Many issues that can happen. Without a BMC you will either overcharge or under charge the battery. Potentially burning the whole house or killing the battery.
Here is how you solve it: Calculate your "average" daily charges, like in Per Hour. Then use a "battery" accordingly. This way, the "battery" will "never" be over charged. NOTE: Also another big plus, if the battery gets drained at night or all usage. When it charge, it will never gets full, so you can't kill the battery.
The problem is that the video did not point out that the battery had a protection circuit so someone could use a unprotected lipo which would make the circuit dangerous.
There’s a lot of videos on here which show the diode soldered both ways, silver line pointing to solar panel as well as away from it, also some on positive rail and some on negative rail, which is correct? Please help
Shall you advise where to purchase online these items with links? 6v panel useful for this? shall you prepare for me with long extension wire for solar panel ? I will pay you
I'm kinda new to all this but how is the transistor base getting power if there is no solar. I dont get how the transistor opens up to let the light on.
Hi..I tried it as my home project for my child. The circuit is working but the light doesn't switchoff automatically when the solar panel is exposed to light. Can you please explain what could be the reason?
How this works ? It's an NPN transistor, so Base sgould get +ve for Transistor to work.But here it always gets -ve on the Base. Then how the Circuit is completing while there is no Solar energy ?
sir aapne jo 2025ic se amplifier banaya tha usme sound clear nhi aarha aur mai us video pe comment bhi kiya lekin aapne reply nhi kya please si us coment ko dekhiye please......request sir
In a couple of months, the battery will no longer give the same charge and in about 6 months, the battery will barely last on for an hour, all for not putting a bms for the battery, price : 0.25 cents
Very nice !! But you forgot to mention that you must use a battery with a protection circuit. Like an old phone battery.
I did it with the s9014 transistor. it worked. thank you.
Nicely done. I love its simplicity !
Super Video Sir Amazing
WoW it's really awesome
I am Electronics student sir you are awesome
😍😍😍😍😍°°° ••• °°°° ••••
Thanks
Thanks Sir for your video n i'am get study in home... I'am your subcriber n peace from Indonesia...
Thankyou***
Wah bhai👍👍.... Kya hm 3v ka led bulb bhi use kar sakte he

Look before you leap, it looks like the cell has a protection circuit, although there is no blocking diode for charging and night discharge
The problem is that the video did not point out that the battery had a protection circuit so someone could use a unprotected lipo which would make the circuit dangerous.
Good job. You should come to mexico we can make great projects together
As u have used 2n2222 instead of that can we we use 4056 or any other as we are using 3.7 22000 mah 18650 battery
If I want to use a 1.5 A and 3.7V lighting, which transistor do you recommend?
There’s a lot of videos on here which show the diode soldered both ways, silver line pointing to solar panel as well as away from it, also some on positive rail and some on negative rail, which is correct? Please help

Muito bom obrigado! joão from Brazil
Resistance 22k ohm ka lava sakte h kya reply jaldi dena
Hello my friend..you did good job. hope some day you make solar panel using TP4056 charger board.thank you i sup
RJ sir, please give us a proper guiding reply about battery protection, is if it available on this circuit...?
No cell protection in this circuit

Hello can you make a video and schema of the circuit with 12 volt please?
The automatic off and on will work without diode? Only use transistor?
How....
Does work with 5v panel? 🤔
Bhai Agar Main transistor BC 548 lagaunga to chalega kya
Sir only Tranaister se chalega diod aur resister ka kya kaam hain
Hi rj plz tell us about Metal or detector
Okay
Shall you advise where to purchase online these items with links? 6v panel useful for this? shall you prepare for me with long extension wire for solar panel ? I will pay you
Will it work with 6V solar panel ????
you did Good job I have a question about whether I can use a battery with 18650 Thanks
Well working.
But light is not much glowing,
Battery is full charged
12v solar panel and 12volt ke battery ke sath ye work krega
i build it too. works great. thx
Can i use a lead battery from an old lantern ?
I'm kinda new to all this but how is the transistor base getting power if there is no solar. I dont get how the transistor opens up to let the light on.
it will work for a torch light no . please reply.
me imagino que la batería que usaste tiene protección, por que si no el exceso de carga la dañaría
sir maine aisa hi kiya h lekin led dim jalrahi h direct battry se lagai to full jalti hai
pls help me
Hey ,it was a asom video I ever seen and also simple.but can this project run over night
CAN I USE BC 547? PLEASEE HELP ME

Bro, if I use with out 10k resistance, or use 1k resistance, any problem is happen is came or not tell
Is the 1n4007 a protective blocking diode?
not at all
Very nice bai apne to meri problem ko hi solve kar diya thanks
Thankyou sir
Very useful video
Question. How long does the light last?
Battery charge khatam nahi hoga kya
How long does it resist light full night or not
Will the day charge of solar pannel to batteries ,can cause damage the battery life or not..??
It definitely can damage battery so you could consider adding another transistor and capacitor to your circuit
Mais um vídeo show 👏
Hi..I tried it as my home project for my child. The circuit is working but the light doesn't switchoff automatically when the solar panel is exposed to light. Can you please explain what could be the reason?
100k ohm resistor chalega sar
can I also take bc547 from 2n2222 transistors?
Yes
You really cannot
@@johnsajith why???plz explain
How to use it for 12v solor panel
whether the battery is charged
Hi,
LED turns off only if the solar panel is in direct contact with the sun
It's working, but light dim.
I have same problem i solve it.. change transistor left to right..it will help
I changed solar panel, now ok
1. Is 10 k resistance also positive or negative ?
2. If yes then which side connection on solars nagative point
Resistors are not polarized. So question 1: no
@@Peter_A1466 yuh cuz it’s resistive on both sides, the wire just loops
How many hours does it last at night?
İ want brighter , what can i do for it ?
Decrease the value of resistor
@@RJImagination i did it bro, i used 5k but nothing changes is there any other resistor i can use ?
It's very good. Thank you.
Bhai Ki Char Balak Lagane Ghar Ke Chalu prapt kaise hoga
i just wonder how long will the light last at night?
How this works ? It's an NPN transistor, so Base sgould get +ve for Transistor to work.But here it always gets -ve on the Base. Then how the Circuit is completing while there is no Solar energy ?
Why to use 10k resistance ths project? ??
Agar 12volt ka strip light lagane se kam krega
Он не взорвётся ? Не разрядится ?
Did it explode battery ?
Sir Ye trnasister to laga diya
Aur Didod resiater agar Nahi Lahaya to Chalega replay jald dena
Output voltage drops from 3.7v to 2.55v. What can I do?
Bro Can i use 1k resistor instead of 10k?
how it run with power bank, sir?

need stabilization 4.2 volts for li-ion battery.
In a couple of months, the battery will no longer give the same charge and in about 6 months, the battery will barely last on for an hour, all for not putting a bms for the battery, price : 0.25 cents
Ye charge kaisa hoga
what can that do?
This circuit will works to 6volt solar panel also
I don't know if it still works for you, but if it can, I made the same circuit but with the 6V panel
how mach volt end watt you solar cell
Please explain the theory of this circuit
Bro background music name please
If we put on off switch then
Aur bc 548 chalega sar
used 4v battery?
I used a 3.7 which is close enough.
Si funciona bien 👍
Good
