Cok başarılı bir devre👍
nice video
Very well explained. This type of assembly is a true work of art! I liked
thank you.. enjoy
Good Jobs 👍🏼
... Hobi Elektronika Coming 🙏🏻
Maru .good job
Thank you
nice one ....good idea ....thanks for sharing 😊🙏

@Homemade 101, The output voltage for charging 3.7-4.2 volt cell is set around 4.7 volt between diode and led pin. The cell will be exposed for charging to 4.7 volt which is not healthy for a li-ion cell. Moreover the completion of the charging and the final voltage of the cell was not shown to asses the correctness of the proposed circuit. Now my two questions are for you to reply. Qn 1) Any explanation or correction required for setting 4.7 volt for charging. Qn 2) BC 547 can deliver 0.1 amp only for charging. Is this current enough? Will you please respond?
👌
It's been a long time since I made and used this circuit to charge my led emergency lamp.I was afraid my battery( got from a broken power bank) would catch fire and explode if it was not auto cut off when fully charged.This circuit you show us helps me great, it automatically cuts off and I am very relaxed without any worry whenever I charge my battery. Thank you so much.
@madhusudangupta You are right!!! They have no knowledge about this components. It might be copied diagram from others whatever you said about charging voltage. Yes , it should around 3.7 to 4.2 for output voltage (Agreed). Over voltage can explode and he used bc547 whos output amp 100mah, thats not enough for charging faster.
@@user-wi8op3bf6l I can pity with your false or incomplete experience of the circuit or may be yours is a cooked comment.
Regarding the BC547: It is not supplying the charge current, that is handled by the relay. But I'm not sure how it can cut off. I will build it and try.
very impressive video
welcome bro..
perfectly done
Thank you bro..
@@homemade_101 welcome bro keep it up
Good 👍
Welcome
If I use a 12 volt relay, is that possible?
no
@101, The most lovely heart on my comment makes me to understand that you have not understood a single concept of my comment and so you have given me the Heart as if it is a Noble Prize. My Dear 1.01 I would love to get a considered reply including your suggestion if any otherwise consider yourself as an ignorant pseudo expert.
bc558 ट्रान्झिस्टर can use
Can't. Because BC558 is PNP transistor.
ПОЧЕМУ НЕТ ВИДЕО О ПОЛНОМ ЗАРЯДЕ И ОТКЛЮЧЕНИЕ ?

Battery Low side cutoff and full charge cutoff both side adjustable I need please halp me sir thanking you

Nice circuit. But no diagram.
have a description bro.
can i use 9v or 12v relay.pls reply.
Yes, but then it cannot be used for 3.7V batteries. 5V rails suitable for 3.7V.
@@homemade_101 thank u❤❤
ভাইয়া আপনি একটা সিকছ ভুলট বেটারী অটকাট চার্জার কিভাবে তৈরি করব তার একটা ভিডিও দেন
12 ?
can i use 6 volts relay?
can't 5V.
Cut off volt for littium 4.2 v you set 4.8 that's dangerous for littium may be blast ur cell
Can i charge 3.7v 3 batteries in series with this circuit
cant series connect but parall ok
Ok
Pls reply
Can i charge 4v led acid battery with this circuit?
cant
@@homemade_101 pls pls reply again
Why not? If i use a led acid battery charger and adjust it for reguired cut of voltage
CAN I USE 12VOLT RELAY?
yes it is 12v battery charger.
Cutt to laga hi nahi bhai cutt kese set kare
4.2v

Dear Sir, I want an automatic disconnect circuit for a 12-volt 75-amp battery. Thank you
try this one 👉th-cam.com/video/TftohNOGKQw/w-d-xo.html

Just remove the sound
How many batteries can be connected at once?
one
One of the bulb got burnt
why 🤔
I had put 5v input for a long time
