Hi full_mosey,

To me 60% of the amp hours would be 60 amps on a 100 amp-hour battery. At 12.8 volts that works out to about 768 watts. I guess I don't follow the logic.

So 60 watts per 100 amp-hours, not 60% of the amp-hours.


Actually, that is 60% of battery AHs.

120/200=.6, 180/300=.6; all 60%.

.6 * 440 = 264, 264/440 = 60%, or 60W per 100 AHs.
