Battery area 50A SAE type B?
Next to battery is a small black device with green letters
Model 25450 with 32V/50A?
What is it?
Does it fail since exposed under coach?

That's your 12v DC circuit breaker, being exposed will not hurt it 
However if it fulfills its reason for being you will lose 12v and should expect a fairly major problem 
It is resetable, a red or yellow "flag" will jump out, simply push it back in.
Just beaware a VERY large, damage causing amp draw has been detected

Sure looks like 32V150A to me.
My 2021 Axis 24.1 has two breakers in the battery compartment: one 50A for the cable to the converter and one 100A for the generator starter cable I think. There is a third cable, but it is not circuit breaker protected and I think it goes to the BIM.
Strange that one year later there is much difference in how the DC system is protected.
If Scubawise's breaker really is a 150A as I suspect then a single breaker to protect all circuits works as long as the wire is #2. But on mine the wire to the converter is smaller, maybe #6 which is too small for a 150 A breaker.
Oh well, Thor knows best, right!!!

It's 50 amp, not 150 amp.

Agreed. Then it is probably protecting the cable to the converter.
