Nice video, and very well explained! Thanks a lot for the circuit, I needed it! Very useful! Greetings from Argentina! 😄

[@georgesdibeh7826]

Hello sir can i use this circuit for a 60 amp charger ( 2 30 amp smps chargers)?

[@MrPierref4]

I am not an electronics guy, but I found your explanation the clearest of all I've seen, and I've seen dozens. I am particularly interested in how electricity flows and changes on a circuit. Could you explain on another video? Congrats for a great instructional demonsrration.

[@madhusudangupta3661]

Hi Teknoistix, The concept of second pot with the relay coil is not understood. How the sensitivity of the circuit to trip relay will work automatically by pot2. Kindly explain. In case, it is unexplainable, kindly improve the circuit for automatically cut on full charging.

[@mansoorahmed2490]

I really like the way you explain. You are really amazing. I have tried to build the same project by following the circuit diagram which u have drawn but the cutoff is not working and also the voltage is not changing. Could you please provide me the easy way to follow and create the circuit for this project. Please help

[@kartikeytiwarixiia0579]

This circuit not works , increase supply to increase voltage But it will not cut off automatically

[@electrotonics]

I think this circuit is only for 12v cutoff because of relay less than 12v it will not cutoff because 12v relay can work min on 9v max 12v so if we need cutoff for 4v we would need 5v relay not 12v

[@premik3880]

This is a wrong circuit he didn’t show how the relay cuts the power when going to certain voltage

Can i charge 12volt 14ah Lithium ion battery plz replay😊

[@jprakaah]

Yes

[@kchandrakant50]

As the power supply is variable, how the 12volt relay can function properly if use 3 volt or 6 volt output to charge anything in that range. For that you need to feed the relay coil directly from the 12 volt DC output of the transformer.The cut off circuit is wrong in this respect.

[@electrotonics]

I think this circuit is only for 12v cutoff because of relay less than 12v it will not cutoff because 12v relay can work min on 9v max 12v so if we need cutoff for 4v we would need 5v relay not 12v..

Very good video sir. 1? In it if we r using 12v relay then we must use 12v transformer or if we r using greater than e.g. 24v then we should give 12v supply to 12v relay either by using 7812 regulator?

नमस्ते बन्धु, आपने बडा ही अच्छा व सरल सर्किट बताया है। 👌👍 कई दिनो से मुझे एक 12 वोल्ट 3 एम्पियर चार्जर की नितांत आवश्यक्ता थी। आपके सर्किट की Amp. कैपेसिटी तो मै LM 317 के साथ एक 2N3055 सीरीज़ पास रैग्युलेटर के तौर पर लगा कर, व 3/5 Amp. के डायोड लगा कर बढा लूंगा। मगर मुझे कुछ इस सर्किट को ले कर कुछ अन्य शंकाऐं हैं। 1) सर्किट मे रिले कौन सा (कितने वोल्ट की क्वाइल वाला) लगेगा, इसका कोई ज़िक्र नही है। 2) अलग अलग वोल्टेज की बैटरी के लिए अलग वोल्टेज वाले रिले लगाना पडेगा। कारण अगर हम 6 वोल्ट या 24 वोल्ट की बैटरी चार्ज करेंगे तो उस समय 12 वोल्ट की रिले कैसे सही काम करेगी ? 3) 10 K POT", जो कि रिले क्वाइल की सीरीज़ मे लगा है, वह रिले क्वाइल का लोड (33 m. Amp व उससे अधिक) कैसे लेगा ? कृपया शंका समाधान करें धन्यवाद 🙏

So, with a 10k pot on the regulator and one on the relay, I'm assuming you can adjust the charge voltage separately from the threshold/cutoff voltage?

[@madhusudangupta3661]

Angle Bargle, Voltage regulation of LM317 is achieved by the dual resistance connected with it and not with the relay. Pot2 in series of the relay can only regulate current through it. Nothing to do with tripping of relay wrt the voltage or current output for charging. I am really at loss to grasp the basic theory behind pot2 in the circuit.

Sir🙋🏻, Your explanation is outstanding, however I have two questions; 1. When voltage is adjusted to charge battery of 4 to 7 volt then it can never drive 12V relay as it needs at least 9 to 10 volts approx. 2. When voltage is adjusted for charging 12v Battery then the potentiometer-connected to relay will get damage when it is adjusted to the minimum values due to high current. Can you please clear my confusions? Your reply would be highly appreciated. Regards

[@electrotonics]

I think this circuit is only for 12v cutoff because of relay less than 12v it will not cutoff because 12v relay can work min on 9v max 12v so if we need cutoff for 4v we would need 5v relay not 12v..
