Battery Watering Systems for Cleaning Machines and Street Sweepers: A Truly Clean SolutionFor the most common types of battery blocks bfs offers Plugs III and IV with bayonet or clip-in connections. One great advantage of the clip-in types is the short time it takes to install the plugs on the battery. A particularly effective solution for deep cycle batteries is our Triple Unit X4N320, which was specifically designed for certain 12 volt batteries.
