Re: [Electric Boats] Electric Yacht system

Don,

I am just beginning my project, my first post here was just a few weeks ago, right about the time that I started doing my research into the feasibility of going electric with this boat. I'm still working on getting the old Yanmar SVE12 out of "Serenity".

Your 48v lithium for $600 may or may not be a bargain, it depends on the AH capacity. I know that EV components http://www.evcomponents.com/ sells a 48v 20AH battery with a built in battery management system (BMS) for about $770 (US residents have a 10% surcharge to cover ocean shipping and duties). you would need 4 of them to get to the same storage as your 4 group 27 wet cells.

I'm going to have similar kinds of problems with prop size, though with a full keel and the prop in an aperture, I may be more limited than you are. This configuration does simplify my system, because regen has little chance of working, so I can skip that part of the drive system.

Fair winds,
Eric
