[Electric Boats] Re: using a 36 Volt dc motor from a 48 volt pack

 

In my controller I can limit the voltage as a percentage of the battery pack voltage so if I had a 48v pack and set to 75% it would translate to 36v at full throttle. I actually run direct drive at 24v although my motor speed is rated for 84v x the no load speed constant of 45 rpm/volt. What's most important is the rated current at the peak voltage you choose to run at.

See chart here. Mine is a D135. These are the kind bed of specs you need from your supplier.
