Where did you buy this charger ? Any link ?
This is what I bought. Decent quality + dust/water resistant + quite operation. Ideal for eFoil!
They can set you any voltage you like when you order it. But you can not set yourself, I tried to reverse engineer it but no luck to change the voltage. They are not willing to help with that remotely, but yo can send it in and they change it for you.
That is a really nice catch ! Been dreaming charging my battery through the board surface using a waterproof connector like these (as you charge a car). Would anybody know how they are called and where to find them ?
