I prefer to use USB type C Power delivery feature to get higher voltage for 2S/3S/4S instead of boost converter. & also TP4056 is just a general purpose IC for DIY projects. I suggest using CN3795 IC, a multi chemistry, Multi cell battery charging IC including MPPT for solar charging. In combination with normal BMS, this system can literally charge any type of battery pack with USB type C.

This is exactly the education that I need to understand projects involving high current and 18650 batteries. Thank you!

This was SO helpful. I was looking for a power system for future DIY projects!!! Thanks for this!

finally someone explained it to me. This is what I needed. Looking forward to seeing material about BMSes

Thank you for posting this, I was looking for a way to charge a 2s setup via 5 volts usb, but I couldn't find any modules. From the looks of it it's going to be a component setup. You made a new fan today, thank .

I'm so grateful for your work. Keeps me going on my projects

Just what I was looking for yesterday! Thanks for the video!

Yeah, perfect timing. I have also been searching for this type of board and saw that they don't exist. I needed a high-capacity ultra-quiet 5-volt (USB out) battery module. So I opted for a 2S-4P battery configuration with a buck-converted output. I had to piece together different circuits to meet my needs. It is very cumbersome with three switches and a battery level indicator to ensure I don't over-discharge the cells. Since I didn't include a boost converter for the charge source, I am using a 10VDC wall wart. The first switch is the charge/output switch to route my 10VDC charge source to the 2S-BMS. The second switch is used like the on/off witch. It is part of the DC input plug. When the wall wart is disconnected and the charge/output switch is in the charge position, then the batteries are isolated and it's essentially off. The third switch is a momentary switch used to activate the battery-level indicator so it will not drain the batteries. What I feel there is a need for is this and I would purchase them from you today: Fast rechargeable, high-capacity battery packs with USB output and adjustable DC sources. It would be nice to see the battery level, the output voltage, and the output current with a simple push button. The output should be a low-noise DC voltage from a linear regulator. It could be also current-regulated for the ultimate version with an optional fan for cooling. The charging voltage could be from two sources. A high-current fat charge could be from a wall-wart and a slower low-current source could be from a USB port with a boost converter to match the 2S or 3S configuration. I think if you built a board with a choice of 2S or 3S configuration options, you could sell thousands of these boards.

Thanks buddy; Will be waiting for more videos on the topic. Your channel is amazing 😮

really nice to have stumbled upon your channel. congrats on your good work!

I reckon you're on to something good here, if you can design and provide a general purpose 1-4s battery charger that offers all the usual protections (over/unders etc) combines USB C with PD input, ( with selectable outputs like the PD decoy boards) you could be the founder of the 'next' TP4056 chip for makers all over the world!🤩

Thank you for reassuring me i am not crazy. I was looking around Ebay and Aliexpress for a 2S Charger together with a BMS Circuit. Exactly like you stated, it was either a charger without protection or a BMS without charging IC. I thought I was too dumb to look for the right parts, but now I'm glad someone else has the same problems finding a suitable module.

Brilliant idea man. Good job and thank you for sharing. I will try your PCB

I'm looking forward to the bms conversation. Hoping you will also talk about bms that can and can't charge and discharge at the same time...

Wow! Love your channel! A lot of great informations!

I like the powerbank ICs from Injoinic and others these days. Probably not the best pick if you really need a lot of amps, but for general electronics they include a lot into a single ic with very few discrete components.

Can't wait for the BMS video.

Thank you!! It seems like i found another information vid for my electrical projects i make! As its mu hobby!

Thank you for the video! Will the board be usable as a charging board for a laptop-like behavior? When switching between battery charging and battery usage (and viceversa) is seamless?

I bought a 10A strip 1S BMS and then connected it to a USB-C charger module for USB PD and a protected 14 AWG 2.5 mm DC jack output on a broken 30,000mah powerbank to repair/salvage/upgrade it.

super useful, thx! 🙂 like the others i would also be interested in a chip which has all the protektion + high ampere out + using the higher voltage USB-C features

I have 38 of the Panasonic NCR18650B batteries. Awesome batteries!👍 The spec sheet says they can only discharge 15 amps "continuous" safely! I just thought I would mention it to you since you were showing a picture of this particular battery with a discharge rate of 20 to 30 A. next to it. By the way you know way more about Electronics than I ever dreamed🙂👍

Also most type C PD charger will output 5v, 9v,12v and 19v{or 20v}. With this you could use a PD type charger and avoid a boost.

