The Flite Controller display shows the remaining Flitecell power as voltage, remaining time and range (based upon your power consumption). An efficiency screen on the controller displays watt hours per kilometre, to guide you to speed up or slow down to maximise your ride time and range. In addition, the specially configured Battery Management System will reduce the power available when the Flitecell is close to running out. This gives you enough power to motor slowly back to shore, but not enough power to foil. For safety reasons, you should never ride further from shore than you are prepared to swim.
