BMV and CCGX are not matching

Have a 48 volt system using lithium powerplus batteries on a quattro inverter. BMV will read 54.2 volts and CCGX will show 55 percent, wondering why they are not matching up.

cheers

For comparison, how many Volts is the CCGX showing and what percent is the BMV showing?

Which device is set up as the system battery monitor?
Look in Settings -> System setup -> Battery Monitor

@Nathan9393 If it is using the BMV as @WKirby suggested to check; and the BMV itself is not showing 100%; then it is possible that is has drifted in its SOC detection.
