To create a 12V lithium battery pack, you need four lithium cells connected in series. Each cell typically has a nominal voltage of 3.2V to 3.7V. This configuration allows the pack to deliver the required voltage for various applications, such as electric vehicles and solar energy systems.
Understanding Lithium Cell Voltage
Lithium cells, particularly those using the LiFePO4 (Lithium Iron Phosphate) chemistry, have a nominal voltage of about 3.2V. When fully charged, these cells can reach approximately 3.6V to 3.7V. By connecting four cells in series, you achieve:
- 4 x 3.2V = 12.8V (nominal)
- 4 x 3.7V = 14.8V (fully charged)
This configuration is ideal for applications requiring a stable 12V output.
Battery Configuration Chart
| Number of Cells | Nominal Voltage (V) | Fully Charged Voltage (V) |
|---|---|---|
| 4 | 12.8 | 14.8 |
| 6 | 18.9 | 22.2 |
| 8 | 25.6 | 29.6 |
