How to make 12v BIG BATTERY charger using computer SMPS. (14volt 10Amp output) 

Aap ne jo hola sahi hai normal load ke liye, Battery alag tarha ki load hai. Yeh khud ka voltage ko change karna nhi chahta h, chahe kuch bhi ho jaye. Isliye 11voltage ki battery ko 13 v me laga doge to wo high current khich ke supply ki voltage ko down karna chahega, khud ki Voltage same rakh ke....

Microcontroller er kono dorkar nei. Ekta op amp e enough

Yes I also have Hs8110 ic SMPS

I think same model something

15v tak. Kiunki iska output me capacitor 16volt ki hai, ush se jyada karne se blast hoga wo. Capacitor ko agar 25v ki replacement laga diya jaye, to 20v tak sayd ja shakte hai

@@FreeCircuitLab thanx for the information❤️

No Don't know

.75 ka double krke laga do

@@FreeCircuitLab 2.5 mm finolex laga diya

Yes but you need to use a low resistance 1 or 2 ohm to limit the current

Battery aysa load nhi hai. Battery non ohomic load hai. Yeh chahta hai iska voltage fixed rahe chahe kitna bhi current flow ho jaye

Agar aesa hota toh charging ke time battery current dheere dheere kam kyu hota Aur battery ka bi apna internal resistance hota h

Nhi short protection pin se kaam nhi hoga, because ush error signal supply shut down ho jata hai. To hume ek aur Op Amp ic use karna padega jisme current comparator circuit rahega aur overcurrent hone se voltage down karega.

-12 line feedback control offer nhi krta hai, usme 2Amp tak load lega....

@@FreeCircuitLab thanks brother , but I am using it for charging 12V 3S 42 Ah lithium ion battery pack. Kindly suggest me as I have 12-0-12 transformer also which I should use .

Bana lo, bahot simple... Wo sab protection pin me 3.3v de dena standby 5v se koi voltage divider bana ke. To protection disable rahega, aur aap feedback pin se +12v line ke bich ek variable resistance laga dena. To 2.5v to 12v adjustable ban jayega... (Aur wo Variable resistance ka connection achhi tarike se katna ta ki kabhi disconnect na ho jaye, agar ho jata hai to feedback open ho jayega aur supply ki output voltage bahot jyada bad jayegi, output capacitor blast hogi aur dusra kich components bhi damage ho jayega.

@@FreeCircuitLabmene bi socha tha per ye bhut risky ho sakta h kyuki voltage jese badegii output ampere reduce ho jayegii Aur sare capacitors bi change karne padenge jinki low voltage value h aur diode bi high voltage wale lagane honge

If your circuit is short then the input power will be converted to heat and it will burn your circut but i a series lamp is connected the power will be converted to heat and light 💡 from a bulb with no lose

Abhi to plan nhi hai, baad me karenge

Yes

This is normal, you can't load a single line. You have to load 5v, 3.3v lines also. Still you can fix it by disconnecting the feedback Resistors coming from 5v or 3.3v (there are 3 Resistors coming from three lines). This modification might increase the 12v rail a bit, you can counterfeit it by connecting a suitable Resistance parallel to the 12v fb Resistance which you didn't disconnect.

Resistance lagiye dao 1Ω

Hobe. Current limiting dorkar

Disconnect nhi hoga. Just current very low ho jayega

Red probe connect nhi kiya tha. Amp ke liye alag probes nikla hua hai meter ke andar se do black taar 1.5sqmm copper

@@FreeCircuitLab hanji sir

It depends. 5-6 hours

Ic te ekta extra protection ache (short protection) otar voltage ta probably max limit exceed kore jachhe, sudhu 12v line er feedback ta thakbe baki voltage gulo feedback Resistance khule dao

@@FreeCircuitLab ধন্যবাদ! দাদা, PT তে দেখলাম ভোল্টেজ একই থাকে। ১৪ভোল্টের নিচে আমি যদি ডিরেক্ট ডায়োড থেকে লাইন নিই, তাহলে অফ হয় না। কিন্তু আউটপুট থেকে বাল্ব জ্বালালে অফ হয়ে যায়। বাল্ব ২.৮ এ্যাম্পিয়ার লোড নেয়। আর ১৪ভোল্ট আপ হলে ডায়োড থেকেও যদি লাইন নিই, তাহলেও অফ হয়ে যায়।

Transformer designed for 12volt above

@@Devendr099 Sorry your understanding is wrong. the concern is SMPS not Transformer. Here circuit will be designed as per requirement and if we hack, it may impact on circuit and may cause damage as well.

Theoretically yes but it doesn't make sense.

SMPS fail ho shakta hai.

@@FreeCircuitLab load resistor to lagayi hai output me ji

Ground ke sath resistance kam karenge to us pin me sahi voltage rakhne ke liye supply voltage badhana padega kiunki ab ground ke taraf load badh gya. Isliye voltage badh raha hai, ultimately us feedback pin ka voltage ko same rakhne ke liye

Yes

Thank you brother!!

Variable power supply making wali video dekho. Usme bataya

You have misconceptions

It is very simple, I might try later
