Lithium-ion batteries explained

A Li-ion battery (a set of Li-ion cells in series) is charged in three stages: Constant Current, Balance (not required once a battery is balanced) and Constant Voltage. During the constant current phase, the charger applies a constant current to the battery at a steadily increasing voltage, until the voltage limit per cell is reached.
