- These circuits are most important for '18650' batteries because if we discharge them deeply they loses its capacity quickly and may not able to charge them again. so if we add this circuit (BMS) it will cutoff's the o/p supply when the battery is lower at a particular voltage in my case it cutoff's at 2.35v and it also works as short circuit protection.

Brother you don't mind if I may ask, where are you from? Which country you are from? Hope I could fly to your country one day to meet up with you face to face hehehe, you are really one in a million GENIUS and definitely an extremely RARE tip top GURU in these complicated yet very important gadgets!!!!!
Brother, which is the best battery module in your opinion and your guidance, could you pelsee guide me please please!!!
Hello sir thank you...
Can you please tell me what is ,t, the middle out on battery
Hi! Though the idea is not very unusual I really liked your neat soldering. It is really not often one gets to see some neat work at basic levels as people usually get carried aay by the bigger ideas and tend to forget the basic steps. Thank You for reminding that "Triviality makes perfection but Perfection is no Triviality".
Thanks for visiting me, I have joined you. This is awesome, as you know I'm a micro scrapping woman who processes e-waste whilst having a giggle doing it, I have never retrieved these, I will now, this was very clever!!!! 👍

Can i safely charge Lithium ion Battery using this bms? Directly from mobile charger? When battery is fully charged dose this bms stop charging?
Yeah man it was designed to cut off the power when the battery reaches its peak voltage
Bhai aaj hi subscribe kiya tumhe aur yeh dhansu video feed mein aa gaya. Thanx bhai. Best of luck for your future. Keep posting good stuff.
Ek baat aur batao bhai, jis end per multimeter lagaya tha agar wahin per 2 pin wall connector laga diya jaye to yeh batteries ko charge bhi kar sakte hain na?
@@varunkumar-hw5uo Ha jee kar saktehe good question 👍 you should try it.
Thanks for your intrest.
Have a good day Buddy :-)
is that the save cut off voltage for 18650 li-ion battery? and does any old mobile battery circuit function as 18650 li-ion battery charge/ over discharge protection modules?
Yes!
once low voltage tripped is there a way to get them "bms" active again?
i got battery shows 0v on tabs but when i measure battery -+ it's 4.0v bypass bms, so bms must be tripped..
Yes! It will activate the bms automatically when the battery voltage rises cause of high resistance, some bms should be tripped.
just use a jumper connect main + of the battery & bms 👍
@@DIYwithBatteries ok Thank's for the reply..i shall give it a go..
How to connect two modules in serie, to make a 2S ( 7,4V ) bms . Thanks, Jan
That's a good question just connect "+" (- +) "-" = 7.4V
Don't connect the battery in series, connect the circuit in series.
You can also find a charge indicator circuit in my channel go find out. you may need it, if you are working with 2S battery
Thank you very much: I will try this👍🤞🙏
I have a simple question if I do use a single 18650 connected with this module how do O know if its charged or how much time does it take for a single 18650 cell to charge with a 1000mah module
Normally it takes 2 hours for a normal 18650 cells and it also depends on battery capacity
Please Sir are these lithium battery protection module effective?
Why do these batteries sometimes get deeply discharged while these modules are attached to them?
No!
These modules are there to protect the batteries from deep discharge
What Is the name of that part u removed?.the top of the battery with prongs?
Mention it
where can i get the Ultimate welding practicing board and kit ?
just to practice that, is there such a thing ?
Haha.... Yeah you can find it in old mobile batteries.
Just to practice lol :D
@@DIYwithBatteries oh i meant other thing, but actually thank you sir
I have another serious question though, does this part in batteries from certain phones to other? Like is this part of samsung galaxy s2 differes from lenovo A2010a phone's battery? How can i tell ?
They have different resistance for different types of mobile batteries but functioning is same :D
@@DIYwithBatteries thanks
Does this protector module prevent the battery from short circuit. If I short circuit will the circuit module prevent it by cutting off current?
Exactly! 👍
What is the max discharge current of those bms?
I need a bms with 3 amps discharge current. Can suggest one for me please?
Connect them in Parallel 👍

Can I use swollen battery for protection??
Yes you can, if you reset your battery ;)
Can i connect 5v charger in that bms pw+ and pw- point? Plz reply me😥😥
Yes! Of course & it designed for 5v didn't you watch the whole video lol
Can I conect this BMS on 6 cells to parallel one cells is 2000Mah. 6 Parallel cells voltage is 3.7 Volt
Sure! Just make sure to use less than 1Ah load even to charge it. 👍

