Why 3.85V Equals 4.45V, 3.8V Equals 4.35V, and 3.95V Equals 4.50V for LiPol Batteries
The voltage values you’re referring to — 3.85V equals 4.45V, 3.8V equals 4.35V, and 3.95V equals 4.50V — are comparing the nominal voltage of LiPol Batteries (Lithium Polymer or Li-ion) with their full charge voltages.
1. Nominal Voltage vs. Full Charge Voltage in LiPol Batteries
- Nominal Voltage: This represents the average operating voltage of a LiPol Battery under normal conditions. For most Li-ion or LiPo cells, the nominal voltage is generally around 3.7V to 3.8V.
- Full Charge Voltage: This is the maximum voltage a LiPol Battery can reach when fully charged. Typically, the full charge voltage of a Li-ion or LiPo cell is 4.2V per cell.
2. Why the Difference?
The values you’re mentioning seem to refer to the comparison between the nominal voltage (e.g., 3.85V) and the full charge voltage (e.g., 4.45V) of LiPol Batteries. This is a typical behavior for Li-ion and LiPo batteries:
- A nominal voltage of 3.85V typically corresponds to a fully charged voltage of about 4.45V.
- A nominal voltage of 3.8V corresponds to a fully charged voltage of around 4.35V.
- A nominal voltage of 3.95V corresponds to a fully charged voltage of around 4.50V.
This difference exists because LiPol Batteries can reach a higher voltage when fully charged (usually around 4.2V or slightly higher), and as the battery discharges, the voltage gradually drops to the nominal voltage.
3. Battery Chemistry Considerations
- LiPol Batteries (like Li-ion and LiPo batteries) have a voltage range that varies depending on the state of charge.
- Nominal voltage is generally considered the middle point of the battery’s discharge cycle, while the full charge voltage is at the higher end of the voltage range.
- LiPol Batteries typically have a maximum voltage of 4.35V to 4.45V per cell when fully charged, with nominal voltages around 3.7V to 3.8V.
Conclusion:
- The 3.85V, 3.8V, and 3.95V values represent the nominal voltages of the LiPol Battery, while the 4.45V, 4.35V, and 4.50V values are their corresponding fully charged voltages. These voltages reflect the typical behavior of LiPol Batteries during use and charge cycles, and understanding this distinction can help in managing battery performance effectively.
