BATTERY – 12.8V 200AH LIFEPO4 (4S/2P)

Description

BATTERY – 12.8V 200AH LIFEPO4 (4S/2P) refers to a lithium iron phosphate (LiFePO4) battery pack configuration. Let’s break down what each part of this specification means:

1. Voltage (V): This battery pack has a nominal voltage of 12.8 volts. This is the average voltage of the battery during discharge. When fully charged, a LiFePO4 cell has a voltage of about 3.2 volts, and it decreases gradually as it discharges.
2. Capacity (AH): The capacity of this battery pack is 200 ampere-hours (AH). This means the battery can provide a current of 200 amperes for one hour, 100 amperes for two hours, and so on. It’s a measure of how much energy the battery can store and deliver over time.
3. LiFePO4: This indicates that the battery chemistry is lithium iron phosphate. LiFePO4 batteries are known for their high energy density, long cycle life, and excellent thermal stability. They are commonly used in applications where a high energy density and long service life are required.
4. (4S/2P): This notation refers to how the individual LiFePO4 cells are connected within the battery pack.
   • 4S means that there are four LiFePO4 cells connected in series. This series connection adds up the individual voltages of each cell. In this case, each cell is likely 3.2 volts (as LiFePO4 cells are commonly 3.2V each), giving a total of 12.8 volts for the pack.
   • 2P means that there are two sets of these 4-cell series connected in parallel. This parallel connection increases the overall capacity of the pack without changing the voltage. Essentially, it doubles the capacity while keeping the voltage the same.
   • So, you have a battery pack with a total of 8 LiFePO4 cells, arranged in two parallel sets of four cells connected in series.

This type of battery configuration is commonly used in various applications, including solar energy storage, electric vehicles, and other systems that require a high-capacity and high-voltage battery pack. It’s important to note that while LiFePO4 batteries are known for their safety and long cycle life
