Here's a pic of a simple, small fuse setup. ATM fuse, female blade terminals on wire ends, heat shrink terminals. Almost any value fuse is available.
Good advice, but the Leo DMD will protect with its own current limiting output protection on the FET's. The max momentary surge on the FET's is about 20A, so continuous would be about 10A max, but RMS continuous would be more like 7A under stall.
