I know that   watts = amps * volts,  and watt-hours (wh) is a measure of
energy, but over and over again I hear people talking about EV batteries in
terms of amp-hours.  What does that mean if you don't know the voltage?
1000 amp-hr is not impressive if the voltage is, say, 0.00001 volts.  Is
there some sort of standard voltage, e.g., 3.6 volts, that is assumed when
one talks about LiON batteries?  Does amp-hours tell you something more
than watt-hours?

Thanks in advance,--
