Another great idea, I ordered extra 2/0 cable for that reason. The boat is getting all new marine grade battery cables in addition to the second battery. I got some of the connectors in, but still waiting on the bigger pack that I ordered separate from the cables. You are correct about the current being reduced with corrosion. It also looks like only half of my cable is crimped on the boat currently, which would also restrict the current. Ordered the correct sized ones for 2/0 cable, looks like the original owner had them replaced with ones that were not large enough to crimp the whole cable. You can see on the negative cable in the first picture. Great advice on this forum, I love all the knowledge in these boats and the willingness to share here. Thank you everyone!
