Bright Way's break away kit BWK2353 does NOT include a 5-amp-hour battery. This BWK2353 break away kit is a system that will bring your trailer safely to a stop. When the breakaway cable detaches from the switch, the trailer's electric brakes will be activated.
Note: A breakaway system is required by law in most states for trailers that are equipped with electric brakes and have a GTW of at least 3,000 lbs.
