Customized 12.8V 20ah 26650 Li-Ion Rechargeable Battery Pack

In power lithium batteries, "nominal voltage" and "capacity" are two key battery parameters that have a significant impact on battery performance and application. It is very important for the average user to understand what these two parameters mean and how they affect the performance of the battery. When selecting a battery product, there is often a trade-off between these two parameters to meet the specific application needs. Let's explore whether the higher the nominal voltage value or the larger the capacity value in the power lithium battery.

First, let's understand what these two parameters mean. "Nominal voltage" refers to the nominal voltage of the battery, which is the voltage value specified in the design of the battery. In power lithium batteries, usually the unit of nominal voltage is volts (V), and the nominal voltage of different types of lithium batteries will also be different, the common ones are 3.2V, 3.7V, 3.8V, etc. "capacity" refers to the capacity of the battery, which indicates the amount of charge that the battery can store, usually measured in ampere-hours (Ah) or milliampere-hours (mAh). The larger the capacity, the more power the battery stores and can support the device for a longer period of use.

Next, let's discuss whether it is better to have a larger nominal voltage or a larger capacity value in a power lithium battery.

For nominal voltage, a higher value usually means that the cell voltage of the battery is higher, which can improve the efficiency of the device to a certain extent. For example, in high-demand electric vehicles and energy storage systems, the use of high-voltage batteries can reduce current, reduce line thickness and material costs, and improve overall energy density and efficiency. In addition, the high-voltage battery is also conducive to reducing the number of connecting wires in the battery pack, simplifying the design structure of the battery pack, and reducing the complexity of the system.

In the case of capacity, a higher value means that the battery can store more power, which extends the life of the device. Especially in electric vehicles, ships or energy storage systems that require a long range of life, high-capacity batteries can provide longer range or energy storage time to meet users' needs for range.
