How to use 18650 Battery Shields (USB charger, Arduino, ESP32, ESP8266)
HTML-код
- Опубликовано: 17 авг 2024
- I purchased 3 different sizes (1 Cell, 2 Cell, 4 Cell ) of the 18650 Battery Shields and in this video I'm going to review them, connect them up and show you how they work.
These modules are hardy for your electronics projects to connect to Arduino, ESP32, ESP8266 and all they 3v and 5v accessories. or simply just use as a USB charger for your iPhone, Samsung, Android or what ever device you have that charges from a USB cable.

Thanks man, couldn’t figure out how to turn the thing off but this vid helped me
Is it possible to use this module to supply a raspberry Pi while chraging the battery cells at the same time?
I bought the 4 cell one. I found that to power it down you must push 2 times the button and to power It up 3 times. Also, the sliding switch seems to do nothing....I charged (under a looooong time) , 8 cells (I use 2 cells in parallell , so I put 4x2..yes: I am an evil one!) Worked fine!
The switch only works for the USB power. The 3.3 and 5V are always on, except if using the push button as you noted.
Very informative. I'm planning to use this baby into my project but not sure how it works but your video helped me to decide. Thanks a lot!
Thanks for doing this video, its good quality and you hit all the important points.
Hey, thanks for sharing this. My shield is quite similar to yours but includes a small switch (hold/normal) that keeps the shield on without a minimal load (hold) and in normal mode, it turns off if there is no minimal current. I was wondering if there's a way to monitor the power level of the battery so I can read it in my project. Is it possible to solder a 3V output and ground with a voltage divider? Any suggestions/ref? Thank you in advance!
Is it bad if I use the button top batteries with them? They’re hard to squeeze in but they turn on. One issue is that the little micro chip on the other side gets super hot. Is that related to the button top? Or something else?
thanks very much for filming & uploading this video matey - cheers :¬)
Very helpful! 1 question pls, can the module charge and discharge at the same time? I want to drive an Arduino from a small solar panel, with the battery providing power overnight. Thanks, Steve
can the batteries be charging with a solar panel and at the same time be powering a cell phone?
One question, can i charge the batteries while i'm using it to supply a esp32 ?
did you find out? I have the same doubt
@@Emi-fg7fn Do you know the answer?
Any news?
Hi i just got this recently, sorry for the extremely late interject.
The answer is Yes and No:
You can use while charging, but the moment you unplug the charging cable, it shuts off long enough to cut power to everything before turning back on. This does not behave like a UPS.
Very informative video friend, mind if I ask something regarding these battery boards? If I wanted to connect these to a solar panel to charge, where can I connect the solar cells to charge the lithium batteries? The soldering tab does not seem like the solution, do I connect those to positive and negative terminal on the bottom panel? Thank you for the very informative video, bless you and have a good day friend.
Yeah, I was wondering the same. Not sure can we connect the wires from the solar panel to the micro USB port which is used for charging. Also I'd like to know if we can draw current from the shield and charge it at the same time (which is needed for off grid weather station).
Question can it charge and be discharging at they same time ?
btw when we turn off the charger nodule will turn off fpr a sec how to overcome this problem??
One would think that with all the features of over charge, under charge, it would be cheap and easy to reject if the polarity is put in incorrectly
Is it useful for mobile charging or it will be harmful for mobile charging ?
Is this okay to use as a power source of a nice nano keyboard and be able to use to charge a phone at the same time?
No. This would cause the charger to never reach the cutoff voltage, overheat the battery, and may catch on fire or explode. Either charge it, or power a load, but never both at the same time.
Does it have discharge protection? That is, will it shut down once the battery gets down to 3.1V for example.
Are you able to have say solar panel plug into the input to charge the batteries and then have the USB type A output to a Arduino and run off that?
what if I dont want to charge the batteries.. and instead just use it as a power source ?
Thanks very useful information, great video 👍
At what values of the incoming current 200-300mA, the module will continue to function?
Is the usb port always on untill the batteries are dead? Even with low current draw?
can this charge and discharge at the same time?
Is there any pin to read battery charge status? Or any spi or i2c port to read battery voltage and current?
Do the battery level LED's turn off on yours? On mine they just stay on and waste power.
they stay on until you turn the unit off check out 7:20
So wasting power indeed. Better to remove the leds for a remote project. Thanks
I purchased the dual shield DIyMore (2 of them). of course if I try to use it as a UPS it won't work since it charges very low a .5amps. So just to charge the 18650 without anything connected to it (not being a UPS or drawing a current) it actually slowly depletes the batteries. I can see the red LED lights get less and less over hours. I'm assuming these are both bad boards? Anyone else have the same issues? Also the green LED never comes on since it always depletes the cell power. HELP! Bought from Amazon. Guess I should return them.
Here is why the green light (or blue) never comes on ...
It is never recommended to charge an 18650 lipo at the same time as using it to power something else. It is not a two-way street. Pick one or the other. If you have a load on with the charger on, the charger will never reach the cutoff voltage, which then overheats the battery and may cause it to explode. Just saying. :)
Thanks !
What is the function of on-off switch in this charging module?
I am asking myself the same question. It seems to do nothing. Alas, the last firmware version of the 4 cell board powers down with 2 push button touches and powers on with 3 touches. It makes sense : if We accidentally push once the button, something happens....pushing It accidentally twice is something highly unusual.
As I mentioned before,, the switch is to shut off power to the load while charging.
Here's why...

Hi, can i use it while charging?
I wouldn't personally recommend charging and playing at the same time,
Thank You For the explication
You are welcome!
Amazing
Thankyou
anyone found lifepo4 version ?
You should get a tripod
PLEASE get a tripod....
