Hello, I am new here and looking into building my first efoil assist. I am looking at different batteries and amps they can deliver. I weigh 75 kg and am looking at about how much power I would need to get on plane. If I was able to produce 1500 watts would that be enough to get on plane or would I need more? This will effect my design choice and what I’m buying if I need more. Thanks for everyone’s help!
The power requirement will vary a bit based on board volume, total weight (rider+board), and then actual water conditions. Taking off into a headwind with some chop will take more power. 1500w is too low I think, I would want to budget 3000w. I haven’t looked recently, I think I’ve had takeoff power around 2.2kw (I weigh about 65kg,100L board and 1400cm2 wing).
There are some nice videos of the battery build topic made by @ludwig_bre linked in this thread
For a beginner I would recommend 2.5-3kW starting power and 1-1.5kW continuous foil power for a well-shaped board that glides nicely.
Thanks, I’ll make sure my set up is capable of at least 3000w. I appreciate the help!
I use around 1.5-2kw when foiling at 30 km/h with 1000cm^2 wing and close to 5Kw on take off. 105kg total weight and 95l board
5kW is a lot, I normally use 2.5-3kW, 110kg total weight 950cm2 wing, 80l board volume. With swell, peaks can go up to 4kW for takeoff.
On a 900cm foil at 78kg on a 50 liter board I use 950 watts to get up on flat water and 300-400 watts to remain on foil once up. If I ride my 1220cm foil these numbers decrease more.
wow thats the lowest consumption I have ever heard on this forum. What is you motor and esc and foil and prop?
I use the F 65161 and a gong curve 1400cm2 and run 1100watts cruising at 30kmh. Takeoff takes 3kw or more. I am 92kg. Using fliteprop on a fliteboard.
I am using a leopard 6362 105kv motor and a castle edge 40hv esc on 12s, using an axis 939 V2 foil. For the propeller I have found the Foildrive two blade prop to be very efficient.
