Of course the OP can hookup the batteries direct to the battery with alligator clips or via a connected harness and avoid that 10 amp fuse.
It has been reported in this forum that the actual side connect wires are actually 10 gauge wires which means that they can safely carry 30 amps (verify first). So theoretically, the 10 amp fuse can be replaced with a 30 amp fuse.
