The larger the less resistance. Use marine grade tinned cable with crimped insulated lug ends the correct size. You can have special cables made find the proper length and size of lugs on the ends. To be safe size the cable larger than the cable your replacing. Search custom marine battery cables they normally have common sizes or you can special order the cables.
