Brilliant ideas. But in the second circuit, can the max voltage threshold be lowered to 4v, to charge the battery to around 80% only? Is that what the 10k pot is there for? Thks.
The first two circuits only behave as voltage indicators, the first one undervoltage and the other overvoltage. The third circuit is specifically made for 4.2V, but could be modified to charge to lower voltages. Just be sure to have a fuse installed in case the transistor fails. All circuits shown can be modified, for example I made an undervoltage indicator that is set to 15V.
I've used the first one👍 thanks
Very cool circuit, thanks.
I just want to ask what current flows through the circuits? Is it possible to regulate the current?
Awesome 👍😊👌 bro keep it up and love from BANGLADESH 🇧🇩🇧🇩🇧🇩🇧🇩🇧🇩
Wonderful
This is very amazing sir
Как всегда отлично
O Hello re Hello
Hola el primer circuito de 2.6volt sirve balancear los super capacitores de 2.7 volt 500f
hi, just want to ask if the circuit no. 3 also act as overcharged protection on the battery?
Amazing,My dear bro.Thanks.
First is awesome.make a new circuit for 3S low voltage indicator
3rd Circuit me 5v se work kare ga sar
Very good video
Really good ideas
I like your projects, but in the last construction, it is not noticeable when the led is off or on !

Super👌👌💯💯
jo bhi project banate hai uska circuit diagram bhi upload kariye please
Please u,make,a 18650 Lion battery chager with,number ---2
Connect a,battery..plz...plz
cool and useful bro
Come si collega alla batteria per caricare progetto n.2
Can I use 10 k ohms resistor in place of 10 k preset??
Well done bro
Nice
Thanks to circuit diagram
Isso é show de bola!! Valeu!! Obrigado. Brasil
Achei que eu tava sozinho 😂 até que enfim um comentário em português kk
+1 BR 😎👽👍🏻
Algum de vocês conseguiram fazer esse projeto?
@@soldadoferido1929 👀👀
@@canalfacavocemesmo5800 eu não fiz não. Eu só assisto mesmo, só monto alguns
Please show the name of the circuit & the circuit diagram for a bit more longer period of time.
i tried 2nd Circuit 4.2v led inductor circuit but led is not glowing.. what is the problem
Bro ,is the circuit fail ?
Sir ,iam in Kerala. 12v battery test not shown
saludos kapoo!
Bahi🍺❤🍺
hey is it possible to contact you privately?
can you show me the calculation part
А можешь собрать схему 3.7 в например с945 или s1815 tip 122
Earphone Audio Single clip light video please.
High sound clips light indicator. Use transistor 5volt ,
3v led , audio signal around 1-3volt.
You not mentioned in the 3 number the transistor name which is D882
bagus keren
Nice video g to bahi aakhri vidio main aap be kis number ka transister
Akhri transistor ka bomber D882

Bro i tried to do your project its not working help me bro
