Yes, there is an error in the schematic. I wrote it in the description of the italian version of the video, but not here. This is the corrected schematic: espelett.altervista.org/wp-content/uploads/2023/08/battery_tester-960x679.png Thank you very much.
Hi there, I checked the page in the description and cannot see the modification to allow this to work with 9V battery. Can you help?
hi is this applicable for 2pcs AA NI-MH battery? The discharge voltage limit can be set? and is there a tutorial on how to make it?
Thanks, but LM358 Pin 4 should be GND and 8 Vdd?
Yes, there is an error in the schematic. I wrote it in the description of the italian version of the video, but not here.

Thank you very much.
@@espelett Can I power it from. 18v and when use the same voltage driver lm358 and TIP120 npn and same resistor
Is it normal that during idle operation it shows 0.47v?
yes this is what it should show during idle operation. this is the voltage of the voltage divider. It is explained at 3.00 min.
Thank you for the tutorial. May i know how to modify for 9v batteries?
Hi. Check the page linked in description. I've added schematic and firmware for the 9V version.
@@espelett Saw it. Thank you
Can I use Arduino uno in this project?
Yes.
