Sorin, this is the first video I saw from you. You explain very well and make things clear so that everyone understand fully what you are doing. Thanks for the interesting video.
I just found your channel a few days ago and all your videos are great, informative and fun to watch. Keep up the good work!
another wonderful video. was wondering how these boards would behave in a series configuration. Thanks for this educational video!
Keep it up :D
You make the best tutouriuals. They explain everything, they have humor, and i can no problem figure out what are you saying. By that i mean your english is very good, near to perfect.
Thanks Sorin, I haven't solved the shorting on inputs of TP4056 until I saw this video. I constructed my own powerbank and UPS for my laptop...thanks a lot for your diagram and test done on your video. I had learn a lot from it. Keep it up!
Thank you for making these videos. They're educational and entertaining and they've made me comfortable enough to try some stuff that worried me before. Thank you!
Really good video. It gives us all a much better understanding of how these lithium 18650 chargers work, as well as their components.
I saw ur video first time and ur so informative thanks bro
Fantastic demonstration, really liked it.
I love the comic relief and jokes. I see you have an interesting personality
Great video....thanks. Love the technical skill mixed with humor.....perfect.
i did same thing using different 5v power supply from usb chargers up to 2A each, and used 2 TP4056 for each charger to balance batteries up to 2A, i use this to balance Ebike and electric bikes batteries, and really worked great for about a year, did one to balance up to 20s battery packs :)
Bravo Sorin cotinua tot asa 👍
asa..bate-ti joc si tu :p
learned something new about tp4056 boards 😄😄
wow Sorin your channel has grown since i 1st subscribed!! May it keep growing... class video!! just one thing the 2nd connection diagram you showed the TP4056 module's didn't have discharge protection just over voltage protection. there two types!! the better one has more chips(3 chips) on the board. for those of you new two this module & are looking them up/buying online, get the one with 3 chips on the board because it has the over & under charge protection. hope this helps!!!!
Yes, there're two type of this modules. The modules in the first diagram have also discharge protection and in the second diagram have not, because there are no output pins on them. They are only for charging process. The first module that never works again after short circuit can be broken, because the other three modules are still working. I wonder where is the output voltage of this module supply from. Is it show 5v when power in and the battery connected and 4,2-3,7v when only the battery connected, not the power in?
SORIN! You stole my idea for dedicated output windings! Great minds think alike I guess.... I was planing to use a toroidal transformer. I'll subscribe:-)
I was thinking of building something like this using hand-wound secondaries on a toroidal transformer. Benefit is that each "cell" is isolated from others so the outputs can be connected in a series string as in a Ebike battery. Also allows the voltage into each TP4056 to be kept to the minimum to achieve a full charge, to reduce dissipation.
Excellent. Thanks for your help. I have subscribed to your channel.
Good video, very informative. I'll be careful not to upset you, I don't want to get "a little busted". 1:03 LOL.
Very good project 👍
Nice project and your cat looks cute
Who used the cat as a star of the show first, Average Joe or Sorin the Nerd..hmmmm🤔...don't matter, both are geniuses and great to learn from. Love you both. Great video Sorin
p.s, put that cat on a high resistance training diet.
I think the idea is great and helpful.
I planed to build this for a while...
I am using imax b3 that work probably exactly the same way, but i dont think I can hook them up in series.
This thing wouldn't be a problem if you have 5 4s chargers... Just to connect them in series to get a 20s for a fast ebike for example.
The con is... Power consumption for thee transfermer... I was liking forward to see you measuring consumption. Before the transformer and after it and... And after the full bridge rectifier...
You have the best precision tool
Brilliant ! We to be a good friend of this guy after the Apocalypse.....

cel mai bun videoclip care exista pe youtube...esti profesor! good job! multumesc ca ai facut acest video!abia astept sa am timp sa ma uit si la celalalte!(ce rasa este felina?)
salut. birmaneza
thanks dude I was looking for this a long time.. I'm thinking to use that on my cordless tools, but that long wait time to charge batteries😞
That's an impressive soldering poker
Felicitãri, Sorine.
