Had that super cold snap here in Montana.
My touch screen only shows Dashes (--)
I charged the batteries after warming up the battery compartment last night.
Charged all night long and nothing shows on battery level. only dashes.

No battery level shown on the Cerbo touch screen only shows Dashes.
11.3.8 in Lynx shunt manual may address this.
11.3.8. State of charge is missing
This means that the battery monitor is in an unsynchronised state. This can occur when the battery monitor has just been installed or after it has been unpowered for some time and is being powered up again. To fix this, fully charge the battery. Once the battery is close to a full charge, the battery monitor should synchronise automatically. If that doesn't work, review the synchronisation settings.
