DIY Li-Ion Battery Capacity Tester V2.1 || Identify Fake Lithium Batteries at Home

18650batterytester #batterytester #arduinoproject
In this video, I will show you how I have made an Arduino-based capacity tester. This device can be used to check the true capacity of the fake Li-Ion, AA, and AAA rechargeable batteries.

Is it possible to check AH status of 48v battery after using it for 6 months? If there is a way to do this please reply and let me know. Thanks in advance...

Got the PCB from PCBWAY and built this. Thanks.

Congratulations 👏

What is maximum testing voltage?

[@udp47]

Useful project. But Link for Schematic and Code above is dead. Also the schematic in Instructructables is that of V2.0. Would like to see the schematic corresponding to the PCB. Thanks.

[@kosa2004]

Thank you very much for sharing with us. I am going to afterbuild it, since i have all the material needed. Fantastic job bro!!!! Keep up the excellent work! 🍻🍻

[@opengreenenergy]

Glad you love my work. Wish you good luck for your building 👍

I purchased a completed version of this. I tested a fully charged 18650 LiIon battery and it reported about 3,200mAh. I then put it in a charger and it immediately reported 80%, and when complete it had only put in 564mAh. I am fairly sure the battery is a fake, but your tester said it had a capacity of 3,200mAH. WHY? I will get a very expensive charger/capacity tester later this week and will see which device was correct, but at the moment, it looks like yours was incorrect.

[@danielkien7864]

Great job! So is the only difference between v2.0 and v2.1 the software? How do I order a complete kit for v2.1? And get the software too? Thank you sir.

When u were soldering the components on the pcb that was oddly satisfying😇😇

[@awnisharma]

Thanks for this great circuit. Just one query, iIs there any alternate of LM385BZ-1.2. As this is not available in market as well as online easily in India

[@opengreenenergy]

You can use this one. But you have to modify the code accordingly. www.electroncomponents.com/LM336Z-voltage-reference-diode-2.5v-shunt?gclid=CjwKCAjwq5-WBhB7EiwAl-HEkt_8NHR49PZ-FDmgE60ElwDdSml7umrCk0f6wrXVoz75KXHMfNNHrhoC4kQQAvD_BwE

So is the voltage reference connected to the analog pin A1 from the Arduino or not?

[@Vladimir-ju7gc]

doesn't work, no 1A consumption on the ammeter (24,30 mA), what's the problem? (V2.1)

Yeah it can be done.

Can this project be modified to test at least 8 batteries at once using arduino mega ? I cant find the code for the project plz help me
