(2020) emphasizes that charging should occur at a constant current followed by a constant voltage (CC-CV) method, which maximizes battery lifespan. Avoid overcharging, as it can lead to reduced capacity and safety risks. Aim to keep the battery’s State of Charge (SoC) between 20% and 80% for longevity.

Regular monitoring: Check the battery’s voltage regularly. A fully charged LiFePO4 battery should show 3.6 to 3.65 volts per cell. Monitoring helps to prevent excessive discharge and ensures cells remain balanced. Implement a Battery Management System (BMS) for real-time data analysis. A BMS can protect against over-current, over-voltage, and over-temperature conditions.

Appropriate storage conditions: Store the battery in a cool, dry environment. The ideal temperature range is between 32°F and 77°F (0°C to 25°C). Storing at extremes can degrade the battery chemistry. For long-term storage, charge to about 50% SoC to reduce the risk of self-discharge while preventing deep cycling, which might harm capacity.

Temperature management: Avoid exposing the battery to high temperatures above 140°F (60°C) and low temperatures below 32°F (0°C). High temperatures accelerate chemical reactions inside the battery, leading to thermal runaway or capacity loss, as noted in a study by Fang et al. (2019). Similarly, low temperatures can limit usable capacity and may freeze battery cells, causing permanent damage.

By adhering to these maintenance practices, you can extend the lifespan and enhance the performance of your 50Ah LiFePO4 battery.
