Re: [Electric Boats] Proper battery capacity

 

How about 20kwh/ton? I have an 800 lb rig with 10kwh of lithium and "it gets worked."

We have a nice rule of thumb for power, about 1kw per ton of displacement.
I'd like to propose a battery standard.
How does 1wH per pound of displacement work?
Our test boat, a 7000lb Ericson 27 has 9600wH, and is never worked. A 13000lb Rawson 30 I converted has 12kwH of power, and it gets worked.
Other Systems..?
