To create a 48v battery using Tesla 2170 cells, connect 12 cells in series. Each cell provides about 4.8v. This setup achieves a total capacity of roughly 2500mAh. The 2170 cells have better energy density and efficiency compared to older cylindrical cell sizes. They play a vital role in electric vehicles, especially the Tesla Model 3.
By dividing 48V by the nominal voltage of a single cell, we find that approximately 13 cells in series (48V ÷ 3.7V ≈ 13 cells) are required. This arrangement allows the voltage to reach 48V while maintaining the necessary capacity based on the cells’ amp-hour ratings.
It is vital to consider the total capacity needed for the application. The capacity of the battery system can be adjusted by varying the number of parallel strings if higher power is required. Using 13 cells in series provides the desired voltage, but the overall design must accommodate the intended use case.
As we explore further, we will examine essential parameters such as capacity, discharge rates, and how to integrate these cells effectively in various custom applications.
How Is Voltage Calculated in Battery Systems?
Voltage in battery systems is calculated using the formula: Voltage (V) = Number of cells × Voltage per cell. To determine the voltage, follow these steps:
-
Identify the number of battery cells in the system. For example, a typical lithium-ion cell has a voltage of about 3.7 volts when fully charged.
-
Multiply the number of cells by the voltage of each cell. For instance, if you have 13 cells, the calculation would be 13 cells × 3.7 volts per cell = 48.1 volts total.
In summary, to calculate the total voltage in a battery system, multiply the number of cells by the voltage of each cell. This method ensures accurate voltage representation based on cell configuration.
How Does Voltage Depend on Battery Cell Configuration?
Voltage depends on battery cell configuration in a direct and predictable manner. Battery cells can be connected in series or parallel combinations. Each method affects the total voltage output.
When battery cells connect in series, their voltages add together. For example, if each cell provides 3.7 volts and you connect ten cells in series, the total voltage equals 37 volts. This demonstrates that the overall voltage increases with the number of cells in series.
Conversely, when cells connect in parallel, the total voltage remains the same as a single cell’s voltage. The combined capacity, or amp-hour rating, increases. If you connect three 3.7-volt batteries in parallel, the voltage stays at 3.7 volts. However, the total energy storage capacity triples.
To achieve a specific voltage such as 48 volts, you need to connect a sufficient number of cells in series. For instance, to reach 48 volts using 3.7-volt cells, you would need about 13 cells in series. The calculation is 48 volts divided by 3.7 volts per cell, which equals approximately 12.97. Round up to 13 cells to deliver the desired voltage.
In summary, the voltage output changes based on how you configure the battery cells. Series connections increase voltage, while parallel connections maintain the same voltage but increase capacity. Understanding these principles allows for effective battery design to meet voltage requirements.

What Is the Formula for Calculating 2170 Battery Cells in Series To Reach 48V?
To achieve 48V using 2170 battery cells in series, the formula is to divide the target voltage by the nominal voltage of one cell. A standard 2170 lithium-ion cell has a nominal voltage of 3.6V or 3.7V. For a 48V target, the calculation requires determining how many cells are needed: 48V ÷ 3.7V = approximately 13 cells.
The calculation aligns with the information provided by the Battery University, which explains that lithium-ion cells typically operate around 3.6 to 3.7 volts per cell. Therefore, to achieve a specific voltage in battery packs, one must consider the nominal voltage of the individual cells.
Connecting battery cells in series adds their voltages together. Thus, for a 48V system, you need either 13 cells (using 3.7V) or 14 cells (using 3.6V nominal voltage). This configuration balances the need for power while managing the size of the battery stack.
The U.S. Department of Energy emphasizes the importance of using properly configured battery packs to ensure efficiency and safety in energy storage systems. Using the correct number of cells is crucial for performance and longevity.
