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!
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!
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.
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.
Fantastic demonstration, really liked it.
I saw ur video first time and ur so informative thanks bro
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 :)
I love the comic relief and jokes. I see you have an interesting personality
Bravo Sorin cotinua tot asa 👍
asa..bate-ti joc si tu :p
Nice project and your cat too.
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.
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...
learned something new about tp4056 boards 😄😄
Very good project 👍
Good video, very informative. I'll be careful not to upset you, I don't want to get "a little busted". 1:03 LOL.
Excellent. Thanks for your help. I have subscribed to your channel.
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😞
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.
Nice project and your cat looks cute
Yuhuuuu ,felicitări!
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
You have the best precision tool
Brilliant ! We to be a good friend of this guy after the Apocalypse.....
Felicitãri, Sorine.
I made last week video about tp4056 18650 battery charger.. works amazing!
Good luck for 1M sub. Sir I guess you can get 1M soon have a nice day sir
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?
That's an impressive soldering poker
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.
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..
Super video!
Nice video, thanks :)
another good project

Great video
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 work
Bravo Sorin
Faci o treaba buna

*~Keep up the good work!~*
damn, am si uitat de vechiul meu canal :))))))))))))))))))))))))))))))))))))
Pretty neato!!
Good job!!!
Very Good Video.👍
Good job
You can use separate phone chargers and wire the cells in a series. I did it.
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.
We are on follow Sorin. very nice projects
very good video bro... thx
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.
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.
Good info...
Primu', Sorin.
Good video
I love it how you have the serious voice and make the best jokes! ;) Very informativ and entertaining! I you have nothing to do one day, please do a video on how to make a li ion charger with (or modify a TP4056 one) to charge only to 4.1v or with selectable voltage. I searched the whole internet and could not find one single guide or explanation.
could I use 3 step up boost modules to connect to the tp4056 from 5v instead?
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.
I like ur precision tool
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

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??
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.
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.
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.
Hi, can make a video of salvage a laptop bms, if its working fine.. how to find +ve -ve terminal for battery and power
Excellent, bravo Sorin.
new subcriber from malaysian. love all your joke
U r videos are awesome boss...like it ❤️
Nice channel!
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.
How do you balancing parallel battery?
Do upload a video about PAM8404 mini amplifire with speaker details ?
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.
0:53 Inca imi pare rau ca al meu a luat foc :(. Super proiect, nu stiam de asta
Really you are awesome bro.. 👍 👍 👍

Take love from India.... 👍
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
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???
The TP4056 protection circuit board you used has short circuit protection
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!

I need TP4056 for my bungholio!
LOL. Are you threatening me???
@@rpbajb Surrender your TP4056 now!
@@klaasklapsigaar1081 You may take my TP4056...but you will never take...my BUNGHOLIO !!!
Hey there, nice video, but i would change the tp4056 modules with some tp5100. Theese use step-down to regulate the charging current, so you can feed them with up to 18v, are also programmable, and won't heat up nearly as much as the tp4056. They don't have a USB port, but you're not using them here so...
those will work too. but I wanted to test TP4056 modules, because they are more popular.
@@Sorin_DIY Absolutely, i only have one TP5100 for testing, but i bought more than 20 tp4056 in total... i'll only order 5100 from now on however...
After a long time at last..
Nice
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.
Pls make more videos about Seat Leon MK1 (1M) maybe tail light repair
Great job Sorin, have you had a chance to check out my video doing the active balancer using tp4056? I made a 10s charger. So far it’s working pretty well and charges each cell using 1 amp per. It was a fun build that’s for sure!!!
hi. that will work too, but I like transformers more :)
@@Sorin_DIY That is pretty cool!!! Mine has transformers....LOL, just a whole bunch of mini 5V ones...LOL. I wasn't looking for a BMS like your build. Just a way to charge some of the 10S battery packs I'll be building. I looked everywhere for a cheap alternative and couldn't find one, so I decided I might as well build one myself. With this one, the best way to use it is to charge the pack to around 75-80% full and then plug into the active ballancer I made. It can charge the pack from 0 to full, I just found it faster to do it the other way. Love your video and your work!!
I couldn't find your video on your chanel? What is it called? Link?
14:03
I sure did ,
Thanks.
That was fun tp4056 in series :-) Is there a way to do the isolation without a transformer? For use in a solar setup? Since that is all DC we would have to make AC and than go back to dc.
hi. another option is to use DC-DC isolated converters, but they have a low efficiency so it's not recommended. you can use a solar panel and a CN3791 solar charger and a 6V/9V/12V solar panel for each lithium cell. this method will have a better efficiency, but will cost a lot. the most efficient way is to use a solar charge controller. and the cheapest way is to use a buck/boost converter and a BMS board.
@@Sorin_DIY Hi. thx for your reply. I am just fooling arround with 4 old solarpanels on my shed old batteries from where I can get them. I am using buck converters to get the voltage down. I have 2 42 volts and 2 +- 35 volts panels.
The are just stupid voltages giving me headaches.
My e-mopet has a 48 volt battery (which means it is 54 volts) and the charger can peak to 60 volts. Most you tube examples go to 30/35 volta examples max andso far I am to big a electronics noob try to change the exmaples into something that works for me. Lots of magic smoke. Today I tried to make a flyback buck converter to convert 54 volts to 12 for the electric moped. But burned loads of mosfets and 3904's Try again tomorrow :)
Next time try to make a battery tester which tells you the capacity of an older battery (like the one you have but diy) it will be hard but I think you can do it!
totusi nu-s 100% daca se poate
How can we raise the discharge cutoff to 3.0V (from 2.5v)?? It would also be nice to lower max charge from 4.2V to 4.0.. possible?
I don't think that is possible, these features are controlled by the chip. you can try to add a low value resistor between the battery positive terminal and the module. this may work for the over discharge protection, because under the load, the module will read a different voltage value than the cell really has. you can try with different resistors of a few ohms and different loads.
@@Sorin_DIY there is such a high demand for it. You would think the chip manufacturers would listen. 2.5V is stressful for these cells
Sir for your next video. Make a 12v battery pack with 18650 batteries. I am making my own ultimate powerbank.
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
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!
