I dont see how 2 cells vs 1 cell would serve you any better. .
Because on a single cell unit if a cell craps out you may be dead before you realise if your not checking often enough (who wants to spend a dive flushing to test cells

)
on a two cell system a 2nd cell may give you a warning (by showing a variance) that the other cell is duff PROVIDED the 2nd cell doesnt have the same fault - so it got to be a different age, maybe even different mnf.) if it does have the same fault your probably dead.
IMO 1 is stupid, 2 is unwise, 3 is a good start and 4000 cells of different ages and different suppliers would be quite safe.
the more cells you have the safer you will be - and the fewer the less safe - sure you can put protocals in place to manage only having 1 or 2 cells but at the end of the day you wont change that basic fact.
