6volt emergency lightme same components use kar saktahu? Auto battery charge hoga?6 voltke liye kitni voltki adopter use karna chahiye kindly bataiye.thank u for your nice vdo

[@realproject6398]

which transisiter use

[@alwincecil4887]

Is battery is automatically charging in presence of power supply..?

[@miteshdhanani]

As u have shown we have to connect it with adapter can we connect it with 3w 6v solar panel

[@CreativeWorldPro]

for that , you have to use 6 volt led light

[@miteshdhanani]

That’s fine

[@subhahan8706]

sir can i use "12 volt led panel and 12 volt adapter". "It can work or not" for this circuit, please give reply sir

[@varun07ch67]

plz suggest a idea about desoldering pot

Can I use mospec transistor sir please answer

[@CreativeWorldPro]

what is mospec transistor ?

[@miteshdhanani]

Can we connect it with 3w 6v solar panel

[@CreativeWorldPro]

sure

[@mongelaloe2304]

does it also works on 12v system? what should i do to make it work? thanks

[@CreativeWorldPro]

for that you have to use 12 volt LED

@@CreativeWorldPro thanks, i'll try it someday, don't really have the time atm.
