Dude...i didn't even think about how a circuit board actually worked because I never really needed to know. If someone told me they would pay me a million dollars to build one from scratch and gave me a full day to do it I would've still been scrappinng cans and eating ramen the next day...but its so simple and makes so much sense now that I've seen you do it. I'll still never do it myself, but the knowledge is cool. Thanks for that
nice "old school" workmanship & clearly explained for everyone, very well done
I am so glad you didn't show the soldering of each connection! After the 1st one or two we get the idea. Good work! Very informative!
I really liked the simplified (old school) prototyping with the copper clad board and the paint trick!!!! Since I guess am am one of the few people without a laser printer I had all but given up making my own simple boards : ( but now you have opened my eyes to how simple it really is thank you! ; )
GOOd
Thank you for your video. I have all of the batteries that I need but was unsure how to do a simple charge board. I am 75 years old and this is new to me. I have about four old cordless drills that I can now reuse with the 18650 cells and your charge board. This will keep me busy for a while. I just subscribed. Mike
Thanks for subscribing, Mike! I will soon make another 18650 cell charger video with voltmeter and other features included. I will also convert my cordless power drill to li-ion...
You can buy a 6 battery empty case with built in charger, 5V booster and USB ports for $2 shipped on ebay. No need to turn this into a big project. See my video.
You HAVE no videos... WTH !!!
Just scored some 18650 batteries and was looking for a way to charge them, thank you for a great project with lots of helpful information.
Felicitari Sorin. Ne esti de mare ajutor. Frumos, explicit, concret, de la inceput pana la sfarsit. Multumesc pentru prezentare si explicatii.
Very informative. Practical DIY. Clear instructions. Thank you 😃👍
Nicely done.
It's good to see a young guy who is willing to do things "old school".
yeah!! took me 30 years ago!! :D
is he using conductive paint?
no, he is using iron perchlorate that is copper corrossive and the pen he is using is able to protect only where needs, then what is above the pen ink will be preserved after the processes is done.
what is the pen? Paint?
I have the ferric chloride and single sided plates.
actually a pen. a CD writer pencil alike.
You are a GENIUS..!! Thank you very much.. Very simple and clear explanation even for someone who has never done something like this before, like me :) I've been working with software stuffs most of the time and I am trying to learn something about hardware stuffs like this one..
Great explanation Sir Sorin!
Thank you for this!
The best tutorial ever!
The Best Explain for me in CZcams!
Nice video, very detailed and beautiful song to follow and DIY!
Very nice, exactly the info I needed.
Smart,easy&cheap idea thanx!
Very informative video, keep up! :D
Hi Sorin ,I also have some 31685 tried to fix it with the charger but it,s not charging at all ,what is the problem . ..can any one advice me about this problem
Thank you for the simple and awesome DIY you helped me make my own charger
A very good project and very helpful.. thanks a lot
Also the tools you use are very motivating.. its looks not very expensive and so i may can afore it too :)
Excellent and easy to follow your instructions. Thanks so much
The best video.....now my doubts are all cleared..thank you sir
Very well done! I learned a lot from your video! Thank you!
Dear Sorin, I am really grateful for your efforts. You deserve the better place in this area. I would like to see a DIY intelligent charger like the Opus from you.
Well done, perfect if no green wall. Thank you! Good music too!
You came here expecting pretty walls and good music? Or learn how to make some shit that you didn't know...
I did something very similar with the same charging component.
Thank you for the video.
Great job.
Highly recomened video and a great tutorial for newbies .
Thanks man! Very informative :)
Nice,very good tutorial. I subscribed God bless you !
Thank you so much,good project
Awesome man! Super easy and very cheap.
Thank you my friend, very well done !!
Dude, I really like your videos and the way that you mention the cost of equipement👌
Thanks so much for this video!
it will help students understand what battery 18650 battery charge work， nice hand-on ability ！！
Salut , imi place imbinarea dintre "old school" si tehnica moderna ... bravo pentru video, continua
Great tutorial! Everything is well explained, thanks!
Very impressive thank you for posting.
How can I charge it if I have the batteries wired in Parallel?
Very Nice - Good Job!
Some people complain but I love the music!
This is awesome, thank you.
Danm what a beautiful basin so clean
Thanks! Nice narration.
