36V LiFePO4 batteries have a higher energy density compared to lead-acid batteries—typically around 150-200 Wh/kg versus lead-acid’s approximately 30-50 Wh/kg. This allows them to store more energy in a smaller footprint.

As technology advances, battery chemistries continue to evolve, providing better solutions for energy storage across a wide range of applications. 36V LiFePO4 batteries, based on lithium iron phosphate (LiFePO4) chemistry, have gained popularity for their safety, durability, and reliability. However, when it comes to energy density, how do they compare to other battery types?

Higher Energy Density Compared to Lead-Acid Batteries

When comparing 36V LiFePO4 batteries to traditional lead-acid batteries, one of the most noticeable advantages is their higher energy density. Energy density refers to the amount of energy stored in a battery relative to its weight or volume. In this regard, LiFePO4 batteries significantly outperform lead-acid batteries.

For example, a 36V 12Ah LiFePO4 battery typically weighs around 4.5 kg, while a comparable lead-acid battery of the same voltage and capacity can weigh nearly three times as much. This substantial difference in weight and compactness makes LiFePO4 batteries a far more efficient choice for applications where portability and space-saving are essential, such as in electric bikes, scooters, and marine vessels.

The compact nature of LiFePO4 batteries also makes them easier to install and maintain, reducing both operational costs and installation time.

Moderate Energy Density Among Lithium-Ion Batteries

While LiFePO4 batteries boast a higher energy density than lead-acid alternatives, they fall behind when compared to other lithium-ion chemistries, such as lithium-ion (Li-ion) and lithium polymer (Li-Po) batteries. This difference is largely due to the specific capacity of the LiFePO4 cathode material, which is lower than the nickel-cobalt-aluminum (NCA) or nickel-manganese-cobalt (NMC) used in other lithium-based batteries.

For instance, LiFePO4 batteries typically offer an energy density of around 90-110 Wh/kg, whereas Li-ion batteries can reach up to 150-200 Wh/kg. Despite this lower figure, LiFePO4 chemistry is often chosen for its superior safety and longer cycle life rather than just focusing on energy density alone.

The Tradeoff Between Energy Density and Safety

One of the most significant considerations when selecting a battery type is the balance between energy density and safety. LiFePO4 batteries offer a safer and more stable option compared to other lithium-ion chemistries.

While the energy density of LiFePO4 is lower than that of NMC or NCA chemistries, the tradeoff comes in the form of improved thermal stability. LiFePO4 batteries are far less prone to thermal runaway, the process that can lead to overheating, fires, or even explosions in less stable chemistries. As a result, LiFePO4 batteries are preferred for applications where safety is paramount, such as in electric vehicles, solar energy systems, and backup power supplies.

For industries like transportation, where the risk of battery fires can have catastrophic consequences, the stability of LiFePO4 chemistry outweighs the slight reduction in energy density.

Longer Cycle Life

LiFePO4 batteries may not hold the highest energy density among lithium-ion options, but their cycle life far surpasses many of their competitors. A 36V LiFePO4 battery can typically last for more than 5,000 cycles, compared to the 500-1,000 cycles offered by many other lithium-based chemistries. This long lifespan makes LiFePO4 batteries a more cost-effective solution in the long run, as they require less frequent replacement.

This is especially important in applications where the battery is subjected to frequent charge and discharge cycles, such as in off-grid solar systems or commercial energy storage solutions. In these scenarios, the long cycle life compensates for the slightly lower energy density, offering better value over the battery’s entire lifespan.

Performance in High-Temperature Environments

Another area where 36V LiFePO4 batteries excel is in high-temperature environments. LiFePO4 chemistry is notably resistant to temperature fluctuations, which can degrade the performance and safety of other lithium-ion batteries. In contrast, LiFePO4 batteries maintain their performance in extreme temperatures, whether they are used in desert solar installations or in hot climates where other batteries might fail.

