THANK YOU FOR WATCHING.
Wow..... music is very good,.. like-marry party love music😂😂
Thanks for watching dear.
Don't we need current limiting resistor for led strip?
It need a 4056module to charge batteries.. A mobile charger wouldn't work..
yes bro not work charger .
mobile charger not charging battery So dont Try it.i suggest 4v battery
I've been following you since 2016 and you have a great job I did not have time to thank you so now i say THANK YOU
So I wish you the best
Thank you so much dear. I am glad to hear you. God bless you.
that's really cool.. I didn't seen it on my home page. thank you for sharing..
Thank you. It's first time on the Internet.
Science & Technology Experiments how much time these batteries take to charge
It takes 2 hours for fully charged.
czcams.com/video/1GUKI5_B0S8/video.html
please watch
my led panel is heating too much on directly connecting to 4 volt battery solution plz
Ek 100 ohms ka resistor series men lagane se voltage kam kr k heating kam ki ja sakti hy mgr jb battery low ho jaegi to brightness bhi kam ho jaegi.
islye heatup hone den aur kuch hi time bad battery jab 3.5 volt pr ajaegi to heating kam ho jaegi. Resistor na lagaen to acha hy.
Can I have the link for this led plate? Thank you
Sir Lithium ion battery se direct led bulb jala sakta hai .Agar battery 24V aur 18 ah ka ho to
Will it work on 1w 6v solar panel with the tp4056 module for charging the cell?
yes it can work.
Science & Technology Experiments thank you.both come about a $.can be very handy and reliable for street vendors
Thanks for comments again.

you must use protection circuit between lithium battery and charger
There is a video how to get free charge protection board on my channel. Pls get & use if you are making it. Thanks.
DEAR i astonished when you put diode and resister with one another , after that you cut the Resister and then cut it ..... be care full in future..... dear really you done a best job to make a rechargeable light.... thanks
It was mistakenly connected there & instead of re-recording the video, sI display message on screen to rectify. Thanks for comments.
You actually did a big work! But how to get rid of overcharging problem! or how long is the charging time
DC motor ka kasimabad
lekar de dijiye
i love this video......but agar aap circuit daigram bhi dikha dete to thoda or clear ho jata......mera ek question h ki....jab ham charging karenge tab hame pata kaise chalega k battery full ho gaya h ya nhi
As u have done it if we want to connect it with 3w 6v solar panel then instead of electric
It will charge.
Bro what is the benifit of diaod in this circuit as nokia charger already have it to regulate voltage?
Diode doesn't allow return voltage and voltage flow one side. So battery voltage do not pass to charger but charger voltage pass to battery.
Thanks bro
Can I use 1k resister?
Bhai 9w ya 7w led bulb use kare to us hisab se kitna resister and diode and battery chahiye..
Tried this and the hair fell off my dog, I can't feel my lips and the balance on my truck tires seems off. All I wanted was Chicken wings.
I am seeing you using 100 0hms resistance as well as the diode, why are you using them,and if the battery was a 12 volts what would be the value of the resistance as well as the value of the diode.please help ☺
100 ohms resistance was used to reduce current for charging led which needs 3 volts approx while the diode was used to protect return voltage to flow one way.
thank you again 😊
great thank you
If you choose 12v battery the resistor value should 680ohms...
And diode is for prohibit reversing voltage... You can choose 1N4007
without BMS this is fire hazard.
I think there is no problem because he uses a weak current transformer
Yes 😃
Where is the charge protection circuit....
cant it turn on the led while charg8ng?
BMS circuit?
Can i use 5 volts 1 ampere charger for this project ?
Please tell me where can i get LED plate
Charge karne diode kiyu Lagaya jata hai please explain
Diode se one side current flow hota hy aur reverse nahi jata. Charger remove karogy to battery ki power charger use karne lagega aur battery discharge ho jaegi. Islye diode use karte hen. Thanks for comments & watching. Plz subscribe.
I cannot find a led plate anywhere like this one is there a certain type of description for it?
This is 3 volts plate made in China & easily available in Pakistan very cheap around 15 cents each.
How can I find full charge
Don’t make this rechargeable light because here is no protection feature for the lithium battery.after some days the battery will be blast.you can use 4056 charging module for making this rechargeable light
that's really cool
kindly add online buying link of the materials used in this video.
Does LED warm up
Or does the heat damages the battery?
No it will not.
kya 1 battry ma 100 ohms legaga juldi reply do
from where I can buy that 100 ohm resistor and the 4.1 v diode ?
From any electronics parts shop or diode is available with any damaged CFL bulb. Thanks.
bhai iska backup kya rahega or kitne ghante charg karna hoga
do ghanty aram se khench leti hy.
Please share a link to find this led plate. It's hard to find a 3v led plate.
I purchased it from electronics parts local market for $0.15 per piece & its China made.
where do you get the battery
esta jenial ,un nuevo suscriptor
english please
कौन सी बैटरी है
great stuff, please what the name of the glue used
The glue I used is "GMSA" Extra Super Glue, Made in India. Thanks for comments.
tp4056 can work on two 18650 battery
Yes!
But TP4056 comes with dual charging too.
you can also use tp4056
How many watts?
It is fully safe or not.
