Ise video ko dekh kar achhi tarah se samajh me aaya issi tarah se video banani chahiye, kyo ki aapne diagram ke sath me components ka name our number + volt+ kis jagah kya lagana chahiye poora diagram samajh aa gaya, thank you sir ji
Very nice setup and video with explanations Can you tell me how to get the cutoff at 13.8 volts as I want to use it as long time float charger Please reply and thanks
Hello, I'm wondering what serves to limit the current from the power supply to the battery? Does the regulator limit the current or is it the resistor connected to the battery? Also, how does the TL431 handle the back EMF from relay inductor coil? Thanks
I have an important question for you, and I hope to respond quickly, please, if possible, which is whether it is preferable to use the IRFZ44N MOSFET or the transistor power E13005A in designing an integrated charging circuit for lithium batteries included in the TL431 transistor, and I wish you would mention the reason, and thank you very much.
Actually battery needs to be connected first then input dc must be connected, When I disconnect battery the resistor triggering bc547 senses battery is full because voltage & current returns or rises to cutoff refrence. And that's why to restart charging battery needs to be connected first, then on full charge it will cutoff automatically.
@@CreativeTechos There is no bc547 in this assembly, so I still cannot understand the operation of the system since the voltage at the cathode must be: Vref(1+2.2/0.47)=14.2V, the relay should not get excited! Can you provide us with more details on how it works? Thanks in advance
Yes, you can but you need to use 5v realy instead of 12v also you need to replace 2.2k resistor with 1k and instead of 470 ohms Resistor you need to use 1k variable resistor to set your desired cutoff voltage.
Nice, dude i have an important question, im going to charge 2 of 6 volts batteries in series my power supply can give me 12v 6A max , we have i and we have a diodie in the circuit we know the diode takes 0.7v lets say as a tax to enter so now i have less than 11.3v to work with , how can u solve this problem?
i want to ask, I'm still a kid but I'm curious how the battery charging work and i have this question in mind that bugging me.. do i need a high voltage compared to a battery like for an example i have this 12 volts battery do i need a much higher voltage to charge my battery? like in your video 14 volts is what use there
If you cut off the charge at 14 volts, the battery will be charged to 80%. After the voltage rises to 14.4 volts, you should wait for the current to drop to at least C/20.
As I have used 1n5408 general purpose Diode, 3A output max, if you need higher current eg, under 10A use MIC110A Diode. The input must be 14v to 14.2v max & 10A maxx
Yes, I appreciate your opinion, also it will be even more easy for me to built. But some people understand and follow video & in air circuits connections are more clear.
@@CreativeTechos agreed, and sometimes it will provide more clarity on some circuits. I know that it's asking for more work from you as the creator of this great content, I just think that seeing both free floating and perf board methods will help us (your viewers) understanding more completely and can act as lessons for circuit layouts. Thank you for your response and I look forward to seeing more of your work.
Dear sir. With reference to your I require 12 volts auto cutoff battery charger pcb 12 pcs Secondly I need 24 volts auto cut off battery charger pcb, itis possible to use the 12 volts pcb by charging the24 volt relay and resistors values increase pls advice me email id

Thankyou so much for your love and appreciation 👍
Nice, very simple and very good, keep it up
Thanks for watching 🙂
Lo hice y funcionó perfectamente.
Thanks for watching my friend 🙂
which resistor can be replaced to trimpot in order to adjust cutoff voltage?
if I wanted to do this for a 21V lithium battery, should I increase the values of R2 and R3 (about double them) and replace the relay?
You can just add a bms for your battery pack
Muito top legal circuito 👊✋
Very nice setup and video with explanations
Can you tell me how to get the cutoff at 13.8 volts as I want to use it as long time float charger
Please reply and thanks
Very nice circuit thanks
Suppose I want it to cutoff at 13.8 volts which resistor should I replace 470R or the 2.2 k
I think u should try a variable resistor to set a fixed voltage limit. that way u will also easily find out which fixed resistor u need.

Very nice.

Is it work in low cut, high cut ?
Is this circuit connect the charging again after the battery will empty?or It is for cutting charging only?
thanks ❤
There is another circuit video on my channel that automatically cut off and on charging to battery
@@CreativeTechos Thanks.
So nice thanks
Instead of TL 437 which transistor se can use.
TL431 is adjustable voltage shunt regulator, it has no substitute, but it is easily available in market.

Why you should disconnect first the negative line to light up the red led??
Actually battery needs to be connected first then input dc must be connected,
When I disconnect battery the resistor triggering bc547 senses battery is full because voltage & current returns or rises to cutoff refrence. And that's why to restart charging battery needs to be connected first, then on full charge it will cutoff automatically.

Min amd max input dc range???
Can i use this protection circuit for 12v 6amp battery and solar panel.? Plz reply... thankyou 😊
Yes you can use it, to make it work perfectly, input dc must be fixed at 14-14.5v
@@CreativeTechos the solar I'm going to use gives 14w 4A current....(will this okay)
Yes, perfect 👍
Bahi input current mobile charge da do to work kary ga ?

This is work battery lithium ion & polymer?
is it suitable for 12v 60a battery charging??
Nope maximum 10 amps
Circuit diagram
No because maximum relay current is amps is 10 so don't use maximum amps
can i use a 1n4001? thanks
Instead of 1n4007 or 1n5408?
@@CreativeTechos yes
You can use any schottky diode instead of IN5408, 2-3A must be used for 7-8 ah battery
@@CreativeTechos I meant instead of 1n4007
Yes you can use 1n4001 instead of 1n4007
Good

You need 13.8V to charge a 12V lead acid series of cells.
Why not two diodes and charge in parallel?
Nice
Thanks for watching 🙂
Thanx
My pleasure 🙂, Thanks for watching
brooo. what the output current of this circuit
Depends on input current & output diode, max 10A
and TL431 2nd pin is Anod?
Is this auto discharge and charging circuit pls. Reply thanks
I'm asking thanks.
This is auto cutoff charging after full charge, it will protect battery from over charging
How Skema? To cutoff dc 55 volt
i want to ask, I'm still a kid but I'm curious how the battery charging work and i have this question in mind that bugging me.. do i need a high voltage compared to a battery like for an example i have this 12 volts battery do i need a much higher voltage to charge my battery? like in your video 14 volts is what use there
and how can i limit the battery to not overcharge and over discharge? how it works?
Does this circuit work with 5v and 2A input DC
No Minimum 12v

If you cut off the charge at 14 volts, the battery will be charged to 80%. After the voltage rises to 14.4 volts, you should wait for the current to drop to at least C/20.
