Lining a new battery box
I just built this pretty new box for our new setup at a cabin. I'm at the point where I need to line the box with something in case of spills, etc. I've been searching and pond liner is pretty pricey. Are there any other good options for lining the inside of the box? I'm not too concerned about the fumes because I have a 48V Zephyr fan that will be mounted on the top of the box.
