This is not a charger you should use. you have to think about safety. an automatic intelligent charger with over current, volt protection is recommended!
enough for those who want to make their own
Oh yes, but you forgot about temp control! The most important for Lithium and likely for any chem to not do explosion, as well polarity check. 😺
It must be better done with MCU and PWM pumping at least, ideally with ΔV control. 😼
I'm totally understand channel author, but spreading ignorance not help anyone, be it better a incourage to learn! 😺
Is charging stop when battery is full?
Ye circuit 12V 24v 36v chargee me use kar sakte hai
Brother which Soldering Kavya You Have
How many of you have built this ? How do you lower cut off voltage? It charges my 18650 to 4.5 volts
Thats normal, because this "Circuits" from such kind of "Channels" are garbage ^^
Is it a slow charger?
Instead of resistors R5 and R6, you put a 10 K potentiometer. Adjust the cut-off limit from there, using an adjustable voltage source adjusted exactly to the voltage you want to switch to.
@@ionutzionutz7106 how do I confirm the cutoff voltage is where I want it to be without fulling charging the battery?
@@ashtonmclaughlin6106 The voltage setting threshold is made with resistors R5 and R6. Adjust from there.
We should also have a limitation of the charging current, this does not exist on the diagram. If we have a very discharged battery, the initial charging current is high and is not limited by anything.
Grato!
Show de bola, projeto, vídeo, didática e explanação e também pelo esquema que sempre disponibilizou!
Abraços, saudações!
clair , net , avec un beau schéma en plus !
Over discharge protection?
if i change the values of resistors can i charge 12V acid battery. THANK YOU
yes, there are samples in the rest
Make this circuit for 3S lithium ion battery also. I liked this video. Unique 👍
Only BMS
ypu can't charge a 3S battery (= 4.2*3 = 12.6V ) with USB charger :. It's only 5 volts .... You must use a boost step-up converter for this ! A BMS is madatory !
@@renelefebvre53 use a rise converter - it is necessary, but this will not be enough. for the 3S scheme, the use of balancing is mandatory. so that the batteries are not discharged to 0 volts, a BMS is needed. recharging also needs BMS.
Hocam MOSFET in değeri farkeder mi 49 ah veustüolarak
So, can you explain how to calculate R value for tl431?
loi d'ohm / Ohm law it's simple !
@@renelefebvre53Explain it then.
Czy ładowanie tego ogniwa ustanie z chwilą zapalenia się zielonej diody?
Muy bueno
Hocam 450 W lık PC Güç kaynağının 5V luk çıkışını kullansak sıkıntı olur mu?
PC güç kaynaklarında 5v olan bölgede AMP. Değeri yüksek gelebir hocam zafer usta okursa cevabı verecektir selametle
@@sinanyc.2105 Teşekkür ederim.
@@SilentDream1 Sağol usta. :)😇😇
Love your videos! thank you !!!
Sayın zafer yıldız kardeşim iki adet şarj kesmeli 3.7 v devresini yaptığınız gibi monte ettim kendim TV tamircisiyim hata olayı yok ama devrelerin ikisinde çalışmadı şarj ediyor ama kesinlikle şarjı kesmiyor
Macar malı cihazın devresini yaptım o da tl 431 li orjinal size öneririm
Kısa devre ters bağlantı otomatik kesim mevcut..
Thanks for sharing
Emeklerine sağlık ustam ❤️👍🙏
Teşekkürler Sinan bey
@@ZAFERYILDIZ52 asıl teşekkür ederiz ustam bu kadar emek veriyorsun zaman harciyorsun genç kardeşlerimize ışık oluyorsun Allah'a emanet olasin selametle ustam 👍👉❤️👈🌹🌹🌹
Can you show me 12v batt charger sir?pls send me the link if you have.. thanks
Big project recharg batery litiun, 👍👍👍
k3569 ka use kar sakte hai
You have such creative ideas
Bu devreyi 7.4 volt da kullansak yine çalışırımı?
I know the question was a bit old, but maybe it's useful to someone... It can work at any voltage, the maximum is in the TL431 datasheet and the same for the mosfet. To do the same at other voltages, the voltage divider formed by R6 and R5 must be recalculated
You should explain how it works!
same here, probably he's just making a DEmo not tutorial
MERHABA ZAFER BEY SEVEREK TAKİP EDİYORUZ .tl431 yerine başka ne kullanılabilir.kolay gelsin
Tam seri imalat yapılacak iş olmuş kolay gelsin
Valla benim aklıma gelmişti fakat tp4056 dan pahalıya geliyor😢
12v 100 AH Battery Charger Circuit
I wish i your future videi, you'll make 3.7 charger than can charge 3 battery at the same time..i found few to other channels but i forgot them..sokhran✌️
Zafer can you make a crystal radio work with no electric
İşte usta dediğin böyle olur
Схема супер, но мастер, становится барыгой!
Зачем в транзисторе 2 сопротивления вместо одного? Правильно, что бы покупали 2 номинала по 50-100 штук))))
Было бы очень неплохо включить в эту цепь ещё и устройство отключения разряда батареи ниже опасного порога напряжения разряда.
Emeklerine sağlık ustam ❤👍🙏
Доброе время суток! Можно ли использовать IRFZ24
Este cargador es lento pero la ventaja es que no se calienta y no calienta la batería, muy buen cargador.
Entonces creo que sí me sirve para carga solar con una celda
Thank you sir
چرا نقشه مدارهاتون را نمیزارید
So nice thanks sir
Браво, следя, велик си, поздрав от България
Kindly uplode 3.7x2 mean's 7.4 volt battery charger with auto cut off Circuit Diagram.
Mantap 👍
SUPER
12v200Ha battery auto cut no off Ac 220v charger circuit
Nice good
circuit explanation? words?
R3 = 15k - ? .... , R4 trimmer resistor .... , Z44N = P55N
Labdien! Šī ir vecā shēma! Šeit atkal nav strāvas ierobežojuma? Viss iet pa taisno!!! Vajag ielikt ķēdē vismaz 1Ω rezistoru, lai ierobežotu kopējo strāvu! Cik mA Jums tur ir uzlādes sākumā, ja akumulatoram būtu aptuveni 3,4V?
süper
Master
Bom
Мартентиговый обман. Реклама радиоэлемеентов. Схема проще, но добавляя детали берут деньги))))
Oh come on man you could have measured the the voltages its just a demo
Эта схема была год назад...
👍👍
اوکی 👍
👍
3s bms 12 volit 😢
👋👋👋😉✌️😊
ممكن تشحن تلفون
Your schéma is funny but bad for use . Use a TP5046 chip, it's make for , and integed security .....
Reply plz
fake
