Building my own batterty cables

Here's a little more detail on the crimpers: Unboxing video / intro

I have quite a few pieces of cable left over from adding inverters to all my RVs, so it was time to buy my own crimper and make use of the cable I've had on hand.

About any size, any length, any termination.

I'm in the "go to welding shop" camp. Had to create a "cable manifold" of sorts when I went with a pair of 6 volt golf cart batteries. Went with the biggest gauge they had. LOL, they charged me a 12 pack of beer.

Nope, more. Eleventy-billion

The large cables are for my Victron Inverter project

You can also go to your local wholesale/retail welding equipment dealer and use industrial quality welding cable/terminals.

The dealer will have many gages (reels even) of black welding cable and a selection of terminals. Welding cable is very fine strands which are more flexible than standard automotive battery cable and the insulation is also very flexible and resistant to abrasion/chemicals. As well as a assortment of shrink fit.

Most suppliers will for a small $ amount crimp on the terminals and apply shrink fit etc.

Remember, measure TWICE and CUT ONCE!

Also if you have a scrap of steel approximately 1inch by 2 inch wide by 6 or 8 inches long available, drill a 3/4 to 1 inch diameter hole close to one end (must be large enough for the widest end of the terminal to pass thru) then drill and tap a 1/4 - 20 or a 5/16 - 18 hole 90* from the center line of the big hole. Clamp your tool in your shop vice, prepare one end of the welding cable/terminal place it thru the large hole, tighten the bolt and you have hand dimple clamped the terminal to the cable. (looks better than the “old” chisel/hammer method)

I clamp the crimper to the workbench with quick-grip clamps. Put the terminal in the crimper and tighten it just enough to hold the terminal without smashing it. Hold the cable in the terminal and crimp it with your other hand.

Putting the terminal in the crimper first also makes adding a terminal to a cable that's already in place on the trailer.
