In this video I will present you my DIY LiPo Supercharger circuit, co-produced with @Elektor! If you connect a LiPo battery to it, then the circuit can charge it up with 1A of current through a USB Type-C port, it protects the battery from overcharge, over-discharge and a short circuit and it can even boost the battery voltage up to 5V or 12V with an output current of 1.5A and 0.75A respectively. This circuit is basically an improved version of my old Charge/Protect/5V Boost circuit. But this time you can even buy it as a kit! Let's get started!

Big fan of yours
2nd ?
Nice one. In the video you tell, there are Gerbers and such stuff available. I cannot find those behind the given link. Could you clarify, please?
Great Project!
Is there a way to modify this to work with LifePO4 batteries ? Ideally auto sensing the battery type ?
Where are the links to the schematics?

Even though I'm probably not gonna use your design, due to not needing this, I'd to thank you for open sourcing it. The world would be cleaner if we'd have all the schematics
I just ordered my kit ! I've been a fan of Elektor for over 40 years, so I couldn't let this pass...
Elektor fan since 30 yrs. Good man
Great work Scott. Congrats for that next milestone.
I'm glad you and your channel have been so successful.
Thank you so much!
@@greatscottlab kit both links broken
NICE!
I think the 5V 12V switch should have been a jumper of some kind.
You don't want to run the risk of accidentally changing to 12V
That's why GreatScott! gave us the 12V indicator LED. It will tell us right away why our powered devices released the magic smoke.
@@PeteBo lol. That's right!
Congrats on the elector project. Useful as always and thx for sharing.
Congratulations on the collaborative project!
Most underrated electronics channel on TH-cam!!
Wow i just clicked the notification. This is uploaded 8minutes ago now and it has already 2.4k views amazing!!!! Thanks for the video I learned a lot in this channel. Hello here from Philippines.😊
Thanks :-)
I hope you make it 'adjustable' for voltage discharge protection some people don't like to push battery to 2.5v
Not just the discharge, I personally like to go for a charge cycle range of roughly 4.1v to 3.3v I think the slight loss in capacity is generally worth it for longer cell life.
@@vgamesx1 Can you link IC or components and the scheme (if possible) for 3.3v overdischarge protection please?
I only found IC for 3.0v and it's a bit too low in my opinion as well.
Yea 2.5 seems low but it also sounds like getting an ic that stops above 3 is difficult. Might be better to consider that feature as protection for the lipo exclusively and work a cutoff into the workflow/design of the product being powered. I would've loved to see a voltage indicator even if it was just a handful of leds to make it easier to stop manually. Not hard to add tho.
2.5 v will be an issue for LiPo batteries, but Li-Ion would tolerate this much better without degrading the cells. With the size of the circuit board I could see wiring up a pair of 18650s in parallel for 6000 mah capacity working really well.
@@Ricardo-sx7ez Sorry, I'm not aware of any ICs that do that, there are some with a reference pin that can allow you to adjust the voltage but if I need that functionality I'll just use a microcontroller and there are a few ways of doing that, you use the onboard ADC, add an external ADC or use a voltage/current sensor.

It's a bit on the pricey side for battery monitoring but there's also the diyBMS project which I can highly recommend or just search for "how to measure voltage / monitor battery with [preferred micro of choice]"
I’ve done a lot of soldering but almost no surface mount soldering. I needed the capabilities of your design so I ordered a kit.
I have a fine soldering iron and tips that work with the 1206 parts. I found that good lighting and some magnifying glasses were required and bought some thin solder and paste flux that worked with it.
Yes the transition to 21st century hand soldering is possible! The work can be tedious so frequent breaks are quite helpful as was periodic cleanup of the solder residue with 91% alcohol.
The circuit worked just fine when completed. I wanted a protected converter of 12-14V to 5V for a QRP-Labs Ultimate 3S WSPR transmitter and find this project served just fine.
Thank you for making this available!
I was so busy, got the notification, but wanted to watch it relaxed, while having my coffee - here I'm now, always interesting video - thanks GREAT 👍👍👍 SCOTT!!!
ABOUT TIME.............congratulations on the Elektor project.
Thank you for sharing this useful designs 🥺. Found it very useful for my final project.
Congratz on the kit! Hope these will be available pre-soldered in the future.
less than 2 minutes in and I bought one! thanks!
