I've a NASA BM1 battery monitor - I'm unsure what this display is, Does anyone know what this means ?

Showing the Voltage and Current Press V&A key to show the present battery voltage and the present battery current, as well as the estimate of the state of the battery's charge on the scale. The maximum current measurement is 102 Amps. A second press on V&A will display the starter battery voltage together with the symbol ‘St’

Ahh, thanks Stanbrook !
It’s not connected to the starter battery so zero V makes sense
