What is the Typical Voltage Range for a LiFePO4 Battery Used in Marine Applications?
The typical nominal voltage for a LiFePO4 (Lithium Iron Phosphate) battery is 3.2V per cell, with a fully charged voltage reaching up to 3.6V. In marine applications, these batteries are often configured in series to achieve higher voltages, such as 12V or 24V systems, making them suitable for various onboard electrical systems.
What is the nominal voltage of a LiFePO4 battery?
The nominal voltage of a LiFePO4 battery is approximately 3.2V per cell. This value represents the average voltage during discharge. When fully charged, the voltage can rise to about 3.6V. This nominal value is essential for determining how many cells are needed to create battery packs that meet specific voltage requirements for applications like marine systems.Nominal Voltage Overview Chart:
| Battery Type | Nominal Voltage | Fully Charged Voltage |
|---|---|---|
| LiFePO4 | 3.2V | 3.6V |
| Lithium-ion (NMC/NCA) | 3.6V | 4.2V |
| Lead Acid | 2.0V | 2.45V |
How does the voltage of LiFePO4 batteries compare to other lithium batteries?
When compared to other lithium-ion chemistries, LiFePO4 batteries have a lower nominal voltage:
- Lithium Nickel Manganese Cobalt (NMC) and Lithium Cobalt Oxide (NCA) batteries typically have a nominal voltage of around 3.6V, which allows them to store more energy per cell compared to LFP.
- The lower nominal voltage of LFP means that more cells are required in series to achieve higher voltages suitable for applications such as electric vehicles or marine systems.
