What are LiFePO4 battery disadvantages?

Although LiFePO4 batteries offer many advantages, they also come with some disadvantages. For instance, the upfront cost is clearly higher compared to lead-acid or other lithium-ion alternatives. Additionally, the product range is more limited: not all power ratings, sizes, or shapes are widely available, which may require custom solutions in some cases.

LiFePO4 batteries also perform less effectively at very low temperatures, which can make them harder to use in cold environments. That said, the advantages of LiFePO4 technology should not be overlooked. These batteries require no maintenance, can be 100% deeply discharged, and offer up to five times more charge cycles than lead-acid batteries.
