- TP4056 LiPo Charging and protection board
In this video we look at the TP4056 LiPo charging and protection board. It is a 1 cell (3.7V) charger with over current protection, undercurrent protection, overcharge protection, damaged battery detection and thermal protection.

was the clock still running when you are charging the battery? or did you remove the output wires out then charge the battery
The clock was plugged in. The 4056 will allow you to charge and discharge at the same time.⌚
ok, i am making a 3.7 volt and 5200 mAh battery is it possible if i wire a 5volt boost converter to the charge output( out + and out -) and still get to use the battery power?
Francisco Sanchez yes indeed, in fact, Adafruit sells one called the "Minty-boost" for just this purpose
the out + and out - is for using the battery power? and the B + and B - is to charge the battery power?
Francisco Sanchez correct out is load, B is battery
I like this, for powering small projects.
brilliant and simple video mate. much appreciated.
Nice little video, quick and to the point and informative. However, the only thing to note is the cutoff during depletion. Yes, it will cutoff when the voltage drops below the bottom voltage, except that, when the 18650 recovers back to safe voltage, the unit will turn back on; and this will keep happening for awhile. It is possible to super drain the cell; just not 0-voltage the cell like that would happen w/o the protection IC in place. Julian Illett demonstrated this one of his videos.
Great job, tho, on the explanation and great video quality! :)
While I have not searched extensively this is the first time I have seen anyone comment on the fact that this is only a charge protection board and does nothing for discharge protection. I volunteer at a makerspace as a consultant kind of person "generic dork" and these modules I hate soooo much lately more than anything. Alot of people are wanting to do R-pi zero and pico and esp32 projects that are battery powered and turn to this board and soooo many would have been better off using just AA batteries or even coin cell batteries with the sheer number of batteries wrecked by this module.
I would be interested to know if you know a board that also has discharge protection as my searches have been fruitless.
@@Segphalt Are you certain that you are talking about the same board functionality,AND that the users are wiring it correctly to take output to the load through the board and not direct wired to the battery?
While a more simple 4056 board only had the charging, these have discharge protection. While it is true that they might shut off a load at 2.4V, then the cell recovers voltage and it switches back on, this is a bit of trivia rather than a concern as it still switches off again, and again, and won't come back on once the at rest (0 current) state of the cell is below ~ 2.4V.
@@stinkycheese804 This is the behavior we have observed but it will happily oscillate forever all the way down to 2v for projects with significant load. The board works fine and stops this behavior for less than 100ma draw projects. For bigger power draw projects it is just a battery murderer.
The 8205A is just the mosfet for the DW01 (and not a protection chip in its own right) which will allow discharging all the way down to 2.4v which is a bit further than I would call safe. The overtemperature feature of the TP4056 is also disabled on this module so it might not be as safe as you're lead to believe.
Great! I'm planning to buy wireless numpad and the battery is very small so I will buy great battery and this chip and make it work so it last a long time on 1 charge. THANK YOU, you explained everything!
What circuit do you suggest after the tp4056 for a project with a solar panel powered system to keep that thing running for ever? is it possible to connect it straight on the tp4056? does it not drain the battery if you charge and use it at the same time? The Power IN does not go direct to the Power Out, it goes only over the Battery. i think thats a problem.
Thanks for sharing this video!
I too did mount this module with hotglue and over time it has failed due too the heat transferring... I found that covering the entire backside to work best or epoxy it and call lit the day
I was about to mention this! The board does get pretty warm under significant load, so the low melting point of hot glue can be a problem.
It is a bit unfortunate (almost to the point of being insane?) that there aren't more Chinese manufacturers that include mounting holes on their PCBs, then if they really must, they could laser cut perforations so those who don't want the slight added dimensions of the PCB to include those mounting holes, can just snap them off the PCB. Hot glue is a poor solution and epoxy quite permanent (unserviceable), particularly for a board that has to endure the repeated plug cycling of inserting and removing a USB plug to charge the battery.
Thank you this is exactly what I needed to know!
Question - i bought 10 of these boards, and made me a battery bank charger for up to 10 cells. it wasn't acting right at 1st, but then i realized that i had to add in some filter caps on the power input
side of the boards. i got it all up and running fine, every battery showed as charging, some took longer. i kept checking on them, and a few stared to get hot. i terminated charging on them cells.
i noticed that the chip is capable to use a thermister. but on all of these boards that are available, the thermister is not used. but the schematic shows that one can be used,
but it shows no value to use. i looked a the data sheet, but it gives no insight on what sort to use... do you have any advice ? i wonder if the ones that are on the laptop battery packs or tool packs would work or not, i think if i have this i can have more safety on my cells when charging.
comments please...
any recommendations on PCB that has max charge 4.1V and 3V discharge?
