The SER405080 Lipo battery gets its name from its approximate dimensions: 40mm in length, 50mm in width, and 80mm in height (the exact dimensions may vary slightly depending on the manufacturer's specifications). This relatively compact size makes it suitable for integration into various portable electronic devices where space is often at a premium. The lithium - polymer construction allows for a thin and flexible form factor compared to traditional cylindrical lithium - ion batteries, enabling designers to create more ergonomic and innovative product shapes.

Electrical Specifications

• Voltage: The battery operates at a nominal voltage of 3.7V. This is a standard voltage level for many single - cell LiPo batteries and is well - suited for powering low - to medium - power electronic devices such as smartphones, smartwatches, and portable gaming consoles. During charging, the voltage can rise to around 4.2V, and during discharge, it gradually decreases. It is important to note that operating the battery outside its specified voltage range can lead to performance degradation or even safety hazards.

• Capacity: With a capacity of 1850mAh (milliampere - hours), the SER405080 can store a significant amount of electrical energy. This capacity determines how long the battery can power a device before it needs to be recharged. For example, if a device consumes 100mA of current continuously, the battery can theoretically power it for approximately 18.5 hours (1850mAh / 100mA = 18.5h). However, actual usage times may vary depending on factors such as the device's power management efficiency, operating mode, and environmental conditions.

Energy Density

One of the key advantages of LiPo batteries is their high energy density. The SER405080 offers a relatively large amount of energy storage in a compact package, which is crucial for portable devices that require long - lasting power without adding excessive weight. This high energy density is achieved through the use of advanced lithium - polymer chemistry, which allows for a higher proportion of active materials in the battery cells compared to other battery types.

The Role of the Protection Circuit Module (PCM)

Overview of PCM

The PCM is an essential component integrated into the SER405080 battery. It serves as a safeguard to protect the battery from various potential issues that could arise during charging, discharging, and storage. The PCM consists of a set of electronic components, including integrated circuits, resistors, and capacitors, which work together to monitor and control the battery's operation.

Protection Functions

• Over - charging Protection: One of the primary functions of the PCM is to prevent over - charging of the battery. When the battery voltage reaches its maximum safe level (usually around 4.2V), the PCM automatically cuts off the charging current, preventing further voltage increase. Over - charging can cause the battery to overheat, swell, or even explode, so this protection is crucial for ensuring the safety and longevity of the battery.

• Over - discharging Protection: Similarly, the PCM protects the battery from over - discharging. When the battery voltage drops to a certain low level (typically around 2.7 - 3.0V), the PCM disconnects the load from the battery, preventing further discharge. Over - discharging can damage the battery's internal structure and reduce its capacity over time.

• Short - Circuit Protection: In the event of a short - circuit, where the positive and negative terminals of the battery are directly connected, the PCM quickly detects the excessive current flow and shuts down the battery to prevent overheating and potential fire hazards.

• Over - current Protection: The PCM also monitors the current flowing in and out of the battery. If the current exceeds a safe limit during charging or discharging, it will limit or cut off the current to protect the battery and the connected device.
