In this video i have made 12v auto cut off battery charger circuit without relay instead i have used current (shunt regulator 431) that shuts off current at output when crossing 13.4 volts,
Thus protect and prevent battery from over charging.
You can increase or decrease cut off by changing 1.5k resistor.

[@CreativeTechos]

Yes absolutely you need 14.4v Max output voltage. You can check new improved version of this circuit with precise & adjustable cutoff. Video link th-cam.com/video/nvlOeDHkwK0/w-d-xo.html

[@ibukunoluwabenedict8002]

Very good one

[@CreativeTechos]

Thank-you

[@peterbetts8740]

Two problems here,
1/ The output voltage is determined by the input voltage. If you want to accurately control a battery, you need an accurately controlled supply. This because the output is derived from the voltage divider that is the 1K5 resistor and the 330Ohm resistor
This might be OK for a Lead Acid battery but NOT for a Lithium Ion battery
2/ All the current going into the battery must go through the big MOSFET. As shown and without any heatsinking, it stands a very real chance of getting insanely hot - and what happens then is anyone's guess.
Thus, Do Not Use this circuit for Li-Ion batteries

[@CreativeTechos]

It is actually not for lithium batteries as already mentioned for lead acid batteries in thumbnail, Here is another upgraded versions of these controllers

Amazingly simple setup!!! Please would you tell me which resistor should I tweak to set the TL431 to 28 volt or 30 volt cut off? To charge a 26 volt battery.
Thank you!!

[@CreativeTechos]

Simply change 330 resistor with 10k variable resistor and set cutoff point.
(If you want cutoff when voltage reaches 28v, you need to connect 28v at output and slowly rotating variable resistor till green led glows.

You can simply use a 10K variable resistor instead of 330R Resistor and use variable power supply to calibrate the cutoff on your desired voltage.

When you change the 1.5k and 330 Ohm resistor. They give the reference voltage to TL 431. When you increase the 330 Ohm the output voltage is also increasing. However, I'm not sure of the design max voltage of some components (e.g. elco).

Hii there, yes you can use this circuit for 12v 100ah battery. And set voltage to 14.4v and current Full.

[@weirdcreatures4985]

Why are you increasing input voltage to test it? Shouldn't input voltage be constant (around 14v)?
Also, why you connected a diode on the output? Even if bettery will full charge, the circuit wouldn't get the voltage of bettery due to unidirectional property of diode.

Actually this circuit works on drop voltage by connecting battery and when voltage touches 14v it cuts off, I used variable power supply for demonstration,
