Hallo all,
please check again photo with SMD resistor again - it's NOT "010" !!! its "01D" - 1% resistor with value of 100kOhm (please refer to http://www.rom.by/files/SMD-Resistors-EIA-Markings.html). Some high (mostly 1206 size SMD) precise resistors are marked with 4 digits, but smaller 0805 and 0603 resistors have mixed coding with digits and letters. It is already 100kOhm on PCB. For that modification please ONLY cut trace between 220kOhm resistor and A0 pin , scrape some lack from track on both sides cut place and solder small resistor 100kOhm on that place or put small axial wired resistor between pad of 220kOhm and A0 pin.
Sorry I don't have that board and can't make photos.
B.R.

If some got the code. Please share it! Here I am not able to understand how can I calculate the value of it, its really hard to get.
Thank you!
Thank you!

So do we need to solder a wire from the + terminal too the AD pin?
I also want to monitor the battery voltage.
