    Exactly what I need to tie my 2 RV house batteries together. I dont need h heavier gauge cable for this application, In my case, each battery has its own set of positive an negative cables to serve half of the RV. These cables, therefore, are used for load balancing and battery charging only.

    Exactly as requested, and unlike some items that you order online and show up not exactly like the picture or whatever, these were sweet, right down to the heat shrink on the terminals.

    These are really nice cables. You can feel the difference in the quality compared to cheaper cables. I own an RV repair facility and have worked with all kinds of battery cables but these by far are the best in value I have used. Highly reccomend!

    Purchased two for around $12. Way cheaper than buying it in town where it is $10 for one cable. Good cluck for your buck$$$$$

Pure Copper Tin Coated Cable Lugs

Heavy Duty

WindyNation"s pure copper tin-coated cable lugs are heavy-duty, pure copper, and are ideal for marine and humid environments because the tin coating protects the copper cable lug from corrosion and oxidation. If you need cable lugs for an outdoor installation on your RV, boat, car, truck, golf cart, off-grid wind, or solar installation, then WindyNation"s tinned lugs are your go-to choice!

Splice

Cables are precisely cut and stripped on automated robotic cable processing machines.

Crimp

Cable lugs are attached using a 6 ton pneumatic crimper with custom dies, resulting in an ultra-strong, non-removable crimp.

Insulate

After crimping, polyolefin heat shrink tubing is applied to eliminate the possibility of moisture or chemicals penetrating into the lug/cable interface.
