Hi Julien,

thanks for the extended feedback!

Why there's the 45 kph class on vehicles while 
it's 50 kph on streets I will never understand. 
Some years ago it used to be 60 kph on this 
vehicle/license class. Some say the 45 kph 
nonsense is a result of lobby work of some 
international driving school conspiracy to sell 
more motorcycle licenses...

For the "low service battery" alert: you already 
have this, it's the 12V alert feature I 
implemented some releases ago. The alert just 
needs a reference voltage from the last charge 
cycle. If you did not receive that alert despite 
having charged at least once since mounting the 
OVMS, check your notification configuration.
