Very nice experiment! I've been wondering about which boards might be most suitable for 18650 power, and this certainly answers that question. The information you provided regarding sleep mode is also very useful -- I wasn't aware that was available. So thanks very much and I'll look for the follow up video you mentioned to see whether you were able to do even better.
i dont understand your voice(fully) but this video is the most usefull video i have ever seen. can you speak more understandable ? (english is not my first language)

Its like testing car Fuel consumption without going anywhere.
Fuel consumption in idle, yes. But it's part of the puzzle, actually the part that I'm looking for: I can calculate how much everything else is using myself.
Not really for the Mega and Uno, but it does make a significant difference for the smaller Arduinos, like the Pro Micro, Nano and Pro Mini. I've recently done a video on this as well - ruclips.net/video/A3shZgR5Y68/видео.html
Where can I find those battery holders with the built in chargers? Those would be really useful. No need to remove the battery from the project to charge them.
@@MichaelKlements Ok, good to know. I bought some similar from Amazon. In addition to the charger, they also have a pair of step down regulators, one for 5v and one for 3v3. www.amazon.com/gp/product/B088BWXPB3/
Battery Time is calculated with the Formula T = (Battery Voltage x Battery Ah) / (MCU Voltage x MCU Current) which will give you the result in Hours. Hours /24 Hours give you the Battery Days without defficiency...
it's amusing that people in comments sections tend to pick on "fake battery" instead of appreciation that someone actually measured power consumption in mathematicaly proper way xD Thank you Michael, this video was really educational!
Haha, if there is one thing I've learned about RUclips its that people will always find something to complain about. At least we all learn from it and can make improvements for the next one.
Hey man can you please help me , My arduino turn on by battery but it does not run the code ?? It's like there is no code inside it But if i connect to laptop it works . Any solution for this ?
The battery is likely not able to supply enough current (or possibly incorrect voltage) to run the Arduino. The power LED might come on but the controller behaves strangely if it doesn't get enough power.
It depends a lot on the type of sensor and how you’re using it. Sensors like thermistors and LDRs use very little power where GPS and GSM modules typically use significantly more than the Arduino would. There are also ways to reduce the power consumption by sensors by only turning them on when they need to be used or using a “sleep” mode.
@@MichaelKlements brother.. i am making a project using arduino uno, touch module ttp223, reset switch, 1 digt lcd 7 segments. Can you tell me what will be the best battery source for it. I bought a single 9v battery for it.
anyone help me please. its for my school project. i made a mood lamp and when i connect to the battery(9v), the board only turns on for about 10 seconds and then it will turn off for about 3 sec and turns on again, and the cycle continues. please if anyone knows how to solve this please help me....
Some cheap 9V batteries are really poorly made and can’t handle the current drawn by an Arduino, especially if you’ve got a motor or servo attached. So the voltage drops and the Arduino cuts out and restarts.
I’ve had mine running for the last 175 days continually without a problem. It’s been on and running combined for over 250 days easy. I’m using the arduino uno genuine board.
The write-up linked in the video description gives you more information on this. They're in series for the 5V tests and then just a single cell for the 3.3V tests.
I'm wondering how this compares to, say, using an uno to program the atmega and then operating it as a standalone microprocessor. How much energy cost is in having the rest of the arduino board around going unused?
Well it depends on what you’re trying to do with it. Arduino boards in general are prototyping boards, so they’ve got a lot of components on them to make them as usable as possible but being power efficient isn’t really a consideration.
remove +5V LED indicators as well as RX/TX uno board is not low power board/components. You can also try running all processors on 1MHz not 16Mhz and see difference :)
I did a follow up on this video where I tried a couple of different things to make a Pro Mini more efficient. I got it down to using a couple of microamps, so the Arduino would outlast the natural discharge rate of the battery.
That's quite an open ended question. 9V batteries vary significantly in capacity and so do servos. It'll also depend on how often you're moving the servo.
I bought these same batteries. Once fully discharged, I charged and found them to be only 1800mAh. I learned the hard way, if you want quality batteries try Panasonic or Samsung instead. You get what you pay for. No such thing as a 4200mAh or 9800mAh 18650 on the market only cheap China knockoffs.
WOW! your batteries break the limits of physics AND chemistry just to be 4200mAH. !this video isnt very scientific, your method stands to be improved in many ways.
@@nbcq302 actually i'll partially agree with OP. Altough cells used in this video are definetely shitty and surely doesn't have 4.2Ah capacity, author's method of measurment is correct. If you really had 4200 mAh 3.6v cell, calculations would be close enough. However if you have something more realistic like Samsung's INR18650-23 with 2.3Ah capacity, just include this in your calculations :)
Do you know that for any given battery chemistry there is a measure known as power density. I don't have the number handy, but I do know a legitimate 18650 LiIon with protection weighs 45gm and has at most 2,600mAh. In order for those batteries to have 4200 they will have to weigh at least 73gm. I guarantee you they are fake. I apologize if later in the video you disclose these facts, but I have only watched the first few minutes. Very unhelpful video. Also, research what happens when using a VOM to measure sub 1A currents. Hint: it messes up your readings and not in a good way.
Nice test to see the bare power consumptions of the controllers. This test does not account for the fact that there is a voltage where the arduino stops working reliable working under a certain voltage. Especially in the case where the 3.7 volt is directly attached to the arduino. Also you did not include a battery protection to prevent deep discharging. When connecting the arduino to the batteryterminals, there is nothing stopping from going under the presumed safe 3.5 volts. The 4200 mAh rating is chemically not feasible, the max capacities with current li-ion technology, you could probably get 3500 mAh.
As you've said, this test was more about testing the current draw from each Arduino setup than it was about correctly designing/sizing a battery setup to power them. All your points are valid when designing a battery powered project.
@@carlerikkopseng7172 its an easy one to prove. The highest capacity li ion18650 battery available is by Samsung, LG and panasonic is 3500 mah. These three companies are very reputable in this field. Even then, these 3500 mah are very expensive. I doubt a random chinese company would be able to achieve higher capacity than these
First the capacity of the battery, that rating is fraud. So not a fair test. 1000ma true capacity battery will run a nano 24 hours. 8 hours a day, so 3 days.
Very valuable data collected and shared. Thanks.
True

