In this video, I'm showing you guys that, how to make a adjustable battery full charge indicator circuit for 6v / 9v / 12v battery.
It is actually working by using TL431 shunt regulator ic.
which turns on by giving refrence voltage from voltage divider, that includes a potentiometer which can set the cutoff point.
Part List_____
1) TL431 Shunt Regulator
2) 3x 1kilo ohms resistor 1/4w
3) 1x 4.7 kilo ohms resistor 1/4w
4) Red & Green Leds 3 or 5mm
5) 1x Schottky diode 1-3A

6a10 diodes can be used
All the best👍👍👍🎉
Sohottky diode 3amp I can use 6v.9v.12v battery as per I adjust potentio meter, if Tp431 getting more heat so what can I want to do?
Best videos I ever seen in your videos . Bravo
Thanks ☺️
Exelent job my friend. I have just build it and it works 100%! JOB WELL DONE.
If I want to charge battery at 10 Amp current which Diode should I use?
this charger is very nice & simple,
thanks a lot for this.
,
My pleasure 🙂
Very good. It want so this circuit
Thanks 😊
Great video and thanks again on the diagram. Can you make a video on how to make a circuit board for your projects. That would be great. Thanks again for your learning video's,
You can simply assemble it on zero pcb,
Or if you want to learn professional designing of circuit boards i use Kicad
Thank you I'll go to the website.,
Thanks for this wonderful project in a very easy way thank you soo much..
My pleasure 🙂
Great idea. However, the voltage divisor may drain the battery too fast. How about using a 47k and a 100k potentiometer?
Good video and good learning experience
Thanks for watching 🙂
Thank you … Very useful. How about for bigger Ampere ? Example for 20 Amps.. What Diode should I use ?. And TL431 as A Shunt Regulator can still using ?
No changes required, same can work with these batteries too, Max voltage 18v
Nice and helpful circuit. Quick question, how can I calibrate this for charging a 24 volts battery i.e. what changes in resistor values do I need to do?
These are really good. Every student interested in simple electrical circuits should try building these. Have you created a library of your circuits yet?
Thank you sir
How make a battery cut off system without relay for 4.7 volt battery
Please help me
Can I use 100k multiturn priset instead of 10 k priset
Good work
Thankyou 🙂
Thanks for the very helpful video showing how to make this full charge indicator! I’m wondering if a bicolor led could be used in place of the two leds, and how to calculate resistors needed to convert circuit for 17.2v to 22v charged Lifepo4 battery bank? Your help is greatly appreciated!
Nice bro it's working 👍👍👍👍👍👍👍
Thanks for appreciating 🙂
@@CreativeTechos hi be
Ro please make a xl4015 modul make video
Hi bro. Thanks for the tutorials. Can this circuit serve as a BMS?❤🎉
Bro can you make video on specific voltage without adjustable ? Like 9v ?
Hey, actually loved your content man!!.... But i have a doubt I am using a 2x 3.7v battery in series to make 7.5v apprx..... My maximum voltage will be 8v .... What should be the changes made in this circuit?
It is simple to calibrate, watch in video again, you need a variable power supply for calibration, set voltage at suppose 8v where you want to indicate fully charged, and then adjust trimpot till green led turns on, thats all.
Batarya şarj olurken kırmızı LED yanan doluncada yeşil led yanan güzel bir devre olmuş emeginiz için teşekkürler, bu devre batarya doldugunda akımı kesiyor mu?
is this circuit support 3s or 4s battery?
Hi, great video suppppper helpful! i have used this a few times now.. wanted to know what id need to change to make the charging light cut off at 4.9V and the charged light come on immediately from there..? Thanks bud
You mean tou you want to charge 4.9v battery with automatic light?
This circuit is possible other use for example mainteiner pb battery
Or lifepo4 battery?
Thank you
Can be used from 6-12v any battery
@@CreativeTechos ok
Now I make it.
Verygood video with explining is it can be use for up 12vdc?
Yes, it is adjustable, you can use it for 12v
@@CreativeTechos For battrey charger 24vdc can be ajdust to 28 what's sircuit /diagram avaible thks
This circuit works for 6- 18v max
does this charger turn off battery power after full charge
Bro one think to know. Is this also work as auto cut off charger after full charged battery?
