Battery Boxes that are Vented for your RV
Battery boxes that are vented include a kit (wall connector, outside vent and 9" hose) for inside installations. This vented battery box also has a hole at the bottom to help with air circulation. This product meets the RVIA Code. NOTE: Since the top and bottom sections of this box are identical, the hole in the bottom section also has a protruding flange so that it will not sit flat on a solid platform.
