A nice thing with the LM3914 is that in the LED display as a "bar" mode (like he has done here), you can simply connect a transistor, mosfet, etc. to an appropriate LED cathode and if needed add a relay, and you can use the circuit to disconnect the battery under test once it has reached a "charged to" voltage and/or "discharged to" a voltage level(s) of your choice. You can also to a fair degree choose the resolution of your measurements by simply changing resistor values and using a front-end voltage divider if needed. So there's some pretty good and EASY flexibility with the LM3914 which goes beyond just visually monitoring the battery voltage with pretty lights.

thank you for showing the schematic!!! thumbs up and subed! mike

Good video, I just wish my soldering would magically clean up themselves between takes :)

I must put the map to a project so that I can get nerves and share. Explanation without a map is not good. You are one of the key source men.

I always enjoy these videos, I wish my knowledge of ICs was as good.

Very nice

I want this circuit from 48 volt baatery.please advice.

Kya hum isse tractor ki battery pe apply kar sakte hai...kyuki usme 12 v aur amp jyada hote hai...to kya amp ki wajah se ye circuit damage ho sakti hai...ya isko kitne amp tak de sakte hai...

Hi, thank you for the circuit. I made one. Same with same value components. Problem is, during bar mode, first red LED is on and keeps still during voltage change. I am not sure it stays on during bar mode. At graph mode first 5 LED is OK slowly lighting till 11, 25V but afterwards 0.5V change makes all rest of the LED light up. By mistake I cut 4, 7K resistor out of the circuit and it start working correct smooth way between 10-13, 6V after calibrating with POT... any idea what is going on and what that 4.7K stands for.

This is an undercomplex solution. The voltage depends also on age, temperature and current. You only measure the open circuit voltage which works for some special cases. Look for more sophisticated chips which implement per example EKF or other algorithms. Of course, they are more expensive.

Sir, can i use this circuit as battery level indicator for 48v battery
If not means, make a circuit of battery level indicator for variable battery voltage levels

[iamquanhik]

How to adjust the resistor to measure voltage in the range of 1V from 12V to 13V? Thanks you so much!

[LEOBER]

Me gustó este circuito, es muy útil, lo voy a construir

[bonnylusty]

Pls can it also work for 20v or 24v the way u've shown it? Or you'll still add some componect more.

[tetcpayalchougule]

Can I simulate this same project on any online simulator (if yes then please tell me 🙏)

[vaiter]

Ух! Спасибо брат. То что я искал. Спасибо!

[powerROBY]

can this be done with lm3900n and adjustable up to 17 volts with 5 leds?

[zlandiaz]

Una pregunta. Hay que regular lo cada vez que se cambie el voltaje de la batería????

[alexpanzer]

How can i reverse the LED lighting from right to left? I want to use it for a fuel tank level indicator but the resistance of the float it has reverse connection (when the float is on the top of the fuel tank it shows that is empty) and i can't change it (is in the fuel tank of my car).

[Juniorfinger]

Wow creatif be smart... apakah ini bisa menjadi tanda tanda full batre? Witout resistor ?

[deltax]

Question: It is possible to make it work with 12 blue leds?
