Connecting multiple power wires to battery post?

Does anyone know where I can find a battery terminal extension or some sort of “power strip”, whereby I can connect 5 power wires to a terminal. I can’t fit (5) 4 gauge power wires with ring terminals on my battery posts. They won’t fit. I searched around on the net but couldn’t find anything. I need something with a 1 or 2 gauge input and minimum of (5) 4 gauge outputs. Any suggestions?? Even a distribution block big enough would work, but can’t find one with that many outlets.
