I put a circuit breaker, instead of a battery switch on my starter circuit. http://www.bluesea.com/products/7089/285-Series_Circuit_Breaker_-_Panel_Mount_150A

Just an FYI on breakers for battery OCP..

Fuses or breakers for bank installation should have a fuse or breaker with the proper AIC rating for the bank. AIC is amperage interrupt current. Any bank which has more than 1100CCA would require a fuse or breaker with a minimum of 5000A AIC. Most 4D batteries exceed 1100CCA as would just about any paralleled bank...

Class T = 20,000 AIC
MRBF = 10,000 AIC
ANL = 6000 AIC (@32V, closer to 10,000 AIC at 14V)

That's good to know, I had the breaker on a group 24 battery, separate from the four 6V deep cycle house bank.

A 3000A AIC rating is fine for a single G24...
