Your assembled Circuit differs from the schematic. In the schematic there is no resistor at the LEDs junction.

[@mimomimo7370]

As soon as it is turned on, one LED will burn. When the voltage reaches the limit, it will burn the other one. The circuit current is limited by the 1n5408 diode. If the missing resistor is added, the scheme will be ok

Question: What about an 18 volt charger? Are the components the same or components with a different value?

Will your circuit works on 150AH battery?

[@zuchamotungoe6817]

Im not sure but i think it will work for 12 volt any ah if it's 12 volt battery lithium ion, Lead acid, lifepo4 etc

I input 15v dc 4A circuit on but not cut off i dont have variable power supply

[@Accumulator1]

Can you adjust the 10k potentiometer so the red LED turn off? Is your battery bad so it never reach full charge?

[@user-tz4ku1de1d]

Yes, because relay max input is 12v broh. If want to high volt input, you must change relay.

[@Ricki63-Ok]

¿Circuit?...please.

What is máximo current

[@nandeepkhajuria2326]

Depends on relay and big diode bruh It's just a super simple circuit which triggers the relay.

[@henryquispe1701]

@@nandeepkhajuria2326 If you would like the current to be about 40A, in relay and diode, how many amperes would it be or what values would they be, thank you

[@nandeepkhajuria2326]

@@henryquispe1701 I would say remove the diode as it's just reverse polarity protection. And connect relays NO and common pin with AC as switch to the transformer. In that case it would easily handle 40A or more But LEDs won't work. So don't connect them either.

Max current it allows?

[@christiankulmann3325]

You can use a 25A Relay.

[@Accumulator1]

​@@christiankulmann3325 okay make the relay 25 amp but the current runs through that 1N5408 diode which is rated only 3 amps.

[@user-dh2jl9cd5g]

Can used for lithium battery packet(4 × 18650 batteries) charging?

[@Accumulator1]

Shouldn't your 4S BMS control the charge to your battery pack?

[@wirebrushproductions1001]

No. Can only be used for lead-acid, and it's not very good at that.

Horrible, horrible circuit. Your schematic leaves out the base resistor for the transistor. Without it, the pot cannot be adjusted to anything greater than about 0.7 volts, and if you turn up the pot at all you will destroy the transistor. The LEDs are the type that contain an integrated resistor so they are normally running on 12 volts. The "charge" and "full" labels are on the wrong LEDs, and they may be connected to the wrong relay pins. The charge current is set by the current limit of the DC input supply. Use a supply with too much current and you'll damage/destroy the battery. Like I say, a horrible circuit, and you should be ashamed of yourself.

[@noone-zq7my]

Agree , the schematic is wrong . Looking at the actual build in the video there is a 15K ( or 1.5K ? ) resistor connected between the variable resistor and the + 14 volt input . The relay appears to be labelled correctly but the LED's are not . The anode of the green LED is connected to the normally open contact on the relay and the anode of the red LED connected to the normally closed contact as is the output diode 2n5408. Note in the video he adjusted the 10K pot so that the red LED just turns off ( full ) and the green LED turns on ( charge ) , yet when the battery was connected the red LED came on during the charging cycle. 2 hours later the red LED turned off and the green LED came on indicating full charge ?
