hmmmm..... :hmm:
Just to throw a monkey wrench into this whole thing, does the battery meter on a sub measure current or voltage? I would imagine that it would measure voltage, otherwise you would have a constant drain on the battery(a current meter has to have current run thru it to measure it). If it IS a voltage meter, the current capcity of the battery would have very little effect on it, except in extreme conditions, i.e. extreme cold, extreme old age for the battery, etc, so you would have hit 100% voltage, even before you reached 100% current capacity(like 90-95%).
I think I just confused myself.....
