4 Gauge 4 AWG 10 Feet Red + 10 Feet Black Welding Battery Pure Copper Flexible Cable + 10pcs of 3/8" Tinned Copper Cable Lug Terminal Connectors + 3 Feet Black Heat Shrink Tubing

I bought the 4 gauge wire to make new battery cables for my motorcycles and am very happy with this wire. First off, it is very flexible, allowing me to make sharp bends easily. Second, the included lugs and heat shrink fit perfectly.The only problem I ran into was my hydraulic crimping tool didn't have the correct size die, so I had to use one slightly smaller than I would have liked and caused some sharp edges in the crimp. I just filed down any ridges because I was sure it would have ended up rubbing through the heat shrink. To avoid this problem, buy a better crimper than I did that has correct awg dies or don't do an Incredible Hulk impersonation on it.I ended up making new positive and ground wires for my riding mower, 4 wheeler and plan on making several more for other street bikes. These made a huge difference over the old corroded cables they replaced.When it comes time to make more battery cables, I will definitely use this brand again. Couldn't beat the quality and price.To sum it all up: It's great cable at a great price and you should buy it.

The crimper doesn't lie, if you order 4 gauge don't be surprised if you get 6 gauge. For my use case, it was not that big of a deal as the cable run was very short, but if you need 4 gauge based on voltage and distance, double check the cable before using it.

Used this wire/lug kit to make some various length cables to add a second battery to my pontoon boat along with a master switch and an automatic charging relay. The tin plated copper lugs are good quality and fit the 3/8" studs on my equipment very snugly. Fit the 5/16" studs loosely so I used stainless washers. The wire has extra fine copper stranding and is nice and flexible. The wire insulation is soft and not highly abrasion resistant, so be mindful on wire routing and proper securing. I highly recommend NOT using the included heat shrink for any outdoor/mobile application, and instead use a good quality adhesive lined heat shrink to help seal the connections. Also highly recommend using a hex die crimper (hydraulic or bolt cutter style).

I did not have a crimper so I solder the connectors on using a old large soldering iron. Still working on connecting up my inverter, but I am pleased with my connections.

Measured the correct thickness wire. The outer coating doesn’t want to melt or burn, which is awesome. I’m using this as a way to connect some larger batteries to a monster UPS, so soldered the connectors on as I didn’t want to buy a crimping tool I’d use once. No issues soldering so long as I used electrical flux prior to applying solder.The wires are flexible and, well, awesome.

This 4 AWG wire was used to connect big batteries together. The wires are color coded red and black for NEC standards for DC systems. The wire was flexible and easy to use. I recommend this product.

I didn't give it 5 stars because the package was short 2 cable connections. There should have been 10 but only had 8. I had two purchase two more at $4.50. So it cost me more then if I bought everything local.

Nice flexible cable. It’s doesn’t seem to be 4 gauge wire. I couldn’t even find a wire size printed on the cable. I used 6 gauge lugs on the ends and the fit perfect. The lugs shipped with the wire are a full size too big. Expect 6 gauge wire if you order 4 gauge.
