New 4D Batteries and Refurbished Heart 30 Inverter Charger installed

The title says it all.  I was going to hold off on installing new Batteries until I needed them, but i found a great price $350 each for two 4D AGMs of 200 A-H each.  And since I decided to put this inverter charger back in, it seemed like a good idea.    Still to do, hooking up my second shore power connection which will serve my start battery charger, and future shore powered air conditioning.  I also plan to add two 30 amp breakers just after the shore power connection to make servicing the AC Panel more secure.  I also want to bond the two AC panel grounds together.
