strips.
It seems the nickel strips here are really thin because the spotwelder can't weld normal (thicker) strips.
At least for series connections you need thicker nickel strips than these.
سلام. میشه از سه سل 20آمپر استفاده کرد.
متشکرم.
منتظر جوابم.
Excellent project 👍
這個電池做好可以用來發動沒電的車子上？
i did same except just used cell spacers.... but my ups gets very hot for some reason when left on just charging......otherwise it works very well....can drive a few things for like 30 to 90 min.... i used old 28650 reclaimed cells....good job insulting each pack then the whole pack.
Ups charging section is designed for lead acid battery. Use lithium charger for the charging ...
Best video
Ok I enjoy videos like this….that being said you are using batteries rates at 3.7 volts. Yes when fully charged they have slightly more but not for long. So realistically it’s 11.1 volts on average. You were better off running a 4th row in series for 14.8 volts. I feel your setting whatever this is connected to up for failure.
Li-ion 18650 have minimum 2.8V and maximum 4.2V

How to make spot welding machine ??
Прикольно конечно но по деньгам выйдет как 3-4 свинцовых аккумулятора.
Да и его на старое место не воткнёшь, они как правило как резервный источник стоят, под постоянным напряжением, а там напряжение то 14,4, а литиевым это перебор...
@@Fedor___1 Плата контроллера заряда и разряда установлена, она не даст перезарядить батарею, хотя я согласен что это дорого и не заменяет полноценно батарею так как напряжение будет пониже обычного (12,6 только при 100% заряде).
@@tesladude2822 так она постоянно будет под напряжением 14,4, т.е. постоянно будет отключена, резервные батареи так подключаются.
@@Fedor___1 Я не знаю где именно применена эта батарея, возоможно в каком-то резервном источнике питания. Так вот плата BMS не даст перезарядить батарею, а если батарея подсядет она будет заряжать её до безопасного напряжения, но не более.
@@tesladude2822 ты не понял, батарея в резерве ещё и отрабатывает как большая ёмкость, а тут она будет всегда отключена! И напряжение в 14,4 В не допустимо при зарядке литий-ионных аккумуляторов.
How did you make the machine that you make soldiring (I don't know İts name)
Tedelacıda satılıyor Kaplama yap veya folyo yap rekli
Compensa comprar uma bateria nova que dá menas despesas com material e trabalho.
No, pero tampoco te sirve el del video pues usa celdas litio ion o poli que son de 3.7v y para algunos aparatos como SAIs/ups no sirven ya que daria 11.1v nominal y 12.6 pico siendo que la de plomo es de 12.8 nominal y 14.4v pico.
La solucion es usar 4 celdas de lifepo4 de 3.2v que serian 12.8v nominal y 14.4v pico, ademas de tener entre 2000 y 3000 ciclos de cargas x4/x6 de litio ion /poli aunque se pierda un 30/40% de capacidad en el mismo volumen.
kayaknya baterainya kurang ya bos, khan butuhnya 12 v tapi outputnya cuma 11 v ?, kalau dibuat aki motor, biasanya antara 13 - 14 volt....
pls show your spot welder
Nice video but bhai ise charge kaise karna hai
3.7 volts x 3 banks = 11.1 volts. Quite low compared to 12.6 volts of a decent battery.
Can we do the same with LiFePo4 battery ?
Yes
Where to you buy the batteries
Bmsกี่เซลคับ
This BMS can't hold on long time current above 20A without cooling (1-3 min maximum)... And nickel tape is too thin, it can overheat... So this battery is dangerous at high currents.
P. S. And You can't use it in UPS because voltage of charging is ~13.6V, but BMS turn off the battery on 12,6V and UPS - will say "mistake".
Sir ye spot welding . Prise
will it work on the original charger?
