The range will depend
. . . on what battery setup is installed and what conditions the boat is operated under.
First, the low-power models are designed to operate efficiently at or below displacement speeds. Therefore wattage use rises dramatically when attempting to operate in the range of speed near a hull's maximum displacement speed and will quickly deplete the battery.
Second, the Torqeedo control includes a computer that continuously updates a display of the calculated range using GPS and battery condition for the operators convenience and safety. Like any energy system with limited available "juice", faster consumption results in lower range. You can contact us for more information.
- Five-2 with 4 AGM lead batteries at 100 Ah each: 5 mph for 6 hours; 30 miles.
- Six-2 with 4 AGM lead batteries at 100 Ah each: 5 mph for 5 hours; 25 miles.
- Six-1 runabout has 25 kWh of storage in its lithium bank, Its motor is about 50 kW at full power. Doing the math: 25 kWh / 50 kW = .5 h or 30 minutes of full power run time. The boat goes 27 miles/h and 27/.5 = 13.5 miles at full power. HOWEVER, run time at no-wake speed (6 mph) is about 10 hours which indicates a range of 60 miles.
Furthermore, your results will vary due to temperature, wind, waves, number of passengers, bottom fouling, etc., because of the added drag or benefit those variables bring.
