RE: [Electric Boats] Re: battery bank upgrade

 

DRMSUDO noted: Yes, I own a honda 2000. In my experience the generator is only good for charging. I have tried to use it to drive the dc motor and it is just not powerful enough…. 

 

The Honda EU2000i can continuously output up to 1.6kw.  With enough charger onboard, I’ve successfully delivered 1.44kw into my pack for 17hours while cruising against the current.  With a 48v pack as you have, this would be just about 30amps.  This could double your range at 5knots or allow you to cruise indefinitely at up to 4knots.  Attempting to draw any more than this power continuously will stop the generator, so you’d have to have a charger that is either adjustable or otherwise limited in the energy it draws.  So YES, while the generator is only good for charging, that you can deliver up to 30amps into your battery bank with it means that you can draw up to 30amps less from your pack if you ran your generator and a properly sized charger while in a pinch.
