So, you are soldering the braid together to make it possible to secure it on the terminal?@Bob B @ghostwriter66 I won't have time this weekend as I planned, but I made a quick concept version - see pictures below. This is done with the wrong vice and at the end of the braid which I usually discard since it tends to be all 'fluffy' - it's also not fully inserted. I also didn't drill the hole. The annealed copper tube was 18mm outer, 16mm inner diameter and the braid is ~25mm wide. One can tin the end part with a torch if needed/desired without solder wicking all the way on the braid (it's a pretty controlled process, you can also feed solder through the drilled hole, etc.).
One nice thing about using tube like this is that you can create single strands with multiple contacts, so if you for example want to have one with three holes (two ends and middle), this is easy as well.

If needed, you can also grind the ends a little should they not be fully flat. However in the pictures above that's just because of the wrong vice.
Adding lead, tin, and copper to aluminum battery terminals is inviting galvanic corrosion.
The hidden nooks and crannies of the braid could trap moisture and prevent discovery of degradation at the early stages.
