Taking that idea one step further, what does anyone know about regen from a Torqeedo? I vaguely remember somebody saying something in this group about this, but I can't remember exactly what was discussed.
Torqeedo makes a big deal about their motors being more efficient because of the rare-earth permanent magnets, so they should also be a more efficient generator (I think). And they come in 48V. Even the most expensive Torqeedo is significantly less than the Wattandsea offering.

If there is excess voltage, it will be clamped by the battery and can be measured as current. When the prop slows, the diode will keep the juice in the boat. Â Turn the prop into the water current, perhaps, to get cleaner flow over the prop. Swap the prop for two airplane props staggered on the same shaft to increase the swept area.Â