If you made it in a parallel instead of a series would it take longer to charge??
Great Stuff, whats the calculation to match a good power supply to the charger/batteries ?
7:05 GENIUS!
Foarte bine explicat ! Bravo.
Thank you for your video.Nice video !and good project
If I set a power supply with constant voltage and current control at 4.15 volts 1 amp , will that work safely? Thanks nice work
Amazing video. Proper stuff
Hi I would like to know if I can put 3 18560 batteries in serie and charge each one with a tp405 in parallel with the batterie.
Thank you very much
You can only use multiple TP4056 modules on individual cells in a series pack when they are fully galvanically isolated from each other. Otherwise the shared common ground between the modules and batteries will short your cells.
Cu clipul asta mi-ai reinviat dorinta de a ma reapuca de montaje ca in anii de liceu.
Thanks for such wonderful videos!! I copied this design, tried charging similar make 18650 cells using a 2Amp, 5v charger. I do not see the charging stops even after the cell reaches 4.20 volts. But when I try to charge the same cell in a single TP4056 module, it finds the cell to be at max capacity and stops charging. I am confused what could be the issue. Anyone faced similar issues? Thanks.
Hi, in this case you charge the batteries in independent form, in parallel connection of circuit charger but if I want charge a batteries array 2P3S as laptops battery, then is serial connection among chargers circuit. Moreover, adjust the current in mA. Kind Regards.
Great video, very helpful
Keep it up
Hi Sorin, Would this charging setup work if TP4056 were connected in series rather than parallel if I wanted higher voltage output?
Thanks
hi. it will not work, because all the charging modules have the same power source. for 4 cells it will work only if each tp4056 module have its own power source and each tp4056 module is connected individually to one 18650 cell. finally the cells can be connected in series. this will be a 4S with balance charging. I will make a video soon about this type of charging.
Thank You
I would like to see some information about that as well
Sorin - DIY Electrical Nerd Looking forward to a detailed video about properly charging 18650 cells in series, with balancing and protection etc... I am building a bluetooth speaker that requires 24v and finding good information about charging seems dificult.
Do you ever add a resistor to VCC IN to help with heat? Mostly for charging at 500ma-1A
I didn't add a resistor to the power input. if you charge the cells with 1A, the TP4056 IC will get hot. you can add a heatsink on the IC. or you can charge the programmable charging resistor, so the module can charge with a lower current, like 700 mA, this way it will not get hot.
Can this charging method be applied to 3S 18650 system using the TP4056 module , and have a secondary wiring for the batteries to provide 12v output isolated by a 3way on/off0n switch ?
The 3S modules are not very good , I like the TP 4056 better .
no. I made another video on how to charge li-ion cells in series with TP4056 modules.
@Sorin - DIY Electrical Nerd - what controller would you recommend for 2S3P (so 8,4V out) 18650 pack?
hi. there are a lot of 2s protection boards, but you should use one with balance charging. I suggest this one, I haven't try it, but I think it's good enough:
www.banggood.com/DC-9V-4A-2S-Lithium-Battery-Protection-Board-Li-ion-Cell-With-Balanced-Charging-p-1163824.html?rmmds=search&stayold=1&cur_warehouse=CN
Hi Sorin , I have some old laptop battery that is flat ,Power shows 0 v . To revive this battery i have seen some clips in you tube how to clik back the battery breaker top part for live again ,from your experince is it save to revive the battery as per video clips
your advice please ... tks
hi. you can revive li-ion cells, if they are not damaged, just overdischarged. but I've never tried to charge batteries which have less than 1 volt. you can try it, but you have to monitor the entire process. you need to start with very low current, I would say about 100 mah / cell. if they start to get hot, they are not good anymore. after a few hours the cells should reach 2.4V. now you can increase the current, or use a standard battery charger. after the cells are fully charged, you leave them for a few days. then test them with a multimeter. if the cells have more than 4 volts, they are still usable.
Hi Sorin ,thanks for your swift reply, Good info , I just received some similar info about how to go thru the whole process of chargeing , but not as more details as yours , Thanks Pal , Waiting for my TP4056 board once received i will fixed it the way you thought me ,,, Tks will contact you for more advice if needed ..