@@Sheikhadnan67835 it takes hours but that's good slow charge is good charge 👍
Bro what is the overcharging protection voltage ? At how many volts it stops charging?
4.20v! 👍
Can u use this module to charge the bowerbank, than after it fully charged use same module to charge the phone
Using 5 same type of batteries
@@alialiharb8941 yes! we can use this but the i/p current should be low for high amp batteries.
Thanks for watching! Have a nice day.
may i use 3cell (18650 ) in parallel ?
Sure 👍
In this way, how many 18650 batteries, we can charged?
We can use as many as possible but it can only handle upto 1.5Ah max (better to use 6 cells as I'm using) use charge/discharge and if we draw more than that then it'll won't work!
I hope you'll figure it out.
Good question btw 👍
Are all smart phone battery module ,same voltage ?___if you take 3300Mah battery module ,on a 4200Mah is it going to reduce the amp to 3300Mah, what will happen?
Nope! The voltage is difference a little bit between 4.20 to .30v it depends on the quality of the boards.
They are also depends on the mAh of the battery and yes it may decrease the mAh little bit.
O vídeo é excelente. Só não achei o diagrama, pois estou com problema de vista e não consegui ler o valor do resistor que vai à lâmpada de led usada para descarregar a bateria e nem a voltagem/amperagem usada depois para carregar a bateria com o protetor. Obrigado pela atenção e forte abraço do Brasil.
valeu cara me ajuda muito ;) e não deixe de assistir meus outros vídeos espero que gostem Haha
Hy, can you pls tell me how to make this protection charger safe for a 350mah 3.7v lipo battery from a disposable vape pen? I have no knowledge but I have a t100 and I like to solder.thank you!
Cool just a resistor to reduce the current from the charger.
You can use 3ohms 👍
Because I was thinking of this XIAOMI battery module is only to control XIAOMI battery, but when I saw you connect TWO pieces of 18650, so I see hope in you after watching this video, but my main concern and worry is, can this XIAOMI battery module able to CONTROL a total of 6 or 8 pieces of 3400mah or 3500mah x eight pieces of 18650? Will this XIAOMI battery module cannot control a total of eight pieces of 18650 and in the end my smartphone and batteries EXPLODE?!
Make sure to avoid Short circuits ⚡
Can we use 2 batteries in parallel in this bms
Plz reply as soon as possible. It's important for me
Sure! 👍
Thanks 👍👍👍👍👍👍👍but can this board protect the battery from overcharging ?....The is the best video 👏👏👏
Good question , use a capacitor instead of a battery and it cutoffs at 4.3v maximum i already tested it but i didn't shown on video Thanks for ur intrest🙏.
@@DIYwithBatteries show that in another video...it already protects from overcharging I think..
Does li ion battery(round shape) has its own protector in it as shown on some videos?

Bhai replay dena jo Aap ne Battery Tod diya Wo damage ho gai thi.......
Ohh yes bro! the battery was expanded a little bit so i made a small hole on it, but now it's not useful anymore.
Thanks for watching my video Bhai...
How many volts did put to charge those parallel batteries and how many hours too?
5v from normal mobile adapter.... And it taken 3hours to charge.
And also it depends on the capacity of the battery!
Do I need to equal the same voltage of the other one to be charged? beacause if their not equal at voltage it might be overcharged and the other one is undercharged
@@dioemiltoh5551 Yes! you have to (balance) equal the battery voltage if it is connected in series.

