ELECTRIC BOAT PROPULSION - THE FUTURE OF MOTORIZED BOATING!
       
The following calculation and information is for indication only and is not binding or can replace a quote by the supplier or technical advice by a specialist. The results base on values archieved by testing and can vary depending on the type of hull, weather, battery type and age, installation method etc. You can change the values as often as you like. All costs include GST in Australia (10%). Prices for indication purposes only and do not include installation costs. For actual prices and technical information contact all4solar or get the latest information from the website. Make sure your boat is designed to carry the weight for motor & battery. Prices and technical information subject to change without notice.
       
CALCULATION SHEET FOR ELECTRIC BOAT PROPULSION

MOTOR & BATTERY TYPE
Area of operation
       
Motortype
Batterytype
       
Speed per trip in minutes at 100%
Speed per trip in minutes at 75%
Speed per trip in minutes at 50%
Speed per trip in minutes at 25%
NOTE: To get to a certain speed needs more power than to keep this speed. So the calculator takes this in consideration (90%) when calculating the battery capacity as well as the efficiency and hourly output capacity of the batteries
