When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack''s voltage rises.

The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.
The discharge voltage is the voltage level at which the cell operates while providing power. For li-ion cells, the typical voltage range during discharge is from 3.0 to 4.2 volts. It’s crucial to avoid letting the voltage drop below 3.0 volts, as over-discharging can lead to irreversible damage and significantly reduce the battery’s capacity.
When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises.
Rechargeable lithium batteries are commonly referred to as “lithium-ion” batteries. Single lithium-ion batteries (also referred to as cells) have an operating voltage (V) that ranges from 3.6–4.2V. Lithium ions move from the anode to the cathode during discharge. The ions reverse direction during charging.