how we connect 3 module together
for 4 lion 3.7v batteries
The polarity should to be parallel if you are thinking to connect your batt in parallel & if it in series then de batt series too, but i don't know if you're going to use different modules
Anyway May be it could helps I think ✌
Hi hello brother, I sincerely hope I could get your reply. I have a plan, a project, I believe you saw many TH-camrs been doing a kind of project, they use 4 to 6 pieces of 18650 batteries, connect together and use it as a direct source to power up their smart phone. And when I saw you connect 2 red color battery in this video, OK brother, my question is, in this video,the battery module you using, can control how many pieces of 18650 battery? For example, my plan and project is, I would buy 6 to 8 pieces of Panasonic 18650, one Panasonic battery rated at 3,400mah x 6 = 20,400 mAh, or 3,400mah x 8 pieces of Panasonic 18650 = 2,7800mah. May I ask brother, if I connect 6 to 8 pieces of Panasonic 18650 or sanyo 18650 x 8, can this XIAOMI battery module able to control my 6 or 8 pieces of 18650 such as, to control the 8 pieces of paradell 18650 battery charging cut off at 4.2v? or it will be very dangerous?
Firstly I appreciate your cmnt 👍
Yes! You can add so many 18650's as much as you can and it doesn't matter what type Or MAH of the battery, but it's only matters how much current you draw through this module, cause this can handle only 1AH max... (Normally) Even charge Or discharge. So make sure to avoid more than 1amp loads.
Thanks for watching Brother! :D
@@DIYwithBatteries OK brother I am confused of what is mean 1ah load? So, how do I know my smartphone will draw how many AH? I think of either I use 6 to 8 lithium 18650, or I will buy one LI-POLYMER 20,000mah powerbank and use the li-polymer battery connect to the battery module, then direct supply the power for my smart phone
@@DIYwithBatteries brother can you explain to me in layman term because I stupid and not very sure about the eletric. Brother, I don't understand what this two means:
I don't understand this two you say, brother, can please please explain to me in layman term
1) this module can handle only 1AH max and can "make sure to avoid 1amp loads"
2) so make sure to avoid more than 1amp loads
What does this two means, brother please please help me!!!!!
sorry buddy how many battery you can put in paralel? only two?
We can use only 500mah either charge Or discharge, so it doesn't matter how many batteries we're connected in parallel.
Haha... 👍
@@DIYwithBatteries I took it from a 3000mAh smartphone battery (samsung core prime) you think is the same or highter
@@christianepremian5322 I think it's a higher Or Quality board. Although We can use max... (1000mah) 1Ah for all type of mobile batter..., But it's better to use 0.5ah for long life. 😊👍
So whats the purpose of this module?
Can we charge the batteries with this?
You can reuse the old bms circuits from these flat cells 👍
Good
Thanks man!
Nice video, i have some questions,
So i did this with my tablet battery and it started for some time but battery was low so i start charging it by usb, problem was it was heating up but no malfunctioning, after full charge i left it on overnight, in morning when i checked on it the tablet was completely drained.
So my questions are,
1) Can i charge the battery with different module?
2) Will it work if module is Designed for lower mAh battery than what I've connected to?
1) Sure you can use any other module!
2) Nah.... choose better one like samsung Or mi battery module cause they can handle high current 2Ah max, and we can also use normal modules but the charge & discharge current should have be low, sometimes lower than 500mah
Thanks for cmnt bruh and i would like to answer if you have any doubts. 👍
@@DIYwithBatteries thanks dude for replying. I have no doubts but one problem,
I know this is completely off topic from your video but i need help with my tablet, the problem is, i have a tablet with dead battery so i bought new battery couldn't find the same model but same volts problem is the new battery have only 2 wire positive and negative and my tablet have 4 the 2 extra wire are for temperature and id,
So i am now trying to connect the new battery on my tablet but no success,
Can you tell me how can i start the tablet with this new 2 wire battery instead of 4.
Use a resistor (1k) , connect it with the 2 pins which are id & temperature, but firstly you have to check the resistance of those two pins connecting with -ve pin of battery in series. And then you have to check out the pin which have a low resistance and then cnnt the resistor with -ve pin in series.
"And then you have to check out the pin which have a low resistance and then cnnt the resistor with -ve pin in series."
Didn't understand this part. Can you describe it more precisely.
Varry nice
So instead of buying a TP4056 module, if i connect 1 of this taken from an old cellphone battrey to a 18650 li ion, this would work the same as a tp4056.
But not exactly. Because the current limit is very low for these boards. So better use TP4056 to get max load.
Thanks for watching!
How indicating battery full charge
There is no such type of indicator for this Board, we have to use Mutlimeter.
But im gonna make a separate video on it.
stay tune... Sir!
Bro is it safe to charge the cellphone battery directly with the 5v adapter? Will the protection circuit strip prevent excessive charging?
It's safe to charge it with 5v adaptor but you have to disconnect when the battery is at 4.2v !

Bro does this board regulate voltage of batter
Yes Buddy it will regulate the battery voltage at 4.20v, if it is higher then that it will disconnects the i/p from the Power adaptor.
@ Better use a regulator of 3.7v to 4.20v max.. just like the battery needs If you use above voltage it will blowup your smart phone.

Hi, Im Ryan from Indonesia
I have question. I want to replace my sony Xz2 Premium battery (3400 mAh) with other battery which has higher capacity (like 4000 mAh or 5000 mAh)
1. Can I do this method? Dissassy' my sony battery n then take the bms to replace bms on the new battery.
2. Do I need to re-calibrate the battery on my phone sony? If I need to re-calibrate the battery, what should I do?
Thankyou sir 🙏
I think yeah you can use the old sony bms by connecting it with new battery cuz it just ok if there is 1ah difference (low or high) but if your new battery have more then that then u can't use, it may disconnects the power when you increase your mobile brightness either than that it works good I hope 👍
can i use this for 2s configuration?

I don't understand this two you say, brother, can please please explain to me in layman term
1) this module can handle only 1AH max and can "make sure to avoid 1amp loads"
2) so make sure to avoid more than 1amp loads
What does this two means, brother please please help me!!!!!
You can use it for any mobiles which can draw 1AH max... But if you use more than 1Ah load like example: LEDs, motors, or any other circuits.
You can charge your Panasonic batteries with 5V 1Ah mobile adaptor and don't use more than 5V.
I would like answer for your questions Buddy no worries. 😊👍

Brother may I ask, if let say I build a 20,000mah battery be it I use lithium 18650, or I use a 30,000mah LI-POLYMER powerbank, and I tear down, open up my 30,000mah powerbank, take out the 30,000mah li-polymer battery from my powerbank, and solder with your this battery module, can and safe or not? I mean if I glue 6 to 8 lithium 18650 behind my smartphone back case, is going to be very heavy. So I thinking, if I can use my 30,000mah li-polymer, instead of using the 8 x NCR18650B (Panasonic)
