[C320-list] Battery plan

[sail-ability sail-ability]

   Hey Ted; I did something very similar on my boat a couple of years ago.
   All I did was connect the two 4Ds in parallel like You're suggesting
   and left them connected to #1 on the main bty switch. I bought a 27
   starter bty and installed it fwd under the stbd settee. I connected it
   to the #2 cables on the main bty switch and also to the windlass
   cables. the only extra cabling I needed to get was to connect the two
   4Ds in parallel. Position #1 on the bty switch is for powering the
   house draws. Position #2 on the bty switch is for the starter and the
   windlass. This will save U a lot of work and extra cabling.

   Cheers

     Can you tell me if I am missing anything in the below plan. This is
     phase one.
     - purchase 2 4D SRM Interstate batteries. They will remain in
     current location.
     - Build a shelf forward of the 4ds and place a group 27 battery in
     this location. Currently have a Group 27 purchased last year.
     - purchased two battery cables 6 feet length, connect 4d's together
     positive to positive. Negative to negative.
     - purchase 21 feet battery cable and run from starter (negative) to
     group 27 negative.
     - purchase 6 feet battery cable, negative to negative, and connect
     house batteries
     - purchase 20 feet positive and run from group 27 to position 1 on
     the battery switch.
     - positive on house bank to position 2 on battery switch
     - positive from engine on both position on battery switch.
     Charging: both house batteries run to a ProNauutic 12- 30 P charger.
     - Purchased a Xantrex digital echo charge to connect group 27 to
     house batteries to keep the starting battery topped up.
     - battery cable 1 / 0 battery cable
     Your evaluation / comments would be appreciated.
