simple clean build, you put most of those Ive seen to shame, I especially like how you started soldering little bits of wire for the positive then realised how much quicker it would be to strip the wire a bit more and crimp it to make it stick out and just solder that, I like your style :)
Awesome skills there with the clip holding that wire while soldering. Plus that amazing wire-stripper. Wow. I just now saw how he stripped back the wire like 1/4", and then folded the wire in the middle of the stripped part, twisted it to make a tiny wire going to the connector. Forget the project. This video is about electronics skills. This guy's got em. Subscribed.
Thank you for the idea. I'm ordering the parts. I have the 12 battery holders, 12 TP4056 charging modules with protection, and I ordered a 5 VDC 20 Amp power supply. Thank you, Great project and excellent craftsmanship.
Not long ago I started playing with Li-Ion batteries from Dell packs just like the one you disassembled here. Most people don't know that a laptop battery pack can be "dead" when only one or two cells in it are "dead". I like your methodology of verifying and sorting the cells by remaining capacity and will get myself one of those charger/discharger devices. Thanks.
Brilliant simple and useful! At home you can use an old AT or ATX power supply from a scrapped computer. It gives 20A or more at 5V. However, for 1-3 (or even 4, if it gives 4 Amps) cells you can use your laptop power supply with a single step-down buck converter, such as XL6009. This will make the whole charger pocket-portable.Your way of charging Li- batteriues is the best - they have to be charged 1 by 1, not together in series. Regarding the application - you can replace outworn batteries of old wireless tools (14.4V) with only 4 Li- batteries, placed in two double 18650 holders (glued back to back). However, use protected batteries or make/use a protection circuit to avoid over discharge. Thank you for sharing!
+Bolgartopper hi... i tried and failed at my version of this. i think the problem was i was trying to charge 5 batteries at once, connected to a cheap 1 batt module as the charge controller. Im going to try this one... So do you think charging them individually is best?
that's a really neat design. I have alternate versions of the same charging board, the only difference is the LED placement and instead of a green LED, full battery is indicated by a blue LED. I use the boards to charge 3.7V single cell LiPos, and it works great.
I have found that foam board is pretty useful for mounting small projects like this. You can buy it in big A3 size sheets from Amazon very cheaply. It is easy to work with, just cut it to size with a craft knife and you're done.
I AM DEPRESSED...I mean ..impressed --------very very impressive work. THE WHOLE BUILD. BUT THE SOLDERING IS SOMETHING ELSE. ONE DAY I MAY COME CLOSE I hope
Do you know how to make or where I could buy a dc to DC boost buck converter to easily allow the use of lithium batteries in place of lead acid batteries for projects etc so that you can still get max capacity from the lithium batteries by using their full useable voltage range? Thanks.
Very good, now lets say I want to charge one of those 18650 batteries with solar panels : which solar panels would I need : voltage amperage etc and how many panels ?
Excellent video! I don't trust my wire stripping and soldering skills to be able to do something like this, though the video shows the process very clearly!
01.how many of those batteries can we charge with single module? 02. I have old Nokia 300ma batteries...like 20 of them, can I make a working battery bank with it.?
Just came across your beautiful craftsmanship & innovative use of readily available parts in a nice compact package. I'm curious if this is still working today?
great project but thanks also for showing the soldering skills. Nicely done using one wire each for positive and ground across 5 boards. others may know this but for me it was a revelation.
Hi, Thx for the clear video highlighting some practical details. I'm currently developing a project trying to power Lipo - 3S (12 VDC) from TP4056 harvesting the power from a 6V solar panel but at the discharge phase I need 12VDC: the process is managed by an MCU (ESP8266).Do you think is technically feasible to charge each Lipo individually from TP4056 @4.2V and then disconnect the parallel wiring and connect them in series by means of MOSFETs? the process would be managed by ESP8266, providing HIGH/LOW signals to the gates of MOSFETs.
Good Morning! Very nice your video, I will use 3 batteries, and I will do exactly like you, now just take me a doubt, how do I power my amplifier? in the same charging connection? Another question, can I charge using the amplifier normally?
So the parts cost 5$. What do the cheap 6$ chargers on ebay (already pre-assembled) have inside them? Is this better or is it the same part? Thanks in advance!
Could you please tell me why the batteries separation by Volts? 3V, 3,2V, .. Is it necessary separates batteries with different voltages? Why? Thanks...
Hello Well Done Tips, so there's obviously no need for isolated (floating) power supplies for each board as seen in some videos and forums? Will this charging method work permanently? Thanks in advance and good video!