I am still using since long time and have no problems.
Do you think its okay not to put resistor in the LED plate? Please answer. Thank you in advance.
I don't think its necessary because the battery will reduce voltage after few minutes if it is fully charged. Resister will lower its brightness. If you're thinking as a load resister, you can have it.
@@ScienceTechnologyExperiments I see. Can you please help me? I bought a small 30led solar motion sensor light (you can search it on google) and I replaced the pcb with TP4056. I'm worrying if I might damage the 18650 battery or the LEDs if I don't put any resistor in it. Do you have any thoughts in this? Please reply.
As specifications given by u r good but it should have been made on a small circuit board
Thanks for suggestion.
thanks for making this video
Thanks for watching dear
What stops it from overcharging? Do those batteries have the overcharge protection built in?
No protection circuit is added this time. 2 hours are enough for full charging. More time doesn't do any problem as I tried whole night. But don't charge more than 2 hours & check if its not heating up. You can use your own protection separately. Thanks
They probably have the protection circuit on the positive end cap if that's the case. Overcharging is not a maybe thing.
You are right, in very rare cells there are invisible protection circuit on the negative end which can be compared with an ordinary cell in length which exceeds few millimeters & that is removable..
@@ScienceTechnologyExperiments are those same as present on top of Li Po mobile battery ?
Great job.....
Thanks
Led heat ho rahi hai to kyaa kare
wo to hogi thordi. sab hoti hen. heat sink agar hy to laga len.
From where you got this led plate
any electronics market in your region.
I've been trying to order these types of LED which works with 5 volt but couldn't found them, only 12 volts and 24 volts are available, please tell me how can I order them
You can use 3 volts 1 watt leds 3 nos in parallel with star type heat sink either so total will be 3 volts 3 watts the same as I used.
Science & Technology Experiments Cool thank you
Science & Technology Experiments thank you
You did not use BMS.
Thank you❣️
can you give me part no of led strip
Where I can get 100 Ohm Resistor.
From any tv repairing shop or remove from any old circuit or might find in dead cfl circuit. color code will be BROWN/BLACK/BROWN. Thanks.
Where do you buy all of your individual components?
From electronic parts shop and cells from old laptop battery. Thanks.
Check AliExpress
Sir yde aap ek ek wayer btak banye to sir acha rahega
Bhai men likh likh kr batata hun q k language ka masla hota hy. meri vdos europe america men bhi dekhi jati hen islye.
vdo dekhne ka shukria.
sir charge kitne ghante ayega
Good night now it's time to go home
me gusto mucho
Thank you
Hi! Your video looks like it might be a big help for a project I'm working on, which is why I would appreciate it if you took the time to comment the approximate cost of making such a thing.
Thanks for comments. Batteries are used from an old laptop battery compartment which was free. In my country it cost me for $ 0.70
Science & Technology Experiments
Oh! Only $0.70?!
What about all the other stuff?!
Yes all stuff is for $ 0.70 except battery cells which were free from an old laptop battery.
Science & Technology Experiments
Okay! Thank you so much! It's going to be such a big help for my project! :-)
Welcome
great bro
Thanks
thanks for video but where are you from?
Karachi. Thanks
ty
very nice
Thanks
nice but looks like a bomb haha
how many hours to change
within 2 hrs.
Charging directly with 5v phone charger is really bad for batteries.
charging socket kase lagta ha
jese lagaya hy wese hi lagta hy. meri dusri battery wali video dekho us se mazeed help milegi. thanks.
please home made battery fan
How long will it take to charge for two hours?
Its takes almost 2 to 3 hours for fully charged.
Thank you
How long can I use it?
More than 2 hours.
Thank you for your reply
nice switch kase lagta ha
switch men 2 connections hote hen. ek direct battery se ata hy aur dusra led par lagta hy.
4volt 1200mh battery fan bana do please
Battery ke upar aik switch chupkao. Switch k upar ek chhoti dc motor chupkao blades k sath. Battery se ek wire positive se lekar switch pe lagao aur switch ka dusra connection motor pe lagao. aur motor ka dusra connection battery ke negative men lagao. Switch on karo Fan Chalooooo. Good Luck.
My charging led is always on,plz solve the problem
N.T I think you connect the diode in wrong position old change the terminal of the diode
battery price kitna he
200 ki lậptop ki battery mese nikly gy 6 cells
Sir THIS light i use a 5 volt mobile charger to charge this light sir this is wrong please reply
This is a 3 volts led light plate, you can run this with 5 volts mobile charger with resister after reducing its voltage.
nice
Thanks
how much its backup time ?
More than 2 hours.
there is ant chance to blast if i charge this bettery like you ..only use n4007 diod and mobile 5 volt charger ..
Sir after of full charge how much it support of time hours wise??
Please must reply me
Its good for 2 hours.
Science & Technology Experiments thanks
You mean it will easily pass our time for two hours
yes it can pass 2 hours load shedding time & I'm already using it. But be sure, the cells should be in good condition.
Science & Technology Experiments thanks for reply me and guide me.
One thing more, its mean we can't use old cells of laptop for better result?
I'm using old cells but those are in good condition. Test them with multi meter that should show 3.7 volts or little bit less.
Great people do so and think for pople
Thanks.
