The Molicel P28A 18650 battery is a high-performance lithium-ion cell designed for applications that demand reliable and sustained power. With a remarkable capacity of 2,800 mAh and a maximum continuous discharge rate of 35A, the P28A is engineered to provide impressive energy output in a compact form. This makes it a suitable choice for high-drain devices where power delivery is critical, such as power tools, electric vehicles, and high-performance flashlights. The combination of high capacity and high discharge rate sets the P28A apart as a versatile, high-capacity cell capable of handling demanding tasks without compromising performance.

At its core, the Molicel P28A is a 18650-size cell, with a standard diameter of 18.50mm and a length of 65.15mm, making it compatible with a wide range of devices that require 18650 batteries. This size allows the P28A to fit seamlessly into applications like flashlights, e-bikes, power tools, and other equipment that rely on reliable power sources. Despite its relatively compact size, the battery can deliver powerful output, which is a significant advantage in portable power applications where weight and size are important considerations.

The battery's nominal voltage of 3.6V is typical for lithium-ion cells, ensuring that it can deliver consistent performance across a wide range of devices. With a maximum voltage of 4.2V when fully charged and a cutoff voltage of 2.5V during discharge, the Molicel P28A operates within a voltage range that maximizes its efficiency and safety. These voltage parameters help ensure that the battery maintains a steady power output throughout its discharge cycle, making it a reliable power source for demanding applications.

A key feature of the Molicel P28A is its ability to handle a continuous discharge rate of 35A, which is particularly valuable in high-drain devices that require significant power over short periods. The 35A continuous discharge rating ensures that the battery can handle heavy usage without overheating or suffering from voltage drops. This characteristic is critical for applications like power tools, where the battery must provide consistent and substantial power without the risk of failure due to excessive current draw.

In addition to its high discharge capability, the Molicel P28A also offers a long cycle life. This means that the battery can be charged and discharged repeatedly over time without significant degradation in capacity, allowing for hundreds of charge cycles before the battery’s performance begins to noticeably decline. This extended lifespan makes the P28A a cost-effective and sustainable choice for users who need a dependable power source for prolonged use.

One of the key attributes of the Molicel P28A is its flat top design, which is a standard configuration for 18650 cells. This design makes the battery easy to integrate into various devices, including custom battery packs, and allows for reliable electrical connections. The P28A is an unprotected cell, meaning that it does not have built-in protection circuits for overcharge, over-discharge, or short circuit protection. As such, users must ensure that the battery is used with the appropriate protection circuitry, such as a Battery Management System (BMS) or an external protection circuit, to ensure safe and reliable operation. This additional level of safety is necessary to prevent potential risks associated with lithium-ion cells, such as thermal runaway or excessive discharge.

The Molicel P28A is engineered to provide a high energy density, ensuring that it delivers a substantial amount of power while maintaining a relatively lightweight profile. Weighing approximately 45.18g, it strikes a balance between providing sufficient power and remaining portable, making it ideal for use in applications where size and weight are crucial factors. This makes the battery a great option for use in handheld devices, electric vehicles, and any other equipment where a compact, high-capacity power source is required.

Lithium-ion technology, as seen in the P28A, is known for its stability and efficiency. The Molicel P28A benefits from the inherent qualities of lithium-ion cells, which include low internal resistance, minimal self-discharge rate, and a high energy-to-weight ratio. These attributes ensure that the battery can be used for extended periods before requiring a recharge, and it also minimizes energy loss during storage or when not in use. Additionally, the low internal resistance of the P28A contributes to efficient power transfer, allowing for faster charging times and a consistent discharge rate throughout its cycle.

The Molicel P28A also benefits from high safety standards, which are critical when using lithium-ion batteries in applications that involve substantial power demands. Although the P28A is an unprotected cell, it is built to adhere to industry safety certifications, ensuring that when used with appropriate protective circuits, it can deliver safe and reliable performance. Furthermore, its robust construction and high-quality materials ensure that it can withstand the rigors of high-drain applications, providing users with confidence that the battery will perform reliably under challenging conditions.
