Very nice👍👍👍👍👍👍 video thank you
amazing idea, thanks😊😇
Fanstastic work 👏👌 thanks my friend👍
Abi mukemmel proje olmuş eline emegine sağlık
Thank you so much!
Eline sağlık. 👍👏👏
Thank you Sir.
amazing idea ❤❤❤
thx my frend
eline sağlık hocam
Very good. Just a little thing: I downloaded the diagrams from google drive and the BD140 is wrongly connected, the collector is switched with the emitter. In the video it is connected right.
Good project 💛💛💛💛💛💛

I intend to make a flashlight with a 15w lamp using a 3.7v rechargeable battery and with a converter circuit from 3.7v (DC) to 127v or 220v (AC) .... all this inside the flashlight. That is, recharge the battery and have the converter for AC inside the flashlight. Can you help me with the circuit ? But is has to be a simple circuit without a board, because I don't understand electronics. Thanks.
Eline sağlık Zafer hocam, bu devre 1.2 v NiCd ya da NiMh bataryalar için pot ile ayarlama yapılarak uygun hale getirilebilir mi? Bir de Lion piller yüksek akımla şarja başlar, adım adım akım düşürülerek şarj tamamlanır diye duymuştum bms devreleriyle. Böyle sabit akım ile şarj bataryaya zarar verir mi?
BMS şarj etmez seri pillerde şarj olan pile daha fazla enerji gitmesini ve aşırı deşarja karşı yine tüm hücreleri korur . ancak devreyi ayarlayıp 1,2 volt seviyesinde kullanmak mümkün saygılar.
So nice
Excellent!
Я благодарю тебя
really great idea
thank you so much
Zafer bey, Bir motorun yönünü belirlenmiş bir mesafede tersine çevirecek bir devre varmı yaptığınız? Selamlar
Çok başarılı bir çalışma olmuş, eline sağlık. 08:02'de şarj bitince 4.17V sonuç alındı. Bunu 4.20 Volt şarj edebilmesi için devrede nasıl bir değişiklik yapmak gerekir? Mümkün mü?
Zafer ustam/hocam acaba bunu normal telefon için de yapabilir miyiz?
Класс. Побольше класных видео
The Ni-Cd batteries 3.6V died in my portable home phones (5.8 GHz). I bought Li-Ion batteries for 3.7V - 800 mA and would like to replace them there by soldering directly to the contacts inside these telephone handsets. But there are 12 volt power supplies and I would like to assemble a simple but at the same time effective circuit for switching from 12 volts and charging these Li-Ion batteries. This scheme on the video seemed to me too complicated due to the large number of elements. The question is - is there any controller for charging Li-Ion batteries on which it would be possible to assemble a simpler circuit?
നല്ല അറിവ്
We can make everything with TL431 and you can use a relay instead of the transistor so there no need to use Heatsink mate! Anyway it's a great circuit for 18650's 👍
yes, your observations are correct, thank you for your comments and support.
@@cym247 if you know how a transistor works then u should know the configuration of a relay, they're so similar.
@@cym247 transistor work as a switch

Great 👍👍👍
I thank you
У меня в телефонах домашних переносных (5.8 gHz) умерли Ni-Cd аккомуляторы на 3.6V. Я купил Li-Ion аккомуляторы на 3.7V - 800 mA и хотел бы их там заменить припояв прямо к контактам внутри этих трубок телефонных. Но там стоят на 12 вольт источники питания и я бы хотел собрать простую но в то же время эффекитвную схему для перехода с 12 вольт и заряда этих Li-Ion аккомуляторов. Эта схема на видео мне показалась слишком сложная по причине большого количества элементов. Вопрос - а существует ли какой либо котроллер для заряда Li-Ion аккомуляторов на котором можно было бы собрать более простую схему?
هل من الممكن استخدام تلك الدائرة مع بطاريات السيارات ١٢ فولت
Super!
teşekkürler kardeşim
Thanks buddy, how about adding low battery cut-off to it?
а можно увидеть схему низковольтного трансформатора Теслы?
Bi tane bataryanı 3.7 v sharge etmek mantıklı. 2 ve ya daha fazlası olursa balance etmek gerekiyor, yoksa çabuk bozulur. Sebebi şu .ardıcıl bataryalar (li ion) sharge zamani biri birinden farki sarge oluyor. Mesela biri 3.7v öbürü 4.6v göre bilir. O yuzden bataryalar bozulur😉