Do know if something that same but have trigger on/off for the output
I think you can trick the overdischarge protection using a low current drain device like a led. LED Uf=3V Maximum cell voltage (U) 4.2V R=60 to hand out a maximum If of 20 mA.
You are not making sense. If LED forward voltage is 3.0V (and that is abbreviated as Vf, not Uf), and cell voltage is 4.2V which is abbreviated as V, not U, then current is 20mA, there is no appropriate "If" designation involved. Now to roll all that up into a statement: If the forward voltage of the LED is 3V, then the LED should have stopped conducting significantly (far far below 20mA) by the time it hits the protection cutoff threshold of about 2.4V. Still, I would not leave the load connected indefinitely as there may still be parasitic losses. On/off switches exist for a reason. ;)
Nice Video and great information on that board. Thanks
How do you connect 2 of these modules so when you charge battery to charge it with only one cable
Can I use these output connections with simple 10 LED chaser circuit using CD4017 and 555 timer IC.....?
If it is then for what time it will work after charging a battery full?
Can I use old mobile battery for it (Lithium ion)???
Pls reply
so what if youre not using lipo? youre using a li-ion 18650 here... so will the li-ion still be cut off at the what i assume is the 3.5v that a lipo isnt supposed to be lower than? is it always set to be on lipo? i have plenty of 2s and 3s lipos i can take apart to use the cells but i wanted to use 18650s because i have more of those laying around.. but not if its only gonna charge everything to 4.2 and cut it off at 3.5v.. thats wasting a ton of potential energy for something that doesnt need to be cut off at 3.5v, aka, cutting your potential life to way shorter than it could be if youre not using li-po..
Can I connect an AC 6v input into the input pins (Key word is AC)? I want to power some LEDS with a 3.7v lipo battery.
ok, by any chance do you know how long battery last? i using 3.7 volt 5200mAh and converter it into 5volt 600 mA? I am make a Bluetooth headset, using 2 one watt speakers, and audio amplifier
Thank you for your good video. In reply to one of the comments you said that this board boosts to 5V but I see no inductor on the board. I think all boost circuits need an inductor. Is that true? Which IC does the step-up?
Ahmad Sajadian let me look at the spec sheets and get back to you
You are correct, there is no step-up. My mistake. Thanks.
learnelectronics
You said it doesnt boost but replied to the next comment it does. Whats the truth?
Excellent video thanks
Thanks.. I've seen these on eBay and ofcourse they come with no instruction..even the seller couldn't tell me voltage values or how charging worked..in fact the sellers didn't have clue what they are..
Hi New to electronics, just purchased one of these can you use it to say charge a larger 12v battery say out of an emergency light unit?
No, it can only single cells (or batteries comprised of parallel cells) with a full charge voltage of 4.2V. If you are new to electronics, please stick to simple projects where safety is not a concern, not emergency (anything) equipment. Thanks.
what are the + and - by the usb port used for?
Hola que tal, mi pregunta es si puedo usar este modulo para cargar una bateria de 6000 mhA, y conectar una carga en mi caso una TABLET, el modulo carga la bateria y tambien se puede usar al mismo tiempo , crees que sea posible ?
ty, this gave me the information i needed.🙂
Im trying to do the same thing, but with 3 boards and three batteries. I want to get about 9V output. But when I put the outputs from each board in series, I only get about 3.7 Volts.
can i use this board for Cell phone lipo battery i want to use 3 battery in parallel from samsung galaxy for one of my projects.
tnx for the explanation
Is hot glue the best way to mount this thing? I know alot of people do that but I am wondering if that has any effect on the board.
Surprised it does not come with mounting holes of any sort
I agree that lack of mounting holes is a legit gripe. Hot glue is a poor solution because the board can get hot in use and soften the glue. However, no the glue will not, neither hot nor cold, pose any problem for the PCB, except that if it were molten and found its way into the USB socket, it could foul the contacts or interfere with plugging the charger into it.
Quick question. I'm very new to this and I'm probably asking a really stupid question and i apologize for my lack of knowledge.
Now i know you cannot connect the output going to the battery in a series connection and expect to charge a 13s li-ion configuration with 13 of those boards without first disconnecting the series connection via some form of switch, but is it possible to connect the outputs from the battery in a 13s series connection?
