What I did on My Winter Break --- Electrical Updates

[SailingSeaDragon]

All,

Over the years I have upgraded the systems on board Sea Dragon increasing the need for power. Early on I increased the hose bank from one group 31 (105AH) to two (2) Group 31 batteries for a total house bank of 210 AH plus a starter battery, a group 24. Time has shown that this simply is not enough. At the same time I have worked trying to fit everything into the original 1981 Pearson DC panel

So it is time to bite the bullet and add more power and circuits.

The plan:
1. Rip out the current battery box & replace it with newer larger box
2. Expand the house bank from 2 each 12 volt Group 31 (210 AH) batteries with 4 each
    6 volt Golf Cart batteries at 215 AH for a total of 430 AH @ 12 volts. 
3. Replace the group 24 starter battery with a Group 31
4. Replace the 1 - 2 or Both battery switch with a Blue Sea Systems e-Series two (2)
    battery switch
5. Add a Blue Sea Automatic Charger Relay (SI-ACR) 12/24 volt 120A
6. Expand the original 12 DC circuits to 15
7. Add a 12 volt plugs at the Nav Station, Saloon, Cockpit, and V-Berth.
8. Install a battery monitoring system - Victron Energy BMV-702
9. Replace the 35 year old kind-a-smart 30 amp battery charger with a Sterling Charger
