New Type 12 volt battery level indicator.
[ Shows battery status from 10-13 volts ]

[curtc]

This would work as a capacitor charge indicator, but battery charge is not linear with voltage. A 12V battery would essentially be fully discharged when your circuit indicated 80%

[aftabmaqsood]

But battery are of no use below 10.5 volt which is like 5% left

I spent a couple of days searching for a kit, and now I don’t need a kit ! 😎👍 I have everything already.

Good idea but it should be noted that the voltage of a battery is only meaningful if the battery is under load I.e. being used. Measuring a battery float voltage (I.e. not connected to anything, ) means nothing about battery condition. It could give you a reading of 12v but immediately drop to under 9v when you connect it to the item it is powering especially if it is a motor or a globe for example. Have your nice meter connected to the battery while it is connected to what ever device it is powering and it will give a more accurate reflection of the state of the battery while being used. Just my comment. Otherwise thanks for sharing the circuit.

Glad you showed schematic. Most YouTubers don''t show schematic which means that they just care about manufacturing/soldering and not engineering.

[shahzaibmajid]

Thanks its nice and I'm locking that type of level
Finally i got it
I'm making a project thats thing solve mey problem by 50% of my project
Thanks

you show us everything without hiding anything from us to realize your projects, you seem to me a good person, you are the best

[Simon-qnwm]

Nice simple & very useful circuit, thank you

[eeghtitelukintan]

as new in content creator, i'm very impress your project

[squadgamingz]

Bahut bahut shukriya Bhai.
Video Bahut acchi hai.

[AnilKumar-tdjz]

Very good information....Thank u very much

[aoyuki]

this is a really interesting project and a cool example to show voltage dividers, but one crucial point is that this cannot be 100% accurate if you use 20%, 40%, 60%, 80%, 100% linear scale.


this is because typically red LEDs have 1.7-2.0V drop and blue LEDs have 3.0-3.3V drop so you either have to use six to seven reds, or four to five blues to use linear scale

[enriqueatala]

Very good and useful, thank you, I will use LEDs of a few millimeters to put everything in a pen... greetings mr.

[polarultra]

The accuracy of this indicator is about the same as aiming rubble at a target. The design itself is cool because it is simple and works, but as a charge indicator it is not suitable.

Proyek sederhana yang bagus, Trimakasih saya akan membuatnya untuk aplikasi batre dirumah👍

[giannhs]

work my friend i test my house thank you

[bangjaka]

Wow, this is very useful, thanks for the idea, I need to try this.

[pauljanssen]

Basically when a 12-volt battery drops down to 12.1 or 12.2 it's on the very low side 12.6 it's fully charged it's just matter designing one with right resistors the right voltage you desire red for overcharging green for good yellow on the low side red when you're at 12 volts.

[Serafin]

This simple and easy to do project, well explicated as usually, with transistor free. Thanks
