Or am I talking a load of rubbish?

We are basically talking the same thing, just using different numbers and words to describe it.
I got my numbers by dividing 72V by (1.4V per battery) to equal 51.4 batteries, then just rounded up. This I assumed would be wired in series to equal about 72V @ 2.7A.
Then each 'string' as I called them (I may be using the wrong term here) would be wired in parallel which would add the current to get your 100A.
To find this I took 100A and divided (2.7A per string of batteries wired in series) to equal 37.03 which I rounded to 37. (Cause rounding up to 38 would add another series of 52 batteries)
The end result is still 72V (ish) at 100A (ish) not taking into account wiring resistance, heat build up, improper matched cells, etc.
