Battery charge Kaise hogi , diode ko palti Karo Bhai, tabhi battery charge hogi.

[@rosekreuze]

i have a 12v TV in the dining room which consumes atleast 1.5amps, my question is, during an event of power failure, how do you deal with reverse discharge phenomenal? pretty sure you charger is also pulling currents from the battery during brownouts. im asking coz thats exactly happening to my setup. my tv could run for 2hr straight on a 3s 3p setup. but other than the tv, the charger also discharging the battery. i also tried using diodes on the charger side but im also experiencing a huge voltage drop of 0.5v. the bms requires atleast constant 12.6v to reach float voltage, but with diode voltage from charger plays around 11.9v to 12v thanks in advance

[@abubakarsiddik88]

Vai 5 v/3.7v theke eta kojabe

[@adredy]

And what ? this is automatic ? haha

[@Mukul_Adhikary]

N.B: this circuit will not charge your battery. Battery needs to charge another way. Or just reverse the Diode. It will charge & auto on/off your bulb.

[@yigitbekirtemur4178]

Can you share this schematic diagram

[@sachinsharan1]

Is This charger will also charge that battery at same time,?

[@TechIdeasAG]

Yes, ofcourse

[@sudippramanik1307]

Please use related circuit diagram with your model.

[@pavelcimbal9362]

lamer. the diode on the video should be put in reverse! to protect reverse polarised b-e and to do the actual recharging.

[@stefanmoser4348]

ahoj Pavle! I have not tryed it yet, but your proposal makes sense 👍 😃

[@stefanmoser4348]

now I've tested the circuit. with the cathode of the diode connected to the base of the transitor the circuit works like it was described. diky moc! 😄

como crear un modulo de luz de emergencia para entrada de 12 voltios y salida 12 voltios

[@Nagraj22589]

Hi bro its working very well. But small issue voltage dropping 12v to 9v how solve this problem

[@sak4766]

Kya ye circuit 4v battery, 4v power supply, 4v LED kam karega

[@ashrafashik7871]

How it works please explain me

[@vishaldevganLove]

Ye sahi se kaam nhi kr rha h bhai puri tarah light off nhi ho rha h

[@athurein26]

Hi, I set the same as you showed in video. But, light was not off when the adapter connected to power and just a little dropped brightness. What can the reason be?

[@beboo1414141414]

Did you know what is the problem because i have the same problem

[@athurein26]

@@beboo1414141414 I think that the transformer voltage is 12 Volts. So that, the Charging voltage must be 14 or 15 Volts.

[@athurein26]

@@beboo1414141414 can you tell me please?

[@athurein26]

@@beboo1414141414 I think there is one more diode need.

Clean and clear demonstration. God bless you. Thanks for your guide for every one.....

[@anupjana3859]

i can use the mobile bettery.but betery is short and bust prosibl. please said me.

[@electronic7979]

Good idea 👍

Please make video on spy camera In easy step. i 'm wait for next video

[@rociocausing6999]

Thank you, this is very usefull to our place always have power failure.

[@AntonioCarlos-ru3we]

No tempo 2:45, a luz apaga antes de apertar o botão, depois há um corte de vídeo de alguns segundos ou é impressão minha?

[@unknowndj242]

What could be the purpose of this then Sir?

[@farhanhony6504]

Battery charging not working, it's wrong

[@Mohammedazeezbgw]

I did as you but When I turn on the power the battery is not charging and the light is less bright when I turn the power off, can you explain please?

[@athurein26]

Same to me what you have mentioned.

[@pollypizy.danceclass7567]

Can i have a circuit diagram

[@ymayarmardan8858]

D 331 kase used hoga

[@gilmarmartins3683]

Muito bom, executei o circuito e funcionou muito bem, mas alguém poderia me informar como posso utilizar esse circuito e manter a bateria carregada quando não está no modo emergência?

[@alokbudakoti71]

इस में ऐसा प्रयोग हो सकता है कि बैटरी से चले और रात को ही सुबह होते ही अपने आप बंद हो जाये

[@dilankadilshan4677]

this circut sport to 4 volt bettry

[@mgrdigimarketing3035]

Can you please put link to parts used?

[@RKPEditor9613]

Battery charger hoorah

[@muhammadazam7077]

Thanks for video Please show the diagram also

[@BobDiaz123]

I wish you had a schematic with a parts list. It's very hard to see how your circuit works.

[@dvsmotions]

there's 4 parts. And they are laid out extremely easy to see. Is it really that hard?