Good luck for 1M sub. Sir I guess you can get 1M soon have a nice day sir
Yuhuuuu ,felicitări!
what a,beautiful explaination at all the time,,,and a little bit funny,
and,,,speacially,,the verry cute cat,,
she? or he?
helps sorin for whats his doing all the time...
but,,,why?
is it get hungry?,hahaha,
thank you for the video sorin..
it been too long to wait another video again..
Bravo Sorin. Continua pana tot

Nice project and your cat too.
Nice video, thanks :)
I've seen people do this before. What they always miss is a diode across each charger output to avoid negative voltage going into the charger when one battery drops out under load.
Diode across the battery output B+/- or the OUT pins?
You can use separate phone chargers and wire the cells in a series. I did it.
another good project
I made last week video about tp4056 18650 battery charger.. works amazing!
could I use 3 step up boost modules to connect to the tp4056 from 5v instead?
I did that same circuit that you did, but with independent 5v switching power supplies, the problem is that when one battery cell goes below 2.5v with a discharging current over 1 amp, the TP4056 blows up, it will overheat and burn out, the charging light stays on and the 5v input now outputs the voltage of the battery, like what happens when you do the short circuit.
Salut,ai putea face in viitor un video despre convertirea unei trotinete normale intr-una electrica?
Super video!
Sir, I want to ask
how about charging this battery at pararel but, still, use you diagram to charge it
hmm when come in discharge, use another BMS for higher load discharge rate
would it work???
After connecting a 3Amp, 2 series BMS circuit to 2 Li- batteries in series , now when checked with multimeter for connectivity check between B+ and B- points in BMS, surprisingly, the multimeter buzzer beeps . Why B+ and B- are shorted when I connect the 2s li-batteries in series with BMS??
Very Good Video.👍
Bravo Sorin
Faci o treaba buna
Mai postează și pe canalul de mecanica
*~Keep up the good work!~*
damn, am si uitat de vechiul meu canal :))))))))))))))))))))))))))))))))))))
I made one with 7 x TP4056 and with SMPS x7... seem to work, avoid short cct or reverse battery, they can get damaged.
Good job
Great video
Good work
It would be great if you could design the protect short circuit and add it.
Some people may also put the battery in upside down.
How do you balancing parallel battery?
Sorin, you are not just any geek, you are a genius geek. Not many folks know how to unwind and wind transformers in my area.
I would love for you to tackle a solar lighting project using 18650's. I use them for lighting in the yard, but I have others working as power failure lights inside. I'd like to see your geek approach. :) I am still working on getting the right combination of motion sensor, for the interior lights, and regulating the on time to my liking. Can you help with this?
hi. in the summer I will make one or more videos with small solar panels.
We are on follow Sorin. very nice projects
I like ur precision tool
Good job!!!
Buna seara!
Enjoy your videos.
A question: working with perfboard, where do you prefer to solder the jumper wires, on top of the board or underside?
Hi. I prefer to solder the wires through the back of the board. but depending on the position of the perfboard they can also be soldered on the top.
Hello Sir thank a lot for your videos that very helpfull . I have a lot of questions for my futur project . Can i Do the same project with this module XL4015 in serie with multi isolated ac dc power supply .
1) i have a drone 3s 5200 mAh 100c battery to charge what would be Current Amp to balance 1 cell safely.
Pretty neato!!
According to the Datasheet of the dw01a Protectionchip, that is on the 4056 Board, there is a short circiut Protection. Dont know why it isnt workt in your case.
