Mighty Mule MMB200 Battery Enclosure for Gate Openers – Outdoor 12V 7Ah SLA

Overview

Meet the Mighty Mule MMB200 Battery Enclosure Kit, a rugged outdoor storage solution crafted to keep gate opener power components organized and protected. This enclosure kit is designed to live where your gate operates, offering a weather-rated home for the battery and wiring. Included is a 12V 7Ah Sealed Lead Acid battery (FM150), plus battery harnesses and the mounting hardware you need to install with confidence.

The MMB200 is built to accommodate up to two FM150 batteries, giving you additional runtime for busy entrances or overcast days.
