[C320-list] Battery plan

[Utility Email]

Ted,

I did the same thing that John did.  Photos of my installation are on the C320IA website under owners photos.  I also used a Xantrex Echo charger to charge the G27 battery from the large house bank.  

More recently, I upgraded my original 4Ds with 6V GC batteries and upgraded my original Charles 30A charger to a Sterling 40A charger, and added a flexible solar panel that I can deploy on my bimini.  Photos of that installation are also in the Owners Photos section of our association website.  Great setup.