Good 👍project sir. Kindly make 12v. 4amp. lithium 18650 battery charging circuit module with over charging protection for bike.
Check out this circuit video.

Can i use this circuit in my 3.7v li ion battery sir?can i adjust that to 4v? thanks for response
Very Nice 👌👍
Newly Subscribed.. will it stop charging after battery is fully charged and can it be possible to use this to charge cellphone battery?
Thanks for subscribing, No it will just indicate battery is fully charged, on reaching the voltage where you had calibrated, for cutoff check out other videos on my channel, thanks for watching 🙂
Please tell me schotky diode number as u have used??
You can use SR306
If diode not put. Is hare any problem sir? plz tell me
Diode is must otherwise led will remain always on while not charging
Which Schottky diode
Number please
Can i use FR 306 diode
Nice video sir, I want to ask
When the power supply go off, how about both led status? It is still on or bott off? If one of them still on, I want to know how if I want them both off, if the power source is off
Please guide me
Thank you!!
As you can see there is pass through diode to battery that will block reverse current so both leds will go off when input turns off
@@CreativeTechos noted sir. thanks for your quick reply
What if I remove the diode, the component still working normally?
No, actually diode is very important as it acts as barrier between input and battery, also, circuit receives refrence voltage from battery side to indicate on reaching set threshold voltage
My pleasure Thanks for watching 😀
Bhai aap ka IRF Z44 N circuit diagram wala thik rahega ya ye wala circuit diagram bata dena bhai banana hai
This circuit is just adjustable full charge indicator circuit, that circuit with mosfet is with auto cutoff function on Full Charge.
Can I use 1N 5408 diode??
Yes you can use
can I use this circuit in 18v bro ?
Yes, this indicator can be used for 18 v
Schotkey diode has 3 pins??
Low ampere Schottky diodes come with 2pins, where as high ampere Schottky diodes used in switching supplies comes with 3pin and in TO-220 package.
👍👍👍👍👍
Thanks
Nice info, thanks for sharing it :)
You're most welcome 👍
Can i use 5 ampere diode?? Or can i change with fr307 diode?
FR307 is fast recovery diode and here you can use general purpose diode like 1N5408, but schottky diode that actually have lowest drop in voltage forward
@@CreativeTechos thank you
My pleasure, Thanks for watching 😀
Bro, how to make this circuit with out adjustable potentiometer?
For 12v battery, 12v input( charger 2.5 Amp)
And by way bro, your videos are excellent, I loved the content bro...!
Thanks for watching 🙂, Actually you need to find out the exact resistance needed to cutoff at your desired voltage.
@@CreativeTechos thank you for the reply bro.😇
My pleasure, Thanks for watching 🙂
Very nice sir.
I have a 3S lipo battery. I am using 12V 1.5A power source as charger. Will this work with it?
Please wait some days, I'll soon upload charging circuit for 3s battery.
I want to use 8.4v means two 18650 Battery charging indicator...what changes needed bro???
It will work for this voltage too, just calibration required as shown in video
@@CreativeTechosThanks for your reply..i want to use fixed 8.4v indicator without potentiometer..how to to do that help bro..
Hello, I really like the channel!! Congratulations! I want to make a li-ion battery pack charger for a screwdriver and I have the XL4015, but it doesn't have a full charge indication. I would like to know if this circuit, in addition to the load indicator, has an auto current cut? Grateful!
Please check out other videos on my channel there is already 3.7v charger with auto cut off
@@CreativeTechos Hello. I've seen several videos, which are great, but I couldn't find one that had automatic cutoff for 12.6V battery. Would it be possible to send me a link? Grateful!
Great
can use 12v charger instead of 14.5v?.
and its ok to use 3amp charger?
For how many volt battery?
@@CreativeTechos 12v 3ah battery.
and can also use to 12v 12amp battery?
