CFX v10 battery life indicator question

[ViperR]

Hello Erv and the TCSS family,
I need help with how to program my CFX v10 board with my 18650 battery to check power level via my noepixel blade. I know to use the AUX switch (out of deep sleep), but with a fully charged cell, the pixels only light up less than halfway up the blade and do not show anything when the cell is 50% or lower. And yes, my config file is set at the correct 122 pixels I have have on one side of my two strips (244 total). And I have seven cells that I rotate and they all do the same thing.
Is there a way to calibrate the board with a fully charged cell so the entire blade is lit and as the battery capacity diminishes less pixels are lit?
Thanks to all. I have three CFX's I want to do this with.
