If its the one with the rings the only difference is that those need to use a crimp ring to connect. the one I am selling allows you to plug it directly into the cap.
Also as the cap has 4 connections in the + side (2 4gaguge and 2 8 gauge) you can use it instead of a distribution block if you have 2 amps.