Check out the 12v ups switch modules too. They are pretty cool, can switch to wall power if the battery goes under 10v. Pretty useful for a constant running Rpi server on a solar system.

How would you implement the 2-cell charger talked about at the end? Would you still have to alter the Mosfets like earlier in the video? How should the USB PCB and the bms PCB be connected and what changes should be made to implement everything onto a single PCB? Working on a project this is just what I need but I'm stumped on the implementation.

i literally had this same problem the other week. very good idea

great video, can u do a video on all the component break down of the USB booster that can charge up to 4S with 2A, thanks

Great video, just what I need.

Great stuff! Is it possible to find a bms that allows selective connection/charging for multiple batteries from 1 to 6 cells or more?

This is interesting timing as I've been working on the same thing with the same modules. So far I've been able to over together setups that work for me but the one thing I've not had any luck at is wireless charging with a QI receiver module. I found one with a USB-C connector rated at 5W that does work... sort of. Once the BMS reaches 11.79V the output from the QI drops to 2.24V and NEVER goes higher meaning the batteries never reach 12.6V cutoff. I found one QI receiver rated at 10W but I outright refuse to pay $20 fire it just to test.

10 amp output at BMS is excellent, but which boost convertor do you suggest that can output a high current at 5 volts e.g. for driving multiple servos?

As you mentioned in the video How many amps of current will change the battery by the 1s battery charger made by you... Hoping for a early reply... Thanks 😊

Really interesting video. Good information. 👌

Nice video, hope you got your boards, and some company considers your idea. Maybe make the max. output current selectable.

C'est ce que je cherchais depuis u bout de temps . Merci pour le PCB .

Can u do reviews of different types bms n what chips are they using , pros & cons of each bms, thanks

I'd love to see a video on how to convert an old battery drill to LIPO. I've seen a few video's in the past by other creators. But they never seem to do anything with output ampage or with how to charge a battery configuration that may be set up as something like a 3S2P pack.

I really like the last module with multicell usb C, it really simplified my project so that i just need to add battery level indicator and a bms, I have used this module for my 12v Portable speaker project and it work so perfect and reliable. I thing this module is kinda new or underated bcs i see not a lot of online seller have this module & not many youtuber dicuss about this module

Andrei, This was another great video. I ran into this issue a couple of months back when trying to build a battery pack for my RC car I was working on. I wanted to USB charge my 18650 Li-Ion batteries without removing them from the holders because the holders are prone to breaking with repeated removal and insertion of the batteries. I asked around on electronics groups on Facebook. They didn't have a solution. So, I came up with something that works. But it isn't as elegant as the solution you are suggesting. And your suggestion would use less parts. I already tried sharing a Google drive link to my schematics. But KZfaq removed my previous comments. So, I'll describe it here. Basically I designed and built a battery pack PCB that has one SPST main power switch and one DPDT mode select switch. Each battery can be switched from 2s in series and independent using the mode select switch. When they are independent the batteries are connected to the battery terminals of a TP4056 module (there are two modules, one for each battery). So, when I want to charge the batteries I turn off main power and then switch to independent before charging each battery using a USB cable for each. Then I disconnect the USB charger cables and switch back to 2s in series. Then I can power on my loads. To protect the batteries from deep discharge I have an ADS1115 reading the voltage of both batteries and the second battery for my ESP32. I do some math in the microcontroller to get each battery voltage independently. I then have my ESP32 programmed to let out a chirp from the RC car's buzzer and kill the outputs if the voltage of either battery drops below 3.0 Volts. I also transmit those voltages to the Android app so the user can see what the voltages. This is not as elegant as the solution you are suggesting. Do you think you might develop the 2s version of your circuit in the future? Thank you for looking into this. Another great video!

Thank you very much for your videos

A great lesson. Thank a lot

Which do you recommend for making a small battery pack to power 5v LEDs? I’m looking for a solution for LED ligh boxes. I’m thinking 4-5 18650s in parallel and a charging circuit that can output 5v.

yeah i plz i got lost choosing the bms and collecting data on the internet this would be so helpful

Great video May god bless you.

Just ordered these boards.

