Quick Answer
Flooded batteries tend to have higher discharge rates compared to LiFePO4 batteries, especially in high-drain applications, but their overall lifespan is typically shorter due to factors like water loss and sulfation.
Discharge Rate Comparison
The discharge rate of flooded batteries is generally higher than LiFePO4 batteries due to their lower internal resistance and ability to deliver high current. For example, a 12V 200Ah flooded battery may have a maximum discharge current of 1000A, while a 12V 200Ah LiFePO4 battery might have a maximum discharge current of around 500A.
Cycle Life Comparison
LiFePO4 batteries typically have a longer cycle life compared to flooded batteries. According to industry standards, a LiFePO4 battery can achieve up to 3000 charge/discharge cycles before its capacity drops to 80% of its initial value. In contrast, a flooded battery may only achieve around 200-300 cycles before its capacity drops to 80%. This is due to the LiFePO4 chemistry’s ability to withstand degradation caused by repeated charge/discharge cycles and temperature fluctuations.
