LiFePO4 batteries exhibit a flat discharge curve. For most of the battery''s capacity, the voltage stays relatively constant. It is only at the extreme ends of the state of charge that the voltage changes drastically. This differs from lead acid batteries, where the voltage curve slopes steadily downward as the battery discharges.
