Well, if the six batteries are wired in series to get 48 volts, the
capacity of the six is essentially the capacity of the smallest-capacity
battery of the lot. As the smallest-capacity battery discharges, its
internal resistance increases, which prevents the discharge through it
of the batteries with greater capacity. If the six are identical,
however, then the capacity in amp-hours of the six in series is the same
as the capacity of any one of them alone. Only the voltage changes.

Or is that more confusing?

Now,, if he had 6 batteries and each one is an 8 volt .. does this
mean he has 8x6 = 48 volts of possible power? And how does this work
out to amps. ?


For the six batteries you mention to give 48 volts they would have to be
wired in series, i.e. each one positive to negative, whereas in parallel
(positive to positive and negative to negative) they would give you 12
volts, but the capacity would be the sum of the six batterys' capacities.


The OP's suggested 8 volt batteries - if he connects them in parallel,
they'll still give him 8 volts.
