When you consider the range of tools used here, the result is pretty good. Nice with a DIY video without the use of CNC, 3D printers and other expensive machines. Good job, and good explanation.
Very cool project. I probably would have tried to make it possible to take it apart and change stuff, all the glue is somewhat permanent. But when I first saw it I did not think it was wood.
When I first saw it . I thought it was 3d print! Nice job. Mine takes up about 1 sq meter! And only charges 12 cells ! And discharges 3 cells. Nice! Have you thought about using some thermal sensors in a silicone gel or something to get the charger/dischager to shut off if the cells get hot? I was getting up mid night for batt change. And put a cell in back ward twice. I started using more light when changing cells. Trying to charge and test 100's & 100's of fast as I can takes a long time. So I got up mid night for cell change for two months plus. I have 98 to go. Then time to get more! I only need about 10,000 cells with 2.5-3.0 ah each. (2600-3000 mah each.) In a 29.4v 7s bank. It's gonna take time!!!! I'm only like 1/100th through that at best. I guess about 5k cells would work. But what's wrong with excess!!! Nice video!!
Great video as Always!! I think that everybody will agree that the best part was about the "spaghetti sandwich". (7:18) dont get me wrong all the DIY project is great !!! Sorin, keep creating us amazing projects!
Thank you for this video. I liked your approach to the charge/discharge issue. I don't know which I hate more, hot glue on the fingers or two fingers stuck together with super glue. Keep broadcasting!!
I just love this 18650 charger project even more than your last one. When I first saw the thumbnail to this video I though it was a textured 3D print. Nice work! Again, you've got balls of steel to solder smd circuit boards with a 100 watt soldering gun. Oh, and now subscribed and rang the bell.
Un proiect excelent! Felicitări Sorine. Circuitele de încărcare le.am testat si eu, sunt foarte încântat de ele. Cred ca ma voi apuca de proiectul asta in concediu.
You have a great project, but I thought of a addition, how about a voltage and tempreature connections to a Nano then to the computer so you can monitor and record these parameters. I connect 4 leads to the positive poles of the battery and 4 thermisters to the battery holders mounted in such a way as the press against the batteries. I am writing a sketch to monitor these valuse and send them to a computer useing putty. If you want more info let me know.
wow awesome. Could you make one that lets you set the voltage to charge to or discharge to? I know lots of people that would love this and if you put a kit together I'm sure you would get some community support :)
Very good project. I like it a lot. One difference I would do though - Get rid of the blue LED's. I would have charging as amber LED's, and when fully charged, use green. Even better the Gallium Phosphide green which is more of a yellowish green.

i just hook up everything directly for the meantime: the battery to a usb voltmeter in between, and the resistor. it doesnt have a cut-off so im closely monitoring. i just want to discharge it, also at 3.59v while under load using 10w10ohm i am only drawing 0.29 amps. would you recommend a higher resistor value to speed up the process? its already running 3 hrs 39 mins and so far the total mah drawn were only 1071 mah

thanks a lot! now i have something else i have to make with the batteries i have lying around. As if i didn't have enough projects i'm working on already :)
Can I use only one TP4065 to charge severel battery? I mean, if I connect 2/3 battery in parallel and charge them with single TP4056 module, is there any problem?
hi. with 4 charging modules you can charge 4 cells individually. the cells can have different capacity, they can be discharged to different levels. you can put each cell in the charger at different times. all the cells will be charged much faster, with max 1A. not 1A divided to all 4 cells. if you want to charge multiple cells with only one charging module, the cells must always be connected in parallel (when you charge them and when you use them). the cells need to be the same type, same capacity, same lifespan, same charging-discharging cycles and they will be charged 4 times slower -> 1A/4=250mA each cell.
hi. yes you can charge them like this. but you need 3 different power sources for the TP4056 modules. not 3 switch mode chargers, because they will be connected to the same supply current from the mains. you need 5V chargers made with transformers, or a transformer with 3 isolated 5V outputs.
