LOL, are you suggesting that? Consider that stranded wire has a very large 'surface area'. 6mm bullet connectors are not rated for 160A use. If you are that concerned, just solder the wires together, you don't need connectors. You know, 8mm is only about the size of a pencil eraser. Is that too big? I think not. But of course, you can do whatever you want (silver solder, 10AWG wire, etc) if it makes you feel more comfortable. I'm just not sure if you are looking for advise, or just want to stir up some excrement. BTW, you're welcome.
