Got to practice with a new tool today. A colleague developed and manufactured a unique battery terminal crimping tool made especially for the heavy gauge battery cables. This is an interesting tool as it claims to actually shrink the terminal around the cable. He doesn't produce this tool any longer but had some extra components that he keeps on hand for any warranty issues. He put together a kit for me as we had the same interests in aircraft building. So, today was practice. I used some 2 gauge welding cable and terminals I purchased at the local welding supply store. It's required to be mounted in a vice, which is the only drawback. The cables need to be planned well in advance. The tool is very well constructed and seems to make excellent crimps / swage. I obtained a "fake" empty “E” case for fitment of the battery from EarthX which is the same case as the ETX900-VNT that I am planning on using.
