[Electric Boats] Battery charging time

 

If I had a 48 volt system with 4 12 volt 100 amp hour batteries how fast could they be charged. If I had a 10 kw generator how much would be wasted. What I am wondering is if one of the Honda 1000 gen sets is more than adequate? --- On Fri, 7/9/10, hardy71uk <p0054107@brookes.ac.uk> wrote: From: hardy71uk <p0054107@brookes.ac.uk> Subject: [Electric Boats] Re: Anyone have experience with 144 volt motor systems?

Best practice might be to charge from shore power and run the motor some of the time from the generator to conserve the battery power. DC motors can be run from an ac supply via a simple rectifier.
