Voltage measurement calibration?

Is there a way to calibrate the measured voltage of the Vesc? I´m having a slight difference between my own control screen and voltage seen by the Vesc tool (Dmm says 41.03v and Vesc tool says 40.30v) makes the Battery % monitor on the mobile app show 85% on a full battery..

Finally got my 5-month project finished, trying to make some finishing touches and that is bugging me..

The measurement will be in line with the precision of the components measuring the voltage. Typically these components have a 1% tolerance on original hardware. For third party that might be more.

SInce there is more than one component involved, tolerances can add up or cancel each other out. So there is a range of possible deviations.
