[C320-list] Starting Battery

[Robert Seastream]

Get the largest start batt that fits.  I've got a group 24 AGM as a  
reserve start battery, wired to position 1 on the main batt switch.   
It does the job when needed.  The original two house batts are  
paralleled on position 2.  The upgraded high output (125 amp with 3  
stage regulator) alternator is directly wired (via a 150 amp fuse) to  
the paralleled batts.  An 'echo' charger passes charging energy  
through to the start batt as needed.
