Maybe you can put a series of diodes in series and in parallel but the
other direction to reduce the voltage.
H-bridge +- +- +- +- motor H-bridge
-+ -+ -+ -+
Good luck,

| On my first robot, I just took a resistor in-line and used that. It got very hot, though, and didn't work evenly (some of them must have started to burn out before the others did....) (26 years ago, 22-Dec-98, to lugnet.robotics.handyboard)