I have done something very similar with a vero board but woithout the plywood base. I have used plastic screws as "legs" for the charger to stay 10mm from the ground and also used 2 x 40mm fans to keep the TP4056s cool while charging. I am using 2 step down converters and a laptop charger to step the voltage down to 6V and feed that to the charger. This can charge the cells with 1.1A each very easily but the fans are needed as each TP4056 is dissipatinf anywhere between 2 and 1 W.
You need to keep the cable lengths and connections minimal as it reduces the charging current.
Good thing I am subscribed with this bad boy
Bro this was amazing
Great just what I needed for my project it would have nice put a picture of the wiring diagram.
hello good job
the wire that replaces the pin connectors, is it really 0.8mm²?
because it fits easily into the holes of the card, it looks like 0.5mm²
the wires are 0.8mm. the holes are not perfect.
So you poured the ferric chloride that dissolved the copper from your board down the drain where there are copper pipes?
Actually most european pires are pvc anyways :P
(but good point x had a laught at the thought)
Good job... keep up the good work.
These are great skills needed for the future!!!!
Love this tutorial！
Great job mate. 👍
Hello! If I use a single 4056 to charge two cells in parallel is that ok? O I do something terrible wrong?
hi. yes you can charge 2 cells in parallel, but they need to be the same model with the same capacity and be discharged to the same level (same voltage). and you will use them still connected in parallel.
im planning on doing this myself just adding a battery indicator display, i have some 1.5mm cable in my garage would i be ok using that for a project this small?
hi. the 1.5mm wire is very good for this project.
Will plugging in a usb charger to two of the micro-usb ports speed up the charging for the batteries?
no. the microUSB ports are already connected in parallel. you need a powerful charger.
Just made one of these. the blue leds come on when I insert the cells BUT I noticed the larger 6 legged chip gets very hot on both boards. Is this ok? are connection +/_ are correct. Power supply was a old camera charger 5v 1.5 a
hi. the IC is getting hot, when it's charging with 1A. so for bigger capacity cells it will take longer to charge them and the IC will get hotter. if you charge big capacity cells (bigger than 2Ah) I suggest you add a small heatsink on the integrated circuit.
@@Sorin_DIY Hi Sorin, I have an issue, for me the TP4056 module has a blue and a red LEDs - when plug the microUSB connector both stays on, also the protection is not cutting off the charging current - it climbs up to 4.25 where I cut it off manually (disconnected). I think this is not normar right? if yes, how can I debug it - what is wrong?
Can you make a video on how you made your soldering iron.
Hello, nice video! One question... Does the OUT+ port always provide 5 Volts when:
1. The battery is full but the power source still being connected
2. The battery is currently chargin
3. The battery is powering the device on the OUT+ port
hi. I suppose you are referring to the TP4056 module with battery protection. the charging module can provide max 4.2V for the battery. the output voltage is the battery voltage.
1. when the battery is fully charged to 4.2V, the charging module doesn't provide voltage anymore, but is still monitoring the battery voltage. if you have a consumer connected to the battery and the battery voltage slowly drops to 4.0V, the charging process starts automatically and the charging module is providing 4.2V again.
2. & 3. the out pins deliver the battery voltage, even when the battery is charging.
thank you! :3
I need charging circuit bord with USB and charging port and how much rupees ?
great video :D
I want to build a LED lamp with these batteries and charger, can I have the LED's turned on while charging??
it will work, but it's not a good idea to use the batteries while you charge them. it will shorten the batteries lifespan.
Very nice "How To"!! Can you use all 4 TP4056 together to charge with 1A each? Thanks
Can you use 1 charger for earch tp4056 module? Example you have 4 you will use 4 cabes and charger will that work? To charge the batteries individually and faster?
yes, with 4 USB chargers, each tp4056 module will receive more current (max 1 Amp is needed ) and the cells will be charged faster. but if you have one single USB power source with 4 amps, it will charge the same way.
Sorin - DIY Electrical Nerd thankyou im going to make one too!
SALUT.
Nu am inteles cum le incarci oe toate odata cu un incarcatot de tel sa sounem?
Imi poti explica cum ?
Multumesc.
salut. intrarile tuturor modulelor sunt conectate in paralel. deci daca pui cablul microUSB la unul din module, sunt alimentate toate.
great video, nice work, and what a cute cat!
