Managed to get everything up and running with your advice - One thing I needed to do first was flash V1.0.0 as the system was running V1.0.0beta and had an older version of ESC tools V1.08.
Once V1.0.0 was flashed the ESC tools was update to 1.20 and allowed me to update to the ESC firmware version 38.
After everything flashed and updated I now have the battery information in QGroundControl!
Many thanks again for your assistance! 🙂
