Good value for the quality of these copper cables. Cut them to the length I needed and put a copper eyelet on one end. Wire size works good between my Victron solar charge controller and the batteries. Wire gauge will be able to handle the wattage much better than what I was using. They look much more professional than the old cables I was using also!

Be safe and always calculate the gauge wire are you need, don’t cut corners.

Good quality solid copper 4 Gauge wires in red and black. Avoid aluminum wiring that has copper plating so looks like solid copper but can be dangerous if used in heavy load applications. Copper is expensive but required if amperage is high.