This thermal resistance also means that LiFePO4 batteries require less active cooling, further enhancing their reliability and reducing the costs associated with thermal management.

A common configuration in such battery systems involves arranging multiple cells in series and parallel to achieve the desired voltage and capacity.

Let’s dive deeper into the typical configurations, such as 12s1p, 12s2p, and 12s3p, and explore how they work in the context of 36V LiFePO4 batteries.

Understanding the Basics: Series and Parallel Connections

Each LiFePO4 cell has a nominal voltage of approximately 3.2V. In order to reach a total voltage of 36V, these cells are connected in series. When cells are connected in series (denoted by the “s” in configurations), the voltage adds up, but the overall capacity (measured in amp hours, or Ah) remains the same as a single cell. To increase the capacity while maintaining the same voltage, cells are also connected in parallel (denoted by the “p” in configurations). Let’s take a look at how this works.

12s1p Configuration

In a 12s1p configuration, 12 cells are connected in series. This means that the voltage of each cell (3.2V) is added together to achieve a total voltage of 38.4V when fully charged. This is the nominal voltage required for a 36V battery system, which typically operates within a voltage range of 36V to 42V. In this configuration, there is only one parallel group, so the capacity of the system is equivalent to the capacity of a single cell. For example, if each cell has a capacity of 100Ah, the total capacity of the battery remains 100Ah.

• Total Voltage: 38.4V (nominal)
• Total Capacity: 100Ah (assuming each cell is 100Ah)
• Application: Suitable for applications that require standard 36V power with no need for increased capacity.

12s2p Configuration

A 12s2p configuration involves 12 cells connected in series, but with two parallel groups. This setup effectively doubles the overall capacity while maintaining the same voltage of 36V. By adding cells in parallel, the current-carrying capacity increases, making the battery last longer between charges. If each cell has a capacity of 100Ah, the total capacity of the battery in this configuration becomes 200Ah.

• Total Voltage: 38.4V (nominal)
• Total Capacity: 200Ah (assuming each cell is 100Ah)
• Application: Ideal for higher-capacity applications, such as electric vehicles or golf carts that require extended runtime without increasing the overall voltage.

12s3p Configuration

In the 12s3p configuration, 12 cells are connected in series with three parallel groups. This setup further increases the capacity of the battery while maintaining the nominal voltage of 36V. With this configuration, the capacity triples, so if each cell has a capacity of 100Ah, the total capacity of the battery becomes 300Ah.

• Total Voltage: 38.4V (nominal)
• Total Capacity: 300Ah (assuming each cell is 100Ah)
• Application: Best suited for applications that demand even greater power capacity, such as solar energy storage systems, electric boats, and RV power supplies, where prolonged energy supply is crucial.

Why the 12s Configuration is Key for 36V Systems

The reason for using 12 cells in series (denoted as 12s) in a 36V LiFePO4 battery is based on the voltage requirements. Each LiFePO4 cell has a nominal voltage of 3.2V, and multiplying this by 12 gives you a total of 38.4V. This value is close to the fully charged voltage of 42V, which is typical for a 36V system.

The configuration allows the battery to operate within the voltage range needed for 36V devices, which often includes applications like electric bicycles, golf carts, and marine vehicles. At the same time, the use of parallel connections helps customize the capacity to fit the specific energy requirements of different devices.

Advantages of Configuring Cells in Parallel

When we configure cells in parallel (e.g., 12s2p or 12s3p), we significantly increase the battery’s capacity. Parallel connections allow the system to distribute the load across more cells, reducing the strain on each individual cell and leading to improved battery longevity. This method also increases the overall current output, enabling the battery to power larger or more demanding devices.

Parallel configurations are particularly useful in applications requiring higher energy storage, such as solar energy storage systems, UPS systems, and electric vehicles. In these scenarios, having a higher capacity battery ensures that the energy supply remains consistent, even during long periods of use.
