How To Make A 3.7 Volt Battery Charger With Battery Fully Charged Indicator. in Home Made

Hi Friends, Today i will show you How to make a simple 3.7 volt battery charger with fully charged indicator etc.. easy to make at home...
Friends in this video I will show you How To Make A 3.7 Volt Battery Charger Circuit With Battery Fully Charged Indicator green nd red LED ..Friends the circuit is very simple usefull and you can easily make the 3.7 volt battery charger circuit at your home..Friends you can charge li-ion nd Lithum 3.7 volt battery and lithium 3.7 volt battery by this circuit..Friends the 3.7 volt battery charger circuit diagram is in the video please see the circuit diagram..Friends in this circuit we will use two LED ( green nd red ) as indicators,,the green led as circuit on indicator and the red led as battery level indicator..Friends if there is a little charge in the battery the red led will glow brightly..When the battery charge will increase the red led's brightness will decrease accordingly,,,and when the battery will be fully charged the red led will be off..Friends in this way the circuit will work..So friends if you want to know how to make a 3.7 volt battery charger circuit at your home then watch the video and follow my instruction and please see the circuit diagram...Thanks...

Hi there!!! I would like to make a charger 3.7Volts 4000mAh can you tell me the values of all the components please. Many Thanks for your help

[@kobie1585]

good job, Boss.. i want to know how many cells can u charge with this circuit, or its meant for one cell only?

[@ishbhasin5279]

Same to same 12 volt battery full charge and lo charge cirkit making please .

[@sumitnarkhede.3105]

sir kya ismain 6 volt ka input dekar 4.2 volt output le sakt hai.aur sir bc 548 ka output to sirf 100 ma rahega.isaka current badhane ke liye kya karna padega.agar hum inp main 1 se 2 ampear bhi denge to ismain hamain jyada current output main nahi milega.plese sir bataye.

How to blink any one of LED bro??I added a strobe light circuit to the LED terminals..but its not blinking

[@ahulyavlogs5398]

Bhai Main kit Banaya Sara Kuchh Achcha kam Kiya I am so happy but Mera Kuchh question hai Main Apne Samsung ke charger Se Jab Mein lithium-ion battery ko charge kar raha hun to charge ho rahi hai but bahut Garam ho ja rahi hai hit kàr ja rahi hai........usse safily or 5.0 volt ko 3.7 volt mae transfer kaise kare yae bata do ....bhaijaan .......plz

Can I use 20 k preset

[@thePurushTube]

How does this cutt off charging when batery is full? and how is charge current limited when battery is directly connected to supply? I it not dangerous with out these ?

[@SanuKumar-jl2mr]

Agar hme 1.2v battry k liye bnana ho to kitne ohm k resistors lagege..??

[@sahilkashi7535]

Sar ful charge hone per per auto cut hota hai kya isase mobile battery charge kar sakte hain kya please reply

[@rahulyadavjitechnical6599]

Bel 48c kam kare ga

[@barcleymomin271]

Study the circuit diagram, without any components the battery is getting direct the input voltage. This will only damage the battery.

[@elbinv]

You are making different circuit from circuit diagram..in diagram its green LED connected near to variable resistor

[@ShivaKumar-re1hl]

Why green led positive connected to transistor collecter terminal, but in diagram is different

Video 8:43 time me kaha negetive ko transister ke collector ko jaodna hai our uss se pehale transister ko 220 ohm resister lagay hai and green led ka possitive pin lagaya hai ye kya bhai

[@edifierbass7821]

Good day, will it stop charging after reaching a full charge ?

[@barcleymomin271]

Never!
