Very useful circuit and I tried it. It indeed cuts the voltage when the battery is full but as long as the circuit is connected to the battery red led remains lit.
not sure why red led would remain lit as i haven't tested the circuit, but if you are concerned about green led draining the battery you can disconnect it. the red led should go out when the battery is charged.@@omodeindemustopha9270

@@CreativeTechos i mean i want to charge a 12 volt battery with a standard 12 volt adapter and when the battery is charged this circuit will automatically stop charging
Yes, when your battery is full, it will stop charging to battery. You can check new improved version of this circuit with precise & adjustable cutoff. For lithium ion batteries each cell needs 4.2v multiplied by number of cells in series needed to be set as cutoff voltage, Video link th-cam.com/video/nvlOeDHkwK0/w-d-xo.html
Thank you for all your videos. Very informative and helpful. One question, can the 431 shunt regulator be substituted with another type of regulator? Or something equivalent to?
I was quite interested in this circuit but see that the green led is connected the wrong way at 2.33 into the video and the tl431 is also connected incorrectly. The reference pin should be connected to the junction of the two 4k7 resistors and the anode should go to earth. Having said this, I still don't see how the circuit works as the voltage of the battery isn't monitored, so what causes the TL431 to switch off? Could you explain how the circuit works?
In video it is connected correct, but diagram in video has mistake that i was not able to correct after uploading, But download link in video description has perfect diagram
Actually N channel mosfet remains on by feeding small +ve current at gate using 1k resistor. And the Tl431 pin 2 connected to -ve and reference pin 1 connected to Voltage divider, when voltage in circuit reaches above 4.2v, refrence pin 1 of tl431 receives enough positive current and switchs -ve Voltage from pin-2 to pin-3 that is connected to gate of mosfet, that grounds positive current coming from 1k resistor hence mosfet turns off.
@@CreativeTechosSo, reference voltage is 4.2 or 4.8 according to 4.7k and 4.7k+220 R, it is? if 4.2v, how to calculate to get resistor value for voltage reference? Please, let me know.

I have a question... I already have two leds that are controlled by a micro, so how do I have to conect that circut to the micro so that the micro detect when the batery is in process of charging or is full charged? Is as simple as conecting the input to where the anode of the led might be? or I can take out the leds?
Hello, I tried it with the video circuit (I captured the screen) and it never cut despite not charging anymore and the red led was permanently on, I clarify that I used a new 3.7 battery that was fully charged and I discharged it a little to load. Looking at the circuit in the video with the one in the description there are differences, I used the one in the description and it works fine now. Thank you! I want to make a contribution, I removed the 220 resistor and put a 10k potentiometer as you suggest and you can effectively regulate the charging voltage as a previous user consulted. Greetings.
Yes, There was actually led polarity mistake in video diagram, and corrected one is already uploaded download link is in video description, and you did perfect to use 10k pot to adjust cutoff voltage. Thanks for watching 😊
@@CreativeTechos exactly, that was the error of the diagram. Now it works fine, I think, only that I have to adjust the cut-off point according to the battery I am charging, for this I am trying with a 10 kΩ potentiometer. I'll tell you how I'm doing on the tests. A question, I saw a similar circuit of yours that placed a 6Amp diode at the output to the load, is it convenient in this 3.7 volt battery charging circuit?
Yes, you can use that too, connect diode on output positive before connecting to battery, to stop reverse discharging, also 4.7k resistor that is connected from pin 1 of tl431 to direct input positive, instead of direct positive connect it to battery positive after diode. It will help to cutoff at precise voltage.
Hello and thank you very much for your video, very useful. A question, what modification in the circuit should I do if my battery is 1.5 volts? Greetings
I assembled exactly as in the downloaded scheme. 1. The green diode is off. 2. When the battery is connected, the red diode does not light up. 3. The voltage supplied to the battery is 5 volts. 4. The voltage does not change with a variable resistor (replaced 4.7k + 220 ohms with a 10k variable resistor). Is the circuit not working or do I need to fix something? I will be grateful for help. Thank you.
Sorry to hear this, but make sure TL431 ic is worky & mosfet too, also trim pot will not change voltage, you just need to connect variable power supply and set voltage to suppose cutoff at 4.2v, then move the trimpot till green led turns on, Then your circuit is calibrated to cutoff output when it is reach 4.2v, Connect battery first, then plugin the charger, you'll see Red led on, Afterl full charge green will turn on.
@CreativeTechos, Whether the circuit can take higher input voltage than 5v from usb. What is the input voltage range for the circuit. Can you suggest equivalent for the 431. For parallel charging of more li-ion cells requiring charging current exceeding 1A, whether the same mosfet an be used with appropriate heat sink.
Yes this circuit can take 5-24v input, also irfz44n mosfet drain current is rated 44A as per datasheet with good heatsink, I will soon upload adjustable cutoff circuit can that can be used to charge any range of batteries of 5-24v, Also you can use same above circuit for charging upto 5 cells in parallel with good heatsink on mosfet, and using 5A 2A charger
@@CreativeTechos So many thanks and my heartiest well wishes for your continued renovations and simplified projects. Kindly educate about the use of TL431 shunt regulator. How can it be eliminated with simpler component(s).
A large voltage cannot be applied to the input of the circuit because the protection circuit that is built into the battery will fail. I do not recommend a power supply voltage higher than 8 Volts.
You can apply max input 5v for 3.7v battery, Otherwise it will not fail but will remain in Cutoff state as this circuit is designed when voltage reaches 4.3v it goes in cutoff state.
@@CreativeTechos In case of poor contact at the terminals of the power supply, "rattling", the MOSFET will open for a while until TL431 gives a "command" to close it. And all the power supply voltage will be applied to the battery. If the supply voltage is approximately higher than 10 Volts, the protection circuit built into the battery will fail.
Hello Thanks for sharing and explanations but unfortunately you have a mistake in the drawing, the practical assembly is correct but different from the drawing you presented. The junction of the two 4.7 kg resistors should connect to the No. 1 (reference) leg of TL431 and not to the Anode and again as shown in the drawing. And the Anode which is the middle leg 2 should be connected to the resistor junction 220 ohms and 15 k ohms Hope you get the comment easily and comment Thank you very much
Can the input voltage comes from a 5V 10A power supply. I assume that it draws only the 1 amp it requires right? So we do not need to limit current. Nice video. Subscribed
