If you're using these for speakers over 50W, I highly recommend connecting them in series (e.g. a 50W battery). There are 3 connections on the board for this, all in parallel. Got two extras for my 75-100w speaker to extend the run time. My only concern is that the wires are a bit flimsy for me. However, they help twice, but still.