Excellent presentation, educational and well spoken. Beautiful tool, too. I like the wood. I'll need to watch a few more times with pencil and paper! A schematic would be nice for those us climbing a steep learning curve..;- )
Robert Thomas He sais 6 dollar for every unit (wich is 4 times) 24 dollar, that is without the wood, glue, wiring etc. Do you know the amount of various 18650 chargers you can buy at AliExpress for 24 dollar? Save yourself the trouble i would say.
Taunter Atwill I bought for 8.50€ (9$) a double usb battery charger for AA, AAA, 18650, 26650, 18500 and more, which works with usb/pc or wall. But no display, only green or red leds. For 12.90€ double battery plus decharging function, or for the same 12.90€ a 4x slot. This DIY isn't very cheap but it's nice. I would build one, if i could understand if i may install a spring as size adapter and use it for any kind of batteries...... Once you buy a 10x pieces of a component, and assembly only 4x, you spend the same amount of money for a 4x or 10x!
Salut Sorin. Am un laser pointer driver defect(am incercat dioda laser la curent continuu si functioneaza) . Un MOSFET cu marcajul "T4L" caut dar nu am gasit pe internet nimic. Poti sa-mi spui ce as putea sa folosesc care este compatibil, sau un link?

Adding a spring or size adapter, can you use it to recharge/discharge any kind of batteries (like AAA, AA, 1,5v, 3,6v) or it will works with 18650 batteries only?
@@Sorin_DIY Thank you, so it means "it will not works for 1.5v", I have to disassembly laptop batteries and mobile phone batteries... (PS: i saw your power bank video too, I assure you that it will be littler and lighter if you install old some 3500-4000mah mobile phone batteries instead 6x 18650) And soon i'll build the power supply! Thanks so much!! PS: you can find the same components for cheap in other websites (IE: Mini voltmeter for 0,75$ instead 2,51$ each)
I noticed that the schematic did not include the led indicators for the charging and fully charge, was wondering if it would be included, I'm confused, But nice build!
Hi sorin ,I made the same chargeras per your old one , but i cann,t charge 4 cells at one time with a wall pluck charger . only one at time , how to charge 4 cells at one go , what do i need to do further .. tks
hi. did you connect the supply wires to all the charging modules? if you connect it to a usb charger, but without any 18650 cells, the blue LEDs on all 4 charging modules should lit up.
Hi Sorin thanks for your swift reply , Yes i did connect the charging wire supply to all the connectors , but cann,t charge all the four cells at one go. only notice that the red charger lights one ,two at times the 3rd charger lights fliking . but works well with one cell ,, supper good ,
Ba Sorin ! Esti destept , bravo ai creat un incarcator de baterii complicat si l-ai facut sa para simplu , dar accentul in engleza ma zgarie pe creer rau de tot !!! Ea si mai practica ,
Mi ics melt the hot glue after some minutes. They are charging fine, but they get too hot to the touch. 1 amp is being applied. Is this normal? The batteries I have are new and old, so I think they are fine.
hi. it's normal for the TP4056 IC to get hot, while charging with 1A, but not enough to melt the hot glue. hot glue fixes the circuit board to the panel, the circuit board should not get that hot. you can use a small self adhesive heat sink on the IC.
@@Sorin_DIY Thanks for the response. Mine do get really hot. You cannot touch it after some time. I had to put a heat sink on it so it did not melt. Any hot glue I use close to it, went melt in seconds. The IC charges well and is the only one so far that gets really hot. Another one gets hot too, but not that much. Weird.
Salut Sorin.Pot face doar doua circuite dar numai de descărcare și fără încărcare?!As vrea sa am doar pentru 2 acumulatori dar numai descărcare ca am deja cu 4 sloturi de încărcare..ms
hi. if you put the battery in the wrong way in a charging module without protection, the charging module will be destroyed. I did not try this yet for a charging module with over discharge protection. I will try it for a future video.
Yes, reverse polarity (putting the battery in the wrong way) will instantly kill the TP4056 chip. The protection on the board he used is only for battery over-charge & over-discharge. It does not protect from battery reverse polarity. You can add a mosfet protection circuit. Check out a good video about this from Afrotechmods.
0:26 but i thought that you can't wire all the tp4056 with the same positive wire because it short circuit the battery ?? You told me that in a comment a few days ago...
that was on the 4S BMS charger video. NO you cannot connect TP4056 modules in series and use the same charger for all of them. but YES you can connect these modules in parallel and use the same charger.
