Smart drive motors as generators are good stuff, they do tend to take a fair bit of energy to overcome the cogging effect from the permanent magnet rotors.
This can be reduced by spacing the rotor out a bit to limit the amount of magnet under the stator pole pieces.
I had a small creek with a 10 metre head, 50mm pipe but it was not capable of turning a smartdrive.
I used a car alternator, then adjusted the rotor current with a resistor to get maximuim output.
That worked well, as I only had a short run from the creek to my batteries.
Good luck with the project, I hope it works well