0:53 Inca imi pare rau ca al meu a luat foc :(. Super proiect, nu stiam de asta
what is the extra resistor you put on the board ? and what is it function and value ?
hi. I replaced the programmable resistor on the charging board with a 2.2Kohm resistor, to decrease the charging current to 545mA
very good video bro... thx
Ive been thinking about these for a solar charging configuration with some salvaged 18 volt panels i found at work. Think they would work in such a way or would the panels not have enough current for it?
these modules are not good for solar charging. for a cheap low power solution you can use a step down converter with current limiting and a BMS protection board for a battery pack
Primu', Sorin.
Good video
Hi Sorin, I'm teaching my kids about electronics and we love all your videos, you give great details on everything.
Question: what software are you using to create your schematics?
thanks. I use microsoft word to make the schematics. I know it's not made for this, but I think it looks good on the video.
Thank you
Do upload a video about PAM8404 mini amplifire with speaker details ?
Hi, can make a video of salvage a laptop bms, if its working fine.. how to find +ve -ve terminal for battery and power
I love your precision tool😂😂😂😂😂
Bu modülleri seri bağlayarak kullandığınızda, pillerden biri bittiğinde modül içerisindeki elemanlardan biri çok ısınarak yanıyor.
tahmini açıklamam ise çıkışı kontrol eden mosfet sürekli kapanıp açıldığı için üzerinden geçen akım ile mosfet'in direnci arttığı için ısınıp yanması.
Enjoyed your video. Do you know of another way to electrically isolate the power? I wanted to use a solar panel to charge a 4 battery bank. I need 9v though to run a device. Thanks for the help
hi. you can use DC-DC isolator converters, but they are very inefficient, I don't recommend it. I would prefer a 18V (or higher) solar panel, or more in parallel. a MPPT controller or a step down converter with current limiting (this is less efficient). a 4S battery pack with balance charging. and finally another step down converter for your load.
Excellent, bravo Sorin.
Its possible to connect tp4056 input voltage in series single supply 16.8v??
no
Can you do or review a contactless thermometer
Great video, great job! You have a fantastic channel! I have a question for builds like this, with 18650 cells. Most charging chip-sets (tp4056, dw01 etc) will charge the cell at 4.2V (which is the top limit according to the cell's specs) and some even more (4.25 or even 4.30) putting a very high strain on the cell.. since the charging chip's parameters cannot be changed, if i wanted to finish the charge cycle at 4.15V just to feel safer, if i put a resistor between one side of the cell and the charging board, would that make it stop the charging at lower voltages than 4.2V..?
And the same for discharge.. is there a way to increase the lower cut off voltage to 2.7 or even higher so that the cells don't get so stressed? I don't care if I loose some of their capacity.. just want to feel a bit safer for their parameters...
hi. I don't think it will work with resistors. resistors will decrease the current. if you connect a resistor in series with the cell and charge it, the charging current will be lower. and near the end of the charging cycle, the charging current will be very low, so the difference of voltage before and after the resistor will be very small. it will charge the cell with a lower current longer time, until the cell voltage is 4.2V. and for the discharge cycle I don't think the protection IC will read correctly the voltage and current, so it may not work correctly. if you want to power you project with 1 cell, there must be other solutions. for example you can use this module for over-discharge protection:
www.aliexpress.com/item/32788948905.html?spm=a2g0o.productlist.0.0.266c7eee3jze8x&algo_pvid=acf82334-569f-4c28-b4ae-57b0187fa6dd&algo_expid=acf82334-569f-4c28-b4ae-57b0187fa6dd-36&btsid=0ab6f81615901736350356638e1753&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
Over discharge voltage:2.54±0.1V it's not a big difference, but it is a little better than TP4056. or if you need 5V for your project I recommend this module:
www.aliexpress.com/item/32885492747.html?spm=a2g0s.9042311.0.0.27424c4dr4JFVo
it charges the cell to exactly 4.2V and it has over-discharge protection at 2.9 - 3.0V. I made a review of it and I will post it on my Patreon page soon.
@@Sorin_DIY you are amazing! Thank you for your quick and detailed reply! I will have a look on the products you suggested! Thank you!
