Two years after the first wiring diagrams were posted, what have we learned ? A circuit breaker in the battery box, a leash activated Reed Switch in the ESC box : would we do that differently today ? Maybe we should talk about that in “Safety with eFoil” ?

- a main fuse between battery and ESC ?
- activate current limitation if ESC allows it ?
- a 30 or 40°C probe on the ESC to trigger the water pump ?
- anti-spark FET based switches and where to place them ?
