I have a Mobius V 2000.
Indmar Assault 5.7L.

About to install a second battery, deep cycle, but need to know the Amperage of my alternator......

Can't read anything on it, as it's probably the original....

50amp standard?

How can i make sure?

Should i play safe and go with an upgrade?

Going to be running an amp and lights from the second battery.
