[Hackability] battery voltages in mobility scooters

I'm working on a DC-DC converter / battery charger circuit with Liz to act as a
regenerative brake for mobility scooters, and it's an explicit goal for the
design to be easily adaptable on different models. I've a question -- what is
the highest battery voltage commonly used? I need this information in order to
properly select the DC-DC converter controller and the power transistors for
the DC-DC converter. I know 24 volts is a voltage that's used (two 12V
batteries in series), but are there any mobility scooters that use higher
battery voltages? Are there any that use voltages that are higher than say,
36 volts? The end goal is to have a model-agnostic regenerative brake
controller that needs minimum customization (beyond, of course, desired
voltage output) for each individual installation.
Also, if you'd like to get involved, let me or Liz know!
