4 Gauge Marine Wire 4 AWG Marine Grade Wire Include 4 Gauge 20FT Red & 20FT Black,4 AWG Tinned Copper Oxygen-Free Cable for Automotive Boat Camper Trailer Speaker Battery Lighting Solar Panel Outdoor

I used this 4 AWG marine wire to run power from the engine compartment battery to the helm for an amp install, and it worked perfectly. The wire is high quality with thick insulation, yet flexible enough to route easily. The tinned copper is ideal for marine use and should hold up well against moisture and corrosion. Everything has been working flawlessly. Great option for marine wiring projects.

Pretty good wire and a lot cheaper than the local hardware store

Perfect for relocating a trolling motor battery from the bow to the stern. Boat is faster now having less weight up front.

Purchased this wire to mount dual batteries in my boat. Upon opening the package you could tell this wire was of good quality. Very flexible wire

I bought the 2/0 AWG version of this marine-grade tinned copper battery cable for a 560Ah LiFePO4 RV battery upgrade project. I needed heavy cable for the battery-to-bus-bar wiring, and I specifically wanted actual tinned copper, not CCA or mystery metal pretending to be copper in a trench coat. This cable worked very well for my project. The conductor is made up of lots of fine tinned strands, and it crimped cleanly into my 2/0 lugs with a hydraulic crimper. The finished cables feel solid and substantial, and I had no trouble using it for short high-current battery runs in my RV setup. The jacket feels thick and durable. That makes the cable feel slightly stiff compared with super-flex welding cable, but that is not necessarily a bad thing for an RV or marine-style battery installation where abrasion resistance and durability matter. It bends well enough for battery compartment routing, but it is still big 2/0 cable, so do not expect it to snake around like speaker wire. A few quick notes: • 2/0 AWG size worked well for my RV lithium battery project • Tinned copper strands are what I wanted for corrosion resistance • Thick black outer jacket feels durable • Crimped cleanly into 2/0 lugs • Good for battery, inverter, solar, marine, RV, and off-grid DC wiring • More substantial than cheap automotive cable • Not the cheapest wire, but good 2/0 tinned copper cable is never exactly bargain-bin stuff It does feel pricey at first, but after shopping around for 2/0 wire that was actually tinned copper and marine grade, this was one of the better options I found for the money. For my 560Ah RV LiFePO4 upgrade, it did exactly what I needed. Overall, I am happy with it. It is heavy, well insulated, crimps nicely, and gives me more confidence than using cheaper non-tinned or questionable battery cable.

Wire seems OK. I'm disappointed that the insulation temperature isn't printed on the wire jacket like it should be. The description stated 105 C, but I can't trust that since it isn't printed on the wire. I'll just have to hope it doesn't melt. The insulation seemed softer than I expected, I guess time will tell... Otherwise it is flexible enough and should work OK. I will be putting 50A through the wire soon after installation. I'd give 5 stars if the information was printed on the outer jacket like the best quality wire always has.

has worked well for re-wiring my old bass boat. no complaints just wish i bought a bigger roll

I use 10GA wire for my solar panel installations, and I need good, stranded wire for this purpose. This wire is actually 10GA as advertised which shouldn't be surprising but I have purchased "10GA" wire from other sources only to find the conductor is barely 12GA at best. You won't go wrong with this product if you need stranded 10GA wire.

Muy buena calidad, identico al #14 y es #16, estañado resistente a la salitre

Muy buena calidad

Excelente producto