I'm asking because I'm a cheap wad trying to make a ultra cheap 48 volt li-ion charger and discharger. I'm only planning on pulling 1st amp per parallel cell group so i think it can handle it but i would love your input. Otherwise I'm just going to try it and figure it out myself come hell or high water lol.
+Panic The Scholar Knight. This board is designed to charge one cell only
Does it have pass through charging?
Nice video! Question: According to the specs of this board, the battery over-discharge protection voltage is 2.5V. If I use this with a Lipo battery, isn't 2.5V to low for a battery?
You are correct. I just looked over the 18650 specs and it does say cut-off 2.75V. The TP4056 has 3 ICs in it the DW01
controls the output and according to the datasheet has a cutoff of 2.5V. All I can tell you is this board is used with 18650's all the time. My best guess is that it may shorten battery lifespan if you constantly go that low, but I doubt any damage will occur.
fs312f-g is better it has 2.9V cutoff , same pin out as dw01
You can change the charge current by changing r3. Is it possible to raise the overdischarge voltage in a similar way by changing r5/6??
hmm i got some of these and they only output after you connect the charger when you remove the charger they still work but if you remove the battery you have to reconnect to turn the output on ????? what is going on ???
Hey cool video. I have the same thing except the tp chip gets 120f hot I am charging a 3000 mah Samsung. Q thirty. It seems to work fine but I am worried that it won't last as long as it should. Is it possible I have a bad batch or is this normal?
What board should I use for lifepo4 32650, thanks!
Hej do you know where i can buy 1 of these please ? I looked on ebay and they charge 5 times more for shipping than the item is worth. Is there any item that has one of these in so i could salvage one from? I just need 1 so i can make a charging board for my lithium battery. Thanx
Thanks for the video and the explanation.
I have a question that I want to use the Tp4056 circuit for my project with the intention of plugging in a 5v charger continuously 24/24h, will it affect the life or durability of the circuit, if so, the life of the circuit will be how? so connected. How long? And is the IC's heatsink necessary?
Hope you will respond to the above information (because my English is not good, sorry)
If the charger is continuously on 24/7, what is the point of having the battery at all? If this is for emergency backup lighting I suppose I could understand. No, it is not a problem to keep it plugged in. No a heatsink is not necessary unless your discharge current is high enough to cause it to overheat, at which point it will shut down output until power cycled to reset it. You would determine this peak threshold experimentally or just opt for a board rated for a higher continuous discharge current.
If you had say two of those cells in series, would you be able to charge them both with one TP4056?
No, it senses 4.2V cutoff charge level so you can't do cells in series. If you were to instead connect cells in parallel, then they will simply charge at half the rate of one, assuming equal capacity cells.
@@stinkycheese804 That makes sense. I'm looking for a way to charge them in series since I need a voltage that is double the 3.7v.
Is it possible that a 3.7v lipo has bms built in so you wouldn’t need the protection circuitry? Or am I missing something? Thanks!
Some cells have protection built in and some do not. However, practically none that do not have a USB socket put into an end cap, have any charging circuitry so you could still use this board even if your battery has its own protection circuit.
Hey Big Clive. would this lipo/charging board combo be compatible for solar charging please? I wasn't sure how it would fair with fluctuating input voltage
It's for one cell only
@@learnelectronics thanks, so you could connect a small solar panel to this board to charge that one cell?
Hey. Question for you. Can I use one chip for 10-20 batteries wired in for bulk charging/testing? Or does it have to be 1 chip-1 battery? Thx, GearHead
It does not have to be one PCB per each battery. You can put multiple batteries in parallel (not series) and use one of these PCBs, but beyond about 3 cells in parallel it becomes impractical because the charge rate is so low, and also within the limit of the discharge current, would you really need that many cells?
So in theory yes but in practice it would be silly and not very useful to construct a circuit where only one of these handles 10-20 batteries. Besides that does no testing, just use a full featured battery charger if you need charging and testing a lot of cells.
Wow, the cable very fit on those solder point. what size of your cable in awg?
Rizaldi Ryan been a while, but 22awg I belive
Hi @learnelectronics, What happen if the battery I got has its own protection circuit. There is a issue with that?
It will be fine
so it also has protection board right? over discharge protection so i can connect non protected cells?
Yes you are correct.
Dear learnelectronics, another great video from you, thank you. Do you happen to know the name of the sound/music track used that can be heard while you are soldering at 2:17 ?
