Looks like a nice setup. Interested in how you go about routing those cables.... When you assemble the connections if you decide to crimp any of them I'd recommend Soldering/Tinning the ends of the cables first; then slide the ends on; then Solder (fill the connector ends w/solder) using a torch (be careful not to burn the insulation). Then crimp the eye connectors and finish with the heat shrink tube. Soldering (in addition to crimping) will provide the best/longest lasting connection possible but you're going to have use a torch to get it hot enough. No way even a large electric heat gun will work - I tried. Recommend practicing on one of those crimp connectors and short piece of cable to get the technique down prior to assembling the main connections. If your battery cables are the screw style I'd still solder/tin the ends to make them stiff before inserting them into the ends and tightening down the screws.
