Re: Battery capacity - Peukert stuff

"That's simply linear -- bigger bank, bigger time remaining."

True, but that's the it really linear if multiples of batteries are coupled. The P equation has five inputs as you know - the only one that could change if I enlarge the bank is the available amp hours. If I double up batteries to double the amp hours available I could just double the minutes available as computed from the single battery configuration; or, I could use the now doubled available amp hours in the P equation and I will see that the available minutes at any amperage more than doubles by something on the order of 10%. Which way is correct?
