Oh my! This is what I need right now! I'm designing a project, and this video give me a good idea to solve a problem I couldn't make through. Thank you very much!
youtuber Indonesia, contoh ini video
penyajian visualnya sangat baik
pantas ditiru kalau ingin maju
As soon as I seen the title, I knew a LM3914 was going to be used. It is such a circuit in one DIP chip. Thumbs up!
Одно из лучших видео по diy, что я видел.
I like your images used to illustrate assembly - far better than watching a video of soldering only!
Soooooooo much beautiful project lovlyyyyy work
I like that stop motion..
GOOD TICHING KARTE HO AP 👍👌👍👌👍
Muito bom esses circuitos.

Great little projects... but on the 2nd one, the dude forgot to account for the voltage drop across the diodes ;)
this is just what i have been wanting to build thanks for the video ,now i do not need to reinvent the wheel .
thanks for explain
Excelente
Nice por
The 2nd has a good starting, but needs about 15v to lights up all the leds, and a battery has a max voltage of about 13v.
How can i improve the design to lights up all the leds at 12.6V?
What would be the value of the components to use?
muito bom.
Very nice sir
Thx friend!
Гениально!
Very useful
exelente
Very good
Subscribed....nice video...greetings from indonesia
love the visuals hnnnghh
Thank you bro
I think the 1st one is working great
Very nice
Thanks for very simple but useful circuit. 👍
BTW, what aplication used to edit your video? 🙄
Nice 👍🙂
Awesome bro
so cool thank you so much. i am new subscrber
Thanks and welcome ''
The best way to detect the Battery Voltage is with the LM3914. If you use this chip correctly, you can adjust the Range of the displayed Voltage. So you can set the Range from 0 to 12V but also from 6 to 12V, or 10 to 12V and so on.
But if you want a measuring Device with the smallest own Power-consumption you better use a Moving coil measuring device for the right Voltage with the proper precision Resistor for measuring range adjustment.
Интересно.

