<DIV><FONT size=2 face=Calibri>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. </FONT></DIV>
<DIV><FONT size=2 face=Calibri></FONT> </DIV>
<DIV><FONT size=2 face=Calibri>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".</FONT></DIV>

had a Trojan battery rep. state that they did not like to see more than [12]
