Re: [electricboats] Electric Motor for 40ft Sailboat

Ahh split supply!! Indeed a possibility but with great care fir charging and breakers. 96 will reduce current cobsiderably. Now you got me thinking.

Consider going with 96v. It's not that much more complicated than 48v but gives you twice the horsepower out of the motor when you need it. Most of the time you won't need more than 5kw. A +48/-48 bipolar isolated system (fuses/breakers & contactors on both rails with the safety ground between the two 48v series-connected banks) is also a possibility.
