- 12v battery charger.
12v auto catt off circuit.
Components:
- BC547 transistor
- 2 LEDs (red and green)
- 10k resistor
- 5V relay
- 1N4007 diode
- 1k resistor
Circuit Functionality:
- The circuit monitors the battery voltage and automatically cuts off the power when it falls below a certain threshold.
- The red LED indicates low battery voltage, while the green LED indicates normal battery voltage.
- The 5V relay switches off when the battery voltage falls below the threshold, disconnecting the load from the battery.
- The 1N4007 diode protects the transistor from back-EMF.
- The 1k resistor limits the base current of the transistor.
How it works:
1. The battery voltage is monitored through a voltage divider network.
2. When the battery voltage falls below the threshold, the transistor turns on.
3. The red LED lights up, indicating low battery voltage.
4. The 5V relay switches off, disconnecting the load from the battery.
5. When the battery voltage returns to normal, the transistor turns off, and the green LED lights up.

It is possible to explain a little if more than one stone in a row at the highest voltage
yeh circuit kitne amp tak ka battery charge kar sakta hai. max charging current kitna de sakta hai yeh NAHI bataya is vdo mei.
800mA
10 inch ke speaker ko chalane ke liye emplifier banaen
Bhai 12v ka relay use kar sakte hai
Nahi, 4.2v battery ka charger banana hai to 5/6 v. Ka relay use karna padega.
Ok thanks
Sir can i use this circuit for 3.7V 100A Battery? and auto cut it?
No, 100Amp is too much for this circuit.
Bhai maine 6volt rely ka circuit banaya h same pr o awaz krta h beep jaisa to koi acha circuit batao jo thik se work krta ho bhai
Input voltage kitna dia? 6v se upar doge to awaj karega, ya fir battery ka connection ulta doge to, charging circuit mane ak banaya hai use vi istemal kar sakte ho, channel per hai, mai jaldi ak or vedio bana dunga.
@@ElectricDhamaka bhai o to thik h pr 6 volt battery charging circuit bnd ho aur 6 volt rely circuit ko ager batery connect krte h to red light jlta h aur beep ki awaz ati h circuit bateery se connect krte hi kharb ho jata h bina bsteery charging circuit bnd bhi ho to esa koi solution h bhi ya nhi h
Please will the input voltage reduce when the battery is connected at the output, and then slowly rise up to the disconnect voltage?
Yes this cercit work like this.
Auto cut set karne ki jarurat nahi hai sar
Battery over charge hoke kharab ho jayega isliye
can i use 20k preset instead of 10k
pls. tell me
Yes you can
Nice 👌
What is the input voltage
5v-4.99v
Can i use 100k pot, or 20k
You can Use 20k pot , but 100k is much higher resistance for this project.
@@ElectricDhamaka thanks, can i made this without pot?
Yes you can
But you have to calculate the resistance value
@@ElectricDhamaka yeess, i didnt think about it.
Can it work on 5v for one battery
Yes it is made for 3.7-5v battery
@@ElectricDhamaka just one question, can i use another transistor and please tell me which
yes you can use any type of NPN transistor and also PNP transistor but if you use PNP transistor then circuit diagram is not same as I made this in this video. I am using bc547 transistor in this vedio.
@@ElectricDhamaka wow, thanks bro so much
Sir cutout 4.20v may hona chahiye na..
Kiwki battery full charge voltage tho 4.20 v hay na.🤔
can this circuit use to charge mobile phones or electronic devices that have batteries?
Yes it can, but don't use because sometimes Relay doesn't work . This is just diy project, you can charge car battery or open li ion battery Which do not come with a separate protection circuit.
Pahle charging on kar ke bad mein battery laga ki dikhao
Acha tho ye cut out kithny volt par hoga? Or kesy full charge hony par satting karengy
10k pot ko ghumakar
Me eksath 3 battery charge kr sktw hu kya
Lion ki
3600 per battery almost
10,800 mah ka pqck charge kr skta hu y nhi ?
I need to charge 7.5v battery how to do that relay which I have to take
Same cercit but use 6v relay, i will explain in my next video .
Sir kitne voltage mey cutout huya.
Or ky battery ko full charge kar ke preset set kar na parta hay
4.2v , haan,ye app manually set kar sakte hai,
What is the position of Diode which the anode and cathode
Kya hum choti BLDC motor ko ghuma kar phone📱 ko charge🔋 kar saktey🕉️ hain🕉️
voltage rectification circuit chahie uske liye, usmein three phase AC voltage aata hai.
@@ElectricDhamaka karo??
Ok
Good evening, it takes about any charge, thank you
Relay la kontya wires connect kelet green and blue crimp pins ahet tya
Can I use 6v relay?
Yes
good video
