3.7v Lithium Battery Charger Circuit | Very Easy 

I'm not an eletronics pro, just a very interested amateur. Videos like this, which distract with music and have no commentary to explain why certain devices are used in a circuit (and the rationale behind their choice), are meaningless. A truly great instructional video is one that can enlighten dummies like me, not prove its creator's cleverness to those who know electronics. I do understand the uses of resistors, diodes, LEDs, etc., but you need to explain (through commentary) how the ones chosen work in this particular circuit. Please note, I'm not questioning your ability to create interesting stuff, just your ability to explain things.

Actually i dont know how to use pcb board.... so thankyou... i like this.... channel.... 💚💚

3.7v batteries need 4.2v for charging not 3.50v

so.....the led is just a power-on indicator but not a full-charge indicator

These videos are so easy to follow!

3.5 v out put is not enough to recharge 3.7 lethium battery which shoing 4.2 v when it fully charged

Good project And use full project

I think the voltage to the battery should be 20% more than battery rated voltage. or not?

Thanks for this wonderful simple project .. it helps a lot.. .. but the didoe is heating .. ???

Thanks

Nice

Good instructions and nice video, very useful for me, is it over voltage protected?

Very very very nice bro

Input voltage is 6.46v and output is about 3.6v. How is it (about 3v.drop)possible using a diode.

Thnks man . Really nice. Good job

I was try this circuit & my battery explode, 1 diode can reduce voltage 0,4volt. If the input is 5volt, with 1 diode in series, output will be 4,6 volt.

nice

Nice job

This circuit output voltage is 4.6v. battery charging any problem

Simple but use full video.

Plz upload a video about 14500 battery charging circuit with auto off. Market only makes 18650 circuit but we need a good circuit About 14500 li ion. Plz guide us

Series me 16 cell 1 sat charge kar sakte hain 1 Wqt me pls reply

Good job 👍

Useful video 👍

I've burned 2 Li-On (for drone) battery with this diagram.. of course i recheck the connection after the first one blown, and it did it again for the second time. Any advice?

Neat presentation ..👍 thank you..

And how do you know when it's completely loaded?

Nice👍👍

म्यूजिक के जगह बोलकर समझाते तो अच्छा रहता।

It's really work

I made something like this. It is too slow. It takes "eternity" to get a full charge.

Use only tp 4056 module or ek he!👍

👍

Diode will get damaged after

Kitna bhi diod laga lo par circuit fail hai battery over heat ho jati hai

Can we use 10mm led

Daiod bahut hit hota hai

valeu

My 3.7 volt lithium battery charge only 5 min fastest charge...❤️

How will you know if the battery is fully charged?

Sir,how can charge 3.7 v dc Battery. Shawon form Bangladesh.

Good but not auto cut off.

This circuit not can reduce the voltage to 3.6 volt, it's fake.

4.2 !!! Charge

Bro mobile ki 3.7 volt battery battery kitne samay me full charge hogi mere pas multimeter nahi hai

Lipo battery charge ker sakty hein 3.7 v wali

bro..its very very slow..or it will charge battery only 10% ... Yeh circuit battery ko only 10% se 30% hi charge karata hai..chahe isse mahine bhar ke liye hi laga lo.... Aagar isse 5v with 1Amp input denge, toh ye diode Aapake only 3.5v dega but 1amp nahi dega isse sirf 10mA se 100mA hi output milata hai..our 3.7v battery ko charge karane ke liye at least 4.2v hi jaruri hai..so aapako input 3.8 se 4.2 hi rakhana jaruri hai.

What's the use when you can just buy cheap tp4056 charge modules and its protected

Thanks brother. Can I glow led bulb from this circuit? Please brother

Does the LED turn off when charging ?

The voltahe is too low for recharge a 3.7 v battery

I tried with 5.15v 2amps charger and the voltage steps up to 6v,why?

Hey bro, is the input power supply from main power socket. U didn't show.

Can I put 2 resistors of 330 ohm in series? (I don't have 1k resistor)

Please tell

Diode became very hot, why

How do you get 5v supply first show that

you connected battery +ve to diode -ve, can we do that?

Sir the diode becomes hot whats the reason behind it and please give the solution

Is it 100% working 🤔🤔

Value of diode? sir

Desordenado

Esto reemplaza modulo de carga?

No explica que ohmios es la resistencia,malísimo video

can it charge a 12v lithium battery?

haaa very funny i got out put voltage 7 volt wich damage my lithium ion battery its a fake video

Hello bhaiya 1.2v lithim battery charger kaisa banayga

Dimag hi kya

diode damage after 5 days

🙂

good video

Sir diode bhot heat ho raha hai mene same procces follow kia

и чоо ?

its very simple and i already know this. the aligator clips are charger. lights indicates because of charger. Without charger it will not indicate. ...if charger removed, indicator will off, the flow from negative to led are ok but going back to positive is impossible because rectifier diode negative polarity blocks it and it can only enter positive charge. which means indicator only indicates only for charging nothing more. So he doesnt create any charger.. or any..... or something. maybe the title must be "how to make a charger indicator"?

Kitna der charge karna h

Bhai2,3 parallel battery ko kaise charge kre

Good

ye kya he bhai koi logic he

There is not such thing like a "3V led" in the entire universe.

G

the zener diode does all the job. Is nothing significant this video.....just nothing....sorry

यज्ञरयब

Fake

Bro mobile ki 3.7 volt battery battery kitne samay me full charge hogi mere pas multimeter nahi hai

Good
