You can also go to your local wholesale/retail welding equipment dealer and use industrial quality welding cable/terminals.

The dealer will have many gages (reels even) of black welding cable and a selection of terminals. Welding cable is very fine strands which are more flexible than standard automotive battery cable and the insulation is also very flexible and resistant to abrasion/chemicals. As well as a assortment of shrink fit.

Most suppliers will for a small $ amount crimp on the terminals and apply shrink fit etc.

Remember, measure TWICE and CUT ONCE!

Also if you have a scrap of steel approximately 1inch by 2 inch wide by 6 or 8 inches long available, drill a 3/4 to 1 inch diameter hole close to one end (must be large enough for the widest end of the terminal to pass thru) then drill and tap a 1/4 - 20 or a 5/16 - 18 hole 90* from the center line of the big hole. Clamp your tool in your shop vice, prepare one end of the welding cable/terminal place it thru the large hole, tighten the bolt and you have hand dimple clamped the terminal to the cable. (looks better than the “old” chisel/hammer method)

The large cables are for my Victron Inverter project

I'm in the "go to welding shop" camp. Had to create a "cable manifold" of sorts when I went with a pair of 6 volt golf cart batteries. Went with the biggest gauge they had. LOL, they charged me a 12 pack of beer.

About any size, any length, any termination.
