Improving Contact Area on Welded Stud Pads

Well, this smaller contact area has put my plans for using the on stud blue seas fuse blocks i have, on hold.

i'm currently using them on my current lithium single battery setup, but when i received my order of new stud blocks yesterday, i noticed that the mounting hole is 10.3mm :unsure:, so thats annoying as i planned on each 12 volt 304ah packs individually fused connected in parallel together via a 30mm x 4mm copper busbar (i plan on tinning the copper)

i'm guessing that these copper washers will be the only way to solve this issue, i prefer the on stud fuse blocks over running wire to a mounted fuse block