@@Sorin_DIY Thank you master i have made the newbie mistake of the parrallel / serie !!! I wish there was a way to plug them in serie. I know you can isolate the supply but it kind of expensive to add a BO505S for each TP4056...
Hi Sorin ,i am very much interasted in this project , i have all the parts except the heat resisters ,can i use a 10w 15ohms rs instaed ofthe 10w10ohms ..your advice plaease thanks ...
hi. yes you can use the 15ohm resistor. but the discharging process will take longer. when the battery voltage is 4.2V, the 10ohm resistor is discharging the battery with 420mAh. with the 15ohm resistor - 280mAh
hi. with 4 charging modules you can charge 4 cells individually. the cells can have different capacity, they can be discharged to different levels. you can put each cell in the charger at different times. all the cells will be charged much faster, with max 1A. not 1A divided to all 4 cells. if you want to charge multiple cells with only one charging module. the cells must always be connected in parallel (when you charge them and when you use them). the cells need to be the same type, same capacity, same lifespan, same charging-discharging cycles and they will be charged 4 times slower -> 1A/4=250ma each cell.
hi. you can use it to charge any type of li-ion cells, that have a nominal voltage of 3.6V or 3.7V and a maximum voltage a 4.2V. and you can charge some li-po cells too, that have the same voltages. you just need other connectors or battery holders for the cells you want to charge.
@@Sorin_DIY so no 1.2 v ni-mh batteries then (( thnk you for the impressive video and your answer. I hope one day u will teach us to build a charger for all aaa. Aa li-ion etc batteries
hi. yes, you can connect 2 cells in parallel to one charging module. if the li-ion cells are new, it's better. you can also do this with old cells, but they need to be the same type, have the same capacity, same life-span, same charging cycles and use them in the same parallel configuration.
If they're all down to about 2 volts per cell only, they're likely quite bad already. I mean like he discharged it down to 2.5v per cell, that's already too deep of a cycle to do usually. You normally wouldn't want to get them lower than ~3.5v or so for them to last long. You can still charge them (carefully, monitoring if they don't get hot), and some may be salvageable with like half their capacity or so. With luck, a bit more even.
hi. you can try to revive them with a battery charger. you need to set the charging current to max 300 or 400 mAh and charge the very slowly. check them very often if the batteries get hot. if they do, while charging them with this small amount of current, the batteries are not good anymore. after they are fully charged, you deposit them for 2-3 weeks. then check the batteries voltage. if it's more than 4.0V, the batteries are still good.
Can i have tips on making these DIYs? I have a fear that my battery (prismatic) might explode or catch fire, or i would get electrecuted because i dont know much about these but i do really love to learn about, can i have some tips?
hi. if you want only to charge the cells, you need simple switches with 1 pole and 2 positions. the negative wire from the 5V charger is common. is connected to all TP4056 modules and all the voltmeters. the positive 5V wire from the charger is connected to all the voltmeters and to the switches. each switch will deliver the positive supply wire to 1 TP4056, so you can turn them on individually. the voltmeters sensor wires are connected to each li-ion cell positive terminal.
Ciao Sorin. Complimentissimi. Iscrizione e Like. Per pura didattica, cosa va aggiunto al circuito per poter conoscere anche la capacità e la resistenza interna delle celle? Extra: Perchè quando cerco di saldare, pur usando il flussante, spesso mi si formano delle palline di stagno che non si attaccano? Uso un saldatore economico da 15€ impostato sui 350-450 gradi e uno stagno 60/40 1mm. Attendo fiducioso la tua cortese e competente risposta. Buon Anno. Antonio
hi. I don't have it anymore. the drawing was made in ms word but not with the exact dimensions, but only for reference. I marked the exact dimensions directly on the plywood.
