The nominal voltage of lithium-ion cells is typically around 3.6V to 3.7V. This is the average voltage when the battery is in a stable state, neither charging nor discharging. State of Charge (SOC) is crucial for monitoring battery health. For best performance, lithium batteries should be within specific voltage ranges:
A lithium battery voltage chart is an essential tool for understanding the relationship between a battery’s charge level and its voltage. The chart displays the potential difference between the two poles of the battery, helping users determine the state of charge (SoC).
The lithium battery full charge voltage range is such that they are deemed wholly charged when the voltage hits about 4.2 V. Some batteries can reach 4.35V at full charge. It’s crucial to remember that going beyond this voltage might result in overcharging, which can be dangerous and shorten the battery’s life.
The chart displays the potential difference between the two poles of the battery, helping users determine the state of charge (SoC). For example, a fully charged lithium-ion cell typically has a voltage of 4.2V, while a discharged cell may have a voltage of 3.0V or lower.
A 12-volt lithium-ion battery that has been completely charged should show between 14.5 and 14.9 volts. The battery is completely charged and has achieved its maximum capacity when the voltage level reaches this level. When full charge, measured without disconnecting the charger, it is generally around 14.5 volts, up to 14.9 volts.
The common sense of lipo voltage as below: 1. A fully charged lipo voltage is 4.2V per cell (HV lipo can be charged to 4.35V). 2. A lipo cell battery should never be discharged below 3.0V. 3. The proper lipo storage voltage is 3.8V per cell. 4. A lipo cell nominal voltage is 3.7V.
