si funciona el proyecto pero el problema es que las resistencias de 4.7 k y 220 hotmios tiene tolerancia no es exacto cuando lo mides y solo prende el led que dice qie ya esta cargado la bateria por eso le e puesto en lugar de las dos resistencias de 4.7k 2.2k y en medio de estas resistencias e puesto un trimer de 4.7 k y regulando el trimer ya funciona bien.
I built it but it doesn't work 1 when the green led turns on, the mosfet is not blocked 2 output I have 5 volts which are much more than the 4.2 maximum of the 18650
@@danielemencucci9931 It happened to me too, but here is the solution: You might have figured this out already, but if you solder the jumper wire towards the 15k resistor (right side) of the bottom intersection, and you solder the negative lead to that, BOOM it starts to work. Don't ask, I am dumb for these things, I just LEGO -d the charger together...now I just need to wait for the 3,7V batteries to arrive from China :D
Very good solution :) I have just began to gather the parts needed. When it comes to the TL431 component, I only found a TL431CZ or TL431ACZ. They are good too right?
@@homemade_101 Hello again! The million dollar question: I put together the charger step by step. Should the green light be ON, when I plug it in, without a 3,7v battery connected? Also I measure 5V az output voltage. Shouldn't it be lower? Thanks in advance for the reply :)
It doesn't work. There is an error or part of the video is not clear I installed everything exactly as planned, but the result is... The green LED works non-stop even though the battery is weak, and the red LED lights up very weakly and does not turn off and does not glow brighter.
Sir,please send me a video of pure sign wave inverter..i wanna use it for my tv and electric fan..thanks,im ur follower and im waiting for ur response.😊

Excellent video, but I couldn't get this IRFZ44 MOSFET or the other MOSFET IRF3205, so are there other alternatives please? Thank you very much
Yes you can use it.
Very very impressive- from syoknyadiy channel...u will become my idola
The practical input connection and out put connection soldered is not matching with circuit diagram connection shown in the beginning. Pl clarify.
Don't think about thumbnails. watch the video bro.

hello,I don't understand the 15k resistor on the red led and the 5.6k resistor on the green led,aren't they too high?were 1k not enough?
try to apply 1K.
I built it but it doesn't work 1 when the green led turns on, the mosfet is not blocked 2 output I have 5 volts which are much more than the 4.2 maximum of the 18650
when the green led lights up on pin 3 of the tl431 i have 2volt and not 0v so the mosfet is not blocked

Welcome, TL431A

Darn... don't mind me....I soldered the jumper wire on the wrong place :D
Good video you can share the Schematic diagram
1:42
Which thing you used here
Is this a copper wire
yes
*You make the battery charger circuit 18650 3s full battery it automatically disconnects charging ? please make it*
Use 3S BMS 👉 th-cam.com/video/r6pANFg_TOM/w-d-xo.html
Or
Use chargeing module 👉th-cam.com/video/lVMrDvIUxc0/w-d-xo.html
Its not charger
nice job ❤️ ....
Thank you..✌️🔋
Поставь по входу +5в резистор 1,5-2 ом и все хаработает
What if I used 3 lithium battery in parallel connection? Is it ok ?
Its ok. But i recommend use Charging module.
How many battery (mah)use?
3.7v all
3.7 v laid acid batary charge hoga
yes
I can use BC547 0:45
Can't bro only TL431
Swap the 5.6k resistor for a 1k and you will have a brighter green led.
thank you
hello friend make a 110 volt smde pure wave inverter please
✌️✌️
Não gostei montei o circuito e não funcionou.

Ok I will try
