DIY Your Own Battery Cables

Get your DIY Parts here for building your own battery cables.

Parts. Just Parts…

Some people just want to buy parts and assemble cables themselves.

Using the button links below you can purchase wire, battery terminals, and lugs.  We stock a larger variety of battery cable lugs than any of the large auto parts chains.

I’m adding more to our inventory all the time so if you don’t see what you want please email me.  I may have it in stock and just not yet listed it.

Watch this video to see how to build your own custom battery cables using quality parts.


The manufacturer of the ends recommends crimping as the best way to attach ends. If done right, with good equipment, the crimp is so tight that there are no air gaps and no room for the solder.

I offer a few styles of crimpers. I don’t really recommend the cheap hammer-style crimpers, but they’ll do the job if you’re not too picky. They also seem to “wear out” and start binding after several uses.

Should You Solder?

Soldering can be difficult to do right.  if you don’t get the wire hot enough you’ll get a “cold solder” joint that is a poor connection electrically and mechanically.  Use too much heat and it is tough on the insulation. The solder can also wick up the wire destroying the flexibility. Soldering also requires flux, hazardous lead solder, and solvents (for cleaning the flux).

If you are going to solder, we recommend using solder pellets.  You can buy them here.

Picking Your Specs

Items are spec’ed by wire gauge. (see Technical data for what the sizes mean).

Battery terminals are also specs as positive or negative (positive is slightly larger). Lugs are also spec’ed by bolt hole size.

Because of the large number of parts, I’ve split this page into several categories…
