thanks alot، was so helpful.
Thanks
If two batteries charge before the third, the third charger Will get all voltage, só it Will burn,,, consider that current stops While batery is full.
ang galing itry kondin yan converted pede sa 5v charger and 12v charger double purposed sha great job brother
Thanks bro
Das gibt ein tolles Feuerwerk!
Thanks form Bangladesh
Welcome bro
hi can we use 1s 3a circuit instead of this one to get high amp
👍😍😍
Kids, don't try that, it will only damage your batteries and charging module. Be safe when play with li-ion batteries and get a proper BMS and charger
if this method is true so why you don't complete the video until all boards shown blue lights ?????
Nice work
You best
Εσύ ο Μεγάλος
The charger should be 15 volts so that the batteries reach 4.2v
12,6
if i intend to charge all 3 at the same time using 1 usb port (5v), can i solder them in parallel rather than in series for the 12v charging?
the problem I see here is that the batteries are not connected together so there is not a battery pack as such, joining them together to make a pack of ~12v battery pack would short the diodes out and make them redundant...
I'm no engineer, but wouldn't the output of the modules be virtually the same as soldering or welding the cells together, but instead they're individually protected?
Good job
Wow you're a genius
Use a proper 3S circuit board to manage the battery charging and discharging.
There's many flaws in this design, as these boards are designed in mind to handle only one battery at a time.
What you can do safely?
Wire them in PARALEL not series with a source of 5V - 3Amps, and charge batteries in paralel without any connection to each other board.
Pero tengo entendido que un BMS solo controla la descarga, mas no la carga, y si no fuese asi que codigo de modulo BMS recomiendas??
@@jorgecarlosmogollonrojas5536 BMS should implement safety triggers for both charging and discharging.
BMS should be used only for what it is designed for, like 1S BMS only with 1S battery, 3S with 3S battery and so on.
You can put the same cells in parallel to increase the capacity while maintaining the 1S, for example, put 3 cells in parallel they are still 1S.
IMPORTANT: Cells should be from the same lot (manufacturer, year, same usage, preferably new), and balanced when you put them together (have same voltage).
It is, even like this, unsafe, as the BMS designed for 1S 1P (1 series, 1 parallel) would not have balance charging along all the cells put in parallel, but let's say if you respect what I've said (same lot, manufacturer, year, date, usage-preferably new), you are quite safe for 2 or 3 cells in parallel.
I either saw a TH-cam video showing a person wiring these BMS boards in parallel or figured that out after seeing something similarly mentioned. I also saw in a video where someone applied thermal plaster and a small heatsink to limit heat buildup in larger 1s setups... still took the TH-camr like 7 hours to charge the battery, but was able to constantly output 1amp safely.
I never intended to follow this project, as I remember hearing of all the difficulty and risks of getting a few BMS boards to work together in series (I bought about 20 or so of these Lipos that are thin, like phone batteries, and come with a decent BMS installed already).
@@Suzuki_Hiakura It's not about heat, thermal safety or similar.
1S BMS can't handle balance charging, and can't current limit the output properly and so on.
If the piece of hardware is not designed to work like this, and imply a possible fire hazard, then don't use it like this.
@@overPowerPenguin the first part of my comment was referring to your closing statement. My second part covered what I heard of using simple 1s BMS boards in series.
bro mere pas 3 different types mah ki 18650 batteries h kiya mai power pack bana sakta hon with bms?
Hi Dream Finder. These individual battery protection circuit boards can handle a max of 1 Amp. Would there be a problem if I make this same 3nos series circuit for 3nos 3.7v battery and use it for my UPS? The problem I am concerned about is if the UPS 14v charging voltage is 3 or 4 amps. Would it blow the circuit I have made? What is you take on this?
i used a separate charge source for the 12v batery pack. and use a full bridge rectifier on the battery to ups. that way the ups can't charge the battery but can draw power from the pack.
Батареи не соединены вместе. Если их соединить как в батарее электроскутера, произойдёт короткое замыкание.
hi I have a battery that already has a protection and the question is will this cause a problem if i use a charger chip that has another protection?
