Picked up 24 meters of 1/2" Black Braided Expandable Wire Sleeve on Amazon for $26.51CDN (shipped). I've replaced the 15' of 10 AWG wire with 40' of super-flexible 8AWG oxygen free fine stranded copper wire from Ennis Electronics eBay store for $55US (shipped). I've replaced the 2 pin SAE quick disconnect plugs with soldered Anderson style SB50A style connectors from iLooke's eBay store. Eight of the connectors with terminals cost $15US (shipped). The SB50 connectors handle up to 600 volts at 50 amps. More than adequate of course, but so much easier to connect and disconnect.
