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.

@Carolina-mw4po 2 года назад

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 2 года назад

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.

In your comments you answer requests for using other than 14V input and give a variety of answers. I am thinking of using the circuit as an add on to a simple bridge rectified battery charger. Could I replace a resistor on the input with a trim pot? Would I replace the 330ohm resistor or the 1.5Kohm resistor on on the left of your circuit? What size trim pot would I use if this could be done?

@CreativeTechos 2 года назад

You can add bridge rectifier as dc source and you can add trimpot instead of 330R resistor to adjust cutoff voltage, but its important to keep dc voltage under 14.4v. That you can get by using lm317 adjustable output with bridge rectifier circuit externally
