Crimp Supply Ultra-Flexible Car Battery/Welding Cable - 4 Gauge, (75 Feet Red/75 Feet Black) - and 5 Copper Lugs

These cables turned out to be the ideal solution for a travel trailer solar installation. I found that the finely stranded copper allowed me to run the cabling nicely beneath the frame of the unit and when it came to tight corners and sharp turns, this cabling had no troubles routing along the path. The jacket, while not impermeable, did manage to retain it's protection even after repeated dragging along rough edges. However, I would suggest that you use rubber grommets as I did if running along any sharp surface as before doing so, I did manage to scrape off about a millimeter of the jacket while pulling the cable through before installing the grommets. Here are the types of grommets I am talking about: 125pc Rubber Grommet & Plug Assortment - Includes Solid Plugs - Automotive, Airplane, Marine Applications Also, due to the lack of any spacing or clearance between the outer cable jacket and the internal copper strands, do not expect these cables to "flatten" out. They will maintain their round shape regardless of whether they are compressed. The copper lugs worked out great and were thick enough to crimp and hold nicely although I would recommend dipping the bare copper in flux before inserting, then crimping and finally, heating and applying solder to your connections in order to ensure a corrosion resistant connection in outdoor environments.

I'm up to my ears in a boat rewiring project. I needed a number of battery/power cables of specific lengths, and was growing increasingly horrified by how much custom cables actually cost. So I decided to make my own custom cables - I got some 4GA cable (this review), assorted appropriately-sized crimps, and a crimper/cutter tool combination, and then got busy.In the end, I was able to make a half-dozen custom-length cables for about half the cost of "professionally made" versions. It helped that I was a professional cable/harness maker in a previous life - I do know what I'm doing here. I'm also an engineer by training and profession, as well as a big MacGuyver fan - I take some small amount of pride in being able to get the job done, no matter what it is.There is certainly a trick to getting good big-cable crimps from inexpensive tools and parts, but it CAN be done. It just takes practice, patience, and a learning curve.

I purchased 10 feet of 2/0 cable and 20 feet of #4 cable for a RV solar installation project. The 2/0 is being used to rewire the batteries and the main feeds from the battery bank to ground and the main distribution panel. My shortest cable so far has been about 4" in length and the flexibility of this cable made this much easier to crimp on the fittings and bend it into position so electrolyte levels could still be checked without cable removal. This cable is easily cut with a pair of hand held Weiss wire cutters I picked up at a home repair store. I ordered on Friday and the cable was delivered on the following Tuesday. Very pleased with the product and the company.

I needed new jumper cables and dont like the expensive options cause of cost and hate the cheap stuff cause of length and life span. Solution make my own which I did and now got 30 feet of reach and better cables all copper wire not that aluminum wire coated with copper. I guess after a couple years of wheeling out in the woods you start to understand reach and quality.

Awesome quality cabling. I used this to rebuild the main battery and starter cables for my 1996 Ford Bronco. It was very flexible and was true gauge size.

This wire will connect the batteries to each other and to the main busses for the positive and negative.

Perfect ... needed long, flexible battery cables for second battery on my old truck. This works ... and price is favorable.

Excellent Cable - Very Flexible. Perfect upgrade for my old Wards POWR-KRAFT stick welder. While I love the cable and it works well, I do wish that I had purchased longer cables.