Btw you got a new follower ! ❤

Usb c pd can do up to 20 V 5amp and more if the cable is rated for it. You're obviously intelligent and deliberately left it out to keep it simple for none pd or pps supplies yes or? Perhaps you could recommend in another project one that fast charge and whatever rate the input can output to battery to the maximum the battery supports. This would be super useful I have a 5 or 6 or these from an old battery pack that the controller died I think and would love to repurpose them for a led torch since no led rechargeable torches fast charge that I've seen lol. Cool video though thanks.

I know it will sound dumb to most people, but it works for me. I just hate the hassle of charging every single thing with it's own USB connection...so instead, I just make all projects have a fast, easy way to swap 18650's. I just always have 18650's ready to swap...and then I can charge everything externally in a higher quality 8 bay charger. It's a lot of swapping, but for me it's easier than dealing with a cable and then waiting for it to charge. Some things I have to climb a ladder to swap, but I'd still have to plug in a cable I figure otherwise. You can also easily keep track of the internal resistance of your cells individually and pull out of rotation when they make a big jump in IR.

Good video, thank you!

Very informative 😊

USB PD can delivery upto to 20V 100W. USB PPS allow us to custom voltage and current output limit. Can you please try this method also??

I am super interested in making my own battery charger just like you showed. Currently Im using the 4s version that comes in 1-4s you show at the end but i definitely need to upgrade to include the BMS and unde rvoltage cut off. Do you have a schmatic a 4s BMS and the 4s charger? Im super busy with other parts of my project but im hoping in about 2 weeks I will beable to dedicat the time to cimbining these circuits. Any help finding these base schematics would would be very appreciated! Thanks! I look forward to the BMS video to come!

what about battery to the 3602a a mosfet between battery and load and the output of 3602a to the gate of the mosfet? that way 3602a will sense undervoltage and cut the gate?

So the only thing needs to be replaced is the MOSFET in the charging module? If so, can you please be specific what is the needed MOSFET to have the 10 Amps output? I'm working on this too, but on flex pcb

Hey, First of all thank you for your Videos. I am studying electrical engineering in Germany. How much of your knowledge did you learn in your studies and how much would you have to teach yourself? What tips do you have there? I don‘t learn much about that in my studies. And some of my professors are very bad.

Thank you👍🏼

The DW01 protection IC found on those TP4056 boards cuts off at 2.4V not 3V

Thank you 👍👍👍

Hello Sir, Can I charge 3s and 5p battery pack which is around 11.1volt &10000mAh with 8:52 chargers like this directly connected to BMS? Or do I need any other module in the middle of BMS and charger to get my battery charged? BMS----> charging module---> Charger

Thanks for the video ! I have s personal passion project I made years ago, but probably need an upgraded charger circuit. It’s s tiny handheld arcade (3d printed). It uses 3x18650 cells and I would love to make it right and upgrade the system to use the new raspberry pi 5 which uses USB c and suck more amps. Also I would like to have fast charging on it. Would that solution in the end works for my project ?

Your final module print would sell well. I'm saving this video for your gurber file. 👍🇮🇪🙏🏻

what circuit you recomand me to convert 3.7v to 1.5 or 2v with up to 4A max ? thanks

Hey why not add a current adjustment for protection, if micro electronic goes bad they may pump upto 10amp leading to fire....

Thanks dear. Alhamdulillah learned very important lessons. Allah bless you.

Nice Vedio. i got quection, i want to make power bank for external camera flash (6v) and i make one using DC-DC Buck Converter but problem is when i trigger the flasher batterys getting hot then burn the Buck converter. any suggestion please.

Very interesting! Is it possible to recover an MBS from an old laptop battery?

18650 cells can also have integrated BMS boards, they mount on top of the negative end cap replacing that connection.

Great video

Hello, Some time ago you told that you are working on a lithium battery charger discharger. Any update about that??

Great teacher 👏👏

Good idea I'm not some who leaves comments either I believe what you looking for is on Drone battery's. 4.5V USB CHARGER but the battery do have a short life. Although that depends of the class of the Drone My Typhoon Q500 4K well the battery's Are 12v It would be nice if I could change it with USB

Can you build 3S and 5S BMS with USB C PD type charger ( also with no current limit but undervoltage protection? )

if i have a project thats power supply is 12v 500ma 6w and i have a 12v 65000mah which of these options would be best?

