Perhaps off topic, it's been said here previously by others, but is worth
repeating, good old Vaseline, coating all exposed metal surfaces at battery
terminals, totally eliminates the corrosion issue. It's benign, inexpensive and
available everywhere.

Yes, especially with flooded batteries where the posts are much more subject to
corrosion. I am getting too old and decrepit to get out in the field much
anymore, but in the past I have seen complete strings basically isolated by bad
cross connections, usually (but not always) due to corrosion at the terminals.
In extreme instances I have seen cross connect cables totally gone at the
cable/lug connection point - nothing but green powder. 

With multiple batteries and banks, correct cabling and connections become much
more important, because they may not show up until too late. With a single
series string it is usually obvious if something goes bad, but with multiples
not so much. Sometimes you have no choice but to use large strings, but I have
seen installations where 60+ 42 amp-hour batteries were strung together, because
they were "cheap".
