Интересное решение. Можно добавить пищалку для оповещения об окончании заряда акб.

[@sakibsarwat5064]

can it charge 5000mah also shouldnt it be 4.2v when fully charged?

[@CreativeTechos]

Yes, absolutely it can charge, and charging te may be little longer

[@AnekSingh-p3h]

Battery ke fix 4.2v hone chahiye tab battery 💯 percent hoti hai aagar batter main 4v honge toh 80 percent battery hogi

MUY BUENO GENIO ,MI PREGUNTA ES SI SE PUEDE CARGAR DOS BATERIAS 18650 EN PARALELO CON ESTE CIRCUITO

[@enriqueatala2567]

Hola, no contesta mucho este genio, el tema de dos a la vez depende que esten descargadas igual, como asi tambien igual marca, etc... es mas, este circuito debería ponerse un diodo a la salida positiva hacia la bateria ya que puede sobrepasar toda la carga hacia el circuito, hay muchos videos mostrando el peligro que puede ser cargar varias juntas, consejo carga de a una o hacete dos circuitos idem. saludos

[@einnarrodriguez4027]

La idea de cargar en paralelo es menos peligrosa que cargar en serie, pero como dice el otro comentario, es recomendable cargar una pila a la vez, solo por seguridad, saludos.

very very good video ❤❤❤❤❤❤ but ,can i use 13007 instead of 13005?

[@ardisaja5687]

can it use for powerbank or smartphone?whats must be modified

[@shashiji27]

Nice, circuit. Your multimeter is very good please give link for purchase this type multimeter

bhai 1.2 volt nimh battery charge karne ke liye kya modification karna parega is circuit pe?

[@CreativeTechos]

That will require a different circuit, I'll try to upload that video ASAP

[@vishalgautam7319]

MJE13005 ki jagah bc546 transistor laga sakte hai kya

[@arjoena1807]

nice video, did u hv simple auto cut for 2s lithium battery video? thx.

Bro it is too nice it will get for us for volt two battery

[@ramonfermin85]

Saludos una pregunta es posible hacer el mismo circuito usando el transistor 13003 ya q no cuento con el 13005.? Gracias de antemano

[@nildadantas5902]

Pode ser com um tip 41c

How many 18650 batteries can be charged in parallel with this circuit and what is the max amp output of this circuit??

[@amitkhobragade1977]

Hi... Can you place a link to buy the Multimeter you use.? Thanks.

[@mtiger8]

Good work
If I do not have 13005 Transistor
Is there an alternative to it ??

[@CreativeTechos]

You can use any NPN power transistor, but take care of pin outs as different transistors have different pin configurations. 13005/13003 has pin (1 Base, 2 Collector, 3 Emitter)

[@albertodiseno1973]

Muy bueno 👍

Sir can I use w431 instead of TL431 #please #reply

[@darjusz56]

hello, why 4,08V ? 4,12-4,15 is be fine and better and secend question help me and show mi how do thi but 20,5V :(

[@asddgsasdg]

so this circuit autocut off battery when is full charged ?

Could you redesign for Lifepo4 battery cell (3.65 Volt) Thnx.

[@aazartechnocreative6666]

I like your work

[@CreativeTechos]

Glad to hear that, Thanks for watching 🙂

[@gunalan4949]

Can it be used for charging mobile phones?

[@CreativeTechos]

Nope, only charging battery directly

[@tanmay6725]

Osm dear 💕

[@CreativeTechos]

Thanks for liking

[@Funnymovementbd]

I can use bc547 or bc557 transistor

[@ECircuits]

how many ampere charger use ?

[@CreativeTechos]

You can use minimum 1A and max 3A

The 13005 transistor is overheating when connected to the battery.

[@jasonpanugaling]

Can we add more batteries to this circuit?

[@CreativeTechos]

This is put current controlled, suitable for single battery

[@lawalmohammed83]

Please Sir, what changes required to upgrade the charger to charge 8.4v lithium ion batteries?

[@thomasheredia447]

Those dont exist?

[@sumitnarkhede.3105]

sir you are make very well battery.charger.but sir plese lead acide battery charger make only for transistor and capacitor 4.2 volt cutoff voltage.

[@Whitebear80]

Can you give a list of parts?

[@valdirenegomesfagundesdoss1471]

[@أحداث_تاريخية]

I have a power supply charger for cameras, and its capacity is 12 volts - 16 amps. It has a variable resistance to raise and lower the voltage. Is it suitable for this project?

[@CreativeTechos]

No, you actually need to use 5v 2-3A mobile charger

[@MrErickpe]

Excelente

[@kirangupta7364]

Can we leave it overnight charging?

[@electronicsideas1361]

Which transistor used??

[@CreativeTechos]

MJE13005 NPN Transistor, You can use any NPN Transistor, let me know which one you have?

Buenos días hice los dos tipos de cargador de batería 12v que aparecen en los vídeos pero ninguno marca cuando la batería está cargada alguna solución o que hice mal ?

[@retrogamer790]

Bro i didn't get 4.1 volts as output from it . I only gets 3.6 volts what can i do . What's the problem 😢😢 plzz..... reply plz...

[@CreativeTechos]

Try to check transistor, or tl431 ic

[@awantown2003]

I hope you can teach me how to make it

[@awantown2003]

Dear can you make 4.1v 10a solar charger

[@AdamTheBot]

What's the maximum amp output ?

[@CreativeTechos]

400ma max output current

[@AdamTheBot]

@@CreativeTechos You have a great creativity in yourself . But it's just a waste of time and money tp4056 would cost around like 0.25 USD .And it will give 1A output and if you modify it just by changing resistor it can give 2A output the.

[@yousefLa52.]

The Anode is not working I don’t know why???

[@CreativeTechos]

Try another TL431 Shut Regulator ic

[@yousefLa52.]

@@CreativeTechos please give me an alternative for Tl 431 ❤️

[@petersack5074]

Appears, to be a ' comparison ' circuit; the transistor switches off, when its' voltage, is the same as the INPUT voltage....

[@mukeshsharma4063]

Kindly uplode 3.7x2 mean's 7.4 volt battery charger with auto cut off Circuit Diagram.

[@CreativeTechos]

No worries, I'll try to upload asap for 2s & 3s too

[@zinthuaung2606]

Can I charge 6 pcs battery?

[@MACYNET323]

How much is charge current?

[@arunk8663]

Charging would require 5V from source, in this circuit there will be a lot of voltage drop then how can the battery be charged ?

[@CreativeTechos]

This circuit requires 5v dc and output voltage is dropped to 4.2 v using TL431 shunt regulator and 680R resistor, with limiting current with 47R.
It requires 4.2v to charge a 3.7v lithium batteries.

[@INCREDIBLE-INDIANS]

What is the ampere of this charger?

it would be nice if you explain the circuit logic. great video anyway

[@CreativeTechos]

Thanks for appreciating and watching, 🙂

[@KannaA237]

Follow the Video not schematic diagram, it's a little bit confusing, in video LED common pin to 470 ohms to 431 pin 1, in diagram it varies

[@adityajat587]

Bhai first transistor kon sa hai aapne value to bataye hi nhi

[@CreativeTechos]

Any power transistor can be used, i used 13003 also small one is TL431 shunt regulator or we can say a adjustable zener diode

[@nipundeewantha4033]

Do I need to change the circuit to add 3 batteries to this circuit?

[@CreativeTechos]

Since this is current limited circuit, you can connect 3 batteries in parallel, but it will take longer to full charge them

[@popau3151]

sir, is it possible to use the TIP41c transistor?
