- I show how to very easily charge, and then use 3.7 rechargeable lithium ion batteries in small simple electronics projects such as Arduino based projects or small motors. Two of the modules covered are the TP4056 and a 03962A which is also based upon the TP4056 but additionally has battery protection.
I also show how to get 5 volts out of a 3.7 volt battery.
This video mainly covers the 18650 but demonstrates how to use it for other lithium 3.7v batteries. - วิทยาศาสตร์และเทคโนโลยี
!!A Warning for anyone using either of the TP4056 charging chips in the video!! They cannot be directly attached to a load when charging, because the detection circuit never detects when it has gone past the +/- 10% of 4.20 volts. This is true even if the load is just a couple Milli Amps... At best will damage your li-ion batteries, at worst can start a FIRE! Tinkerers BEWARE!
Thank you very much for this advice!

This guy has a pretty convincing argument dissmissing your claims at around 5:30
I feel grateful this reconditioning program th-cam.com/users/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 was started. I had Three dead batteries scheduled for disposing of. Having said that, I tried out reconditioning them and it took me only an hour to do it! It doesn`t matter what type of battery you want, the process works.
I know this video is old, but very valuable. You should change the title to "Lithium 3.7v batteries basics for projects", as you are not focusing in arduino, but you are giving a lot of very important information about the batteries, and in a very fast way. Enjoyed a lot, cheers.
clear, concise and informative, it's all you need really, thanks for the upload!
Is it ok to wire the TP4056 output directly into the 5V on the Arduino Nano? I've been doing that to run a small OLED display and some tiny sensors, and it seems to be working fine, but I don't know if I'm messing something up by doing so.
Here's a dumb question: I can charge and drain the batteries at the same time?
I want to make a GPS Tracker that charges only when the motorcycle is on, and i'll not have access to the battery.
Hi, I got some 18650 batteries here, are those good to be used with arduino nano, clock module and pir motion sensor and led matrix? I'd like the clock to last long time. for now I'm using a power bank 10000 mAh (?) but that only last a short week
I am starting my first project with an arduino and I need to control 4 3.7v motors for a drone. I thought the 3.7v lipo is fine but on the arduino page it says between 6-12v to power up the board. Can you help me choose the battery for the 3.7 motors if I am using an arduino to control them?
I wonder if I heard you right. You pointed out the TP4056 didnt offer any low voltage protect. The specs i read on the module says it does offer it at 2.5 volts. Which is correct. I do need the low voltage protect Thanks
I'm doing a school project with the arduino uno..our task is to create a autonomous vehicle that can navigate a course and locate a marker..I was thinking of using 18650 batteries...but not sure how to power the motors...2 batteries make 8.4-7 volts..the motors are 6v..any ideas on how to wire that up?.and what pieces or boards I'll need...I'm new to this..and want to get good run time..all while keeping the vehicle under a 6x6x4(inch) foot print. Thanks in advance
Wanted to use some li batteries to run a 6 volt timer
Can you give some insight on that type of project

Nice video, thanks for sharing it :)
Nice. I have similar question like Loïc Rosset here it is:
can you use the charge module to recharge a battery, i mean to hooked it to a load and use the energy from the battery. But to do it with the same terminals for charging. The reason that i ask is that i want to use this device as a battery bank and to be able to charge it and discharge it from the same terminals
Quick question: If using the module that regulates charge as well as discharge, If I connect it to my arduino board and then plug the usb into the arduino to upload a program, will the battery be protected? I understand that if you plug the usb into the arduino it will attempt to charge the battery.
will one of these charge boards charge 2 of the 18650 batteries ie. a double holder and a 03962A Board?
I want to run a self contained weather station using an Arduino Due.
What's the module for the series charger for the batteries? And what's the module for the usb 5 volts?
Great video.