I have Four 3.7V 1800mAh li battery packs. If I wire the four 1800mah cell in parallel to make a 7200mAh cell..which type of BMS i need?plz give me Order Link 🙏🎉🙏
Ciao, ho fatto il collegamento come da video, ma, usando un alimentatore a 12V vedo che una sola luce blu si accende dopo molto tempo in carica. Uso un alimentatore 12V 1 A. E' forse poco ?
If you comment you will get a ❤
Nice job bro
Kiya me is circuit se 12 v lithium cells charge krsakta hun?
It will never give 12v...its almost 11.3v ...bcz voltage consumed by two diode is 1.3v and .66 for each.
Hi, I loved your project, excellent, congratulations. I would like to use this idea of yours. Could you please answer some questions for me? I'm going to replace the 6v lead battery of a children's electric motorcycle with a 18650 lithium battery. I'm going to make a 2S pack. Can this project of yours be done with just two cells? Will I have to replace any components? Thank you very much for your attention. I wish you to continue with your projects. A hug
dear bro this experiment project, please use 2s bms for charging of babies bike.
i think the motorcycle wil pull to much amps from the circuit. they can only provide 1amp i think.
Sir, can I use this method to make 4s BMS... I want to make 3.7x4 ups for arduino with dc step down module (12v)
use 1s battery pack and step up module
It is better to buy the correct BMS. A 3S 40A Balanced BMS cost $1.23. Not worth the hassle to do your own...
Actualy its fine a single module ,it depends on the amperage of the batteries, its just a security thing
Tried this exactly with diode.....but the last MODULE keeps getting hot on idle.
Changed the module....but same problem...
What can be done....
..
How can be with reverse voltage of full battery on the closed BMS transistor in discharge mode?
I've no experience bro
With that connections you are actually shorting the chargers as you see when you plugged them in the chargers that has the current led on , (red led on), cause you are shorting them with the connections that you made so its a bad idea to use them like this.
Keep doing videos but learn from your mistakes!
If anyone needs anything from this, please get in touch.
Another vid introducing bad ideas to people, knowing even less, than the originator:
Sure: connecting the single boards this way charges 3 cells at the same time, but you win pretty much nothing, apart from using a 12V source instead of one 5V source with more ampere:
*) you still cannot use the charged cells as a 12V/11.1V 3s-power source.
*) What about the charging current? IMHO it is limited to the current of the slowest cell. And what happens, if one cell isn't present at all?!?!?
*) no real balancing function
*) 12V will not load the cells to their limit of typical 4.2V, but rather 80% - IF cells are being drawn equally.
*) the role of the diodes is not explained, nor the type/their voltage drop They look like some 1A+ type. (didn't look them up)
*) soldering the cells instead of changeable slots -> if the cells are used quite differently, at a current >> the one the 4056 can provide --> smoke?
The 4056 allows for different charging speeds (via changing some resistor on the board) - it'd be much more interesting, to have add a switchable current/capacity charger.
Singal charge kare to
Out put series me or input charger se de to separate
The video is not complete. It left the viewers in confusion. There no explanation as to how it works as a 3s bms or 4s bms.
It's difficult to maintain input voltage, so use separate BMS
@@DreamFinder eBay. Makes this arrangement as a junk.
Sir I want to make 4s battery one like you so can I charge it with laptop charger?
what is the input voltage you given to this 3 modules
12v it's in the video
That Good...!!!
Thanks
Amp.kya 7 ya 7.5 hoga
Sir beech wala me dono indicator on kyo hote hai charging time
Готовая плата мягко говоря лучше, учитывая сколько она стоит. Она ещё и как защита работает, а тут ерунда полная выходит
Если одна плата уйдёт в защиту, она тут же хапнет напряжение обратной пооярности на выхода
Хоть бы диоды поставил на выхода (параллельно выходам)
How can we do the same with Solar charge controller?
diodes causing V-drop and as someone already said you can power them in parallel /
The correct when using the TP4056, is to connect in parallel, feeding with 5V and 3A or more, so you can load a pack 3s quietly without problems, because each cell will be charged individually. The B3 lipo chargers, use TP4056 in parallel.
I'm no engineer, but if you connected all the modules' 5v charge inputs in parallel, you should be able to connect one usb cable to charge them all at the same time, no? That way you don't have to mess with inputting 12v across the three or charging one at a time.
