Bro in thumbnail its shown +charger- , so obviously its 14v dc that when you connect light will turn off and at the same time battery will start charging, You can use higher amps both diodes to charge battery faster

Sir i tried this and its working perfect as in video. But there is a delay while switching to battery mode. Around 5 to seconds. When the charger line is off, the 12v led glows after 8second delay. Why is this happening.
It is due to 1k resistor that is responsible for turning transistor on and off also the transistor is used not more powerful, so i recommend to try power transistor like TIP41C & use 470 ohms Resistor.
Very nice and very easy circuit.. congrats to you sir for your valuable activities
Thanks for watching my friend 🙂
I will always be on this channel. Love it. Keep creating!
Thankyou so much for appreciating
Well done 👍 and many thanks
My pleasure 😊
Muito bom o circuito. Porém ele carrega muito lento a bateria . O que fazer para o carregamento ser mais potente? . Pode ajudar?
Use the power transistor (high amp rated) also use 3a diodes instead of 1n4007
Nice 👍👍👍
Thankyou
Good job bro
Thanks 🙂
@@CreativeTechos Bro can you make a gold detector ??? But detect only gold Please reply or uploaded making video please
Will the battery get charge by using 12 volt 5amp adapter as supply in this project
Yes you can use but replace 1n4007 diodes with 6a diodes.
@@CreativeTechos Thanks a lot for your valuable feedback
If the voltage is 3 volts, does it need to be changed or not??
Sir iwant to ask it may used for 4volt light
Yes connect 4v battery with 4v light
I like learn too this electronic lessons
Good
Thankyou
...great 😀👍
Can I connect it to my solar panel (12v) as a charger ?
yes since the battery is 12v
Thanks bro .. is this circuit work with a 4.7v lithium battery
can you pls make it with auto on / off using relay + tp4056 module + brightness controller
Left side connection wires or Ac wire or dc wires
Bro in thumbnail its shown +charger- , so obviously its 14v dc that when you connect light will turn off and at the same time battery will start charging,
You can use higher amps both diodes to charge battery faster
In stead of 12v want to make 6v 3A dc to dc what changes to be done
I'll provide you schematics without relay, WhatsApp me +91 9596386458
Also please you may watch the new video i uploaded today
Hi which tranistor is that?
D882 , or you can use any NPN power transistor, do check the pinout configuration first
Plz make inverter led tube light circute transformer less power supply
How many Watts?
@@CreativeTechos 20 watts with battery protection circuit
Right side connection is from battery left side connection yellow and red is DC r Ac

Is it rechargeable?
Yes, it will turn off led in automatic mode and also start charging battery.
Whit 5v led is ok?
Any scheme for 3,7v bateray?
Same will work for 3.7v.
Connect 3.2v light instead of 12v also use 4.2v input dc to charge battery
can i use D 880 Transistor
Nice

@@CreativeTechos okay thanks for tour reply, will try that and update
Sir make same circuit for 12v dc fan
👏👏👏👌👌👍
Thankyou
How much voltage is there in input voltage
14v input dc to charge battery
@@CreativeTechos thanks for your valuable feedback
My pleasure👍
Which type of battery do you use for this project details plz
I used 12v lead acid battery 7.5ah
✌✌
Thankyou
No overcharge protection I guess
Its just automatically on off light for power cutoff also i added function of charging as you may have seen in small lanterns lamps
Bro can you make a gold detector ??? But detect only gold Please reply or uploaded making video please
100 volt dc how to reduce 12 volt dc plz make circuit 2 amps
From what you're getting 100v DC?
@@CreativeTechos led tube light blast out put is 100 volt dc .make 12 volt how to make
100v , check out how much out put current
@@CreativeTechos 700 m ampir current
Ok I'll try to upload ASAP
4v circuit please
I'll upload ASAP
@@CreativeTechos thanks
My pleasure 🙂

How to connect this circuit at 6 volt battery
Hi
👍
It's safe to keep battery connected to charger without cut off?
Its safe to leave charger connected with battery using this circuit
😘
Where is the schematic
this circuit is not perfect because the battery is continually charging and inject a small current in full charging .

I love this channel. How can I download the circuit diagram and discription?
Thanks 😊, you can check video description download link is in description
Good
Thankyou
