   Correct.  Wired in series (positive to negative) the AH remains the same   
   and voltage doubles.  Wired in Parallel (positive to positive) AH   
   doubles and the voltage remains the same.

   You definitely will have to reset the AH capacity.  Other than that, it   
   looks like everything else is automatic.  Here's the manual in case you   
   don't have it.
