I have copper connections, could also get marine grade copper connectors which are lined with tin I think. Only thing is, crimping the connection with a wrench seems kind of iffy, and doesn't give a me the "dimple" I see on the connectors someone else made for me. 

As far as the original battery box goes (which I've given up on), I supposed if someone really wanted to, couldn't they drop the bottom down lower in the original battery box? Though that would require removing the tank so a welder could do his work...
