1. Li-ion Battery Capacity Tester Circuit
2. Lithium Battery Tester Circuit
Hello, Friends in This Video I will show you how you can make a battery capacity Tester or constant current load circuit with the help of this circuit you can check any battery like 3.7V, 4V, 6V, 9V or 12V. We will compare our circuit with the Chinese battery tester module. I made this on a homemade PCB. Circuit Diagram and PCB Layout below:-

Ye to bhut jaruri video thi kmal kr diya sir g bhut bhut badiya and asan circuit and aapke samjane ka tarika gajab h sir

[@SAI_LINGESH]

Instead of that two "5w 7k5 ohm load resistor" can I use alternative loads? Like bulb/motor/anything else which drinks so much energy as load?

[@SharvilSawargaonkar]

If you are speaking of the circuit no, it's not a load resistor it's a shunt

[@Rajjzvlogs]

Bhai kya hum isme 500k preset ki jagah 100k aur 1ohm 5watt ki jagah 0.5ohm 5wtt me use kar sakte hai?🤔

[@FreeCircuitLab]

Bhai thoda upgrade karna hoga. Automatic off at low threshold, automatic stop the watch. Yeh do feature lagaoge to aapko bar bar voltage check karna nhi padega. Aur meter bhi nhi Chahiye

[@startechnical351]

Right

[@viktorkadet697]

yes wooow absolutely excelent description for me which is new to this eletronic stuff your site is rly good nice

[@Nochannel-gw6wd]

Main apne diagram ke hisab se circuit banaya. Par uska current discharge rate automatically change ho raha hain. Kya karu. Please bataiye.

[@nandeepkhajuria2326]

Please reply what is the maximum Current this circuit can handle because I want to check 12v 40AH battery so the discharge current will be 5a

[@javed5414]

Veri nice

[@svem1972]

Sir excellent demonstration...also I would request you to do one BMS with deep discharge protection. I know you have made BMS circuit with over charge protection but not deep discharge. If you can make both over charge and deep discharge nprotection would be helpful to all of us...

[@svem1972]

@@Ethcircuits please sir eagerly waiting so that no need to buy BMS for 12v 3S

[@parthsharma1571]

Wonderful

[@startcherif]

very nice video

[@fleshharmony9237]

Excellent job, I really appreciate what you are doing.
I want to ask, can u add a kind of timer circuit that monitor the start and discharge stop time also maybe multiply the discharge current and the stop hr.
Hope to hear from you.

[@Ethcircuits]

Thanks for suggestion bro I will try to make a video on this

[@mohammedmobarak8719]

Nice vidio

[@dalip1404]

👍👍👍👍

[@rajeevbag4552]

Sir, 500k trimpot ki jagah koi dusre value ka trimpot use kr sakte h kya....
If yes then uski range bata dijiye

[@rajeevbag4552]

Sir, reply 🙏

[@startechnical351]

Han use kar sakte hain

[@MuhammadDanish-xz3qt]

Sir hum lm358 ic ki jaga 555 timer ic use kar saktay hain kia.

[@billyjoegilmour95]

I would think that you can use because they both has the same pins

[@owndream9697]

sir if we want to discharge 12v battery at 2-3Amp can we use same circuit

[@keith_ferdinanduz]

Yes, but you'll need a high power mosfet with a bigger heatsink.

[@ImranKhan-hv7dd]

Sir 12 volt ke battery check karny k leay lm7805 ic volt amps meter k leay use karengay ya board ko power deny k leay...?
12v ke battery k leay power source bhi barhana paryga Kiya ya 5v he rahyga. Board or meter ko to 5v supply de ap ne lm7805 ka use kiyon. Mari es confusions ko right Karen plz.
Ap ke video kafi martaba dakhi meny par ap ne thek se samjhaya nahe ya mujhy samjh me nahe areha.

[@Ethcircuits]

circuit ko input 5 volt alag se de aap meri website pe jake circuit ko dhyan se dekhe input alag se 5 volt diya hua hai

[@birendrakumar-gl5gq]

Please make internal resistance tester for Lifepo4 and Li-ion Cells

[@Ethcircuits]

ok, Thanks for suggestion bro

[@ashutoshmishra1130]

What is the maximum discharge current we can set using the potentiometer?
