Ok golf cart deep cycle battery 220 A/hr X 6 (V) =1320W/hr
1320/67lb= 19.7 W/hr a little better than the average 18 I came up with but clearly in the same ballpark as starting batteries.
And again that is at 20 hour discharge rate! And I imagine peukert bites them the same way as any lead acid but could be wrong.
Imagine if battery technology could match the energy density of gasoline and we
had a 36Kw/hr battery that weighed 7 lb! (or what ever a gallon of gas is)
Then we could say ok I've got 10 of these in my EV that's the same as a 10 gallon gas tank in a ICE vehicle. And the EV would have a 1200 mile range!
Ok I'm just dreaming.