Hi, I need to charge more than 2 cells. I need to charge 6 cell of 9800mAH. What changes do I have to do to achieve this?
🔥🔥🔥🔥🔥👍
5 voltu 12 volta çıkaracak devre yapabilirmisiniz Zafer hocam
can this circuit do the balancing?
Can we use this circut with 12 V bat.
Que buena idea!!
Puede hacer uno para baterías de litio 48v?
Puede ser en el futuro gracias por los comentarios y el apoyo
To make a charger for 48 volts is much more complicated. First you will need a power supply that provides more than 50 volts with a compatible current capacity. By my calculations a 48 volt lithium battery should have 12 lithium cells connected in series or, for more current, 12 packs each with 2, 3 or more cells connected in parallel. So the charger should limit the battery charge to 4.2V x 12 = 50.4V, if the 12 cells or packs are working properly and balanced. Probably the battery must have a BMS already built in. The problem is that the TL431 has a 37 volt limit and op amps like the Lm358 usually have a 32 volt supply voltage limit. The simplest system is a traditional regulator with a high power NPN transistor with a good heatsink, a zener diode or several associated in series with voltage between 49 and 50 volts with the anode connected to ground and the cathode fed by the power supply through of a resistor calculated not to exceed the maximum dissipation of the zener(s). The collector of the transistor is connected to the power supply, the emitter to the battery and, between the cathode of the zener and the base of the transistor, a resistor that must be determined experimentally. This resistor will limit the base current and the battery charging current will be equal to the base current multiplied by the hfe gain of the transistor. The lower the battery voltage, the greater the charging current and will drop to zero when the battery voltage approaches 50 volts.
@@andreascarl6428 Muy amable por su explicación y su tiempo, lo tendré en cuenta. Gracias
Where can I order from and it's easy to order this PCB.
2 projekt fajny, ale brakuje ograniczenia prądu ładowania! Nawet nie zostało pokazane ile on wynosi?
The Q3 transistor in lm386 circuit diagram is it NPN or PNP ??? If NPN so there is a mestak in diagram
It's PNP but it's connected wrong in the circuit diagram, the collector is swapped with the emitter. In the video it is connected correctly with the collector connected to the +Vcc of the battery

Hy bro can i charge 2s battries in series ... is that safe for battry health
Video nun 1. Bölüm ünde 2s yaptı dikkatli izlerseniz ayrıntıyı çok turlu potansimetre ile ayarı 8.4v. yükseltip 2s şarj yaptı 👍😉
As long as you do not charge the batteries with high current, it will not be a problem. Do not exceed 1 amp for serial charging and make sure the batteries are of identical capacity. Finally, before starting to charge with such circuits, equalize the charging start voltages of the batteries, for example, both batteries should start charging at 3.5 volts, one of which is 4 volts and the other is 3.5 volts, which creates a problem in the long run.
@@ZAFERYILDIZ52 ok👍🙂

Таким способом можно заряжать только новые аккумуляторы и не более 80% заряда.
Зарядка должна проходить постоянным током, а потом постоянным напряжением. Здесь только постоянным током...
Y el diagrama?.

@@ZAFERYILDIZ52 ссылку на плату в алиэкспресе можете дать?
второе зарядное собранное на плате не может работать ! схема платы не совпадет со схемой по ссылке, и расположение деталей тоже не соответствует схеме !
It is not fair to charge batteries at 8.4V without a BMS.
One battery can be charged with 4.3V and the other with 4.1V.
And the charging current is very low 0.4A.
The other circuit with 431, is OK .
Not a good idea at all to charge two Li-Ion cells in series ! If the cells don't have the same capacity, one will overcharge (with a fire hazard) and the other will not fully charge !
Each cell must be charged individually
