Re: golf cart battery installation
The quality of the crimps on the cable lugs is important, and making a good crimp can require an expensive tool. So if you weren't already set up for this, consider ordering the cables from genuinedealz.com, who will sell you marine grade cable with proper crimps installed, to order, for about the same thing you'd pay for the cable and fittings locally.
Some cheap rope cut up, or a tape measure, will make sure the lengths are right when you order. And of course, provide for proper primary fusing right on the battery bank at the same time.