Greetings
No I don't, but I can tell you it's from the TH-cam free music library, and it's under electronica.
Thanks a lot!
Can the be used to charge three 18650 batteries wired in series? I connected the Bat leads to the input/output leads in the balance board. All is well until I plug in the micro usb. Then it fries the TP4056.
No, only one or more cells in parallel.
So what voltage is the battery unit supplying to the clock project ? I'm assuming the TP4056 is stepping up the 1860 voltage from 3.7 ish to 5 volts ? But you haven't stated the output voltage, so I'm just guessing. Cheers :)
Paul yes sir, boosts to 5V
??? it doesn't boost
Paul: most TP4056 boards use the TC4056A chip these days, they are not boost converters. For this just add a simple/cheap 'arduino boost converter 5v'. If you need an on/off slide switch, add it between TP4056 and boost converter.
What most don't know is that once you have everything wired up you should 'jumpstart' the tp4056 with charging it via usb for 1-2 seconds, so the whole thing starts
if i wanted to add a power on/off switch should i put it on output or b?
I would put it on the output of the 4056, putting an on/off on the battery side would require the switch to be closed (on) while charging which isn't ideal.
it would mean you would have to have power on (to your device) while charging.
i'd stick to output!
so you are charging a lithium ion battery with a lipo ion charging module ?
Hello, sorry for my question(and my englis xD): if i have 4 batteries and 4 unit parallel , can i charge all togheter with same mini usb charger(5V 1A) on one of these?(soldering the B-/+ in right way) !
Than, can i use the same circuit for power on a device but soldering OUT-/+ of two couple of unit in sequence and than this pair in parallel as i need an output of 7,4V and bigger "mah" as possible?
Thanks in advance
Luca
+Luca Cimmino No, I'm afraid that the TP4056 is for a single cell only. Connecting them together is dangerous.
Thanks for watching, commenting.
learnelectronics sorry but maybe i had write in a wrong way: i had seen a couple of video where they put one unit each battery, soldering all - together and all + together (those next to the mini usb port) and than from the last one -/+ to a charger! Now instead to soldering a cable from last -/+ to a charger, if i use a normal miniusb charger(like for mobile phone) connected to the last unit's miniusb port, does it works fine?
In this way the units are connected at same time(parallel)on -/+ for charging them; now if i need to use the batteries to power a device(4batteries, i need 7,4v 5200mah)and i want to use the same units for batteries' protection, can i connect 2 units' OUT+/OUT- in sequence x2 and this 2 couple's OUT+/OUT- than in parallel? Or the units works alone also for the output!??
Thanks for your help
+Luca Cimmino hooking tp4056 modules is not recommend. If afraid I can offer you any help with this.
Can you tell me the
lithium charger I could manufacture, for a battery of walkie talkie of
7.4V lithium without midpoint, there are just 2 pines for operation,
what do you think ??? And what module you could serve me
Thanks in advance for your answers
2 pins? You would have no way to balance charge them. I would be wary of recommending anything.
Its too bad the battery protection circuit doesnt cut off the 18650 li-ion battery @ 3.0v , which is more ideal IMO, even though the manufacturer states its lowest can be @ 2.5v , draining it that far down on a constant basis could actually lessen the batterys life at a quicker rate, you can still get a good 3200mah from a 3400mah battery at the higher cutoff.
replace dw01 with fs312f-g it has 2.9V cut off
what is the output voltage?
any reverse polarity protection to this tp4056 board if I accidentally reverse the 18650 battery to the battery holder???
thanks in advance
No there is not. Doesn't mean you couldn't add your own, fuse and diode.
any other method with buzzer & LED indicator warning??
4200mah 18650 😂
Seems like a great little board though, have ordered a handful. Thanks for the video!
learnelectronics Great video !
I want to ask you, Can I use it to power a 5V chineese wireless gamepad?
because I have one that runs on 3 AAA 1.5 batteries, and I want to convert it to a single LiPo rechargeable battery.
I would say yes, but I dont know for sure.
CAN YOU LIST THE REAL-TIME CLOCK AND MICROCONTROLLER
how long does the battery have before is no good? meaning they have no charge over time
That probably depends on the charge current used which is programmed by a resistor - usually 122 SMD = 12*102 = 1224 ohm. Which results in 900mA to 1000mA charging current. One can lower that - to extend battery life time via replacing the SMD resistor with a 2k or 3k ohm up to 20k and 30k which of course will result in longer charging times. The data sheet of the TC4056A gives more details about that on page 6 of the datasheet pdf datasheet.lcsc.com/szlcsc/TC4056A_C84051.pdf
Another youtuber made a video about replacing the current limiting charge resistor on a similar module
th-cam.com/video/oMez6wHsvC4/w-d-xo.html
Can you charge the battery while it is in use? Can you leave the usb plugged in all the time?
