The maximum capacity of a LiFePO4 (Lithium Iron Phosphate) battery can vary widely based on its design and intended application. Generally, these batteries can reach capacities from 12Ah to several hundred Ah, with some specialized configurations exceeding 1000Ah. For instance, a 12V 400Ah LiFePO4 battery can be expanded to a maximum capacity of 1600Ah when connected in series and parallel configurations.
Factors Influencing Capacity
1. Configuration
LiFePO4 batteries can be connected in various configurations to increase their total capacity:
- Series Connection: Increases voltage while maintaining the same capacity.
- Parallel Connection: Increases capacity while maintaining the same voltage.
For example, a 12V 400Ah battery can be configured in a 4S4P setup to achieve a total capacity of 1600Ah at 51.2V.
2. Cell Size
The physical size of the cells used in the battery also impacts capacity. Larger cells, such as those in the 26650 or 32650 formats, can provide higher capacities compared to smaller cells like the 18650, which typically have capacities ranging from 2200mAh to 3500mAh.
Typical Capacities in Common Applications
| Application | Typical Capacity Range |
|---|---|
| Electric Vehicles (EVs) | 40Ah to 1000Ah |
| Solar Energy Storage | 100Ah to 400Ah |
| RV and Marine Applications | 100Ah to 300Ah |
| Power Tools | 2Ah to 20Ah |
