M300 second battery serial number is empty

[KG3RK3N]

Currently, the library returns 2 batteries but only one has a serial number on a M300. Latest firmware & FlightRecordParsingLib version was used. We changed the batteries 3 times (6 batteries in summary) and each time only one serial number was returned, the other one was always empty.

Here a sample:
