BMV and starter motor Installation guidlines

Hi

I can't find any exampl wiring for a system where the 'service' batteries may get called on to run the sterter motor in the event of the starter battery going flat.

I am re-wiring my boat and have an old BMV and a large starter battery and bank of 4 service batteries. I have a change over switch to allow me to power the starter motor either from the starter battery, or, in the event of a flat battery from, the service battery bank. Will the Smart Shunt handle starter motor currents? This is a 5l diesel engine, so quite large starter currents, I don't have any figures for the starter current draw.

Any suggestions welcome.

regards, Granby
