Hi, everybody, new to the forum. I have a 2013 Aerolite 185E. The original battery is on its last leg so I bought two new 12V deep cycle batteries that I will parallel. I bought 6-gauge cables to parallel them. Is 6-gauge adequate? I don't plan on drawing more than 15A.
#6 wire at 12vdc can carry an enormous amount of current as shown by this chart. Your battery circuit should have a breaker or fuse protecting it. That fuse/breaker rating will be the maximum load your batteries and wire will ever see.

Appreciate your knowledge and experience.
Do not parallel with the old battery as the old one will draw down the new one. (at least read that someplace).

Good advice. If your first battery is fairly new (less than a year or so) and hasn't been damaged by excessive deep discharging you might be able to get away with it. Otherwise you need to replace your batteries in pairs or groups. A weak battery can pull down a stronger new battery pretty quickly.
