Very nice and simple circuit it works well for 3.7 volt battery. Can this circuit be connected to a device that is being charged to show the level of charge like a charging monitor.Can you please post a level indicator for 5 volts cell phone and also for 12 volt batteries Please reply with circuit diagrams Thanks
No, it is ideal to use push button between battery & this circuit, and press button whenever you would like to check battery level. I'll soon upload video of battery level indicator with auto cutoff charging.
hello I would need a lot to do such a thing for a 16.8 volt 4S battery pack, I need it starts from 10 volts up to 16.8 volts ... can you help me understand how to do it? thank you
Each colour LEDs have a different voltage threshold, eg.for same intensity tweaking Red LED needs lower voltage than purple LED, BUT in "general" it doesn't make much difference.
@@CreativeTechos but the leds allready acting as resistors. so their work seems like doing partial resistance by lossing lots of power while doing their job ?.

Hi. Would you mind explain why you use 220r and 47r resistors? Why not all same value? Thank you
@@attilarivera
it is better to use leds of the same color.
Nice lithium cells charger indicator thank for this information
Thanks 😊
Well done explicated, good teacher
Thanks for watching my friend 🙂
NICE & USEFUL VEDEO 🙏
Este esquema parece ser muito bom; mas será necessário o uso dos 3 diodos in4007.
Saudações de Portugal.
Vai, Corinthians!!!!
Yes because it will drop little voltage to glow leds step by step
good circuit and simple to make. LEDs of the same color must be used.
Hello sir I am tasin your video is great thanks for your video
Thanks for appreciating, you may checkout my other videos
👏✊👍Awesome this cercuit working perfect Weldon
Thanks for watching 🙂
Thanks a lot, from Brussels !

Please reply with circuit diagrams
Thanks
Yes, i will soon upload video of adjustable battery level indicator for any battery.
@@CreativeTechos Its Kiloohm or Ohm?
Ohms
It is a perfect video unbelievable
Thanks for appreciating
can this circuit be connected with automatic cuto off if lm358 after connecting it will it act like power bank circuit blinking while charging

What is difference between red led and yellow green ones ?
Indikator cek out or cek condition battery ?
Sir If we have to use it for 2.2v or 1.5 v battery then what are the changes we have to make in circuit
Cannot be made with this circuit, since led itself glows @ 2.2-3.2v
Muito bom parabéns
Thanks for watching 🙂
Perfect as always ❤️
How it will connect with battery charger?

Thanks Good video sir❤👌👌
Most welcome sir
how much current did these led draw?
Each led is rated 20ma
But in the above circuit it will draw less
Thanx bro
Any color LED can be used?
Yes bro
Yes you can use any colour LED
Each colour LEDs have a different voltage threshold,
eg.for same intensity tweaking Red LED needs lower voltage than purple LED,
BUT in "general" it doesn't make much difference.
good one if it works. but i think we can use some small resistors there instead diodes which mostlikely are acting as resistors
Nope you can't use Resistors, as diodes there is to drop voltage while blocking reverse voltage
@@CreativeTechos but the leds allready acting as resistors. so their work seems like doing partial resistance by lossing lots of power while doing their job ?.
The diodes are used as Zeners, but they have a handy lower forward voltage you have to exceed before they conduct.
@@jimfalls8671 that seems like undocumented feature of dioddes.
amazing bro, can you make with more led, example with 10 leds ?
Yes, I'm soon going to upload with ready PCB.
You make with simple komponen and very cheap, and it work, i like it, next i hope you make with 10 led with same to
mạch bảo vệ 👏👍
FUNIONA PUREX BATTERIE 6 12 E 24V?
I make it it work
Please show how to make battery indicator for 3v only sir? Think you
For what 3v thing you need?
@@CreativeTechos 3.2v for lithium battery indicator.
Usually lithium batteries are rated @ 3.7v and full charge voltage 4.2v
@@CreativeTechos ahh okey thank you
How could I do that for 2S 18650 batteries?
You can add 2-3 more leds in series as 2s will have full charge voltage upto 8-8.2v
Hi, if we use BMS then low cutoff threshold is 3.2v or something then how to show it as 25%? Can you please suggest what to be done.
connect this circuit directly to the battery.
Yes, connect directly
Calculate different resistors so the 25% LED glows at a different voltage
Machines take my hade works.😊😊😊
Excellent 👍🇵🇰
Thanks for watching my friend 🙂
Thank you ....
Most welcome
Great
Thanks for watching my friend 🙂
LED 3v ?
Each colour comes with different voltages, red 2.2, yellow 3 green 3.2
thanks🙋♂️
My pleasure, sorry for late reply, it was missed due to bugs in YT Studio
Good luck