Is 5v Power Supply's Current is enough to charge full all 4 batteries within the optimal time period? I think it would take a lot of time to charge all battery
+airul aszyudhi depends on how fast you want to charge. See how many amps the TP module can take. And match that. It would work, but most likely charge very slow.
Nice and easy work. I want to do that. I purchased 10 x TP4056 madules from aliexpress and they were taking 1-2 hours at the begining and now even after 12 hours they are not completing charging.When I put those batteries to my smart charger i see they wer 80-90% only charged after that long time. Can you give me the link where you purchased your TP4056 Charger Module and please give a clear picture of the board for me to identify correct before ordering. Thx.
Nice Video, can you help me with one question... I want to do a power bank serializing the voltage, so 4x3.7v, Can I serialize the output from those TP4056 to have a combined output of 14,8 like I would have serializing he batteries ? thank you!
nice work i have 4x 18560 battery pack connected in parallel with total 4.2v/2200mah how can i charge this battery pack not individually like you did as it is reside in robot and i need to just put an adapter in the robot to charge it rather than extract the batteries and charging them out of the robot thanks
Very Informative....I like how the individual batteries are charged using a dedicated circuit. My question is this, since you wired the inputs of each board in parallel would you be able to utilize a micro USB (Phone) charger ? Thank you
Love that trick you did with the cable, very clever. Would it be possible to connect the output of the batteries together if you put a diode on each cell to prevent current flowing back? What I would like to achieve is a super high capacity set of parallel cells that can be charged individually.
Awesome! Thanks for sharing! one question though, if may I ask? HOW many modules and batteries I can charge at the same time from the same power supply "like the one you use" simultaneously? Thanks again!
thanks for asking Fahad Al-Monaya I have assembled a 100 cell charger unit using the same charging units as here my only problem is that these PC boards do not seam to shut off even if left for hours I have installed 1 120 amp 5 volt dc power supply Mean Well HRPG-600-5 AC/DC AC/DC Power Supply Single-OUT 5V 120A it handles these cells quite easily.
Will this method work on two li-poly battery too? I wanna use two seperate batt, 1 for amp and 1 for bluetooth module for my DIY project but I wanna use only 1 micro usb port for charging.
Hi, cant we connect all 5 batteries to a single TP4056 module and let it charge. This could be a nonsense question as I dont know even the basics, but now a days i have some interest, and hence watching these videos from youtube. Please help me in clearing the is doubt
Be careful when using an ATX power supply like that. It is recommended to put some load on the 12V rail, if you don't, depending on the quality of the power supply, the following things may happen: - the 5V rail is very unstable - the 5V rail doesn't work at all - the power supply breaks after some usage.
Nice job. What about using tp4056 with charge and discharge function, connecting parallel batteries to a boost converter and raising the voltage upto 12v? such parallel setup can deliver 12v (upto 8A) power and it is balanced, each cell is equally charging and discharging. or am I missing something?
Excellent video! Please tell me what brand is your wire stripper? I can't find it in my google search, they look like they work awesome. Thanks for some info on them, Steve
Could I use this or something like this to make a DIY lithium smart battery for a solar array? If each 18650 gets their own mini charger it might simplify a lot. But can I just connect the power output of these chargers to draw current from the batteries? Is this a smart charging circuit that stops charging / starts charging depending on use?
If you add a bms with usb port to this device can we use it as powerbank? I think we must add that bms with paralel connection so that it should not give a voltage bigger than an one battary's voltage to the phone, am I right??
Nice! Great video..how many of these modules can I use with one power source? And how many volts does it need to be? Also, did you connect everything in parallel, besides the two power leads? Thanks
since you are charging those 5 cell using one source does the current goes equal and charge get full easily ? and in time ? and does tp4056 having a battery protection in it? please replay thanks
I would recommend mounting them on aluminium, because with 1 amp output IC is getting quite hot and lower output current, at least it was the case with my modules
Here I was thinking, I could get away with using a single module per battery pack(4 cells). Is it absolutely necessary to use module/cell or is this done to speed up charging since each module max 1000mA /Cell. Love the build quality of the pack
Hola, queria saber hasta cuantas baterías en paralelo soporta este dispositivo. Saludos Hello, I wanted to know how many batteries in parallel supported by the device. Cheers
can you also have the batteries wired in series at the same time to create a battery bank and yet still be able to charge them using a standard 5v phone charger? for example.. 3x 18650 batteries to create a 11.2-12.6v battery bank. yet charge using a 5v 3A charger?
