Difference in battery technology between Lead-Acid chemistry (PbA) and Lithium-Iron-Phos

When attempting to compare LiFePO4 to PbA chemistries, the first major advantage of LiFePO4 cells are their ability to discharge power in terms of voltage (volts) and current (amps) over time (hours or seconds).   LiFePO4 chemistry has far greater power discharge capability than PbA chemistry because electricity is generated more efficiently from the movement of ions rather than from a chemical reaction and transformation.
