Brad,
I concur with Jack. Solder the ends with tight fitting (to the cable) good connectors and finish with a couple layers of quality heat shrink.
I prefer to use 4 or 6 gauge black welding cable (it hides better) and color code the hot ends to the battery and the load with red heat shrink tubing.
Be sure and use plenty of flux and adequate heat to do the job. I prefer using a micro gas torch to heat up the connector and flux with the connector upside down and feed the solder quickly so it fills up the connector. Let her cool slightly so she binds good and clean off any excess flux with a water soaked rag.
Is the Shorai battery Lithium-Ion cells?
I made my own battery utilizing 8 (eight) A123 Lithium-Ion cells. 4 cells in series produces a bank of about 13.4 volts. Two banks soldered in parallel doubles the amperage. It weighs about 2 pounds and cranks the 996 engine easily. Holds a fricking charge for a couple of months it seems.
These batteries are readily available on e-bay and the net.
Seal the connections with terminal anti-corrosive spray or grease etc.

The original cable is the metric equivalent (roughly) of 8-Ga AWG. I've put 6-Gauge on all my Ducs and it's more than enough. Also, if you want gas-tight connections, just solder 'em. You'll never, ever have corrosion or other voltage-dropping problems. 90:10 hard solder will hold it forever, or if you just gotta have the best, 20% silver solder.

Brad, try these guys. I don't think the have minimum orders.

I would think good 4GA would handle most lengths on the bike. The tough part is making good, gas-tight crimps without expensive crimp tools. An aircraft electrical shop, or auto electric shop would be able to help.

In order to make this work, I'm going to need to build longer battery cables, and upgrade them from the wimpy stock ones. From what I've heard on this list and elsewhere, waterproof marine connectors & wiring are the way to go.
