4 AWG Gauge Red + Black Pure Copper Battery Cables Power Inverter Wire Set for Solar, RV, Car, Boat, Automotive, Marine, Motorcycle with 3/8 in Lugs (4 AWG, 1.5 Feet)

Excellent connectors never have to worry that they will fail. I would rate this as a Excellent buy.

I was able to repair a 12000 lb winch that intermittently worked and cables were overheating . Works like new now.

Good quality and flexible

Used positive cable to replace oem cable from car battery to starter and alternator. Also replaced the cars ground cable with this. Work great.

When I bought these I didn't plan on using the terminal lug (rings) that were supplied, I just wanted the cable because I planned on installing a quick disconnect connector on one end and completely different size terminal rings on the other ends, so I cut the ones off that came with the cables. I found that on the inside the copper looked to be really pretty good, very fine MASSIVE number of strands, the actual wire (cable) itself would be VERY flexible (much more so) if the cable had a higher quality jacket on it, but I can see that if the cable had a silicone premium jacket it would also raise the price of the cable. What's on the cable is some type of PVC/plastic that make the cable somewhat stiffer than say a premium Silicone Jacketed Welding Cable. I will say that for a crimped on terminal rings (not soldered) they they seemed pretty darn tight. Some reviews state that the terminal rings are "well sealed" (???) I will say this, they are dressed up pretty nice with heat shrink, BUT! its just the basic heat shrink not the Glue Lined marine grade 3:1 heat shrink, so they're Not Sealed and if they're used in Lead Acid battery compartment the ends are NOT SEALED so expect corrosion to happen if not regularly inspected and cleaned and service. I gave them a 4 star rating for the copper used in the cable, if I was to have used them as is I would have probably gave them a 3 star rating.

Installed these cables with my new lithium batteries. Perfect.

Nice build quality. Very satisfied.

Don't be fooled by the picture, these cables are short! I am using them for connecting an inverter to a battery, and the length is perfect. These are not flexible cables like a lamp cord, they are stiff like 6/2 NM-B Romex. The lugs are sturdy and well sealed to the cables.
