Hi!
After a few long years of gathering parts, learning and testing, I have reached the finishing stages of my eFoil build. So naturally I would now like to share it with you
This is a 48" carbon fiber board, built with
- 14S7P LG M50LT battery
- MakerX HI200 75V VESC based controller
- Flipsky 65161 120kv motor
- FR 6" 3-blade prop
- Gong 65cm V2 mast
- Curve MT and Veloce MT front wings, Surf 40cm and FAST 40cm stabs
- Metr Pro CAN for logging, with MRo u-blox NEO-M9N GPS
- Maytech controller, with some additional waterproofing
- 150A main fuse that also acts as a power switch (100A would probably be a better choice)
I designed my own FS65161 Gong mount: FS65161 motor mounts for Gong V1 and V2 masts
The 14A7P battery is made with LG M50LT cells that are not commonly used with eFoils. My battery simulator said that it would work, so I took the chance and used these cells. They are rated at 7.2A each when over 25 celsius, and 14.4A when under. Turns out that I never exceed 7.2A per cell even during takeoff. The battery runs cool and performs really well. I am very happy with it. More info about the battery build here: DIY 14S7P battery build in a Pelican case
