There is no such thing like the wire too thick for application.
Even when #2 wire might not be needed by electrical codes, those codes allow for wires warming up and that means resistance.

IMHO the galvanized nuts are used so the manufacturer will sell more batteries when old one will corrode the terminals out
And don't clamp copper connectors to aluminium or galvanized bars.
Those connections will make electrocorossion and will fail in a year or 2.
