How Temperature Affect Lipo Battery?


LiPo (Lithium Polymer) batteries have gained widespread use in various industries, powering devices ranging from smartphones and drones to electric vehicles. Temperature is one of the biggest threats to lipo battery performance and durability. Even if a lipo battery is designed to last for 5 years, it may fail within a year if not stored or used within the recommended temperature range.Understanding how external factors, such as temperature, affect LiPo battery life is crucial for optimizing their performance and ensuring longevity. This article delves into the effects of low temperature on LiPo battery life, exploring scientific methods employed to study this phenomenon and suggesting mitigation strategies. At first, we will discuss how lipo batteries perform in both hot and cold temperatures. Keep reading to learn more.

Will Lipo Battery Work Better in Hot or Cold?

When using a lipo battery, it is always better to ensure the temperature is right. We have heard stories of lithium batteries that exploded because they were left charging under too much heat. Other users have been forced to buy new batteries because they left their lipo batteries in the heat for too long.

That leaves many wondering whether lipo batteries work well in hot or cold temperatures. The simplest answer is neither. Lipo batteries require optimum temperatures to work effectively. That is why a lipo battery will last the longest if you keep it at room temperature for a long time.

How lipo batteries work?

To understand this, we need to go back to the basics and look at how batteries work. Science is deep and complex, but we can always simplify it.

A battery has an electrolyte, through which positively and negatively charged electrons travel to the electrodes. Chemical reactions take place during charging and during discharging.

Like any chemical reaction, heat is produced when batteries are active. It’s not too hot for you to feel, but it creates the right environment for proper reaction and energy production.

Cold and hot temperature?

LiPo (Lithium Polymer) batteries are sensitive to extreme temperatures, and neither excessively hot nor cold environments are ideal for their performance and lifespan. However, if we compare the two extremes, LiPo batteries generally fare better in moderate cold temperatures than in extreme heat. Let’s explore the effects of hot and cold temperatures on LiPo battery performance.

Since there is always heat with the battery, the last thing you want is more heat. Hot temperature increases the chemical reactions which puts too much strain on the battery. As a result, the lipo battery drains much faster, affecting its capacity in the end.

When you feel that your battery is too hot, remove it and put it in a cool dry place until it is cold again?Leaving it under the stress of too much heat can lead to swell. Why?

High temperature

Exposing LiPo batteries to high temperatures can cause a temporary reduction in capacity. Heat accelerates the chemical reactions within the battery, leading to increased self-discharge and energy loss over time. High temperatures increase the internal resistance of LiPo batteries. This elevated resistance hinders the efficient delivery of power, resulting in voltage drops and diminished performance. High internal resistance can also lead to excessive heat generation and potential safety hazards.Prolonged exposure to high temperatures can shorten the overall cycle life of LiPo batteries. The accelerated chemical reactions at elevated temperatures cause faster degradation of the battery’s components, leading to a decrease in its ability to hold a charge effectively. Extreme heat can potentially trigger a dangerous condition called thermal runaway. In this situation, the battery temperature rapidly increases, leading to a chain reaction of heat generation that can culminate in a fire or explosion. It is crucial to avoid subjecting LiPo batteries to excessive heat to prevent this safety risk.

Low temperature

Like in hot temperatures, LiPo batteries may experience a temporary reduction in capacity when exposed to extreme cold. The chemical reactions slow down at low temperatures, limiting the battery’s discharge efficiency and available energy. However, this capacity loss is often reversible once the temperature rises. Cold temperatures can increase the internal resistance of LiPo batteries. High resistance impedes power delivery and can result in voltage drops and reduced performance, especially in applications that require high current output. In very cold conditions, LiPo batteries may struggle to deliver power at high discharge rates. The freezing of electrolytes and limited mobility of ions within the battery cells can restrict the battery’s ability to release energy rapidly.

Exposing LiPo batteries to extremely low temperatures for extended periods can cause permanent damage. Freezing of the electrolyte or prolonged exposure to sub-zero temperatures can result in cell expansion, internal short circuits, or damage to the battery casing.

As you can see, a lipo battery will not work well in either hot or cold conditions. Neither extremely hot nor cold temperatures are optimal for LiPo battery performance and lifespan. While both temperature extremes can negatively impact LiPo batteries, excessive heat tends to be more detrimental. High temperatures accelerate capacity loss, increase internal resistance, and can lead to thermal runaway. Cold temperatures can temporarily reduce capacity and increase internal resistance, but these effects are often reversible once the temperature rises. Implementing temperature regulation, insulation, gradual adaptation, and proper storage practices can help optimize LiPo battery performance and extend their lifespan in both hot and cold conditions. However, most people prefer the cold because it reduces the chemical reaction, which can give your lipo battery more life.

Test Methods about Temerature Affecting Lipo Battery

Researchers have utilized different methodologies to examine the impact of low temperature on LiPo battery life. These methods, including controlled laboratory experiments and real-world testing, provide valuable insights into understanding the behavior of LiPo batteries in cold environments.

  1. Controlled laboratory experiments: In controlled laboratory experiments, LiPo batteries are subjected to various low-temperature conditions within environmental chambers. Researchers carefully monitor critical parameters, such as battery capacity, internal resistance, voltage profiles, and charge acceptance rates, under controlled temperature settings.
  2. Real-world testing scenarios: Real-world testing involves monitoring LiPo battery performance in actual operating conditions during cold weather. Data is collected from devices or systems that utilize LiPo batteries, such as drones or electric vehicles, in cold environments. Researchers measure the battery’s state of charge, discharge characteristics, and temperature variation to assess the effects of low temperature on battery life.


In conclusion, temperature has a significant impact on LiPo (Lithium Polymer) battery performance and lifespan. Both high and low temperatures can affect the battery’s capacity, internal resistance, discharge rates, and overall longevity.

Exposing LiPo batteries to excessive heat can lead to capacity loss, increased internal resistance, and a reduced cycle life. The chemical reactions within the battery accelerate, resulting in faster degradation of its components. Moreover, extreme heat poses the risk of thermal runaway, which can lead to fire or explosion.

Similarly, extremely cold temperatures can cause temporary capacity loss, increased internal resistance, and reduced discharge rates. LiPo batteries may struggle to deliver power efficiently in very cold conditions, limiting their performance. Prolonged exposure to sub-zero temperatures can also result in permanent damage to the battery.

To optimize LiPo battery performance, it is essential to regulate the operating temperature within the manufacturer’s recommended range. Insulation, gradual temperature adaptation, and proper storage practices can help mitigate the harmful effects of temperature extremes. By taking these precautions, users can ensure that their LiPo batteries perform optimally and have an extended lifespan.
