Ive decided to put my entire, ready to ride, efoil project up for sale. This is the same setup I had for sale a few months back before I chickened out and decided to enjoy it for a little longer before parting ways. This thing has been a labor of love and has evolved from multiple prototypes over the last 4+ years of trial and error (and lots of help from this forum). At the moment, the board is totally functional and ready to ride. It is tons of fun but adulting is forcing me to prune down my hobbies and toy collection.
First things first… as you probably know if you have spent some time browsing this forum, these boards are never finished. There is continual improvement and tweaking that can be done. While this board is currently ready to ride and has been really reliable over the last 20 or so sessions I have had on it, I am selling this board as a project. It’s pretty dialed in at this point but is not a $12,000 Lift board and as such comes with no warranty. Be prepared to do some amount of tweaking and garage engineering of your own. This forum will be an awesome resource.
- Powered by a Flipsky 65151 motor and aluminum prop. 3d printed mast clamp and rear fairing (NO PROP GUARD)
- Flipsky 200A water cooled ESC
-Closed loop freshwater cooling system. Onboard pump circulates anitfreeze+water through ESC and to an external radiator mounted flush with bottom of board.
- Maytech waterproof remote with wireless charger. Display on remote configured to show things like voltage, current, RPM, battery and ESC temps…
- Custom electronics rack with coolant reservoir. All electronics and batteries are located in a single waterproof box.
-Custom board. 5’4"x31". Started as a SUP and reshaped so it has tons of volume. Recessed battery box and motor connector access panel. Drop-in radiator. Battery box and radiator can be easily removed together to make the board a lot lighter and easier to carry.
- The foil setup consists of flat garolite foils and aluminum mast and fuselage. I cant remember who made these but I bought them on ebay a few years back. Super durable. Despite the flat profile they are actually pretty stable and (this really blows me away) efficient. I can cruise on the foil while only drawing around 35A.
- ride time is around 40 minutes, 5-6miles on average with my two custom 6S8P 26Ah packs (connected in series for 12S).
Will also consider selling batteries with this for an additional price even though I currently use them for my Ebike as well as this board. Batteries are two individual 6S8P Samsung 18650 30Q (genuine) packs. Spot welded using Kweld and solid nickel plates (not skinny strips). The cells are mounted in a 3d printed chassis with cells spaced out to help with cooling. These battery chassis have removable covers in case the cells ever need to be serviced/ swapped. No BMS. They took two iterations and FOREVER to build lol. Can also include a custom charger with these packs which can charge both batteries at once at 15+A each (I usually charge at 5-10A). Currently, the batteries have about 20 cycles on them.
Since the last time I had this posted, I have added some new features.
-Aluminum prop (works great).
-Battery temperature monitoring system that measures temp of the inside of the pack, displays this temp (along with ESC temp) on the screen on the remote in realtime, and will automatically pull back power limits if the battery (or ESC) begins to get too warm (I have not hit any of these limits while riding yet).
I have close to $2800 just in the major components alone (not including the obscene amount of money spent on previous builds that went up in smoke to get this board to where it is now along with the literally hundreds of hours of design work, shaping, wiring, crying, and 3d printing, waiting for parts for months etc…). I am asking $2500 for everything BUT the batteries and charger. I can also throw in some older Alien ESC’s and motors and whatever other spare parts I have. Will consider selling the batteries and charging system for an additional $600 (less than the cost of cells, chargers, and materials). I will also consider trades for other cool stuff related to surf, water, sailing, jetskis, a one wheel (or other cool eskate gadget) + cash. Located in Wilmington NC. Local pickup only. DM me for more pics. I have a ton. Thanks for looking and sorry for the repost. I figured this would be the least confusing way to get this posted back up.