[@krosavcheg25]

Что это за хренотень? Есть кто пояснения к видео может дать?

[@АлександрБогатько-и7е]

Из того что я смог понять, это лед светит от аккума, когда включена зарядка он гаснет, может для аварийного освещения, .... Как- то все сложно)))

[@athurein26]

I used with 12 Volts battery with 12 volts charger . It’s not switched off, but a little drop down the brightness when charger on. I think the charging voltage should be more than battery’s voltage.

[@GERARDOIC]

Cool

[@arif24arif42]

plz 50w led power suplay for transistor, how work VDO show

[@Perepodvyvert_s_perevorotom]

One relay with 220V coil replace schema. :)

[@shivalahori3943]

Bettery over charge problem nhi hoga kya isme?

[@RKPEditor9613]

Please comment

[@ashrafmk1822]

I did this ckt but not work

[@anthonykeepcalmandsoymusic7095]

Se puede usar el mismo circuito para 5v? Oh hay que cambiar algo más? Can the same circuit be used for 5v? Oh you have to change something else?

[@TechIdeasAG]

Then use 470ohm resistor

[@binarix128]

Great, very useful! 😀

[@warisahmed3216]

Ak bat samaz Mai nahi ki direct battery se switch on off kyo nahi laga sakte

[@AzharAli97_]

Waris Ahmed lag skta hai ap charger ka position point direct battery pr lga dain or battery sy jo positive wire led pr a rhi hai usme switch lga dain

[@anismuha]

Friend, the diode in your cìrcuit wrong direction. After i reverse it the cathode put in the base and the anode put in the emitter, it works finally. So please confirm if this is correct. Thanks

Is this circuit can be used by li-ion or li-polimmer baterry of 3.7v on 1w to 50w led light circuit even ac DC circuit ? Any risk or burn ?????

I like your videos. They aren't like the other videos about electronics from non-english countries who show pointless things. Despite you obviously not knowing English well and not using any perf board, I still like what you do.

[@diyandassembling2907]

Useful. Can the same circuit be used to turn on ac lights with 220 volts. Instead of 12 volt battery.

[@umarirfanmughal4758]

Automatic battery charging or not

[@alphinthomas5422]

Great work

[@mattikaki]

Huh. You have very, VERY dangerous electric systems. Are you located in India or somewhere? These kind of systems are prohibited in EU and I don’t recommend they anywhere. But the automatic switch looks fine. I didn’t see any schematic. Could you add it.

[@Fotovliegtuig]

Can you explain why it is very very dangerous?

[@didiersee]

Very well from Belgium 👏 👌 and you can perfect the system with a programmable clock on charger then it is to discharge the battery occasionally. In French below. Très bien et pour perfectionner le système on place une horloge programmable sur le chargeur pour décharger de temps en temps la batterie.

How many Apms maximiun supports this circuit ???

very useful specialy in my country where power outages are quite very often 😩

Que otro transistor puede servir? Y dice luz automática pensé que cuando cortas la energía se enciende con la batería como una luz de emergencia. No entendi

[@alexissantos1838]

Muy buena excelente y una pregunta y como aria para regular el voltaje de la bacteria sino se puede sobrecargarse si no pongo un automático a la bacteria así corté cuando tenga carga máxima saludos desde Argentina

[@hacker6695]

Why used D882? Can we use TIP122?

[@TechIdeasAG]

Yes, ofcourse

[@gtek34]

Does it have the ability to charge the battery?

[@mrelectronicslab799]

5v pe kam karega ye surcuit

[@kornpb]

Does it also recharge the battery? But it seems to me that I would not cut the power when the battery is charged! that's right?

[@TechIdeasAG]

Yes, bro right

[@natureworld295]

So how is that automatic ? You wasted my bundles

[@kapilsood5523]

Really great 👍

In commercio si trova difficilmente un dispositivo con queste caratteristiche, io ne cercavo uno simile per una luce in casa... grazie mille! Thank you so much!

[@vb2912]

D 882 or some other transistor can act as a switch and instead 12 v charger we can use lm 317 for charge and regulate the current on full charge of 12 v battery.

[@SanjayFulsunder]

Do you mean the LM317 will simultaneously charge the battery? If so please post the circuit diagram.

[@duniabiru9432]

i love this project, verry usefull

[@anismuha]

Friend please let me know is it an npn or a pnp transistor for D882?

[@TechIdeasAG]

Bro, it's NPN
