The Lift Foils YouTube channel is also now offering a complete How-To eFoils series (Maintenance, assembly, safety, practice… ). They took their time but here they are !

You can post here your info about Lift technical choices: motors, ESC, cooling, connectors, wireless…

That is a very nice build.

Totally high end product. There’s a lot of thought and work in their board. Wish the pricing was more reasonable, but you usually get what you pay for. Hopefully they sell a ton of them

Been surprised by the size of the battery charger seen in Initial Setup - Video #1
A really High-End recent (2017) one from the Canada-based Delta-Q, worth 500+ USD.

This charger contains Pre-loaded lithium charge profiles supporting various lithium-ion (Li-ion), lithium polymer (Li-Poly), or lithium iron phosphate (LiFePO4) cell and pack capacities.

It is possible to find cheaper 48V chargers such as the ones used in 48v Golf Carts but the recharge time is 4 to 6 hours instead of 2 hours (15 amps instead of 25).

I couln’t help looking at the battery life aspects. Lift have probably chosen Lithium-ion (Li-ion) cells because they have a better energy capacity, are cheaper and safer (explosion risk) than Li-Pos. However, both have a Recharge Life of 300 – 400 cycles, say 350. This means the battery pack should be renewed every 3 months in a school or rental place if recharged 4 times a day ! That’s a serious operational cost to take into account in a feasibility study ! From 8 or 9 am to 6 or 7 pm, only 8 persons riding 30 minutes each can use the board every day. That’s not many to make profits.

These videos are great insight into the Lift design.

Does anyone know the motor connectors they are using?

The idea I had in mind when creating the thread … a place where users could post their retro engineering info even if I am aware that users who can spend 12.000 USD in such an equipment are not legion on this forum … Hopefully, as soon as the Lift eFoil appears in various places across the globe, comments and picts with valuable info for home builders should pop up …ESC, motor, cooling, remote control, …
