Bro, very nice video. But I read in the comment section that you have modified the charging in the ups to charge the lithium battery pack properly. It would have been really awesome if you had explained it along with the battery pack making or made a new video cause it may be misleading for many of not pointed out that lead charging system is different from Lithium ion technology.
Please do not let the UPS charge the Li-Ion 3S Battery. The 3S has a nominal voltage of 11.1V and a maximum of 12.6V (4.2V per cell row) - The UPS will attempt to charge the battery on the Pb voltage standard which is 14.4V. This will take the cells way over 4.2V and the BMS will probably burn its resistors as it will attempt to stop the current from passing, entering the "overvoltage" mode. If you don't do that, at least pin this comm so that people won't do it either. Thank you. Nice pack, btw. :D
Instead of using normal batteries you could have used 5 amp li ion batteries which are also available yes they are 18650 and only 6 cells would have been needed to create 12v 10 amps battery pack and the ups is not made to charge li ion batteries let me tell you use a simple charger pcb and connect the 12v input of ups to the pcb circuit it will help to keep them safe along with the bms
It worked fine, but please check that the charging system of the UPS device may not be suitable for the lion battery. You have switched from a dry type battery to a different type of battery.
we can't charge Li-ion battery pack with Lead acid battery charger so I had to modify the charging circuit of UPS so we can get appropriate charging voltage and current.
As you make a pack, when connecting in Parallel which way is better way connect it in? Connect it in as square ■ or connect it in as straight Line ----!
no fuse on each cell means.. if one gets bad meaning short.. high current will flow from other batteries that are in parallel and we know how will it end in that case

Bhai sahab 12 volt ki Lithium battery banane ke liye Agar Kuchh battery 2000 mah aur kuchh battery 3000 mah Agar Laga De to backup Mein Kuchh problem hoga yah charge Mein Kuchh problem hoga ya Kuchh problem Nahin Hoga Achcha chalega. Mere pass 30 pic battery 2000+3000 MAH ka.
Не делайте так, логика работы контроллера бесперебойника не расщитана на контроль литиевой батареи и просто заменить свинцовую на лицевую черевато пожаром взрывом лития и никакой драйвер не поможет. Так литий не любит перезаряд, а в бесперебойника свинцовые постоянно под зарядом стоят. Так что как минимум бесперебойник должен контролировать батарею и при полном заряде отключать ее. А в случай отключения питания она должна подключаться. Так что с такими вещами можно без дома остаться.
Есть грамотное решение этой проблемы в виде снижения конечного напряжения заряда до 12 Вольт. Причем именно до 12, а не 12,6, чтобы аккумуляторы не находились постоянно под максимальным напряжением. Я ставил литий в бесперебойник 1000ВА. Там используются 2 свинцовых аккумулятора, соединенных последовательно. Напряжение заряда по 3,9В на банку при использовании батареи из 7 секций по 4 банки. Полет нормальный. Встроена плата ВМС с контролем состояния по блютуз.
I tested 5 brands UPS crarge only 13.53~13.75V. The bms will cut charge when battery 12.6~12.9V. But UPS will stop output too early when battery still have energy but volter is low for Lead-Acid Battery.
🎉 I will try. How much tries before a successful battery pack :-)) 😊 First, to gather proper tools. Come back next year after many trials and dispointments (if still alive 😂). To thanks gor this very good pedagogical video.
Lithium ion batteries need a CC CV charger to fill their juice. Others may lead to an explosion. The way of handling 18650 lithium ion batteries is needed to be safe.
Ese no es problema. La ups solo permite de 350 a 500 ma para cargar la batería. El problema que yo veo es, 1, que el pack soporte la misma descarga que la batería de acido plomo. Y 2, que la ups maneja mucha temperatura por el trasformador, la cuál eventualmente llega a la bateria. Cuando se termina la carga de la batería de acido plomo con una PC , esos cables se sienten muy caliente(+ y -). Me da miedo que esa batería vaya a hacer explosión en algún momento por temperatura
That's not the problem as your laptop and phone gets even much hotter than this during high operations. My main area of concern is that the pcb should have thermal cut out sensors or sensors that can be attached to the battery body from the pcb. Like we have a laptop and power bank batteries.
Lead-acid batteries use the (CCCV) charging method. so ya can replace them with lithium batteries. plus the IC board is going to protect and maintain the cccv more accurately
Yeah, I will say, I don't understand exactly what the circuit they added does or how. But i do know messing with home made battery set ups, lead to lithium battery explosion and fires. I'm sure there are safe ways to do this, but...not being an expert, I can not tell if just adding the circuit makes it as safe as factory made batteries, that are made under approved factory safety standards. This maybe okay, but it also may not, so i personally wouldn't buy or make this.
That's not a wise idea to change the battery chemistry of an UPS without adjusting the controlling circuits. A 12V lead acid battery is meant to get fully charged at 14.2V (discrete) or 13.8V(Continuous). That's way too much for the 3C Lithium Ion Battery pack. You need max 12.6V. The BMS will protect the cells from overcharging to some extent, but you will surely never rip out the full lifespan of those cells. The low voltage cutoff of the UPS will trigger sooner than it should for the Lithium Ion battery pack and you will never be able to fully utilize the full charge of the pack (it can go as low as 11.1V but your UPS will likely cutoff at 11.7-12.3V leaving just 0.6-0.3V headroom for the batteries to operate (12.6V fully charged - 12.3V cutoff). And if there are charge indicators on the UPS, they will never turn green to indicate fully charged if the battery is replaced without circuit adjustment. So, such a battery replacement is not practical without carefully adjusting the charge/discharge circuits.
Good afternoon Tapedra My name is Laerte, I'm from Brazil, I would like to buy the PCB board already assembled to solder batteries, but I don't know how to configure it on the website to order it on the website. If you can help me or sell me one already assembled. Gratitude
My Ups gives continues ticking (not beeping) sound and not charging. I opened it and I think,sound comes from relay. I don't know the problem. Also tested the voltage at battry charging point it is 6v . Please help me.
I remember you from newspaper. Good to see you back.

