Two reasons: First, I'm interested in electrical systems, so I was
curious to be able to measure the voltages during operation.  I can
probe the external regulator's connectors.  The internal regulator is
a bit opaque.

Second, I've been thinking about building my own smart regulator with
a microcontroller, to start out at a higher voltage and then drop
down to a float voltage after some time, or even sense the charge
current into the batteries, like my Promariner does.  The brush
assembly for Dave's external regulator supports that kind of experimentation.
