Very nice use of diode forward biased voltage, such a nice and clean working circuit, i was shocked after testing this amazing circuit on breadboard, thanks a lot for the inventor.
hey thanks for the video what if I am only interested in just 1 led .. which shows that the battery is 4 volts charged .. could you please help me ... I am charging one 18650 cell and I just want to glow an led when the battery is 4 volts charged(or towards 100% or 95%) .. could you please help me ..
@@Electronic_For_You even as an indicator it does not work for me bro, your sample video does not show the whole wiring package while testing, some wires are not visible show the whole thing connected to a battery...
@@16BITMEME yes there's a color code but sometimes it's tricky if the up loader does not show the whole thing,, same color but connected to a different gadget so we need to be transparent , there's lots of Magician on youtube
It is not OK. At 4.2 V, all 4 LEDs should have been on. At 3.5 - 3.6 V, just 1 led. Below 3.5 V, it doesn't have to illuminate any LED light . The Li-ion battery is destroyed if the voltage drops below 3.2 V .
Connect a 10k pot at + And adjust the potentiometer until all led lead up at 14.8V ... That should work..I think And add a push button to stop draining the battery when you need just push and see Thanks for watching Have nice day
@@Electronic_For_You no! me need indicator where^ 1 red = 3.6 2 red = 3.8 2 red + 1 green = 4.0 2 red + 2 green = 4.2 on you multimeter i look another(!): 1 diod = 3.7 2 doid = 4.2

Glad you liked it
But a nice Elektrotechnik 👍
Thank You 😊
Just what I was looking for. Ur awesome imma sub

The last green led is positive solderd to the copper wire or negative not mentioned.
All LEDs are connected same way....!
Sorry about that
Please follow the video
@@Electronic_For_You Thank you

You can try by skipping LEDs
@@Electronic_For_You : so .. if i ignore 3 leds .. can i also ignore the 3 resistors ..?
@@Electronic_For_You : ohkay thanks .. will try it ..

И желательно этот индикатор подключить без отключения и будет отличный помощник в разряде батареи.
Yeas
You should connect a Push button to it so when you need to see the parsentige push and see ......
You are right it will discharge the battery
Nice 👍
Thanks
👍👍👍👍👍
Really creator👏👍👍
Thanks
Top, muito bom
🥰
Any diode 1n400* can do same,that voltage drop when they are connected in series, can also be an indicator for 3 v (2x1,5v)etc ...
Yeas
Tq bhai
Very nice ! I want to make this for 8.4 volt 2s lithium ion battery. What value should be change? Please help ! Thanks in advance :)
Add more 4 leds total 8 leds
Bro what are you using instead of soldering helping hand but the video is very good
Thanks
I'm using Paperclip.....!
Good
Thanks 😊
Hi sir, what can I do if I need only a maximum of 3.77 volts? Thanks
Remove diodes of upper Led
😍😱😱😱WOWS BANGLADESH

U can make like this circuit for 12v.
Ok 🙂
Hy bro please make inducție heater
Already Meked bro :D
Creatif guys,,
good video
♥️
bhai isko hameha laga ke rakhenge to bettery khatam to nahi hoga na plz reply
Use a push Switch at + terminal when need to see the voltage just short press
Can we add 220 ohms instead of 100 ohms, thanks bro
🤔
I Think it will work ...!
What is your input voltage ? because this circuit does not work with 5vdc input to charge a 3.7v battery
Oh no
This is not A Charger for battery This Is a Indicator which show how much charge left in your battery
You are thinking wrong
@@Electronic_For_You even as an indicator it does not work for me bro, your sample video does not show the whole wiring package while testing, some wires are not visible show the whole thing connected to a battery...

Welcome
But use a Push button in series with it so . it doesnt turned on full time
Para una pila de 6 volt que nececito cambiar
I did not understand your language
@@Electronic_For_You he or she is asking that for a 6 volt battery I need to change
Bhai description me jada hashtag (#) mat lagao warna RUclips app ke channel ko terminate kar dega
(Very important)
No bro
You can add 15 hash tag ....!
Can i use 1k resistance instead of 200 Ohm?
🤔 no maybe it will not work
Hi can I use the circuit for two batteries as such?
Yeas
then you need to connect 2 same circuit in series for 7.2V and 3 for 13V
It is not OK.
At 4.2 V, all 4 LEDs should have been on.
At 3.5 - 3.6 V, just 1 led.
Below 3.5 V, it doesn't have to illuminate any LED light .
The Li-ion battery is destroyed if the voltage drops below 3.2 V .
It works from 3.8V to 4.2V
I showed in video
@@Electronic_For_You Yes. I saw !
But it is not normal to work, any LEDs under 3.5 V .
If it does not light any led that mean the voltage is under 3V. It ligh up 1 led at 3.8V low charge and all 4 led shuld light up at 4.2V
@@Electronic_For_You please, what if I want the first LED light up at 2.5v?, That is exactly what my project requires. 👍
Frist led will light at 3V
Can i use yellow led instead of red? And can i use all green leds?
Yeas But
Use same Size.....!
Nyaa
Can you make it for lifepo4 battery?
You need to decrease Diodes

Bro eske sath charger kaise connect Kare........
Use Charging Module
Can I use for 12v
It will not work
Why we are using diode here?
Because
Diode has a voltage drop 0.7V and we are using them to see how much voltage left on battery
А на 1.2 вольт как расчитать ?
Please can you tell me in english?
@@Electronic_For_You he is asking how to calculate 1.2 volts
Calculate?
@@Electronic_For_You Да попробуйте расчитать для 1.2V NIMH аккумулятора . Yes try to calculate for a 1.2V NIMH battery. :)
Oh you want to charge Ni-Mah battery?
🤔 BUT AT 1.2v led will not work they need 2.5V but if you use 4 battery in series then it will work
Dear what will be the resistance value for 14.8 volts indicator
Connect a 10k pot at +
And adjust the potentiometer until all led lead up at 14.8V ... That should work..I think
And add a push button to stop draining the battery when you need just push and see
Thanks for watching
Have nice day
@@Electronic_For_You so, when all leds is light meter the pote and then put an resitance of same value. can this help you
all my leds bright at same intensiti xD
Where can we connect 5v dc battery charger + and - ?

It's should be 3.7 to 4.2 not starting from 2v
Last 2 red led means low charge!

No
It measure voltage
From 3.7V to 4.2V

Green resistance 🤔
what is that?

Right....!
Go and buy one
NOT from 3.7V To 4.2V
this is indicator from 2 to 4.2 volt
Yeas Red mean low charge .
@@Electronic_For_You
what create this? scheme:
1 red = 3.6V
2 red = 3.8V
2 red + 1 green = 4.0V
2 red + 2 green = 4.2V
You can see I'm showing the voltage on multimeter 😊
@@Electronic_For_You
no!
me need indicator where^
1 red = 3.6
2 red = 3.8
2 red + 1 green = 4.0
2 red + 2 green = 4.2
on you multimeter i look another(!):
1 diod = 3.7
2 doid = 4.2
You need to use zener diode
This is lier i do it but night are working by diod
What 🙂
It doesn’t work
It works 🙂
Faick video hain na
Did you tryed this ?