What if i use a more powerful charger but only input one cell will it take all the current or the module limit it to a maximum ?
It's limited to 1A.
Sorin, would you be able to avoid using the black wires if you had more room on the copper plate to lay negative traces underneath? Also how did you wire up that volt meter to make it work with usb?
hi. if the copper plate is a few millimeters longer, you have room to lay the negative traces and not use the black wires.for the volt/ammeter you can find a diagram in the description of my power supply conversion videos 1 & 2.
Thanks. Very good video.👍🏼
At the end of the video you said that if you want you can connect a higher Amp charger if you want a faster charge. What's the max Amp the TP4056 can take?
each tp4056 module needs 1A for the fastest charging time. so for 4 charging modules you need at least 4 Amps. if the supply current has more than 4 amps, for example if you connect the tp4056 modules to a PC power supply 5V output, it still uses the maximum 4A with no problem, even if the PSU 5V rail has 20A.
Assuming your USB cable can handle 4Amps. The most expensive cables tend to only go to 2.1A
I recommend making your own cables in this case and not using the USB plug at all
Imperf3kt Sweet, thanks guys.
how fast does it charge with the new Quick Charge 3.0 wall chargers which can do 18watts and 12volt?
hi. qualcomm quick charge 3.0 technology (same for Samsung adaptive fast charging) works at full charging rate (9V or 12V with 1.5A) only with compatible devices like samsung S6, S7, S8 and other newer phones or tablets. these devices know this fast charging technology and negotiate the charging rate with the charger. all other devices (that doesn't know the fast charging technology) will draw only 5V at max 2A from the charger. same for this 18650 battery charger. the fastest way to charge the cells is to provide 1Amp for each tp4056 module, in my case the best USB power source should provide 5V with 4Amps.
Sorin please tell me which is faster and better, a TP4056 module or a HT3786D ic chip?
Also is there now a module or IC chip with USB type C fast charging?
I am learning which be the best to build my charger. Thanks!
Hi. I haven't tested the HT3786D IC yet. I ordered some new charging modules and I will test them in future videos. I will make a simple fast charging powerbank soon.
dude can you tell me what a function of in+ and in- hole..
hey bro.this video is great.how can we make a charger to charge a battery in which 18650 batteries are placed in series?
hi. I made a separate video about that, you can find it on my channel.
Most useful cat video ever! Thanks!
Hey man, what if I had two lithium ion batteries and I connected them in parallel, can I use just one TP4056? Or do I need two?
if you also use them in parallel, yes you can charge them in parallel. the cells need to have the same capacity and preferably the same charging/discharging cycles. if you intend to use them individually, you should charge them individually.
Helo
Can i use this module(HX-3S-FL10A)
For 6 lityom ion batteria
3 seri&3 paralel
yes, but it doesn't have balance feature.
how did you discharge? thanks (also are you able to have capacity displayed? or internal resistance someway?
hi. my next video will be with a better battery charger, with discharge capability (with protection) and voltage monitoring. it will be available in a few days.
Good video. Nice layout of the PCB. Only issue is the completely wrong way to solder. Heating the joint then applying the solder to the joint is the correct way.
I saw two other similar videos but on those it is recommended that each circuit have its own power supply. The one actually went as far as using a transformer with four taps, rectified, to supply the 5 volts for each circuit board. Could you explain why they did this and why you have not done so.
hi. if you have a battery pack with lithium cells connected in series and you want to charge it with TP4056 modules, they need to have isolated power supplies. but if the cells are not connected in series, you can use one power supply for all charging modules.
Hi Sorin. Thanks for the Video - very informative. I have hooked a couple of the new version of theses chips up using your schematics. It seems to work but the board/chip gets very, very hot. Is this supposed to happen? I have 2 x 18650 hooked up. The newer version of this chipset has a s-8205a protection IC as well and I am curious if that may be the problem.
hi. the protection IC is not the problem. the tp4056 IC is getting hot when is charging with 1Amp (3.5V - 4.1V according to its datasheet). mine are getting a bit hot too. you can add a small heatsink, like these:

Ah fantastic. Thanks for that. I have ordered some. cheers.
Well done. Impressed with the fit you achieved with common tools.. BTW, do yourself a favor and pick up a good iron, that gun is destructive.....
