This has been changed in the latest firmware. A good change! The battery indicator refers now to the configured discharge limit. So if that is set to 50% everything is correct! The "correct" value is shown at the percentage SOC screen.

I believe discharge limit is the alarm setting (#33), so if you set 50% and only 100 of 200 Ah, then the battery symbol showing empty (no bars) but SOC 50%. In the case below, alarm is set at 20% because Lithium. Unit shipped from Victron in Feb 2019 and latest firmware. It seems more of a problem for the new firmware..?

I think it's the 'SOC relay' setting. (please correct me if wrong, don't have the device at hand)
