Hey Mike I wouldn't worry too much about that copper bus bar connection. Figure damn near every copper battery cable connects to a lead battery post with a SS bolt, or to add to the metal soup a galvanized (zinc) steel bolt. What's a couple a more inches of copper if you spray it with a good anti-corrosive or even heat shrink the whole shebang with silicone inside to exclude moisture; unless there are service components that need to be monitored in the amp probe connections. Or if this will get too hot at some point. The better you exclude the salt water the longer any electrical connection will hold up.

> Last year when the display on my Zantrex XBM battery meter display died. I purchased a Paktrakr battery monitor with the optional current probe as a replacement. But, thanks to a tip from Mathew Geier here on the Electric Boats list I was able to get a replacement part and fix the XBM:

> I still hooked up the Paktrakr which works great for measuring the individual battery voltages but, I never did hook up the current probe.The Paktrakr current probe requires I use a copper bus bar attached to the most negative battery negative terminal. The Paktrakr current probe slips over this copper bus bar and measures the induced current. I have been debating about whether or not I should install the current probe for the following reasons:
