For most applications you can choose between bfs Plug III and  Plug IV.


With its unparalleled variety of floats that can be combined with the bfs plug, we are able to provide watering systems for any type of battery and in any area of application. This ensures that electrolyte levels can be adjusted perfectly. Our floats are offered separately from the plugs – a strategy we chose to help keep your capital costs and inventory costs low.