Ted Murphy yes it will charge during use and it will cut off the charge when the cell reaches 4.2V. so you can leave it plugged in. thanks for watching and taking the time to get involved and comment.
What is the output current?
can you use them for those small lead-acid leetec batteries?
Not. It is designed for Li-Ion only with a full charge level of 4.2V.
@@stinkycheese804 I see. Thanks.
Hello, great video! I have two questions..
1. I'm going to have 6 batteries charging with one charging board on each battery.... can I wire the boards output load in series to get 22.2v or 25.2v ??
2. Can us the batteries while they are charging?
HI, no you can't use them in series, but you can use them while charging.
Can i put a lipo in there like the one from drones
Can it be used on two 18650 batteries or just one..thanks
Just one
I know it's an old video, but it's there a version of this for three batteries in series?
The TP4056 is for one cell only.
I am looking for a way to charge 3x 18650 cells connected in parallel. Together they are still 3.7V but higher capacity. Can I use the TP4056 for that or is there a better idea? The battery pack is installed in an electronic project so I cannot take it apart to charge the three cells separately.
TP4056 board is for a single cell.

Does a boost converter exist to bring an 18650 to 5v? Everything I keep finding has a minimum voltage of 3 to 3.8v. I am reading that on some of them, if you go to low... they generate massive voltage spikes.
Try the Adafruit Power boost 500

@@learnelectronics Awesome, thanks!
Just for your own reference, check out this
www.ebay.com/itm/124367773290
That is my worry, I would check the voltage every so often, and then charge it when it hits one threshold. Another safety "check" could be put in for a lower threshold, for a total shut down, in case the first one fails.
Can i connect with 5v battery at output
Can I charge the rectangular batteries? They are 3.7v too, but why does the circuit says that is for the 18650 batteries?
Any lipo
Nice job .I all ready have one .best regards from Iraq my friend.
+ahmed gerges Thank you
does it power up the clock at 4.2 volt or 5 volt?
4.2
what is the output of it
It's ok to Lipo battery?
Do these circuits limit the discharge capacity of the battery at all? I know this video is a million years old, but I'm hoping you might see this.
Define "discharge capacity". Yes they have an output current limit around 3A (depending on ambient temp) and will shut down output if they reach their overheat trip temp. The datasheet may elaborate but generally if you need much more than 2A current, you should seek a board designed and rated for higher.
Question, I bought 2, 1 Lion and 1 Lipo. They look similar s how can I ell which is which?
I want to charge a cell phone LioN.
Same situation on my end, I have a dead portable speaker and I want to test by charging the battery to see if the original charge port is what fried.
Roy, you can use both. I just picked one and it charged my lion cell just fine. I took the advice of a commenter to my question on anther vid.
What are the red and blue LED's on the board indicating?
Blue power input, red charging.
The TP4056 cannot discharge batteries for storage. Do you know an intelligent battery protection PCB that can do that? That would be awesome!
It is not meant to discharge batteries for storage, nor is that all that important to do because they discharge themselves. Simply do not fully charge them. Besides, how long a storage are you talking about? For only a few years, the self discharge is too low to matter if they have a decent charge level. For longer, what was the point of even owning them? Plenty of devices last several years through regular use, which is far more demanding than mere storage.
You might be reading bad information elsewhere and drawing the wrong conclusions about the non-importance of discharging cells to some specific level prior to storage.
However if you really want to be picky about it, simply use the cells to power a load until they reach your target storage voltage. No need for a special PCB to do this. You could make it easier using a charger with discharge/capacity measurement function and just pull the cells out when they reach your target voltage.
Can i plug charger when load is connected?
Yes
Where do you solder the ntc to protect battery from over temp. ? If it doesn't have it, put it in the bin. If, yes, use the protection to save a fire starter.
can i use Micro USB TP4056 x 1 and li-po battery x 4 in parallel.. thank you
Yes, but with 4 in parallel they will charge at 1/4th the rate per cell so it takes a long time to charge them, and you still have the same peak output to load current limit that you would have using a single cell instead of 4 in parallel.
