Thanks for watching!!! Please don't forget to Subscriiiiiibe 😊.

Great work Thank you for sharing your knowledge with us. Stay well and good luck in your future. Ashraf from Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿

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".

How to connect two modules in serie, to make a 2S ( 7,4V ) bms . Thanks, Jan

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..

Please Sir are these lithium battery protection module effective? Why do these batteries sometimes get deeply discharged while these modules are attached to them?

Thanks 👍👍👍👍👍👍👍but can this board protect the battery from overcharging ?....The is the best video 👏👏👏

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

where can i get the Ultimate welding practicing board and kit ? just to practice that, is there such a thing ?

What Is the name of that part u removed?.the top of the battery with prongs?

Al extraer el BMS lo recicla ...pero que hace con el resto del material ? Lo que resta es altamente contaminante y peligroso

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.

In this way, how many 18650 batteries, we can charged?

What is the max discharge current of those bms? I need a bms with 3 amps discharge current. Can suggest one for me please?

Thanks for sharing 🙏🙏 Great idea 👍👍

Can I use swollen battery for protection??

Good

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?

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?!

Can u use this module to charge the bowerbank, than after it fully charged use same module to charge the phone

So whats the purpose of this module? Can we charge the batteries with this?

Bro is it safe to charge the cellphone battery directly with the 5v adapter? Will the protection circuit strip prevent excessive charging?

Nice experiment bhai... kya tum is battery ka backup nikal sakte ho kya ? if 4 v dc led strip ispe lagane ke bad kitna time chalegi plz make video

Varry nice

Is ko nikalne ke baad battery charge hoti hai aur ise use kar sakte hai kya 🤨

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!

You can bypass apple security for changing batteries by separating the circuit from the battery and soldering it to a new 3.7v battery 😉

Samar vay a kitna volt deta hay, mezar karne se achcha hota,

may i use 3cell (18650 ) in parallel ?

Bhai replay dena jo Aap ne Battery Tod diya Wo damage ho gai thi.......

How many volts did put to charge those parallel batteries and how many hours too?

how we connect 3 module together for 4 lion 3.7v batteries

Bro are the batteries able to charge directly from the charger using this module.

Ok felicitari

Very interesting, thanks. I think a voice explanation would be better than annoying music though...

Hello bhiya kya hun samsung C7 ka battery say bana saktay hay ?

sorry buddy how many battery you can put in paralel? only two?

Hi hello brother, I sincerely hope I could get your reply. I have a plan, a project, I believe you saw many RU-vidrs 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?

Meaning, one piece of yours this XIAOMI battery module, I solder all my 18650 lithium battery in PARALLEL, one piece of this battery module can handle and control how many pieces of my 18650 battery for direct source supply my smart phone?

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.

Kitne amh ka battery use kiya hai apne

HI, Can we charge lithium-ion battery with this module with a 5v mobile charger? please reply to me.

Thanks, and my sincere greetings Everything is understandable, but what is the appropriate electrical resistance value. Thanks again and I hope for a response from you

can i use this for 2s configuration?

bhai jaan samsung edge 7 battery ki stip tooth gi hai please uska method batye

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 🙏

Thanks for to show this experiment

How indicating battery full charge

Hope brother you understand what I am asking, in short, meaning, you connect only 2 18650 with this XIAOMI battery module, right? OK let say if I buy 6 or 8 pieces of Panasonic 18650 (3400mah x 8) or sanyo 18650 (3500mah x 8) can yours this ONE piece only XIAOMI battery module able to control all 8 pieces of paradell 18650, as in to control the OVER continue charging and control the CUT OFF charging once the 8 pieces battery already full charge? Reason because I wanna build a 20,000mah massive battery for my smartphone as a DIRECT POWER SUPPLY. hope you can answer all my doubts and questions, when you see this message and of course, when you free, trillion times thanks for your great help, please brother.

Buy a regular soldering iron. And learn to solder! Do not use such garbage tools. Trash it.

No explanation of what you are showing. Horrible video

Nice! I actually tried it, now thanks to you because you confirmed my work.

Can i safely charge Lithium ion Battery using this bms? Directly from mobile charger? When battery is fully charged dose this bms stop charging?

Actually that's not a DIY project

Please reply, brother please please help me! :(

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!!!! 👍

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?

Bro what is the overcharging protection voltage ? At how many volts it stops charging?

Can i connect 5v charger in that bms pw+ and pw- point? Plz reply me😥😥

Brother, you are the final last hope I have, and you are the only person who know all the answer I want, so, I beg you please help me for this question, 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!!!!!

With battary leble indicate

battery charger new- ​@​

Very good

Kya jis mobile ki battery ke circuit mein sirf ek hi IC Ho To Kya wo auto cut Karega circuit Aur agar mein Mobile ke circuit ko series Mein connect Karun To Kya wo Thodi Jyada voltage ki battery ko charge kar Payga

Also, brother, if your this bm41 MI battery module can only take the 1AH 5v adaptor, in that case, can brother help and guide me like for example, what other battery module I can use for support 2AH charging? But anyway if I can use my 30,000mah li-polymer battery and solder with your this bm41 MI battery module, I also already VERY VERY happy and very much appreciated and thankful to you!!!! Heheheh
