[C320-list] Battery charging

[Dean Vermeire]

So, in the standard (default) configuration, it seems you would always 
want the battery selector on "Both" whenever running the engine or 
connected to shore power.  You may want to switch off to just one of the 
batteries when just running off of a house battery and want to reserve 
some juice to start the engine later.  But, you would want to switch to 
"Both" before starting the engine, so that you would charge both 
batteries after starting the engine without changing the selector while 
the engine is running.

Make sense?
