Re: [electricboats] Throttle control head

Thanks all!  Some good solutions and good points there.  Great to see some of that up close.  Somewhat unrelated question (though they're all really related) regarding batteries.  My plan at the moment for this cat is a pair of ME1616s (as part of the Thunderstruck kits) which I plan to run at 48v.  I'm trying to decide how many amp hours of battery power I should shoot for.  I've looked at the spec sheets on the motor, but I'm not sure if I'm interpreting it correctly regarding power consumption.  I'd like to run a single battery pack (unless there are good reasons I shouldn't), which I'll also charge my house batteries with using an MPPT or DC to DC converter. 

My thought was 32 of the LF304 Eve cells.  So two parallel 48v, 304 ah banks, resulting in 608 ah bank to run both ME1616 motors.  Keeping in mind this is a sailboat and we very much intend to sail as much as possible, mostly long passages...is that 608 amp hours overkill?  Other than maneuvering, we'll probably spend most motoring time with just one motor.  We'll have about 2000 watts of solar as well, plus a 6kw generator.  Hoping for but not expecting a little regen while sailing as well as through the unused motor when motoring.  I realize "how much battery power do I need" is very subjective, but I welcome all opinions since I really just don't know.

Thanks again!
