For battery packs, the voltage difference between individual cells is one of the main indicators of consistency. The smaller the voltage difference, the better the consistency of the cells and the better the discharge performance of the battery pack.
Therefore, you should pay attention to the brand from which you are purchasing your batteries. If there is a gap in the voltage of the battery pack, you can correct it with additional equipment, such as with a BMS, balance charging, etc. Stay tuned for Part 2 of voltage difference: How to prevent voltage difference.
In a series connection, the positive terminal of one cell is connected to the negative terminal of the next cell. This setup increases the overall voltage of the battery pack. For example, connecting three 3.7V cells in series results in a battery pack with a total voltage of 11.1V (3.7V x 3). 2. Parallel Connection
Part 2. What does the S on a lithium battery pack mean? The “S” in a lithium battery pack stands for “Series.” It indicates the number of cells connected in series. For instance, a 3S battery pack has three cells connected in series. If each cell is 3.7V, the total voltage of the pack is 11.1V (3.7V x 3).
Electric Vehicles (EVs): EVs use large battery packs. Let's say each cell has a nominal voltage of 3.7 volts (common for lithium-ion cells). If an EV requires a 400-volt battery pack, you would need about 112 cells in series (400 volts / 3.7 volts per cell). This series configuration increases the voltage to meet the vehicle's requirements.
For example, lithium-ion batteries (which are used in most modern smartphones and laptops) have a nominal voltage of 3.7V per cell, while alkaline batteries typically have 1.5V. Number of Cells: Most batteries, especially rechargeable ones, are composed of multiple cells connected in series. Each cell contributes to the overall voltage.
