[C320-list] Battery plan

[Warren Updike]

Ted, I have an article and pics of our upgrade. Let me know and I can send them. I'll be on a cruise for a week so will respond after that. 

Who will attach connectors to battery cables? Not a trivial exercise. Ultimately, several of us chipped-in to buy a hydraulic crimper. However, I bought made-up cables from http://www.genuinedealz.com/ that were reasonably priced and well done. This is a very important part of the process. Poorly attached connectors will cause voltage drop.

As for rest of cabling plan, perhaps a wiring diagram would be easier to examine. As it is, I'm off on a week-long cruise; but, will keep an eye on this list. 

FYI, some people choose to use the house bank for starting and hold the start bank in reserve for emergencies.

Also, in using a dual-circuit switch as I and others have done, there is one consideration should the need arise to use the "Combine" option. Do not combine banks unless first disconnecting the positive cable from the failed bank. Otherwise, the failed bank may suck charge from the healthy bank. One advantage of the 1,2,Off,Both switch is you can easily choose which bank to start with.

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.
