4 AWG Gauge Red + Black Pure Copper Battery Inverter Cables Solar, RV, Car, Boat 9 in 3/8 in Lugs

Great cables. Bought for a new ground for an amplifier in my truck.

Used these to replace the negative battery lead and then splice the positive battery lead in my John Deere 790 tractor that had corroded and oxidized to the point that they prohibited the tractor to start, even with a brand new battery or while attempting to jump it. Im a big fan that these use lugs and have no exposed wire either.

I really like these. I bought a couple of different sizes for my 48-volt pontoon batteries. Working well.

Hooked my lithium batteries together

The cable is flexible, the connector sizes are proper. Can not advise for longevity. Purchased for lithium batter usage DC to DC charging on a RV.

This item is just as advertised . looks like good quality .

Used to connect 2 travel trailer batteries in parallel. Exact length needed, good fit, fair pricing, quick delivery.

These cables were perfect for our project, batteries charge as they should and I would definitely buy again.

Used to connect two deep cycle batteries in parallel on travel trailer. Connections are better than I expected. Wire is much more flexible than what came on my travel trailer.

Very nice flexible wire. Factory ends seem super solid.