To charge 12v battery, the charger voltage should be greater than battery voltage, thats why you need 13-14.5v charger
@@CreativeTechos yes,but when you use 12v AC transformer and convert it to DC with few diode&capacitor.the result when you test it w/tester,it will become 13vDC up..right?..
maybe if i use 14vAC transformer then convert it to DC,it will become maybe 15vDC up...
Muy bueno 👍👍
Sir what if I will use it for 18volts. What should I do.are there replacements?
Yes you can use it for 18v, nothing to change, just calibrate it accordingly as shown in video.
Thank you so much sir..
My pleasure, Thanks for watching 😊
Sir is it possible to make a circuit.. to find AC power ... low and high using led bulbs
. When ac power is 220 to 230 glow green and when ac power is below 110v turn red led ON
Can we make it
Yes, it can be made, and i think it will be useful, I'll soon try to upload over here.
@@CreativeTechos yes sir..it really useful thank you... I tried but failed.. i search in RUclips i didn't find any video about this project...
Thank you 😊 for your reply. And waiting for that project ..
Hi, i want ask again 🙂 if i want use this circuit to charge 18650 battery. Are there any components that need to be replaced? Thank you
This circuit is designed for 6v, 9v, 12v batteries. For 3.7v replace all 1k resistors with 470 ohms & 4.7k with 1k.
Also would like to let you know there is already auto cutoff charging circuit uploaded on my youtube channel, you may check that out.
@@CreativeTechos thank you for your information 👍🙏🙂
My pleasure 🙂
@@CreativeTechos does this circuit work with 12v battery pack made with 18650?
Yes, set cutoff threshold accordingly
Pl find circuit for lower cuttoff say 4.7v of battery . 4.7 for green led red for full led
You mean you need circuit for 3.7 v lithium battery?
No.. Lower cuttoff limit at which battery drained and not operat to run toy motor.
Great explanation Sir.
Please how to increase the charging output current for fast charging?
Use 3A schottky diode, also it depends on battery capacity.
I'd start with: "What problem am I trying to solve": Battery on one side, that "drops" voltage and acts like a resistor, and a higher voltage DC volt source on the other side. The goal: Light RED when the battery is charging, light GREEN when the charging is done. The battery voltage goes up slightly during the charging, so this is what I detect, and this is the criteria I'm going to use. Now, Here's how I'm going to do it...
Great! Can I use 1N4001 or 1N4007-B diode?
Yes you can use and will work well, but there will be upto 0.8-1v voltage drop.
That's why schottky diode i used drops 0.3-0.5v
@@CreativeTechos thanks!
My pleasure 🙂
Diagram, ?
Diagram download link can be found in video description
Hi.. I want to ask, can i charge for 18 volt battery? Thank you 🙂
Yes, use 2.2k resistors instead of 1k, and adjust potentiometer for adjusting Full Charge Indicator
@@CreativeTechos thank you 🙂🙏👍
My pleasure 🙂
@@CreativeTechos sory i want to ask one more, there are 3 pieces 1K in circuit so do you mean change all of them to 2,2K? 🙂🙏Thank you
Yes, for 12v 1k is perfect, but for 18-24v change all 1k to 2.2k
Sir , will this circuit charge the battery ?
Yes it charges battery while showing you status.
@@CreativeTechos thanks sir
My pleasure 🙂
Bro kindly do it with usbc charger design.

My pleasure 🙂
Can you add Link to the schematics
Yes check after few minutes
@@CreativeTechos Thanks

Remember that a battery's internal resistance is very low. It's worrying to me how there's no current limit, whatsoever. Nothing but a diode between the DC-IN and the battery. Diode clamps voltage, not current. The weakest link in this loop is the diode, obviously: Dropping 0.7v with thousands of mA on it will overheat it
Will a current limiting resistor on the battery side solve this?
6v battery cut off voltege and input voltege ???
For 6v battery input should be 7.5v and set cutoff at 7.2v
@@CreativeTechos Operates on 10 volt input ?? use lm 317 ??
Use lm317 to set 7.5v input voltage for 6v battery
@@CreativeTechos ohk thanks for answering
Hello sir ye circuit main try Kiya hai per mere pass diode 1 minute me hi bahut jayada garam ho jata hai diode in4007 use kiye hai esa kyu ho Raha hai