It will work for a very short time because the rated voltage of the UPS is between 12 and 14.5v. This battery can't even put out 13v.
You are a professional so you did it easily but please tell that how dangerous it can be if even a small mistake is made.
It looks simple to do it, let me try how simple it is for me , I will do this weekend! Nice video
How did yours go

Nice upgrade from lead battery to liion battery pack
What about coolant to avoid overheating and fire?

Wow excellent
But it's need charge how do we do???????
I have a question: charging a lead acid battery and charging a Li-Ion battery pack(12v) with BMS needs same voltage and current ?
we can't charge Li-ion battery pack with Lead acid battery charger so I had to modify the charging circuit of UPS so we can get appropriate charging voltage and current.
@@tapendramandal Brother, in that case you must warn makers about it. With all due respect to your creation.
What is the soldering device called? And how i get one?
Very good 👍 ❤ Allah ap ko ترقی dy

Lithium battery need heat dissipation, can try HUATQ thermal pad😂
What is the name of the device you are using to join (solder) the component to the battery.
no fuse on each cell means.. if one gets bad meaning short.. high current will flow from other batteries that are in parallel and we know how will it end in that case
very good work master
Great thank you... Please What is the name of the welding machine you use
How are you going to charge this without properly balancing each cell?!
Could I buy one from you or is there a kit available
How I can charge 18650 battery can I charge them with module of powerbank ? With bms for security

Lithium ion cells cant be charged like lead ones, max voltage is 12.6 for 3s and ur putting around 15v, it will burn the bms
I tested 5 brands UPS crarge only 13.53~13.75V. The bms will cut charge when battery 12.6~12.9V. But UPS will stop output too early when battery still have energy but volter is low for Lead-Acid Battery.

What is the maximum instantaneous current that the package can supply at 12Vdc? Can you start a car engine in an emergency?
Normally it's possible, but dangerous

Probably there is some short circuit on pcb or damage component
@@tapendramandal I think battry is dried out, put some battry watter, but that didn't work.
When I change the battry with another one ,output is good working, but not testing with charging, because that is a lithium ion cell pack ,
