No 2old, Luna doesn’t carry any coiled/spiral/stretch cables (that I can find on their site, and they don’t respond to inquiries very well.)
They were actually the first place I checked, because they did stock a bunch of different stuff I needed that was unavailable from the other Bafang dealers and shipped it lightning quick. That 8” 5-pin cable I ordered just a couple days ago is already out for delivery, along with another 52V charger. Woohoo!
Still can’t find any 2-conductor 12 AWG coiled cables anywhere, seems 18 gauge all that’s available.