hola excelente vídeo , hay alguna forma de saber la capacidad descargada en amp, total de cada celda? mencionas que la descarga con esa resistencia va desde los 450mha pero baja con relacion al voltaje de la calda , es ovio pero daría un estimativo con relación tiempo , de la capacidad total hay algo mas exacto de forma casera que no sea arduino ? agregándole transistor q haga variar la resistencia así a medida que baja el voltaje .mantenga los amp de descarga , gracias y perdon no hablo en ingles saludos
Hola. para un cargador de celda DIY 18650 es difícil medir la capacidad exacta. Puede agregar un módulo de prueba de capacidad barato de China. Otro método impreciso es agregar un convertidor reductor, bajar el voltaje de la celda (de 4.2 ... 2.5V) a 2.5V estable. luego conecte una carga de 10 ohmios. consumirá 250 mA hasta que la celda se descargue. digamos 6h. multiplica 2.5V * 0.25A * 6h = 3.75Wh. divide 3.75Wh al voltaje nominal de la celda, que es 3.6 o 3.7V; 3.75Wh / 3.6V = 1.04Ah. pero esto es impreciso, porque la eficiencia del convertidor reductor varía según el voltaje de la celda. cuando el voltaje de la celda se está reduciendo, el convertidor extraerá más corriente de la celda para mantener una salida estable. entonces su eficiencia fluctuará probablemente entre 95-85%. así que en realidad la célula tendrá 1.1Ah o 1.2Ah ...

Me encantaría poder replicarlo, deseame suerte para que funcione!
👍
Nice work, Sorin!
Great video! Thanks for sharing
Very nice project, thanks for sharing
your calculations very completed... good luck for you brother 👍
THIS!!! is perfect for my drill battery restoration shop :D

Should use a aluminum base plate as a heat sink. That way you can enclose the enclosure
Very accurate and nice as well,good job 👍
thanks a lot! now i have something else i have to make with the batteries i have lying around. As if i didn't have enough projects i'm working on already :)
Damn , you are a genius
No Einstein was a genius, Sorin is a pro DIY'er.
Nice videos man! Keep them coming. I’ve been looking for an 18650 diy charger :)
One last question, what is the polarity of the led pins on the Tp4056 Board and why can you use only 3 wires each?
hi. the LEDs have a common anode. the polarity on the board is (- + + -). the positive connections are in the middle.
Can I use only one TP4065 to charge severel battery?
I mean, if I connect 2/3 battery in parallel and charge them with single TP4056 module, is there any problem?
hi. with 4 charging modules you can charge 4 cells individually. the cells can have different capacity, they can be discharged to different levels. you can put each cell in the charger at different times. all the cells will be charged much faster, with max 1A. not 1A divided to all 4 cells. if you want to charge multiple cells with only one charging module, the cells must always be connected in parallel (when you charge them and when you use them). the cells need to be the same type, same capacity, same lifespan, same charging-discharging cycles and they will be charged 4 times slower -> 1A/4=250mA each cell.
Newbie question. Would this charger charge Ni-MH batteries? Like the Ikea LADDA 2450 AA batteries? Thanks!
no. only li-ion and li-po cells with a nominal voltage of 3.6 or 3.7V and max 4.2V.
Thank you for responding.
Hi I would like to know if I can put 3 18560 batteries in serie and charge each one with a tp405 in parallel with the batterie.
Thank you very much
hi. yes you can charge them like this. but you need 3 different power sources for the TP4056 modules. not 3 switch mode chargers, because they will be connected to the same supply current from the mains. you need 5V chargers made with transformers, or a transformer with 3 isolated 5V outputs.
Excellent presentation, educational and well spoken.
Beautiful tool, too. I like the wood.
I'll need to watch a few more times with pencil and paper!
A schematic would be nice for those us climbing a steep learning curve..;- )

He sais 6 dollar for every unit (wich is 4 times) 24 dollar, that is without the wood, glue, wiring etc. Do you know the amount of various 18650 chargers you can buy at AliExpress for 24 dollar? Save yourself the trouble i would say.
Taunter Atwill I bought for 8.50€ (9$) a double usb battery charger for AA, AAA, 18650, 26650, 18500 and more, which works with usb/pc or wall. But no display, only green or red leds.
For 12.90€ double battery plus decharging function, or for the same 12.90€ a 4x slot.
This DIY isn't very cheap but it's nice.
I would build one, if i could understand if i may install a spring as size adapter and use it for any kind of batteries......
