Project Description:
********************
In today’s episode, you will learn how to make 3.7V Lipo and Lithium Ion Battery Monitoring System using Nodemcu ESP8266 WiFi Module, TP4056 1S battery charger, SSD1306 Oled display Module, and the New Blynk V2.0.
You need to be very careful while working on battery powered projects as you are not supposed to Overcharge and Over-discharge your Lipo or Lithium Ion battery. Overcharging can make your battery explode and it has practically happened to me. Being an engineer, when I knew all about it, I still made the most stupid decision by purchasing this battery charger. You can clearly see there is no protection circuit. The Lipo Battery overcharged and caught fire. Thank God I was at home so I quickly put out the fire. So, just don’t purchase a cheap battery charger; buy the one that has a charge protection circuit. Like this Imax charger; I have been using it for months and until now its working just fine.
Anyway, just like Overcharging, the battery over-discharging is also not a good thing because if you continuously over-discharge or completely drain your battery it will tremendously reduce the battery life span. Just take a look at this Lipo battery, I used it to fly my racing drone. It looks like a new battery as I have been charging it using my Imax charger, but its dead now because of over-discharging as I was pushing it to its maximum limits. There wasn’t any voltage monitoring system so I had no idea when to stop flying the drone.

#3.7vLipoBatteryMonitoring #batteryvoltagemonitoring #TP4056
I'm constructing a series of RPI Pico "computers" for myself for now and it's getting interesting. I'm on a clock quest at the moment, so I can log voltages, temperatures or GPS speed or whatever. I make a lot of adapters and circuit modules to get things going. Videos like this are very helpful.
You are great 👍
Very useful channel and clear explanation
Thanks a lot
Good subject matter but the background music is unnecessary and distracting making it very hard to hear your voice.
@@TimRickey you are right, now I don't add music.
Great as always 👍👍👍
If I wanted to use ESP32, what would the equation be like?
Make a vedio about battery charger and load sharing , please ☺
Awesome video!
Have you ever faced with the need of updating the firmware after hardware has been already shipped? Would be very interesting to watch some video how to update firmware remotely.
thanks to Arduino. Designing is so easy
Ya it's so easy. Now I will also start designing products so you gonna see a lot of new things
You know semiconductor physics?
why is the battery percentage going forth and back ? help me please..
Very cool video. Btw, I have exactely the same charger/balancer. However... mine is fake, cheap contraband and very unreliable. So sad 😞
Mine is working awesome.
@@ElectroniClinic Nice to hear !
Is it possible to make 36v litium batery management sistem like your project in this video:?
Ya you can. Watch my video on ebike battery system.
Sir can I use 3.7V battery directly with nodemcuesp8266?
Yes
@@ElectroniClinic without any voltage regulator?
Ya, you don't need a regulator.
Nice video. But dont like the bg music.
Thanks a really interesting project. Could this project be upscaled to monitor a 13 volt lead acid battery.?
I have already done this. Check playlist.
Yes I did see this thanks and built the project exactly as you said but it would never work. I'm trying to monitor solar panels in a remote building. Thanks again for you interesting posts.
@@g7mks383 not this project, this one is for 3.7v. I am talking about my projects on Lead acid battery voltage monitoring.
Sir,
After verify the code, there is an error: extended character - is not valid in an identifier.
Battery_Monitoring:58:11: error: extended character - is not valid in an identifier
58 | return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
| ^
Battery_Monitoring:58:34: error: extended character - is not valid in an identifier
58 | return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
| ^
Battery_Monitoring:58:57: error: extended character - is not valid in an identifier
58 | return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
| ^
exit status 1
extended character - is not valid in an identifier
The code as below:
mapfloat(float x, float in_min, float in_max, float out_min, float out_max)
{
return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
}
I have try to modify the code but it is still happen an error.
Do you have any idea?
thank a lot
bhai same problem
Hi 🙋♂️
How can I check the battery status of a 12v Lipo battery using a microcontroller when the battery is underloaded? I want to know when my battery will run out
Thank you 🙏🏽
I have videos on 12v batteries. Kindly check playlist
@@ElectroniClinic name of the video or link 🔗
Can you help to get battery voltage of my off grid system.
Need to on off the relay by blynk through on off switch and get the battery voltage by gadge with supporting esp32 board
I already have a video on this. Check playlist.
@ElectroniClinic yes but the relay
Control and voltage calculation both code I'm facing issue can you help me to creat the code I need only battery voltage calculation and one relay control by blynk
@@mohamedmalkhaan4111 ya I have explained how to monitor the battery voltage. Check playlist.
Hi dear I have checked the playlist but couldn't found can you help me need to control 1 relay and get battery voltage
please write a code for solar controler 48 volt batter monitring and also monitor charging current 50 amp max
