Does the battery (front) compartment itself have outside vent(s)? If so, are they located?
Also if you are using 4 six volt batteries, which Century Plastics battery box is best and fits comfortably? The case that holds 4 batteries; two cases that hold two batteries each (side by side); or two cases that hold two batteries (lengthwise)? I'm asking because I don't have mine yet. The cases are linked below.
