This is the correct principle to charge a 4v dc battery. The capacitive dropper ckt will not reduce the voltage but it will reduces the current, the voltmeter shows the voltage of the battery in it. But before connecting the battery as load the output voltage should not be more than 5v which is never possible with the capacitive dropper ckt and if possible it would not be so much economical.
received 4.46v with 520ohm resistor (if suppose that my cheap dt838 quite precise😁). By the way : my diod doesnt light during charging🤔 Is it critical? How to add overcharge protection now?

approx how much time will it take to get charged? can tell?

Idk what is positive and negative can I connect it in opposite way
I think adding 100E 1,W resistor is safe .
How much time it takes for full charge
Can we add Capacitor with this circuit for more protection to the battery?
Will this circuit supports overcharged protection?
Nice Can make Battery Overcharged Protection Kit
Really grateful for projects maker, you r cool brro
You haven't answered or mentioned about the charging time required for the battery, much needed answer from the channel
What is the current which is given by the charger (is it less than 1ah?)
0.5 ah
i have 4v 2.0 ah lead acid battery
can i charge 5v 550mah mobile charger
yep
Bhai kaise pata chalega ki full charge hogya hs
Kya is cercute main battery over charge. Nahi hoga

How to add overcharge protection now?
Dose 6 volts battary work.....?
Work
How many time required to full charge
30 - 60 minutes
Bhai lithnum battry ka liya bhi sahi hai ya
Bhai bata dena plz
You are the best power gen
Solar me 10 watt loom solar me ye chla ga plz bta do 5 volt plz
Kya hum isme 3.7 volt ki do battery ek sath laga sakte he
Yup
After charging the light will off or it will be on
it will remain on as long as the power supply is connected
can i use diode 1n4002 instead? it happens that i have those
You can use any diode which has a voltage drop of exact 0.8v or atleast around it
Bai micro USB. Kese perches kare ake pine bai jo apene video me dhikayatha ake kat cable KO kese caridhe
4.5v is fine too?
Diode कितनाvolt का है जल्दी बताओ
Very nice
4 volt battery ko kitna der tak charge dena chaye
battery ka charging ampere ko charger ki ampere se divide kijiye answer jo hota hay wahi hay battery charging time
Can we use 450 ohm resistor in places of 470 ohm resistor
U can use 1k resistance
Absolutely yes
can we charge 2same batteries with one charger plz make video on that
this circuit enough you for 2 battery but charging time extra taking
Very nice 👍
Super bro explained very well with diagram
Can we do it with lithium battery charging module
yes
After charging how to use it for light
How can i get 1N4007DIODE and 470ohm resistor? pleas reply!
Just vjsit electronics ic market easily available in₹10-15
I know! But i want to ask that from old things like led lights etc.?
@@euealtewodros885 almost in every circuit, led as welll
What ?
Example like
maibhi banaliya batane ke liye thank you
Kitne time me charge hogi
Approximately
2 to 3 hours
Can i charge lithum polymer battery
NO. Unless you add some current limiter (resistor is enough) the battery will pull too much current which it won't handle.
Don't do it anyways. They always blow up
Resistor कितनेvolt का है
These is no voltage for resistors
Ye micro usb interface kha milega
Why that diode is used?
Battery charge ho gayi hai ye kaise paatha challenge?
How many hours we charge
30 min
Really you are great
This is working
Want to charge this with a 6v3A solar then
you can use the dc-dc buck converter (6v to 4v)
@@powergen522 can u please explain and send me a circuit board diagram
Ok sir
I will upload video with block diagram
You have not attach it button.
Bhai ye battery kharab to nahi karega
i honsetly use a wireless controller circut to charge all my batteries so they dont blow up in my face
Diode is getting too hot during charging. Why
Charger 550 mah se jyadWala hoga toh diode heated
Hii ,
I have used in4007s diode , quad watt resistor , but not charging the battery
check the components
Bro pls explain me how to connect lead acid battery with mobile charger to dpdt slide switch
Thanks bhaiya
Charging jac kaha milta hai
Can I use 2 amp charger
What a project man!!
why we have to use diode?
So that the led doesn't drain the current from battery in the absence of charging voltage.
Bhai nahi laga lagaya ta
Best learning video
Thanks
Super
I can try this
Good job
Very well
Bhai yei bilkol kam kartahey
wooohooooo!
Bro diod is too hot why
is no
Ganato gao.
👌😱
Hai bro one sub.. Please
fake vidio
Pagal hai kya
Sup bro
💡👍
Electric kaj korte Amer valo lage.
Nice
