Quick Answer
LiFePO4 cells in high-drain applications are generally effective, but their performance can be compromised if not properly chosen or configured.
Choosing the Right LiFePO4 Cells for High-Drain Applications
When selecting LiFePO4 cells for high-drain applications, it’s essential to focus on cells with high discharge rates and low internal resistance. Look for cells that can handle at least 10C of discharge (e.g., 1C for a 10Ah cell), and ideally those with an internal resistance of 10mΩ or lower. Some popular options include LG Chem, Sony, and Panasonic cells, which are known for their high discharge rates and reliability.
Configuring LiFePO4 Cells for High-Drain Applications
To get the most out of LiFePO4 cells in high-drain applications, it’s crucial to configure them correctly. This includes using a BMS (Battery Management System) that can handle the high discharge rates, as well as configuring the cells in a series and parallel configuration that balances the current and voltage requirements. For example, a 12V, 100Ah system might consist of 12 cells in series (4V each) and 5 cells in parallel, providing a total capacity of 100Ah and a maximum discharge current of 10A.
