Heavy duty weather proof enclosure for Battery powered energizer and battery. Don't let technology leave you behind. Solar energy is going to be a big part of the future, and we have incorporated this technology into our product line. We sell 'solar setups' for our DC/Battery line. If you use a DC/Battery powered charger, you understand that the battery will deplete itself over time. Our solar setups will keep the battery charged, and keep your fence functional.
