Buddy cold also try the Installgear also . you just cut the end off a store bought cable and strip back and plug in then tighten the Allen bolt . I have started buying my fuse blocks in this style ,saves some work . I think I will melt some solder on the end before I tighten it in thoughIt sounds like you are looking for something like a "mil spec" battery terminal available on Amazon. Allowing you to bolt multiple wires to the same battery post. I've used the Audew and CrimpSupply brands, prefer the latter but they are mostly the same. I've also bought them in better quality from electrical retailers specializing in marine and heavy equipment. You'll need terminals, wrap and crimper for the wire gauge you are working with. TemCo is a great place to purchase this stuff, they have an Amazon storefront. Their copper wire and tinned terminals are American made for the most part and more reasonable than the Chinese sheeite everybody else sells.
