Re: difference between wound and permene
Donald...you have misunderstood what I was
saying. You are right on some points...the battery amp
hours dont change, HOWEVER, there ability to deliver

Re: AC Power Use
You got it Larry,<br>When you discharge your
batteries it's hopefully not to 100% DOD, but counting the
losses 240 ah is a good number to use. The rest is
correct and should work out to around a buck

Re: Great chat - whens the next one...
Corrosion resistance and resistance to
electrolysis can be designed into the system by electically
isolating the system. On PM DC motors the torque curve is
not a curve at all but instead they have a

Re: difference between wound and permene
Technically speaking.. PM DC magnet motors for 24
or 36 volts dont work either because of the current
required to make the torque. But then too,why would you
want to when higher voltage motors are so

Re: AC Power Use
Hi Larry,<br>I beleive the two numbers you have
to find are:<br>Charger efficiency (in %) and
Battery charge acceptance (in %). Normal numbers look
like 15~20% loss at the charger (Heat) and 25% +/-

Re: Great chat - whens the next one...
I believe that the speed limit you refer to is
based on mono hulls and also is limited to displacement
hulls. I agree that cats and even tri hull will have
high speeds. I don't think this area has

is to just set a data - see who shows up and discuss