If I want to use one of these for an esp-01, that require 3.3v, what can I do?
can i charge my drone lipo battery 3.7v. 650mah with tp4056 and do i need u change the resistor
arallel Connection
If higher currents are needed and larger cells are not available or do
not fit the design constraint, one or more cells can be connected in
parallel. Most battery chemistries allow parallel configurations with
little side effect. Figure 4 illustrates four cells connected in
parallel in a P4 arrangement. The nominal voltage of the illustrated
pack remains at 3.60V, but the capacity (Ah) and runtime are increased
fourfold.

Hello, are you sure about the recommendation of using the 03962A over the TP4056? the TP4056 specs says it is the one with over and under voltage protection.
Great video,thanks keep it up.
Do you have any more information on this? I'm interested in buying an over and under voltage protector as well and am not sure which one will have what I want
@@ColeLashley Hello, it looks like the tp4056 has a newer version which has a couple of more ic chips and that one is the same as the 03962a. Searching on Amazon for tp4056 looking closely at it some have 03962a printed on the board. Hope that helps.
@@steve8939123 Thanks that helps, I was able to find one that suited my needs
@@ColeLashley you're welcome
Any links to buy the 0396a?
Is it alright if I use two 14500 li-ion cells in parallel, with a 03962A module?
I just made a small portable speaker using those and PAM8403 audio amp, and so far they work great.
You could, but you would need to take them out to charge or figure out how to balance charge the cells individually.
@@billybbob18 hey, thanks for the reply. It was long ago, and it worked perfectly for almost two years 😄
Does this module have an output for microcontrollers like Arduino? If yes how many v as Output?
Thanks
Can we wire 18650 battery to an arduino pro mini 3.3v directly? Or shoul I use step up converter circuit like you shown, before the arduino pro mini 3.3? is it necessary for this situation
Arduino Pro Mini has RAW power input with voltage regulator which can handle from 3.4V to 12V, so as long as you supply the power through RAW instead of unregulated VCC it should work fine
You say that could only charge one 3.7v battery at a time with a 03962A . What would happen if you try and charge three 3.7v batteries in parallel? Asking for a friend!
Can the battery be charged at the same time the circuit is powered when using one of those usb boards?
it can, but the load needs to be tiny. if the load =< 5Ma yes. other than that, NO they cannot. It will wind up destroying your lithium ion batteries
Can we use one tp40 to charge more than one cell
I was originally going to ask you what the other two boards were that you showed in your video but didn't give the name for. Then I would study up on them myself, since you said you were happy to answer the questions left here. Nevertheless, I see that you are generally not answering questions left for you. I'm sure this is falling on deaf ears. This could have been a really nice channel. Oh well.
I'd like to know where you're getting those 03962A boards for "fifty cents a pop". Best I've been able to do so far is about $1.50/ea.
How do you use these to power 6v servos? One isn't enough two is to much.
Title is about using 3.7v Batteries on an Arduino but then you don't mention the Arduino or how to use a 3.7v battery on one at all? Would you connect this to the 3.3v input or to the RAW input? I ask as I have tried using Nicad packs of 4 to power on the RAW and when the power falls below 4v the Arduino starts to play up?
Andrew Brierley did we watch a different video? He mentioned using a small DC-DC step-up converter to boost the voltage to 5V for your Arduino project.
what is the part number of the usb converter you had at 5:40.
found it on ebay DC-DC Converter Step Up Boost Module Power Supply USB Charger 5V for Phone MP3/4, the type 0.9-5v to 5v 600mA W/USB. www.ebay.ca/itm/DC-DC-Converter-Step-Up-Boost-Module-Power-Supply-USB-Charger-5V-for-Phone-MP3-4-/400767258219.made by Shenzhen LC Technology Co., Ltd. www.chinalctech.com/index.php?_m=mod_product&_a=view&p_id=877
What was the board at 07:53?
great!
Can the device work while charging?
I dont get it if arduino is drawing 5v how can I use 3.7 batteries in my arduino project, can those '03962a's convert 3.7v battery input to 5v output ?
Did you miss the part at 5:30?
@@ColinRichardson No, but he said arduinos are happy with as low as 1.8V so I wonder which input you can use.
Thank. You.
Thank you.