Just finished building one of these bought from SparkFun. Works great! Nice little kit - great instructions - worked first time. :)
i don't know why your not making kit's all the time because, loads of your projects and your DIY OR BUY projects are brilliant.. and i can see them doing very well mainly because of your channel. us people who will be buying them know we can trust the source.. P.S. love the 12v option on it : ) very good choice!!
Congratulations on the kit from a long time subscriber.
Thank you very much!
congrats on the kit. Looks useful !!
You and ElectroBoom are my best teacher
Great video by Great Scott
4:54 放电完成 = discharge complete
This is a great circuit, i love the 5v 12v combo.
This is great news. Really excited about your projects in kit form. I'd love to see them all, but I guess you should start with the most popular. Thanks for all your really excellent work 👍
Nice you made it free for all to enjoy 👍
Absolutely amazing project! Thank you
Voltage meter kit, oscilloscope kit: single channel or dual channel, signal producer, transistor tester, zvs driver. The list goes on. Your channel is the best. Thank you.
Awesome project!
Love your projects they inspire me to create
Ah, Sunday with your video and a cup of coffee
your explanations are awsome 👍👍
I like your videos 👌
You explain the things very well 👍
Thanks a lot 😊
Nicely done
Awesome cool project as usual! 🤘🤘🤙🤙
Thank you! Cheers!
kudos on the kit
Great video and awesome board! I recommend that you clean that flux with some iso. It'll help the people you influence to clean their boards as well which is just a great thing to practice.
Great project!
I Read title and screamed “YES!”
This looks like a handy device to have, good size too.
Thank you, I love this kind of kit from your very useful project, placed order for the kit.
Other project like soft-starter is also useful.
Congratulations on your first kit. One improvement could be increasing output current to 2 or 3 Amps so that it could be used to power portable projects like raspberry Pi.
Great work!
If the over discharge protection goes down to 2.5 v then using Li-Ion cells would probably be a better choice than LiPo. 18650 or 21700 would both work well. This is a great looking project kit! Congrats on getting it all together.
No graphs?
Thank you for another great video. I love your scientific approach in all of your videos.
Thank you Great Scott.
You also showed that you went through the trouble of measuring the output voltage/current at different loads and at different input voltages. I would love to see the graphs on that. I would even say that it merits a separate video. I'd love to see e.g. the efficiency of the circuit.
Keep up the great work.
Much appreciated... as every week.

I'd love to see something like this but for multiple cell lipo batteries! This would be perfect for many of my projects but I rarely use a 1s lipo.
It's really nice to see this project, especially the USB C plug! By the way, you should do something against those iron tips. They look like they could use some good flux or something like that
Great Tutorial 🔥🔥🔥
You should use some flux when soldering SMD, instead of relying on the flux inside the solder wire. This way you won't need to dab so much solder into the joint every time.
Excellent very good projects!!!
Oh for sure. Learnt a lot. Thanks
Very good video
This is awesome, I how you do many more collaborations with Elektor
Amazing kit! The only problem I would have is the 1.5A max output current. A lot of my projects need more than that but I know that’s not the point of this. Very cool!
It is a nice learning kit.
It was awasome... Love from India
Really cool! It just so happened that I made a QC2.0 PCB very recently for a powerbank which used a TPS61088 and such an e-Fuse. That chip was QFN-20 and I just wish it was so easy to solder as this one (for SMD standards ofc)...
1) Using some liquid flux for soldering may help for getting better results.
2) For the short circuit protection, limiting the current may be dangerous. I think that part should be updated in the upcoming versions!
All in all, great job and congratulations!
Thanks I was looking for a good one :)
THIS IS AWESOME... I NEED THIS!!!
YESS! Awesome!! Nice work! Buying one or two or three.
A couple of questions though, the over-discharge protection, at first in the video you show 2.9V and later you show 2.5V. Which one is the correct? Also, 2.5v is good for li-ion but isn’t it too low for lipo???
What’s the difference between overdischarge detection and overdischarge release? Is it that once it goes down to 2.5v it will disconnect the load and only until the cell voltage has gone up to 3v it will reconnect the batt?
Just ordered one. Interesting on the Elektor site, the specifications quote: "Overcurrent Detection as 10.0 A", is this a typo ?
I like the USB type C breakout board idea but you could integrate that into the project. If you look on the breakout board then you see a resistor and a capacitor. The resistance for sinking any power is independent of the resistance that will be on the cable's end. So pull-down resistors will always be 5.1kOHM on the CC1 and CC2 pins of the USB type C on your board. Also it looks like there is a capacitor that probably goes to the Vbus line for filtering. In the case that you need a power supply without ripple you would need to filter the Vbus line, after combining all the pins labeled Vbus together, with a 10u capacitor or a Pi filter. As well you see that it comes with the standard communication pins Dp and Dn on the board, well you'd just route them together as a differential pair and wire them to some IC like a serial-to-UART CH340C specifically to have communication with an ESP.
