The LG HE2 18650 2500mAh 20A lithium-ion battery is a robust and high-performance power source designed for demanding applications, making it a top choice for those who need reliability and efficiency in their battery packs. This cell, with its flat-top terminals, is primarily intended for high-drain devices that require continuous and high discharge rates, providing both the capacity and power to meet the demands of various electronics, such as power tools, vaping devices, and even electric vehicles. With its lithium nickel manganese (INR) chemistry, the LG HE2 offers a balance of high capacity and robust discharge performance, delivering a nominal capacity of 2,500mAh and a continuous discharge rate of up to 20A.

One of the key highlights of the LG HE2 battery is its exceptional performance in both high-drain and everyday applications. With a nominal voltage of 3.6V, it can maintain stable output for long periods, and its high maximum discharge current of 20A ensures that it can keep up with even the most energy-demanding devices. The battery is equipped with a minimum capacity of 2,475mAh, ensuring that it consistently provides a substantial amount of energy even under more strenuous conditions. The cell is capable of being charged over 300 times, making it a durable and long-lasting option for a variety of applications. Its cycle life is an important consideration for users seeking longevity; it can last up to 300 cycles at a 10A discharge rate or 200 cycles at a 15A rate, maintaining 60% of its original capacity after these cycles, which reflects the solid build and efficient chemistry.

Charging the LG HE2 is also straightforward, with standard and fast charge options available. The standard charging process is done at a constant current of 1,250mA, followed by a constant voltage of 4.2V, with a cutoff current of 50mA, ensuring a full charge without the risk of overcharging. If you need to charge the battery quickly, the fast charge option is also available, with a constant current of 4,000mA, followed by the same constant voltage of 4.2V and a cutoff current of 100mA. This gives users flexibility when dealing with time-sensitive tasks while ensuring safe and efficient charging. The maximum charge current for the LG HE2 is 4,000mA, which is ideal for those needing faster turnaround times without compromising the battery's lifespan.

On the discharge side, the LG HE2 offers reliable and consistent power output. The standard discharge rate of 500mA ensures that the battery can handle light power demands over extended periods, while the fast discharge capability, ranging from 10A to a peak of 20A, allows it to keep up with high-energy devices that need substantial bursts of power. The battery's discharge voltage cutoff is 2.0V, ensuring that it doesn’t continue discharging past a point where it might cause damage to the internal structure. The battery is built to handle temperatures ranging from -20°C to 75°C during discharge, offering flexibility for use in various environmental conditions. Whether it’s in a high-heat or cold environment, the LG HE2 can be relied upon to maintain its performance, although it’s important to avoid exposing it to extreme temperatures for prolonged periods.

The battery’s physical design is optimized for convenience and safety. With a weight of just 48g, it is lightweight and easy to handle, whether you're integrating it into a battery pack or using it as an individual cell. This makes it a perfect choice for users who need a lightweight solution without compromising on power. The LG HE2 is also designed to operate efficiently within a wide range of temperatures. For charging, the operating temperature is between 0°C and 50°C, while for discharging, it can handle extreme cold and heat, with temperatures ranging from -20°C to 75°C. This feature ensures that the battery is adaptable for use in both high-performance and harsh conditions.

Storage considerations are also important for maintaining the longevity and safety of lithium-ion batteries. The LG HE2 should be stored at approximately 40% charge, with storage temperatures ranging from -20°C to 60°C for short-term storage (1 month), and -20°C to 45°C for medium-term (3 months). For long-term storage (1 year), it is recommended to keep the battery between -20°C and 20°C to prevent any potential degradation of capacity or performance. These storage guidelines ensure that users can store the battery safely when not in use while maintaining its optimal performance when it is recharged and put back into service.

The LG HE2 is a highly reliable and versatile lithium-ion battery, offering both high capacity and substantial discharge capabilities. Its INR chemistry, with its mix of lithium, nickel, and manganese, provides a combination of energy density and stability that is ideal for applications requiring high current and efficient power management. With a nominal capacity of 2,500mAh, high discharge current tolerance, and long cycle life, the LG HE2 stands out as a superior choice for demanding energy storage needs, providing users with a battery that offers both longevity and power. Whether you're using it for power tools, vaping devices, or other high-drain applications, the LG HE2 delivers exceptional performance, reliability, and safety.
