12/24 Volt Battery Level Charging Indicator

12/24 Volt Battery Level Charging Indicator
This is very cool project for make a simple battery level indicator for 12/24 volt battery. You can control voltage depending on battery. Also you can make auto cut battery charger using this project.

I love 'how to' videos that just show you without any spoken word. somehow they are so much more efficient at teaching the subject matter.

[@EPaulIII]

That is NOT a charge level indicator. It is a Voltage indicator. And the relationship between the amount of charge and the Voltage of a battery is NOT linear. This type is indicator is widely used and it shows a good charge until the battery is about 90 to 95 percent discharged. Then, it rapidly goes down the Voltage steps as indicated by the LEDs for that remaining 5 or 10 percent of the full charge. You are mislead into thinking your battery is just fine when it is really about to die on you very quickly. In this day of PIC style processors, we should be able to build a $10 circuit that actually keeps track of the actual CHARGE that is left on a battery. But with trash circuits like this around, no one is doing so. As for those who are asking for a circuit diagram, look in a 30 or 40 year old LINEAR IC spec book by National Semi or TI or any of a number of others. This is NOT a new circuit. In fact, the IC used may already be obsolete and difficult to get. I played with them decades ago.

[@me163bkomet]

Interesting data, have you any book reference in specific?

[@Den_Electro]

that's right

[@waltercomunello121]

That solder tip is really filthy. You might want to clean it. Really awesome and neat handwork though. Solder traces look really good.

[@mcintosh479]

why dont you try to sell these kits on ebay or amazon or tell me how to get one, also i need to install this in my car 12 v auto battery charger..the original meter has melted, you could sell alot of them because the meters in the chargers never work

[@fpvrcstuff]

Where did you use the 1K Resistor in this Circuit, I must have missed where you used it ?

[@powerROBY]

hello I would need a lot to do something like this with 5 LEDs for a 16.8 volt 4S battery pack, I need it starts from 10 volts up to 16.8 volts ... can you help me figure out how to do it? thank you

[@ginreyandaya8889]

Good day sir, what kind/size of wire are you using? I'm talking about the wires that you've used in your circuit and the one that is used for connecting to the power source thanks

[@asuscalen9905]

hallo and thanks.... in your diagram .. there is 18k resistor .. but in video subtitle wrote 1k .... and i Replaced 56k resistor to another value to work good...thanks again

[@uttammajumder1008]

Good job. I like it. Many many thanks .

[@easytechzones]

Welcome

Wow. Multicolored bar LED is a new for me

[@bigcreoman]

Hello dear! Can I make this to 0-24v indicate? I have LM3914N with leds on the board already (looking for the solution).

[@bigfanpavan3988]

bro! can you use same IC and LED for water level indicator with buzzer and power adaptor ? if so can you please show how to make it... once done can you please sell it to me.

[@easytechzones]

No

[@archaosvlogs5914]

May I know what is the orange wire thingy you putted?

[@iblesbosuok]

Applying LM3914 directly to LED will make LM3914 gets very hot. It is better to insert series resistors to each LED Greetings from Indonesia

[@владимирякимов-з2ц]

Это ж надо было так насрать на плате😤

[@promitdas4057]

Will it work for 5v battery indicator?

[@asadnawaz4697]

Sir apne jo light use ki hai ham uski jaga led light use kar sakten hai keya plz tel me or led light ke sat kise chiz ki changing to nahi karni hoge na

[@AashishSharma1975]

Can we use different numbered 16 pin IC?

[@shilohperilla866]

Can this be used as voltage meter 1.25v to 15v? If not can you make video on how to make a voltage meter using this led bar?

[@crimznn17]

How do you check that it is currently charging not necessarily the level simply if it is charging or not

[@nikhildarkunde9867]

Nice

[@easytechzones]

Thankyou

[@nikhildarkunde9867]

Please make video for 60v or customized voltage

[@easytechzones]

Ok

[@BuluBuridSMDA]

I have a unit led bar from old broken PSU, but it only have 8 bar.. Can I use that 8 led bar with this schematic ??

Can i set in lower voltage like 2.5v to 3.7 for battery indicator of lithium battery?.

[@holyshit2709]

Awesome build. Thanks.

[@sitenderantil7470]

Can i use this circuit for 12v/200amp battery.

[@pawebartocha6604]

[@ArdiNugrohocilacap]

nice

[@Beysis]

Good job ...Stable circuit Awesome!

[@NAVEENpanghal27]

Sir can it be used on my inverter battery to display the voltage continuously.. (for 24 hrs) ? Is this I.C. Capable of performing for so long.. please reply

[@NAVEENpanghal27]

Sir i tried making it without a switch but whole light bar is lighting red at all voltage conditions. Using a switch is compulsory? what is the specification for this dot/graph switch. I’ve bought a spst switch (one way), it will work or not ? Please guide sir.

[@zerodegree4471]

what is Dot/graph ?

[@soumyapalkundu7387]

plz tell me what is the function of the preset in this circuit? and what is s1 in the diagram? is it switch?

[@MADxHAWK]

With the preset you set the voltage when last LED will light up (battery fully loaded) So you can adjust the circuit for use with 12 or 24v bateries for example by adjusting the variable resistor. With S1 you can change between Bar (graph) and Single Led (dot) display. You can use a switch or do a hard connection. Let pin 9 unconnected or connected to ground set it to Dot, connecting pin 9 to V+ set it to Bar. See the datasheet: www.ti.com/lit/ds/symlink/lm3914.pdf Hope it helps :)

[@soumyapalkundu7387]

ok thanks.

[@grejanjegrejanje0767]

What is the difference in components 12/24 Volt?

[@NienteNessuno]

R.I.P. soldering iron tip ☹️😂

[@m.jakirhossain5991]

Can you make 12.1 volt is low and 12.9 volt is full indication that means I need per led off or on for 0.1 volt up or down

[@JREMC2]

I would have subscribe to your post, but since the diagram is not available, SORRY!

[@kingoff_defeat]

Your tools like pro 😁

[@easytechzones]

Thanks

[@marwy4621]

Can i ask you? could i use only simple diodes? that means: 2x red 3x yellow 4x green and one white? will it work or i will destroy components?

[@marwy4621]

Thanks.
