Hello, I’m Gabe Vianna and I’m trying to figure out how to build an electric surfboard. I know this is an efoil forum but the concept is more or less the same. My goal is to have a board that can easily plane above the water at around 10mph in 1-2ft waves. I looked around and found some parts that might do the job I don’t know how much power I’ll need or if I’ve got the right electronics so I’d like to hear your opinions about the setup. The motor and ESC are sourced from Alien Power Systems with the motor being an 83100SW 7000W brushless motor at 130 kV. It’s a large motor but I’m planning on doing a direct drive system so I think I need the extra torque. The ESC is an Alien 300A 3-12s ESC. Again I’m not sure if this is adequate or overkill. I’m planning on running a 6.5-inch diameter prop which will be 3D printed. Larger proper might be better due to the high torque output from the motor. The system will run on 12s and I’ll be buying several 4500mAh 6s 60c batteries from amazon and wiring them in series. I’m not sure but 8 batteries in pairs of 2 might be enough. (gives me 18,000mAh) I have an old SUP board that is in rough shape which I can mount the electronics to however it is a very large and heavy board and ill have a very rough time steering it and it might be slow. I’m thinking that buying an old surfboard and modifying it is a better bet.