Im finding it near impossible to use something like this to balance charge 3 cells with protection for project, all those bms on ebay dont seem to work, any ideas ?
kermets you need one board per battery. It's doable, but not a great solution. Take a look at RC balance chargers...turnagy for instance. You can get 6 or 8 cell versions (you don't have to use them all)
thanks for reply, yes I have rc balancer for my hobby but they stop balancing once done and will not restart again if unbalance acquires, not the ones I have anyway,A lot of youtubers have ideas but havent found the answer yet.
Hi , the Dw01a switch off the lipo when the V = 2,4 V , but the minimal tension of lipo is 3V , why??
That 3V is arbitrary and depends on the manufacturer and cycle rating. Yes it would be safer and conservatively gentler to the cells to terminate discharge at a voltage higher than 2.4V, but they decided to set it at that. Many cells will survive this discharge voltage so check the datasheet to see what the cell manufacturer states about that.
what is max current output meaning using the battery not charging it
Francisco Sanchez that would depend on your battery
18650 battery 3.7 volts 6800 mAh
Thanks for the video. I’ve been using the TP4056 for my projects and although it works when the battery is plugged in and the load is attached, if the battery is detached with the load still connected and the reattached, the circuit has a probability of not turning back on. After reattaching the battery, I can disconnect the load and then reconnect it and it works again. I’ve tried adding a capacitor to the output of the TP4056 which reduces the chance of not powering on but it’s not a 100% solution. I was wondering if anyone else ran into this issue
could u solve this problem?
Hi @wywarren, I want to ask about the durability of this circuit when just charging the battery and connecting to the load. How long is the durability and is it stable during work?
Thank you
Can I connect 2 tp4056 load output in series to get a 7.2V - 8.4V output? Each tp 4056 would charge a single 18650 battery with only the output load in series to get a 7.2V to 8.4V.
You could but it seems kind of silly to do when 2 cell BMS boards exist and you would need two separate USB inputs for charging that are isolated (no shared ground or positive).
can these charge the battery and power the circuit at the same time?
Yes, that's a nice feature of this.
@@Turtlehands thank ya

I'm using 5V, 1A charger to charge and when connecting a 600mAh battery, it(TP4056) heats up within just 5 seconds.
From that output wire can we run a motor and led
+E - CREATORS yep
hi great video. if running a smaller battery like 300mah or 400mah, do we have to change the resistor on the board? the instruction manual for this board gives a table of the recommended resistors.
thanks
Can you upload the arduino sketch?
can you charge the battery when the load is connected?
No you can’t! It will damage the board or worse the battery
@@robinbpunkt2201 doing it since one year no problem until now
@@sblantipodi hm okay, but in the data sheet it says, you can’t charge and power something at the same time😄
@@robinbpunkt2201 can you link me to the datasheet please? Thanks

How do I wire more than 1 battery with these modules? I want to make 4 batteries in series, and I couldn't make the protection work
Jabberwock you can't wire more than one battery to a unit. if you want multiple batteries, you need multiple units.
learnelectronics Of couse I have multiple units. But when I try to wire between OUT- to another unit's OUT+ it wont work. However I think I might have an idea as to why. Common ground is the minus of input as well as OUT-. It could be the problem
Jabberwock sounds like a good place to start
If you want to build your own battery pack using for example 4x 18650 batteries in PARALLEL then I highly recommend using a dedicated module for that, on aliexpress com search for 'battery bank module'
One example:

can i charged several 18650 batteries simultaneously?
+norinco np no
How can you run two batteries in parallel and charge them?
Rodney, if you want to build your own battery pack using for example 2 or 4 18650 batteries in PARALLEL then I highly recommend using a dedicated module for that, on aliexpress com search for 'battery bank module. The TP4056 is only a charger board for 1 battery or cell... and it has _no_ boost converter.
One example: tinyurl.com/y8oul655
Can you charge AA batteries with this?
No, the voltage is too high
Thank you, I got one last question. If this charging board is capable of charging two 18650 batteries, what would happen if I charge three with it?
@@conquest222 slower charge time.....
how much volts on the output and what about amps?
The output voltage will be dependent on the battery. So somewhere between 2.75V to 4.2V. Output current is again dependent on the battery with a standard 18650 the maximum discharge current is 5200 mA .
learnelectronics wouldnt it be limited by the electronics?
can i charge 10 or 20 18650 battery in parallel?
+Saiben Alim no, it's for a single cell only
what I would live to see, is this hacked with an added photo resistor, if you do that forward me the video for multiple shares
