K-Musculo #10 Red and Black Solar Cables 10' Long for Connecting Charge Controller to Battery Bank

I am not an expert but, the #10 solar panel cable perfect for charging batteries. Better than thin cable. The more thicker, the more solar energy goes through. Been working just fine for me.

Used these as extensions on my RV battery. Worked as expected. Thumbs up!

As described

Real good quality
