None of the information you have helps with saying whether this relation
will still be valid above 93A, but perhaps it should be good up to the
rated maximum current of the batteries??

Caveat is that battery voltage drops at high current due to reversible
changes, so using an underlying open circuit fixed voltage for detecting
a given discharge point is too conservative. But, as I say, the makers
use a linear relation up to 93A so perhaps it is not outrageously wrong.
In any case, unless they tell you how you can't allow for this
accurately.