I really want to make my own battery bank as I find the ones on amazon to have low quality cells. I am thinking of making a 4s 3p (12x 21700 cells) battery pack and want to have a few 65w USB PD connections and have it charged via USB C too. I've found a bunch of different boards on Ali express that can do these functions individually, but It seems messy and I'd love to do it with 1 PCB. However, I cannot find anyone on KZfaq talking about USB PD 3.1 or 3.0 and QC + other protocols. I can only find people making trigger boards. It would be awesome if you could make a PCB design tutorial like you did in this video, but implement everything in 1 board such as a 4s BMS + PD, etc

I’ve been trying to get a 1S but get higher voltage out of it. I have not found many devices that boost 3v up to 19v at reasonable currents to charge an laptop.

Very interesting vedio. I used Tp4056 in prallel and its works wall. it can change 1S battery pack more than 8A.

Sir I made a project.i use 4 lithium ion battery 3.7 volts in parallel.and use tp4056 circuit to charge it.the ic heated up.what can I do.

How can you charge multiple batteries in parallel? Do you need a specific BMS?

Did you ever have any made and tested ? If so will we be seeing a video?

If the batteries are charging (not feeding) where is the 5A or 10A power demand coming from? The 5v USB supply can both power the 10A project AND charge the batteries at the same time? Will a simple phone charger wall plug do this?? If your end demand is say 20v at 100W thats 5A? Is max input power 4.2V x 5A fast charge making 20W not 100W required?

Can you please explain more about how to connect 4s battery pack to type C module

did you receive the new designed PCB yet?

Why not use a 1s bms with hight current rating. Now let the b+ and b- of the tp 4056 module be connected to the p+ and p- of the 1s bms, and connect the battery to b+ and b- of the 1s bms, and take the load output from the p+ and p- of the 1s bms? If the tp4056 board is the one with the dw01, then overvoltage protection is there by both the tp4056 and the 1s bms module, while the undervoltage protection is provided with the 1s bms, and with a higher current limit too. Can be charged with standard inputs into the tp4056 ..

Panasonic NCR18650B, Max. continuous discharge current: 4.875A

why not use an IP5328P? I think it checks all the boxes you've mentioned.

Hi! I'm looking for a method that recharge typical battery nimh children games (like cars and other stuffs) that works with 2 - 3 - 4 1.2v batteries. I would recharge directly via usb that stuff without open it, take the batteries, put them into a charger and then put batteries into the stuff again. How could I do?

I was wondering why there isn't a board like this already the other day. It seems like a no brainer.

Bro help I want to charge 3 cells in perlor from 5 v and out put to small amplifier with spikers .

Hi my friends, if I could give you a hug well I would. this is the best video seen since my internship in psychiatry. I am a battery salvager who uses opus and xstar chargers....can your method charge an unlimited number of cells in a single charge please?

Any updates for BMS tutorial?

what mosfets did you use i cannot find "4804nt" mosfets anywhere

Hi can you charge 36v18650 battery on a 36v lifepo4 battery charger

Which module can i use for 18650 3 parallel

Excellent thread! Also consider using the FS312F-G to replace the DW01. (thanks to "Great Scott" on KZfaq) The DW01 over voltage threshold is 2.4V. I prefer the 2.9V threshold of the FS312F-G. Some of the batteries I build go up to 13S, yet what you are proposing is quite useful.

Make a BMS usaing your own designed PCB and make a video on it and also make a BMS FOR 12.6V BATTERY, I USED A CHINES 100A BMS FOR CHARGING OF 10A LIPO Battery and used in my Yamaha ybr 125 battery but there is a problem with that battery charged on bike 14.6v dynamo power throught rectifier but as its max voltages is 12.6v as compared to lead acid battery which has 14.4v at full charge so bike headlight is dim and horn sound is lower then lead acid battery so please find a way how could a lipo battery bank could be used and we could get out put of 14v reguards

Hii i want a C- type charging module with 5v usb output to charge 4.2v 4000 mah litium polymer battery i want to make a power bank so please can you suggest me any module for this project

Hi folks, maybe someone can help me out the purple 3.1Amps board seems to be good enough for my use case only question I have is before ordering it does the undervoltage also only happen at 2.5V instead of 2.9? Worst case I could live with that but good to know. Other question I have is when I connect this BMS pcb to the cells say 1S2P do the leds of the how full it is indicator blink all the time and worst case suck the liion pack dry? Or does it go to sleep at some point so I for example I dont use it all the way in an application put the battery to the side and it will basically keep the same charge level for example over a week etc.

Hi mind me to ask if you have sample battery to power raspberry pi

I guess that you can have some problems in case you're using your device while it's charging, depending on the amount of amps needed
