LiFePO4 batteries, or Lithium Iron Phosphate batteries, are a popular type of rechargeable battery used in a variety of applications, including electric vehicles, solar power systems, and portable electronics. While they are known for their high energy density, long cycle life, and low self-discharge rate, they can still encounter problems. In this guide, we will discuss some of the most common issues with LiFePO4 batteries and how to address them.
This can be caused by a number of factors, including age, over-discharging, or high temperatures. To troubleshoot this issue, try the following:
1. Ensure that the battery is not being charged and used as the same time.
2. Over-discharging the battery can cause it to lose capacity over time. Ensure that you are not using the battery below its recommended discharge level.
3. Check its age. LiFePO4 batteries have a limited lifespan, and they may lose capacity as they age. If your battery is several years old, then it is considered normal.
4. Check the charging process: Ensure that you are using a compatible charger and that the battery is not being overcharged. Overcharging can cause the battery to heat up and damage the cells.
5. Check the temperature: LiFePO4 batteries can be sensitive to high temperatures, which can cause the battery to discharge quickly. Ensure that the battery is not exposed to high temperatures, especially during charging.
To troubleshoot this issue, try the following:
1. It is recommended to use a dedicated LiFePO4 battery charger according to the rated charging current. Then have your battery go on a full charge. If it does not solve the problem, contact our customer service center for additional support.
2. If the voltage of your LiFePO4 battery is below 8V after it is fully discharged, BMS may be activated, or a short-circuit is likely.
One of the most common issues with LiFePO4 batteries is that they may not accept charge. This can be caused by a number of factors, such as a faulty charger, BMS activation or a defective battery. If your LiFePO4 battery is not charging, try the following troubleshooting steps:
(1) If its voltage is 10V~14.6V, your LiFePO4 battery might have gone bad. Please contact our technical support team and they will guide you through the process of providing a more detailed description of the issue.
(2) If its voltage is below 10V, the BMS maybe activated. Please check whether the charger matches your LiFePO4 battery, or whether its output is normal? And it is advisable to change a charger or solar controller to re-charge your LiFePO4 battery.
It’s normal, the voltage of your LiFePO4 battery will be 14.6V when it is fully charged, and it will drop to 13.3V after a night. Please note that voltage above 13V means your LiFePO4 battery is fully charged.
ATEM POWER’s LiFePO4 batteries can be connected in series or parallel, with up to two batteries being connected in each configuration. However, it is imperative that the batteries being connected have the same capacity, state of charge, and are of the same brand to prevent potential damage and ensure optimal performance. It is strongly advised not to connect ATEM POWER's LiFePO4 batteries with different brands together.
In conclusion, LiFePO4 batteries are a popular choice for various applications due to their high energy density, long lifespan, and reliability. However, like any other technology, LiFePO4 batteries may experience issues that require troubleshooting. By following the steps outlined above, you can identify and resolve some of the most common issues that may arise with LiFePO4 batteries.