Once you buy a 10x pieces of a component, and assembly only 4x, you spend the same amount of money for a 4x or 10x!
Salut Sorin. Am un laser pointer driver defect(am incercat dioda laser la curent continuu si functioneaza) . Un MOSFET cu marcajul "T4L" caut dar nu am gasit pe internet nimic. Poti sa-mi spui ce as putea sa folosesc care este compatibil, sau un link?
Can you post a charger for 4 batteries connected serial (giving 14.4 volt together) that is used for the drill
my next video will include what you need.
@@Sorin_DIY Ciao Sorin. L'hai fatto ? Antonio
Lo pego con rexina, le puso gotita instantanea , Pegamento de mezcla, lo dejo de tal manera pegado?que la suma de tiempo trabajado y de espera mas materiales mas plaquetas?...vale mejor la pena comprarlo por que si se comete algún error y deja de cargar una PLACA DE CARGA?????.....Bs As Argentina
Adding a spring or size adapter, can you use it to recharge/discharge any kind of batteries (like AAA, AA, 1,5v, 3,6v) or it will works with 18650 batteries only?
it works with li-ion and li-po cells with a nominal voltage of 3.6 or 3.7V and a max voltage of 4.2V.
@@Sorin_DIY Thank you, so it means "it will not works for 1.5v", I have to disassembly laptop batteries and mobile phone batteries...
(PS: i saw your power bank video too, I assure you that it will be littler and lighter if you install old some 3500-4000mah mobile phone batteries instead 6x 18650)
And soon i'll build the power supply! Thanks so much!!
PS: you can find the same components for cheap in other websites (IE: Mini voltmeter for 0,75$ instead 2,51$ each)
I noticed that the schematic did not include the led indicators for the charging and fully charge, was wondering if it would be included, I'm confused, But nice build!
Great job, Sorin.thank you
Hi sorin ,I made the same chargeras per your old one , but i cann,t charge 4 cells at one time with a wall pluck charger . only one at time , how to charge 4 cells at one go , what do i need to do further .. tks
hi. did you connect the supply wires to all the charging modules? if you connect it to a usb charger, but without any 18650 cells, the blue LEDs on all 4 charging modules should lit up.
Hi Sorin thanks for your swift reply , Yes i did connect the charging wire supply to all the connectors , but cann,t charge all the four cells at one go. only notice that the red charger lights one ,two at times the 3rd charger lights fliking . but works well with one cell ,, supper good ,
hi. try it with another charger. preferably a minimum 2A charger.
Thanks will try it that way
Ba Sorin ! Esti destept , bravo ai creat un incarcator de baterii complicat si l-ai facut sa para simplu , dar accentul in engleza ma zgarie pe creer rau de tot !!! Ea si mai practica ,
How about reverse polarity protection? These little boards are not protected.
Great video btw
Diodes & Fuse too... Better Safe Than Sorry
Mi ics melt the hot glue after some minutes. They are charging fine, but they get too hot to the touch. 1 amp is being applied. Is this normal? The batteries I have are new and old, so I think they are fine.
hi. it's normal for the TP4056 IC to get hot, while charging with 1A, but not enough to melt the hot glue. hot glue fixes the circuit board to the panel, the circuit board should not get that hot. you can use a small self adhesive heat sink on the IC.
@@Sorin_DIY Thanks for the response. Mine do get really hot. You cannot touch it after some time. I had to put a heat sink on it so it did not melt. Any hot glue I use close to it, went melt in seconds. The IC charges well and is the only one so far that gets really hot. Another one gets hot too, but not that much. Weird.
Salut Sorin.Pot face doar doua circuite dar numai de descărcare și fără încărcare?!As vrea sa am doar pentru 2 acumulatori dar numai descărcare ca am deja cu 4 sloturi de încărcare..ms
salut, da se poate.
Hey how to make a box for all de stuff
can i use my volt meter that only have 2 wire red and black only??
yes. but when it's measuring less than 3v, the LED display will be less visible. that type of voltmeter usually measures between 3.5 - 30V DC.
Sorin - DIY Electrical Nerd thankyou....