Is it possible to charge and discharge simultaneously with this module ? With a parallel wiring ? How ????!! :)
Thanks
I think as seen at 2:46 you connect battery +/- to opposite side of usb port and connect arduino +/- to the ones on the same side with usb port as explained in 2:07 and afterwards, so it enables arduino to draw power from batteries, as well as usb input to charge batteries
@@berkcan3475 I've soldered my bat pins, and charged and discharged the battery with the same Bat pins, this worked pretty well :)
Apparently it cannot because if you put a load >5mA then the charging module cannot detect the correct voltage of your battery and you could destroy it or worse. cf. Lindsay Cox comment.
Great video! Is it possible to charge the batteries and use them at the same time? Or the current used will "fool" the charger believing the batteries are never fully charged?
+Loïc Rosset So far the only material that I have read says to disconnect the load while charging. That said, I have left this connected to loads while charging but those loads were very very small. They weren't something like a motor, or even a powerful transmitter. My load was in the 30 ma range.
LessonStudio when I have used the newer ones, I've left the load connected. Once the circuit detects that the voltage has dropped below a certain level, it disconnects the load, then reconnects again when another higher threshold is reached. Over time of course unless the batteries are allowed to fully charge now and then, it will lessen their capacity and shorten their lives.
Looking at my uncle's Tesla
Tesla: *oh no fkin way*
Is there anyway to wire six of these 3.7 volt batteries get 11.1 volts?
Two pairs of 3 in series instead of parallel will give you ~11v. You can do this directly or there are fun little boards that will make this possible. There are two challenges if you do this "naked": Getting them not to over-discharge as that will destroy the batteries, and then charging them back up in-situ.
where you getting this stuff for like 20 cents at?
Thank you very much for this video
Can solar cells be used for charging?
why not? :)
Say you had a 2000 mah battery and a 500 mah battery that are both 3.7 volts. If you had one of these modules, charging the 500 mah battery would not damage the battery correct.
+Jacob GoProVideos Correct. As long as you are charging them separately all should be fine. These modules work on the voltages being pushed back by the battery. Thus the smaller capacity battery will simply push back higher voltages after less current has been pushed in.
+LessonStudio thanks I appreciate it
0:52 Pretty sure that for comparison, that was a AA battery...
What is the power rating of one of the batteries?
Ultimatefire54 how long is a piece of string? 18650 lithium batteries come in varying capacities.
so, OUT+ and OUT- is 5V? I didn't see the demo. It's a little confusing
same here
Where are you finding those for under a dollar?
China
what was that USB thing called?
0.9 to 5VDC USB Booster Module
do they even make 4v double a batteries or even 5v ??????????????
mangreat71 AA batteries are the same size as 14550 lithium batteries. 18650 batteries are like giant AA batteries. 14550 (14mm x 55mm) lithiums will fit in AA battery holders but of course their nominal voltage is 3.7v instead of 1.5v. 14550 sized batteries may also be Ni-Cd or Ni-mh but again not 1.5v.
Use a better quality USB cable, I don’t think your led was too bright.
Compare that to a "B" battery.
Good content, thanks for that.
However, constant movement of out of focus items is not good. Perhaps point to the items rather than all the waving about.
Sorry to sound negative, I otherwise liked it.
*interesting points ,if anyone else trying to find out how to recondition used car batteries try Panlarko Recondition Planner ( **lovy.biz/zrsy** ) ? Ive heard some super things about it and my m8 got great results with it.*
To recovery dead battery,Thumbs up from me
Thanks for participation in the discussion with valuable suggestions.
thanks for your opinion. Right this guide work to battery recondition
can you please send me the board please thanks buddy
just parallel all the battery together than charge with one of them
dont do that unless they are all of same specs lol
change your name...
@@goku445 no u
@@user-jp1yd2ut9r you're fucking the layout. What are you 12?
So, how would we charge say 4 at a time ? with 4 tp4056 ? how to wire it up ?
Could you charge 18650 using the TP4056 via solar panel (12v to 14v DC output) without a solar panel controller?
