In this video I'm showing that how you can make easy 3.7v battery level indicator circuit at home with few components.
Just need...
4x leds (2x Red, 1x Yellow, 1x Green).
3x 1N4007 Rectifier Diodes.
2x 220 ohms Resistors.
2x 47 ohms Resistors.

Nice and easy useful project 👌👌👍

[@CreativeTechos]

Thankyou

[@MultiPlaymaker10]

Hi. Would you mind explain why you use 220r and 47r resistors? Why not all same value? Thank you

it is better to use leds of the same color.

Hello sir I am tasin your video is great thanks for your video

[@CreativeTechos]

Thanks for appreciating, you may checkout my other videos

[@veeem3964]

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

[@CreativeTechos]

Yes, i will soon upload video of adjustable battery level indicator for any battery.

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

Why are both red leds using different resistor values? Whats the purpose of alternatimg values?

[@ahmetmutlu348]

good one if it works. but i think we can use some small resistors there instead diodes which mostlikely are acting as resistors

[@CreativeTechos]

Nope you can't use Resistors, as diodes there is to drop voltage while blocking reverse voltage

[@ahmetmutlu348]

@@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 ?.

[@jimfalls8671]

The diodes are used as Zeners, but they have a handy lower forward voltage you have to exceed before they conduct.

[@ahmetmutlu348]

@@jimfalls8671 that seems like undocumented feature of dioddes.

[@jayantanath9]

can this circuit be connected with automatic cuto off if lm358 after connecting it will it act like power bank circuit blinking while charging

[@CreativeTechos]

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.

[@bhatrufaidah847]

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

[@CreativeTechos]

Cannot be made with this circuit, since led itself glows @ 2.2-3.2v

[@powerROBY]

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

[@applereyresurrecion6428]

Please show how to make battery indicator for 3v only sir? Think you

[@CreativeTechos]

For what 3v thing you need?

[@applereyresurrecion6428]

@@CreativeTechos 3.2v for lithium battery indicator.

[@CreativeTechos]

Usually lithium batteries are rated @ 3.7v and full charge voltage 4.2v

[@applereyresurrecion6428]

[@techhub8419]

Any color LED can be used?

[@vivekdhapkaree2623]

Yes bro

[@CreativeTechos]

Yes you can use any colour LED

[@orangeshaw2370]

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.

[@udayram9856]

How it will connect with battery charger?

[@paneerpolice3454]

how much current did these led draw?

[@CreativeTechos]

Each led is rated 20ma
But in the above circuit it will draw less

[@darshanhegde1709]

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.

[@kuro758]

connect this circuit directly to the battery.

[@CreativeTechos]

Yes, connect directly

[@jantube358]

Calculate different resistors so the 25% LED glows at a different voltage

[@JesusLopez-fi1yq]

How could I do that for 2S 18650 batteries?

[@CreativeTechos]

You can add 2-3 more leds in series as 2s will have full charge voltage upto 8-8.2v

[@Juniorfinger999]

Indikator cek out or cek condition battery ?