If you accidently put the battery in the wrong way, will it destroy the tp4056 board? I fuse my tp4056 boards
hi. if you put the battery in the wrong way in a charging module without protection, the charging module will be destroyed. I did not try this yet for a charging module with over discharge protection. I will try it for a future video.
Yes, reverse polarity (putting the battery in the wrong way) will instantly kill the TP4056 chip.
The protection on the board he used is only for battery over-charge & over-discharge. It does not protect from battery reverse polarity.
You can add a mosfet protection circuit. Check out a good video about this from Afrotechmods.
Excellent project
Pretty cool I'm not going thru all that but I would have done something different for power and if you are worried about heat a fan
The fleaker is a fature! Not a bug!
Sorin please make it to battery analyzer 18650 to read mAh no load
Would it be easier to use female terminal for switches?
I don't think so. you still need to solder the wires to the terminals and it will take more room inside the charger.
@@Sorin_DIY You're right, and if you don't shrink wrap them, perhaps when you bend the pins you can short the terminals by mistake?
thanks for sharing! keep up the hard work
0:26 but i thought that you can't wire all the tp4056 with the same positive wire because it short circuit the battery ??
You told me that in a comment a few days ago...
that was on the 4S BMS charger video. NO you cannot connect TP4056 modules in series and use the same charger for all of them. but YES you can connect these modules in parallel and use the same charger.
@@Sorin_DIY Thank you master i have made the newbie mistake of the parrallel / serie !!!
I wish there was a way to plug them in serie. I know you can isolate the supply but it kind of expensive to add a BO505S for each TP4056...
Whatever in the world happened to cable ties for wire management?
You work to hard brother good knowledge 👌👌👌👌👌👍👍👍👍👍 nice video
Awesome Video... Make a video about 3s, 4s, 5s with battery protection board.....
ronaldo luarca
You make it lazy fucker!
Hi Sorin ,i am very much interasted in this project , i have all the parts except the heat resisters ,can i use a 10w 15ohms rs instaed ofthe 10w10ohms ..your advice plaease thanks ...
hi. yes you can use the 15ohm resistor. but the discharging process will take longer. when the battery voltage is 4.2V, the 10ohm resistor is discharging the battery with 420mAh. with the 15ohm resistor - 280mAh
Can we not use just one charging circuit for all the cells??
hi. with 4 charging modules you can charge 4 cells individually. the cells can have different capacity, they can be discharged to different levels. you can put each cell in the charger at different times. all the cells will be charged much faster, with max 1A. not 1A divided to all 4 cells. if you want to charge multiple cells with only one charging module. the cells must always be connected in parallel (when you charge them and when you use them). the cells need to be the same type, same capacity, same lifespan, same charging-discharging cycles and they will be charged 4 times slower -> 1A/4=250ma each cell.
can we use it for charging other batteries ? or anyways to update it for doing it ??
hi. you can use it to charge any type of li-ion cells, that have a nominal voltage of 3.6V or 3.7V and a maximum voltage a 4.2V. and you can charge some li-po cells too, that have the same voltages. you just need other connectors or battery holders for the cells you want to charge.
@@Sorin_DIY so no 1.2 v ni-mh batteries then (( thnk you for the impressive video and your answer. I hope one day u will teach us to build a charger for all aaa. Aa li-ion etc batteries
whats your opinion on using 1 module for charging two similar -brand new batteries ? thanks
hi. yes, you can connect 2 cells in parallel to one charging module. if the li-ion cells are new, it's better. you can also do this with old cells, but they need to be the same type, have the same capacity, same life-span, same charging cycles and use them in the same parallel configuration.
Does not include the LEDs in your schematic. Can you please include it? 🙏
the LEDs are from the TP4056 modules. you can use the original LEDs, or you can replace them on the modules. there are 2 LEDs with a common anode.
@@Sorin_DIY Yes I got it, I mean the LED below the small screens that connect to a 10 ohm resistor
that LED is shown in the schematic, it's connected in series with the 1Kohm resistor.
@@Sorin_DIY thank you sorin. 😊
Nice job dude
I have 20 old laptop battery but he was out put 2 volt only can you tell me what's problem?
If they're all down to about 2 volts per cell only, they're likely quite bad already.
