After doing some more research, I stopped by the Homedepot and grabbed a couple of copper grounding posts (Homedepot has lots of products for this kind of high-current applications. Although they are mainly meant for home builders, these connectors can easily be adapted to any circuit designs). I then soldered one side onto the circuit board and soldered short 10AWG wires along the traces (I made sure that the traces were as short as possible) and then screwed in the 10 AWG wires for load connection.
From my load tests I can say that this had worked out quite well.
