What should we take care of when choosing a LiFePO4 battery? What are the important parameters of a LiFePO4 battery? How to choose the right battery? This article delves into the crucial parameters and features that set LiFePO4 batteries apart, including new sections on battery storage, charge and discharge currents, cycle life, warranty, and extra functions.


LiFePO4 Battery Storage

Proper storage of LiFePO4 batteries is essential to maintain their lifespan and performance. Ideal storage conditions involve keeping them at a partial state of charge, typically around 50-60%, in a cool, dry environment to minimize degradation.


Battery Voltage

The nominal voltage of a single LiFePO4 battery is 3.2V, so the actual rated voltage of most 12V battery packs (including our 他一tykool batteries) is 12.8V. It is still compatible with most chargers, controllers, and inverters. Just need to know the voltage difference between 12V LiFePO4 and 12V lead-acid batteries to avoid the possibility of incompatibility with other components.


Cycle Life

A standout feature of LiFePO4 batteries is their impressive cycle life. These batteries can undergo thousands of charge-discharge cycles with minimal degradation. This extended cycle life not only underscores their durability but also enhances their cost-effectiveness over time, significantly reducing the total cost of ownership.


Voltage Stability

Voltage stability is another hallmark of LiFePO4 batteries, providing a consistent output throughout the discharge cycle. This stability is crucial for electronic devices and systems that require a steady power supply for optimal operation.


Self-Discharge Rate

LiFePO4 batteries boast a low self-discharge rate, meaning they retain their charge for longer periods when not in use. This property is particularly beneficial for seasonal applications where batteries may go extended periods without charging.


Operating Temperature Range

The operational temperature range of LiFePO4 batteries is broad, allowing them to perform reliably in both hot and cold environments. This versatility ensures consistent performance across diverse climatic conditions, further broadening their applicability.


Charging Rate

LiFePO4 batteries support fast charging, a critical parameter for many users. The ability to quickly recharge minimizes downtime and enhances usability, especially in applications like start-stop car where charging speed can influence practicality and convenience.


Safety Features

Safety is paramount in battery technology, and LiFePO4 batteries excel in this area. Their chemistry is inherently more stable and less prone to issues like thermal runaway, making them safer for use in a wide range of temperatures and conditions without the risk of combustion or leakage.


Max Charge and Discharge Currents

Understanding the maximum charge and discharge currents of LiFePO4 batteries is vital for system design and safety. These parameters ensure that the batteries are used within their capability range, preventing overheating and maximizing efficiency. It is recommended to charge at a current below 0.5C, and it is not recommended to charge at too high a current. Even if the BMS has temperature protection, excessive current can cause internal overheating of the battery.



For the lithium battery for ESS( energy storage) such as solar power, UPS and telecom, we can offer 5~10 years. As the use frequency of starting batteries is very high and the use environment is very special, our battery are consumables, so the warranty period is usually set as one year in our industry. For a reasonable risk assessment, we still recommend customers not provide too long warranty period, even if we are very confident about the quality of our products, however, many uncontrollable human factors are difficult to define is quality problem or not.



The Bluetooth function can allow users to have a better understanding of the internal condition of the battery, such as SOC, voltage, temperature, etc. You can also set parameters such as overcharge voltage and overcurrent.


Self Heating Function

For some customers in high latitude or cold regions, they will require the battery to develop a self heating function. This function allows the internal heating film to heat the inside of the battery below 0 ℃. Then you can charge the battery very well. However, in areas where the annual temperature is above 0 ℃, this function is not very necessary.


Extra Functions

Extra Functions are options depending on the user and can be added if necessary.



The parameters of LiFePO4 batteries, including their energy density, safety features, cycle life, and additional functionalities like those offered by Tykool batteries, make them a compelling choice for a wide array of applications. Whether for automotive, storage, or portable power needs, LiFePO4 batteries provide a reliable, efficient, and safe power solution. As the demand for sustainable and high-performing batteries continues to grow, understanding these key parameters will help buyers make informed decisions in selecting the right battery for their needs.