I mean like he discharged it down to 2.5v per cell, that's already too deep of a cycle to do usually. You normally wouldn't want to get them lower than ~3.5v or so for them to last long.
You can still charge them (carefully, monitoring if they don't get hot), and some may be salvageable with like half their capacity or so. With luck, a bit more even.
hi. you can try to revive them with a battery charger. you need to set the charging current to max 300 or 400 mAh and charge the very slowly. check them very often if the batteries get hot. if they do, while charging them with this small amount of current, the batteries are not good anymore. after they are fully charged, you deposit them for 2-3 weeks. then check the batteries voltage. if it's more than 4.0V, the batteries are still good.
Thanks
can i use two pcs. of resistor 5watts 10 ohms in parallel?
no. they will become a 5ohm 10W resistor and will get very hot. you can use just one 10ohm resistor but with a big heatsink.
@@Sorin_DIY salamat po?👍
best of the world, never seen it before
Can i have tips on making these DIYs? I have a fear that my battery (prismatic) might explode or catch fire, or i would get electrecuted because i dont know much about these but i do really love to learn about, can i have some tips?
Thanks for this great Video, i will build this thing for sure.
If i want the charge feature only, how do i have to connect the displays?
I don´t understand the schematics with the wirering of the switch also :(
hi. if you want only to charge the cells, you need simple switches with 1 pole and 2 positions. the negative wire from the 5V charger is common. is connected to all TP4056 modules and all the voltmeters. the positive 5V wire from the charger is connected to all the voltmeters and to the switches. each switch will deliver the positive supply wire to 1 TP4056, so you can turn them on individually. the voltmeters sensor wires are connected to each li-ion cell positive terminal.
@@Sorin_DIY Thank you, that helps quite a lot :)
Ciao Sorin. Complimentissimi. Iscrizione e Like. Per pura didattica, cosa va aggiunto al circuito per poter conoscere anche la capacità e la resistenza interna delle celle?
Extra: Perchè quando cerco di saldare, pur usando il flussante, spesso mi si formano delle palline di stagno che non si attaccano? Uso un saldatore economico da 15€ impostato sui 350-450 gradi e uno stagno 60/40 1mm.
Attendo fiducioso la tua cortese e competente risposta. Buon Anno. Antonio
Very good video, I love the details.
Great work like always. Can you upload the drawing to the front panel?
hi. I don't have it anymore. the drawing was made in ms word but not with the exact dimensions, but only for reference. I marked the exact dimensions directly on the plywood.
I like your diy projects. Students could learn alot from your videos
very nice. i will try my self to make one like this. love from Pakistan
hola excelente vídeo , hay alguna forma de saber la capacidad descargada en amp, total de cada celda? mencionas que la descarga con esa resistencia va desde los 450mha pero baja con relacion al voltaje de la calda , es ovio pero daría un estimativo con relación tiempo , de la capacidad total hay algo mas exacto de forma casera que no sea arduino ? agregándole transistor q haga variar la resistencia así a medida que baja el voltaje .mantenga los amp de descarga , gracias y perdon no hablo en ingles saludos
Hola. para un cargador de celda DIY 18650 es difícil medir la capacidad exacta. Puede agregar un módulo de prueba de capacidad barato de China. Otro método impreciso es agregar un convertidor reductor, bajar el voltaje de la celda (de 4.2 ... 2.5V) a 2.5V estable. luego conecte una carga de 10 ohmios. consumirá 250 mA hasta que la celda se descargue. digamos 6h. multiplica 2.5V * 0.25A * 6h = 3.75Wh. divide 3.75Wh al voltaje nominal de la celda, que es 3.6 o 3.7V; 3.75Wh / 3.6V = 1.04Ah. pero esto es impreciso, porque la eficiencia del convertidor reductor varía según el voltaje de la celda. cuando el voltaje de la celda se está reduciendo, el convertidor extraerá más corriente de la celda para mantener una salida estable. entonces su eficiencia fluctuará probablemente entre 95-85%. así que en realidad la célula tendrá 1.1Ah o 1.2Ah ... (google translate)
Another very nice project, that i will reproduce in the future 😁