Nice video, thanks :)
thanks 🌹
Nice video
To all those people who apparently do not understand voltage, when a battery is dead, it has 0V as voltage is the measure of the electromotive force. In other words, if there is no charge, there is no voltage. So, yes, a battery CAN reach 0V.
But when a 12V battery becomes dead, it has about 10,5 volts. Get you some of that
@@joeybanana839 No it doesn't. If it did, it wouldn't be dead.
Nice reply
Tks brother
-gosto muito de eletronica
Отличное видео .Россия.
The background audio of this video is so 80s that I think I am watching an old film.😆
Very good. How to use for 12 / 24V batteries with 5 leds? Thank you
- The first example is nice to see how it works, but very bad as a battery metter, because a battery at 10v is dead and with 10v that metter have 4 lights on. Maybe changing the values of the resistances or/and adding another one at the input will work as expected.
- The 2nd has a good starting, but needs about 15v to lights up all the leds, and a battery has a max voltage of about 13v. Only has 14.4v as much while is charging. Same as above, but this time maybe the problem are the zener values.
For me, the best you can do is the third, because uses 10v as minimal voltage, and the max voltage can be regulated to lights up the green lights when is full charged (about 13v), and the white led while is charging for example (above 13v).
Actually, the battery would NOT be dead at 10V. A dead battery has NO VOLTAGE hence the term "dead". Also, the battery puts out 14.4V not when charging, but when it is being used to start the car. Thus, it does NOT have a maximum voltage of 13V.
@@protoborg At 10V is not dead but is worthless, you can not start the car with that voltage.
Also, unless the battery is deep discharge resistant with 10V is dying slowly.
Probably you will charge it again but the amount of energy that can store will be less and it get worse with every deep discharge.
Why did you say that the battery puts 14.4V at start?
As far I know it will have lower voltage no higher.
@@RDCST No it is NOT worthless. The car WILL start as it is not the charge that matters. It is the current flow that matters. Batteries have two different voltage readings. A car battery outputs AT 12V, but it doesn't STORE 12V the entire time. Thus a battery that HAS 10V is NOT useless. Further, modern batteries don't have any such thing as "deep discharge" as they are typically deep cycle batteries for safety and longevity. Deep discharge is not that bad. It doesn't actually start to suffer on the first deep discharge.
A car battery is rated at NOMINALLY 12V, but they generally run a bit above that.
@@protoborg are you a fucking idiot?
@@user-yw8sr3uj1w You're right. YOU are an idiot.
Very niCe
Does this in anyway work with a Lipo 2S? i wanna Check when both cells are at 3.4v so i have to charge the lipo. I wanna build it because i wanna build a 2S Pack for my Bicycle Lamps.
Good job my friend keep it up ❤❤❤❤❤
Thank you ∞
Quantos Amperes suporta?
Sepertinya saya harus mengukuti anda lebih jauh. Bukan hanya tentang pengetahuan yang anda berikan, tapi komentar positif dari banyak penonton.
super
❤️👍
Third is best... really.l
Ek hi value ke resister se ya different level indicate karega
Good job. What's the resistance value of each resistor in second model ...
Muito bom !
Tankyu boss
It should be called a Voltage indicator - not battery indicator. A 12V lead akku is empty when it reaches below 11.8V. To achieve this the first diode must be a Zener-Diode of 11V (or nearby). Multiple diodes also could be used, since each is 'loosing' around 0.7V.
How exactly would you get a voltage reading off a dead battery? Think before you speak. A dead battery will give a reading of 0V.
@@protoborg - You are referring to "Zero Volts" as "Dead", but if you read Lead Acid Battery Spec Sheets, you'll see the "Discharge Cut-off Voltage, is "10.5 Volts!"
Also, many Vehicle Circuits, require a Specific Minimum Voltage, ABOVE that "Cycle Test Cut-off Voltage, of 10.5V!
So, for systems operational requirements, saying 11.8V is equal to "Dead" may well be a reality, "In the System ", even though the batter still has Potential Energy in it! Just not enough to operate various systems or circuit elements!
Can u make RPM indikator with LED SMD , for motorbike 125cc ?!?!
ああっ、初めからメガネかけた白い鳥がーー笑笑
分かったら高評価！笑笑
can this be done with lm3900n and adjustable up to 17 volts with 5 leds?
Hi, The zener diode method results in surprisingly hi resolution for its simplicity. In theory I would consider 12.6V & up green for a rested lead acid car battery . While charging, green up to 13.8v, and then changing back to yellow up to 14.v, then amber at 14.6v, then red at 15v, for example. But that is my theory. might not be practical. You have done a great job I think.
I like your logic! Green for best "Nominal Voltages", changing the color shift towards Red, as you move out to the Extreme Ends, of Discharge or Overcharge!
Lm3914 is the best because it can be calibrated for whatever voltage you desire.
Secondly the bar/dot feature expands the confines of your design in the sense that you could light up the LEDs at higher voltages exclusively from the others
3:58the black cat gear music ahhhhhhhhhhhh swagggggggggggggggg
For simplicity and effectiveness, the #2 is better.
What model of camera do you use?
Hello...can we indicate more than 12v like 40 V or 54v or up to 84 V please tell me using same design...what modification required..please tell me
What happens when you try to charge your 12v battery ? Most chargers charge at 14v...
So, that means all the LEDs would be ON solid, yes ?
Should you add a 13v and 14v zener to show when charging is occurring ??

What's the name on the song used in 3:15? I really like that guitar part
how can we add Digital DC voltage meter.....in this diagram...to show the progressive charge value in voltages....hope to listen from you....Thanks Bro
In my opinion the first one was the most accurate
Vaiya ame akta 12volt cherger banai c.kintu ataptar onak grom /hit hoya jassa.akhon ame ki korbo.please help me
Sirji wich part need to change for 24v 20ah battery and wich is cheaper
I love this music more than your Diy indicator 😁
Need put micro relay switch with battery level for 18v and 20v Lithium ion battery but not cut-off, never empty, if empty battery then will be not good for dewalt, Milwaukee, makita and bosch lithium ion batteries, my home DIY i built more torchlights
Ok felicitar
thanx
Y aha bulb nu ki kehde
Eh kitho miln gee
Nice, I want a model of a 42 volt battery, what is the value of the resistance?