Thanks John!
Awesome video. Exactly what I was looking for!
I think that as a fairer test you should have used the same two batteries in parallel for the 3.3V versions.
The voltage would have been the same; you would just double the total capacity. Instead of 4 months of life, you'd have 8 months.

Very informational! Thank you for sharing this experiment with us :)
Does this change substantially by desoldering the on chip LED's?

Its giving a nice idea. It would have been great .. if you would have connected few component like LCD and few relays
Excellent video, (are we there yet? 🤣🤣)
The Raspberry Pi Pico can run on 3.7v with a display attached. It's pointless to boost it up unless you need 5.1v somewhere badly.
Where can I find those battery holders with the built in chargers? Those would be really useful. No need to remove the battery from the project to charge them.

These one's also look really useful. Having the on-board power switch is neat.
@@MichaelKlements That's what I thought as well. They will be here in a few days so we shall see how well they work.
Be careful, not all of these devices are capable of proper UPS function.
is there a way to power down more than 8S ?

Are the batteries you're using protected or unprotected? They seem to be mounted on a module. Does this module protect against over discharge?
They're unprotected and the module that the battery is on is only a charger.
So finaly i found it
Good Info.

can a arduino uno board run for 30 days continuously? if i can supply power continuously

Hi sir, i want to ask, why my arduino blinking like on off, on off when i measure with my multimeter. I use 9v bat for powering arduino.
What are you measuring and how are you measuring it? This is a very open ended question.
@@MichaelKlements Sorry its my foult, luckly my multimeter doesnt broke😅. Nice video. Thanks for sharing👍
How long would a Nano last if I used it 1 minute a day?
One minute a day is less than 0.1% utilization, so it won't be much different to the test results. Probably around 20 days on a 3000mAh battery.

can I put 4 18650 lithium-ion battery for Arduino board to power a collision avoidance car
3 would probably be fine, bu t you should be able to use 4 as well.
