We use part #
7479K241 from McMaster. It's very flexible and much easier to work with. Doesn't leave that kinked look.
We used the Anderson connectors last year and had nothing but bad luck. It may have been that we just weren't getting good crimps on them, but we had a ton of problems with intermittent contact, even after going back and trying to fix the problem. Eventually we just moved to standard barrel terminals, which allowed us to take the wires off with slightly more effort, but no worries about contact problems.
