Default Crimp, solder, both?

Just assembling my 12V battery cables for the camper.

External diameter of copper cable inner is around 5mm. Internal diameter
of connector (ring terminal) is nearly 8mm. So not a tight fit.

I was intending to crimp - not sure now if I should cut a slot in the
tube to allow the connector to crimp down further or just flatten it out
to get a grip.
Looks as though it has been folded then welded/brazed shut so I would be
undoing this last bit.
As it isn't as snug as I was expecting I am now wondering if I should
run some solder in as well.
Just solder doesn't look as though it would give a secure enough joint -
and I've never soldered multi-strand wire this thick before.

Got the wrong size crimps then? That sounds like 16mm2 cable to me, with
(probably) a 25mm2 lug. Filling them with solder is never really
satisfactory in the long term. It may be worth finding someone who will
donate a couple of smaller crimps & fit them with a proper crimping tool.



The link shows a 20mm^2 cable - so I assume it is this.
The other link offers connectors up to 16mm^2 and up to 25mm^2.
So for 20mm^2 I have to go for the 'up to 25mm^2'.
