It work im so happy for making simple circuit for my project thanks.bro😊😊
This is exactly what I am looking for.Thank you.😊
This project is very good!
Thank you brother
Creative video, thanks :)
It's Awesome!
Really helpful circuit! Nice work :)
YOO ITS MAX
@@gabrielantiligando9905 Hey!
Very nicely explained. Keep it up. 👍
Hi! i was wondering if you can read the battey level with that 3rd connection
Nice.
So nice
Is good very good ;D
Agar Bhai Davod air led theater nhi LGA sakte ha
Good
Awesome
green led for full battery
What are the 2 transistors please
Haw you now is fuil charge?
very creative!!!! my question: some lithium barreries are for 3,8 V nominal, 18650 have 3,7V: could that be a problem??
a difference between 0.10v is not a big problem, it is ok to use with it.
Thanks!! I was looking for this to make a rechargable torch. My question is, How long does a single 18650 battery needs to full charge, and how will we know if it is full charged or not?
this circuit will auto cut when battery charge is full, but there is not indication of battery full , as it is made for those who doesn't have parts lying around him, and also making this is very cheap, charging time will vary according to the battery mah, you can leave it at charging for 1-3 hours it will not damage the battery.
@@CreativeInventorlab Thanks a lot.. 👍👍
some bms from samsung battery have no overcharge protection
RIP those☹️ Samsung batteries
Resistance value???
Will this work on new devices that has fast charge tech? I like to try this but having doubts co'z fast charging android battery bms can go upto 12v 3amp..
fast charging works when the battery is in the phone, when the battery is out of the phone, fast charging will not work, the bms is given to protect from over charge, discharge and deep dis charge.
careful of vervoltage when v >4.2 v your battery will be gone ;)
Question: how to connect: When charging and on de same time a load connected??
conect with the connection of charging output
Is it fine without the solder and resistor?
Yes
Merhaba efendim. Adaptör yerine bisiklet dinamosuyla şarj etmek mümkünmü? (6v 3w)

I looked for this USB connector om Aliexpress, but I could not find it. Where dit you get this?
from my city market
Bisides the + and - connection I see a thirth cupper connection. What is the function? Rgd, Jan

يتعذر التعليق لا أعلم .
does the led turn off when the battery i full ?
No
If you was to put magnets on the cables you would use same circuit for many batteries
How many hours it will charge bro?
depending on the the charger ampere and battery ampere, it will take 2-3 hours
How to covert 5volts DC to 7.4volts DC
does the security switch off automatically?
Yes
@@CreativeInventorlab شكرا in arabic
can we charge more batteries with this please answer
yes
Music nohi baat koro yaar
If we use same circuit to same mobile batary, will it work?
Yes
@@CreativeInventorlab thanks
Kitna time lagega charge hone mai batao?
battery ke capacity ke according, 2-3 hours, 1-hour me bhi ho skat hai , agar battery ka mah 1000mah ya usse kam hai.
1800 mah ka hai toh kitna hour lagega?
mera Intex ka battery hai 1400 mah ka usko charge hone me kitna time lagega?
Bro i think you have put the diode to the wrong way that silver colour should be in opposite direction
no, its in correct position
Can i use it to charge 5 batteries at thesame time?
its too many, connect them according to the battery mah, for example, if u have taken out that kit from a 4000mah battery then u can connect upto 4000mah battery, or connect 4- 1000mah battery in parallel.
But can I add more bms boards in parallel?
To 5640 lgana achga h ,,jo yeh bnaya h over charging 🔋⚡ se bchao nhi h isme bettry fat jayegi
What are the usb systems called
It is called micro USB female port
My lyf BMS has only 2 terminals please give the circuit diagram please 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻 help me sir.
you can use that also connections will be same, only positive and negative terminals are used
For some time it is good but for long term it is not right at all
It’s good for lifetime, if the bms circuit
Is working well.
Charager hone par kasa pata lagaga
waise charge full hone pad Power disconnect ho jayega, lekin saath me ek aur cicuit lagana padega, usse iske saath laga dene pad battery full hone pad indicate karrga.

Sir i want to replace LEDs like the red one in the video (which are normally on any electronic panel for on/off status) with higher capacity Numeric LED.
If you can do it Sir it will be great help
Battery full hai ya nahi hum kaise paatah kare
Battery full hone pad automatic charging disconnect ho jata hai
Bro please charging circuit ka link dedi😥
kaun sa ??
Apne battery charging ke liye jo use kiya hi
Bhai kya yeh work karta hai kya ? Please batao bhai
work karta hai
Koi aur no. Ka diode use kar sakte hai kya?
હા આ કામનું છે
@rajnandani4982 હા ડાયોડ માત્ર રિવર્ષ આવતા રોકવા માટે છે
sir kya yeh circuit lead acid battery ko charge karega.aur aap circuit diagram bhi diya kare.please.
yes, karega
@@CreativeInventorlab DHANYAWAD SIR.
Этот способ зарядки придумали ещё давно и я его проверял он убивал все аккумуляторы за 4 зарядки из за того что эта схема заряжает аккумуляторы очень быстро
How much is the voltage drop of the diode???
Usually 0.7V drops
No, in4007 drops 0.50 to 0.47 volts that means from 5v the battery will get 4.50v that's sufficient to charge
2 In4007 diode usually drops 0.6 - 0.8 volt = 4.4 -4.2v
@@cronos1675 good
Full charge ho jaega to kaise pata chalega
full charge ho jane pad bms khud se charger ko dis connect kar dega, jis wajah se agar charger laga bhi reh jaye to bhi battery pad koi nuksaan nahi hoga, battery full charge hone pad agar notification led lagane ke liye extra parts aur circuit lagega usse cost bad jayega, issiliye maine isme wo circuit add nhi kiya hai, ye circuit cheap and best hai, agar notification led bhi laga hai to uske liye hum alag se circuit bana sakte hai
I tried but always the light is glowing
bcoz that led work as charging indicator, the bms circuit will self disconnect the Charging 🔌 when battery 🔋 is full.
This is not the right way. This cannot protect the battery at all
Of you don’t have tp4056, then it’s only the cheapest right way and It already protects at all, much better than using just an diode.
Hi Sir. Is it possible to make a device to plug into any gadget that uses 3.7v battery (through the micro usb port) to check the voltage level of the battery? Maybe by using a volt meter or led light indicators. Because I have a few devices that uses 3.7v and very often I do not know the charge level of the device, and so only come to know that the charge is low when in use and have to interrupt the usage to charge it. If there were such a device (juggard) then I could regularly check voltage level so that I could plan the charging and not be disappointed at time of use.
Would love to see a video on this if it is possible. Thks.
Take a micro usb cable and cut whatever length you want from the end with the male plug on it. Then strip the wires to reveal the positive ( Red or Orange ) and negative (Black or Blue) wires and the data wires. Make sure your voltmeter is set to DC voltage.Then simply put the positive wire on your voltmeter positive lead and the negative wire on the voltmeter negative lead. You will instantly get the voltage reading. If you have a cable with 2 (Black or Blue) wires, one of them is an ID line used to tell what kind of device is being connected, it will have 0 volts and will not give you a voltage reading between it and the positive wire. It and the two data wires can just be cut short and taped up. They serve no function for checking voltage.
@@WayneBain Thank you bro. Will try and let you know how it works. Thks.