Hi. Excellent video. Very nice and to the point. I got a 5 cell lithium ion batteries connected in series, giving me a lot of amperage at 3.7 volts. This device requires to be charged and uncharged many times like a mobile device, but works on 3.3 volts. What do I need to modify to your circuit to allow this mode of operation?
well, nothing. maybe a step-down converter to Limit your Voltage. 3.7V batteries contain +-4.3 when fully Charged, which isn't harmful by the way! 3.7V is just an average, it kinda floats around during the process of discharge
Hello sir, first of all GREAT PROJECT. May I ask you how much current is needed in order to charge 6 batteries simultaneously, using those charging boards? Thanks in advance for any answer
Is there any board for charge and protect several batteries in parallel (e.g. 5) with more than 2A?? Or are there any better options with charge over Dc-Dc-converter + protectionboards for each Battery?
is this like a battery pararrel system? each battery get 5volt and 1A or 1volt 1A? or 4.2 volt and 5A for all 5 battery? pls help me sir, i will make this charger with the new tp4056, i like your project, so interesting!! pls answer, thanks before.
add 5x "usb-doctor" module (3$ each) then you have a display which shows charged capacity + charging time + charging current. i did the same, by the way TP4056 is an awesome chip and costs with pcb only 35-50 cents
I like this set up. I'm planning to build something that would require 3-4 micro USBs to provide primary, /w emergency power if needed, for 3-4 items. Question 1) can this battery pack be charged at 12v while still providing power to the micro USB? I'm thinking that the battery pack is inconstantly being charged, while the separate modules are actively powering something.
When you charged with a computer SMPS, wasn't the ampere( e.g., 'i' from the SMPS) divided as "i/5" and went into each of the lithium circuit. Please let know what is the max. ampere in an SMPS that outputs 5V. And what is the maximum and minimum current "i" allowed through each TP4056. Anticipating your answer at the earliest.
Cracking vid, and very neat. like the link to Julians video which he explains very well. Just doing some math for people it maybe worth to do this you need at least a 5amp supply or higher (1amp per cell) for any newbeies. You get a thumbs up from me.
I've done a similar setup: just 2 modules and 2 battery holders powered by a phone power charger rated for +2A. I'm concerning about the hot that the modules producing, I can't even touch the module ad batteries start becoming gradually warm. Dunno, is it all normal? Don't want to start a fire in house or lose 2 fingers for an explosion :D
Thank you very much for not having loud music in the background... :)

Really good! What about 10 cells? Will you connect the rest of them the same way and supply the 5V?
nice video thanks, when using your pc power supply what is the max number of batteries you can charge off it??
Be careful when using an ATX power supply like that. It is recommended to put some load on the 12V rail, if you don't, depending on the quality of the power supply, the following things may happen:
- the 5V rail is very unstable
- the 5V rail doesn't work at all

I think they can charge a 18650 pack
And, dont need to install pcb or bms....

add 5x "usb-doctor" module (3$ each) then you have a display which shows charged capacity + charging time + charging current. i did the same, by the way TP4056 is an awesome chip and costs with pcb only 35-50 cents
could all together be connected via USB and charge? (im sure it would be slower, but would it be ok for li ion cells?)
Hey can I use a step up / step down ,,,power converter ? too charge the batteries With the TP4056
That was a great tips for DIY,
Thanks it inspired me to built one.
I wonder if batteries are wired in parallel, can we juste pu one module to supply two batteries instead of using one module per battery ?
can i charge the batteries with multiple tp4056
even if they are arranged in series so i dont have to take em off the pack?
Thank you for the commentary. I just subscribed and look forward to many more videos!

very good idea.its very powerfull charger.i think its impossible to find the same power amperage charger for 4x or 5x batteries.
When you charged with a computer SMPS, wasn't the ampere( e.g., 'i' from the SMPS) divided as "i/5" and went into each of the lithium circuit. Please let know what is the max. ampere in an SMPS that outputs 5V. And what is the maximum and minimum current "i" allowed through each TP4056. Anticipating your answer at the earliest.
Cracking vid, and very neat. like the link to Julians video which he explains very well. Just doing some math for people it maybe worth to do this you need at least a 5amp supply or higher (1amp per cell) for any newbeies. You get a thumbs up from me.
Cool, now how do I use the 5 battery’s (21volts) in series to power a project but leave
connected to chargers to auto balance when needed ?
I've done a similar setup: just 2 modules and 2 battery holders powered by a phone power charger rated for +2A. I'm concerning about the hot that the modules producing, I can't even touch the module ad batteries start becoming gradually warm. Dunno, is it all normal? Don't want to start a fire in house or lose 2 fingers for an explosion :D
Shall i connect 2 battery in parallel and charge using tp4056 module.. It is possible or not. Any problem occur in battery or not