So, maybe this is a silly question, but can I use this kit to charge 18650 batteries? I'm working on a project where I need 12V output from a bunch of 18650s in parallel, and this seems to fit the bill pretty well, but unsure if this will fit the bill or if I need a proper BMS instead. The requirement is also that it needs to be able to charge the batteries with USB.
Yep. 18650 will work.
@@greatscottlab Neato! May have to give this a look then. Cheers!
Why don't you use them in series? It's more efficient (and more complicated to balance)
A lot in parallel with boost converter could work, depending on current needed, if it's very low, I'd go with single or parallel, if higher I'd go 3s with bms, and balance, maybe use a buck boost to regulate output, they make tiny 3s charge boards, that could use USB with boost to charge im working on a similar project, but low current, 1-2amps, 5amp max,
Although lifepo4 will work for 12v much better with 4s coming to 12.8v nominal, and 14.4/14.8 full charge, and is much less flammable !
Great project by the way nice shirt ❤️
Great updates Scott!. May I ask, how can I modify this circuit to work with a 2s lipo battery to output at least 2.1A (for use with servos and steppers motors)? or are there any commercial pcbs like this one but for 2s and at least 2.1A?
Awesome project
Hats off MÀñ 👏👏
I would love to see a boosted board kit. 😂
You can build one using MC34063 IC, for example 5V to 12V
@@RANDOMfilmsOFFICJAL Try looking up what "boosted board" is ...
Awesome project! Love it. Request for future project, convert an ordinary clothing iron to an SMD hot plate. Lcd/led display to shows target temperature and real world temperature.
Thank you for sharing this project , but can not find the link to the project files (schematics & Gerber)
As you told in the video that the schematic are open for all. Where can we see them. Any link
GreatScott you are really great and awesome!! now we can save so much money on our diy projects. i love your content! your channel was the reason for me to start electronics. that transparent gameboy you did years ago! achja könnte auch deutsch schreiben xD weiter so und danke für deine arbeit!
Great project
Isn't 2.5V too low for a lipo battery ?
If i buy the Kit, can i change the over-discharge to trigger at 3.00V ?
@GreatScott!
Just watched your previous video related to this an hour ago.
BTW nice effort...Would you sell the already soldered verion that we will just use right outta the box??
Hey, great Video! I plan to actually salvage a Battery from an old tablet that I no longer use. I think that with that circuit, it could make a great Powerbank!
super upgrade. om my christmas list.
Thankks for info
Great! I would love to see the DIY Intelligent Charger Kit circuit board.
Will it be possible to add a potentiometer instead of just having two set voltages?
I waited it for you!
Great Project. Is there any chance of getting a pre assembled module rather than a kit for those who don't want to solder SMT components?
Do you use leaded or lead free solder? I started using leaded about 3 months ago and it's made my soldering much better.
For the battery charging side, is there a setup that would allow a higher voltage battery? Like some kind of b-directional buck-boost.
I have a few questions on the BOM Management, Did you manually enter the Price for 1,10,100 or any other software/methods?
I want all of your projects as kit😂
Is it necessary to add an additional LiPo protection IC to the LiPo battery when they already have a circuit board attached to the battery (PCM)? Btw, thanks for sharing your knowledge GreatScott!
Can`t find stand-by power of the circuit in specification and video - was this measure?
Thanks Teacher
I was wating this video for years
Does the charge chip have MPTT to allow battery charging from a solar panel?
For handsoldering 2-pin SMD components i find it most comfy to pre-tin one of the pads. if you do this, the part doesnt bounce around and also the connection is cleaner.
Following you since I started my Instrumentation Engineering and I displayed many of your projects in my college and received great appreciation. I gave full credit to you and used your EasyEDA designs to explain things to professors. I liked the short circuit protection video the most being an Instrumentation Engineer. And now in my final year in 2020-21 its a hats off to you that you are doing great. Love from India and thanks for always been my project partner and always the goto TH-camr whenever I don't understand certain things ❤️❤️❤️❤️
thats a circuit i can use in most of my projects!
Does this circuit allow you to charge the batteries safely while powering the load from the charge power source (charge and play)?
Great video!!!
Thank you!!