هل من الممكن ان نسحب تيارا كهربائيا من بطاريه وفي نفس الوقت نعطيها تيارا شاحنا ؟
وكيف ممكن تطبيق هذه الداره بصوره عمليه ؟
شكرا
Good info...
Can I use those moduoles and a BMS at the same time, I mean using modules for charging and a bms for short circout and overdischarge?
yes
@@Sorin_DIY Thanks :D finally I can build a big battery pack without worrying abaut burning my house down. Your video helped me a lot, same as previous videos!
my question is, what if i charge lifepo4 3.2V on TP4056? does the module recognize the battery with 3.2V?
no. it will damage the battery.
i have done same thing like you but i never used transformer. i connect each bms to different phone charger.for 4 tp4056 you need 4 separate phone chargers.
Nice and much appreciated....but a question here why haven't you mention that you are showing two different board in different schematic.....????? asking because its confusing and will not work if picked wrong board
hi. you are right. in one of the schematics I use the charging modules without over-discharge protection. I forgot to mention that.
How did u make ur iron ? plz upload video .
hi. my soldering gun it's not home made. it's a romanian soldering gun from the '80s.
Almost a year, can you tell me please....
I want to make the battery pack separated and the charger separated.
.... Just like 7:27, I will only connect the battery pack to the charger when its drained. In this case, can i use a BMS with the battery pack?
I want to use the battery separately with bms for extra protection, and i want to charge the whole pack (through the bms) by the charger.
Is it possible??? Please answer 😢.
yes. it's better to connect the battery pack to a BMS board for protection. and you can charge it with TP4056 modules.
@@Sorin_DIY thank you so much!,😁love for you from Bangladesh 🇧🇩
hi. after disconnecting my laptop charger my batter dies in 5-7 minutes. so i remowed my laptops batteries when i checked them it varies 3,82 - 3,83 3,84 - 4,07 so i charged with tp4056 so i have some question
1- how long should i charge them
2 how can i understand they are charged fully
3 after a 10 15 minutes charging some of my batteries decreased 4,07 to 4,02 even they are free (not charged or used)
is that normal?
4 what can i do apart from those techniques ( by the way i am not experienced of electricity i just watch videos :)
thanks from now on
hi. first you should fully charge the battery connected to the laptop, with the laptop turned off. check the voltage of each cell. if it's not close to 4.2V, the cells are probably very used. you can try to charge them with the TP4056 charging module. this module stops the charging automatically when the charging is complete and the green/blue LED turns on. then try the battery in the laptop again, but most likely the cells are very used and there is nothing you can do with them. the best way is to test the capacity of each cell with a good charger, so you will know if there is any capacity left in them.
Get yourself some Polyester Tape to use instead of the masking tape.
It's the yellow tape used in switch mode power supplies, comes in different widths, and is cheap.
Using masking tape is just a bad idea, it comes loose after a while as the glue gives up.
Agreed, masking tape is a poor choice, transformers can get quite warm. Kapton tape would be best, but it is more expensive, of course.
The TP4056 protection circuit board you used has short circuit protection
What solering iron is that? or what is that type of soldering iron called?
it's a very powerful Romanian made soldering gun. it was produced in the '80 and '90, it's not made anymore.

Hi! Have you thought about using DC-DC Isolator instead of a big transformer ? Like B0505S (Max 1W out) or more powerfull?
hi. isolated converters will work, but they are not efficient or powerful. for 1W you can charge the cell with maximum 0.2A. so you need to modify the programmable resistor on the TP4056 module to always charge with max 0.2A, which will take a lot of time for big capacity cells. for these isolated converters you always need to have a load connected of minimum 20mA and max
200mA, otherwise they will burn. other disadvantage is that they usually get hot when used. you can find isolated converters a bit more powerful, of 2W, but they suffer from similar disadvantages.
@@Sorin_DIY Thanks for the answer! Appart B0505S, better spec DC-DC Isolator are expensive!
Really you are awesome bro.. 👍 👍 👍
