The constant voltage (CV) threshold for lithium batteries is typically 4.1v to 4.5v per cell. The charging IC monitors the battery voltage during constant current charging. Once the battery reaches the constant voltage charging threshold, the charger IC transitions from constant-current to constant-voltage regulation.

The electrical driving force across the terminals of a cell is known as the terminal voltage (difference) and is measured in volts. When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf.
