T&T: Wiring start bank

[John Leroy]

Another wiring question;

It seems to me there are two theories about start banks;

1. Assuming a separate battery for the genset, you should reserve the  
start bank for the main engine starter only, so even if all other DC  
sources are exhausted, you can always start the engine.

2. House batteries are designed to use more of the available amp  
hours without damaging them, but light plates are damaged by high  
amperage loads. Start batteries have more robust plates and should be  
used for ALL high amperage loads, like engine start, AS WELL AS  
anchor winch and bow thruster.

Any comments?
