Flow-Rite a Pro-Fill universal deep-cycle battery watering system designed for (8) standard 6V batteries.

Each kit consists of automatic shut-off valves that replace the existing vent caps which are interconnected with tubing, making the process of filling your batteries a breeze. Flow-Rite makes battery maintenance easy with a full line of Single Point Battery Watering systems and flip top watering caps.

Fill batteries faster, safer, and more reliably than ever before with Millennium Evo, Pro-Fill, or Qwik-Fill on-board watering systems. Each application specific system consists of automatic shut off valves interconnected with tubing that replace the existing vent caps. A quick coupling allows the system to be connected to a water supply.

Once connected, water flows into each cell until it reaches the correct level. The entire process takes just 30 seconds per battery!
