Battery Optimization Systems actively shuttle energy between batteries to keep "the pack" balanced, increasing battery strength and longevity. B.O.S. shuttles energy as needed between batteries wired in series to ensure equal voltage before, during and after charging. Keeps packs balanced, enabling maximum performance, and quadruples run time on the water. Battery Optimization systems successfully extend the life of each battery in the pack as well as increase run times.
