Update the battery system

[How Korsu]

I have found that we tend to drain our batteries on a two week or more cruise. I have carried a third "emergency" start-up reserve in the past. Now I would like to add another bank of one or two batteries to use as the start. I have a permanent charger now wired in and it has the capacity to add another bank. I don't have refrigeration but I am thinking about adding it.Any advice would be appreciated.

BATTERY UPGRADE

I JUST UPGRADED MY BATTERY SYSTEM. NOW I HAVE 4 GOLF CART BATTERIES,(420 AMP HRS) UNDER THE SEAT FORWARD OF THE NAV STATION. THESE ARE WIRED TO THE # 1 POSITION ON THE SWITCH. THIS IS THE HOUSE BANK.I ALSO HAVE A GP 27 IN A BOX BEHIND THE ENGINE AND NEXT TO THE CENTER WATER TANK. THIS IS WIRED TO THE POSITION # 2 AND WILL BE USED FOR STARTING ONLY.HOPE THIS HELPS. I KNOW THAT I HAVE TO PUT A COMBINER/ISOLATOR SOMEWHERE IN THE SYSTEM BUT HAVENT FIGURED OUT WHERE YET.
