Good hardwork keep it up ❤

[@veeem3964]

What a great circuit
Thanks for the same
Keep up the good work

[@anuragprojects]

Thank you

[@luimobiletech]

Nice 1, i will try it on my next video,

[@user-un2ni8dl7y]

Good work 👍

[@kabandajamir9844]

So nice thanks

[@anuragprojects]

Most welcome

[@hightechelectronic3140]

Ya circuit minimum kitna voltage per cut mar ti hai

[@Elarpachuau]

what does that potentiometer do? And how can such low amperage charged full only at one hour? Does ic amplify the amperage?

[@unnikrishnan6608]

Good circuit

[@anuragprojects]

Thanks

SIR 3.7 V IS STARTING VOLTAGE OF LITHIUM ION BAATERY.THE LITHIUM ION BATTERY ARE FULL CHARGE IN 4.2 VOLT.PLEASE SOME CHANGE THIS CIRCUIT.

[@shahahmad2920]

nice... it works. What is the variable resistance for?

[@anuragprojects]

10K ohm Resistance

Nice video

[@anuragprojects]

Thanks

[@uniqueworld554]

Output AMPS bhut km h bro is circuit me

[@John_Smile]

It still needs to be adjusted!
The battery is full at 4.2V, not 3.7V.
And the charging current of 0.25 A is very small. You need 10 hours to charge a battery, not one hour !

[@hmax1591]

Incorrect....a battery is not full at the charging voltage...3.7 battery needs 4.2 volts to charge it to 3.7...which is what the battery is rated for. Is a 3.7 volt battery not a 4.2 volt battery.

[@Qaiserhayatkhan]

Nice

[@anuragprojects]

Thank you so much... And Thanks for watching my videos!

[@hmax1591]

I need 3.7 output to charge 3 volt cell batteries.

[@ErAdarshSachan]

Okey 👌 I try for you

[@PedroGarcia-mf8ix]

Para cargar una pila de 6 volt que se debe modificar?

[@hmax1591]

Hay que hacer un circuito nuevo. Para cargar una batería de 6 voltios no hay que hacer un cargador casero....eso se puede comprar..

[@paulmat5072]

Pełne naladowanie to 4,2v a nie 3,8v

[@arajasujathaars6894]

Super boss pls small dought i have to try two batteries..💐

[@collectorsinfo]

Looked nice & simple in the picture, but wasn't.

[@ardiansah3022]

Apakah bisa memakai JRC4558D ???

[@ErAdarshSachan]

Any op-amp ic

[@ErAdarshSachan]

You can.

[@rtxgaming6905]

12v auto cut off plz make

[@anuragprojects]

Yes bro... i uploaded pls Watch 12V Auto Cutoff Charger czcams.com/video/Bo-HDYzGTaU/video.html

[@larenethunter4873]

To many components :-)

Bu devreyi 8.4 12.6 16.8 v uyarlamak içın nasıl degişiklik yapmamız gerekiyor

[@adbulkadiralithabit2641]

Hello

[@SAFSuperamazingfacts]

Waste of time

[@jawedakhter2269]

Showing only ic and putting so many component. What a joke.
