Around a few months ago i came across efoiling and was absolutely stunned. So all i have been doing this past weeks is reading this forum and planning my own build. I still don’t know much so please riducule me when i make an obvious mistake. Any feedback is appreciated!
I plan on using the flipsky 65161 120KV, the flipsky 200A 60V esc, the erayfoil A1 remote, a 12s14p battery and the Gong allvator curve L. I’m planning on cooling the ESC with water inserted from the front of the motor clamp and pushing it up with the presure. If that doesn’t work i will have to use a pump. The ESC will also be put in a aluminium box.
I would love to use recycled cells for my battery as that would cut cost massively but i also don’t want to burn my house down. I found this site where you can get around 250 used 18650 cells for only 80 euro! Lot of 250+ Cells) Commercially used in Laptop Battery packs for Cell – Battery Clearing House
I would rather buy from a local online second hand shop because there you do get one type of cell instead of a bunch of different ones.
I like to know if anyone has experience with used cells and if it’s worth the hassle. What are the things to look out for? If i buy used cells i want to make induvidual fuse wires like @Flightjunkie and others did in this post. Building an 18650 battery with individual cell fuse wires
Flightjunkie uses fuses on both sides of the battery but would only one side not be enough?
This is a pretty basic build but i do plan to improve on safety. I want to mount a cord on the front of the board. If the cord looses tention the motor will stop. One of my ideas was to have an elastic cord mounted on the board on which you attach de cord what will be held in your hand. In the board and in de middle of the elastic cord you will have a magnet that will be attached to a wire. When the rope looses tention the magnets snap together and close the circuit triggering a relais cutting the power of the system. A quick drawing of the possible system:
Is it possible to do this without the relais and use the ESC to cut of the power? I came up with this because i couldn’t find a simple tention switch. Does anyone know if they exist?
I know that these are a lot of questions but any help is welcome!
