Sir, I have just watched the vid, and it looks simple and plainly understandable from a layman's view. I dont know if it will work, but I will definitely try it, cos it has few components. Whether it works or not, I do appreciate your method of explanation, and God bless you. I shall come back after put it together into practice, many thanks.

Sir was osome. Great knowledge u have Sir I want to charge a 12.6v (2p, 3s) lithium ion battery of 4400mah..... So I use a 12v, 2A adapter and also tried 1A adapter also.... But adapters was heating a lot with in 5min of charging.... What should I do.... Plz guide me for proper charging methode..

[@dayasrinivas]

will it auto cutoff on blinking green LED

[@basitsaifi6562]

Can I use lm358 ic without changing anything in Circuit?

[@amitgohel5616]

12v battery charger me used kar sakte he???

[@DIYwithBatteries]

10k pot (blue) is working perfectly and also bro if we attach a PNP transistor 'E' to +v,'C' to -v and the 'Base' is connected to the +v terminal of the LED (green) . Cutoff's charging when the batry is full (basically it's not disconnect the power supply but it keeps constant voltage & current draining by the transistor use heatsink compulsory) turns on and keeps the voltage constant 4.2v,4.0v,3.9v at what voltage u want to turn on by rotating 10kpot. Anyway thank you baya🙂 meruko ye circuit buhoth important hee kuoki mere pass bohot 18650's batteries he per isa circuit thanks a lot bro good explanation continue like this for every video. Thanks man

[@rafiulmollah]

In place of green light we can use small buzzer for indication.

[@f.m.a5928]

Nice video.I think it is just for indication but I am looking for auto cut off at full charge for batteries from 3.7 v to 12v.plz help.

[@FreeCircuitLab]

U can use a transistor instead of the diode to cut of ,the base of the transistor will be connected to the output of the ic. And ofcourse u can use a relay to cut the ac supply to the charger

[@jkcutz9586]

@@FreeCircuitLab which transistor. Number

[@manertk1636]

[@FreeCircuitLab]

Okey, it will work but you have to choose the right resistor combination. it may be difficult because resistor for every value range is not available

[@subratababundas]

How to blink any one of LED bro??I added a strobe light circuit to the LED terminals..but its not blinking

[@FreeCircuitLab]

Are you using 555ic ?

[@elbinv]

@@FreeCircuitLab no..the same circuit in that video added a BC547 transistor instead of IC 555..I took the output of green LED to a 3 volt blinking circuit..but unfortunately its only lighting normally..I wonder why its happenng??the blinking circuit is operating normally when directly connecting to a 3 volt battery ..I hope professionals like u can find a solution for this😁☺️thank u bro

[@FreeCircuitLab]

@@elbinv probably your circuit requre more current which the op amp ic can't deliver. Check the input voltage to the blinking circuit remains 3v or dropped.

How can we compare a battery from same battery.

There is not a single battery. Actually there are two, the fixed one is the 5v supply from charger, which works as a reference and the lithium battery works as a test subject. The voltage difference is equal to the drop across the diode.
