IMO 304 ah cells are too big for a cable connection, especially 3P. THat really depends on your power output on these cells. That thicker wire is just too hard to work within a tiny area, and when I-have worked in a small area, I''m left with a cable that looks like two lugs with a tiny wire between them, and it ends up not flexible at all.

The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2. The gradient of the “straight line fit” shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing the detailed electrothermal analysis.

Corrosion can be caused because the air used to cool the battery comes from the cabin that can be hot, cold, moist etc. When rebuilding always use a drop of Stabilant 22A on the nut/stud. Image supplied and copyright of Salvage Wire. In reality the connecting surfaces are not perfectly flat.