No you cant as these are not isolated converter, by doing so you will shortcircuit the batteries
This don't charge 3S battery.... but x3 battery by 1S... If you connect the same using 3S battery pack you will short circuit your diodes....
what if you dont install the diode? what will happened?
Nice
This is cool.
I fooled around with this idea but didn't think of diodes to isolate the boards.
This should be good as a low current battery supply (500mA) because the boards can only switch about 1 amp through their output circuits and the diodes are 1 amp. Each board contains two circuits. One shuts the input voltage to the cell off at 4.2 volts. The other circuit shuts off the output voltage when the cell drops below 2.9 volts.
Для низкого потребления пойдет!!, для больших токов, надо по другому.
it sure does work but you need several phone charger and avoid ground loop
Thanks
This looks like a really bad idea. FIrst of all, BMS = Battery Management System, the first modules in the video are BMS but the one that was chosen is a CHARGER. Second, it uses the TP4056 chip which was not designed to operate this way, and could cause all kinds of problems, including causing the batteries to get on fire or explode.
Thank you for your info. I agree.
Some mistake of you my dear, all bms are 1 sell, and supplying voltage of depend on total BMS voltage and it share with series.
@@DreamFinder ok, but TP4056 is not a BMS, it is a chip designed to be a 1 cell charger
thanks for the honesty. I would like to have your opinion on this thought. What if each battery has a its own protector board. like cellphone batteries. anyway the purpose of charging them with the proper 4.2 limit but needing the 8.4 +/- volts for instance of using 2. I assume not to try it. If not, could you guide me in the direction of figuring out how to use 2 cell batteries in a series and being able to charge them safe. hopefully a DIY way. i have no budget to work with
I tried & its burn a tp4056 module
Wow
In cello ka inpot uor out pot kaha se le hum kisi chez ko chala ne keliya
Sir apne jawab nahi diya
I want for 3×3 = 9 Cells for Activa Scooter. Circuit Chalega.
Bilkul aap 3 charging module ko aek sath laga ke 3s BMS bana sakte he

Master, how can I do 2s bms in parallel connection, please reply, thank you
I have a 3 S BMS. How can I use that as a 1 S BMS.. Basically I want to put 2 cells in Parallel and use a BMS for that. Need atleast 3 Ah output I need
Buy 1S Bms which are cheapest on ebay.
Pls explain what you are doing
See again
Good brother I'm from Pakistan 🇵🇰
How long have you been using this device an please be honest
It's really important I get a honest answer, I am working on something, an I need your honest answer
It's difficult for maintain input voltage, so use separate BMS Sir
@@DreamFinder thank you sir for replying sir, but I didn't get you, how do you mean sir.
Will it work really?
Not practically
Can I use 12V 2A adopter in input ??
It depend on total 1s module. Yes for 3 sell
Good project, but can i use two cells on each charging board?
No
Are Bhai jab 3 BMS lagane Hain to alag alag lagao
Output nhi dikhaya
How can i buy it?
No way bro
This is in NO way a BMS, this is at best a bad charger x 3. Using this will damage your batteries if not cause more serious problems
How to connect load? Link the boards or take individual leads then join them?
Batter
Can i follow this method for 60 volt battery
But only one time... 😂
These videos are really dangerous and shouldn't be here. Congrats for the cold joins and soldering different capacity Li-Ion batteries in series.
Thanks
Convert 20s to 13s
this is not 3S, you are charging the battery 1S, you just used 12v as input.. 3S is series of 3 batteries, and you are charging the batteries individually. misleading title..
Yo pienso lo mismo pero en algún momento mide el total de las 3 pilas y tiene los 12 V
the cells are not in series so its pointless. "edit" never mind i see what u did.
What is the AMPERE?
@Umar Farooq I meant how much is the amperage value.
1 or 2 ampere and 5 volt
Читер ;D
Ye kaam nhi karta
Tom na kara ha
Wrong all in this video
Dont do this It will blow
do not try it b/c is gonna fry ur tp4056
Dangerous
У кого спер идею!!?
Wrong wiring fake video
Koi fayda nhinmin ny try kia he
😂
Charge by 13.5 volt you use 12 volt ? Wrong
3S BMS under one dollar... This is useless!
Nice
Thanks
