The IMREN 50S 26650 5000mAh 50A Rechargeable Lithium Battery is a high-performance power cell designed to meet the demands of high-drain applications while providing exceptional longevity and reliability. Engineered with a robust 5000mAh capacity, this battery delivers a sustained and consistent power output, making it an excellent choice for demanding electronic devices, including high-powered flashlights, vaping devices, power tools, and other energy-intensive equipment. With its advanced lithium-ion chemistry, it ensures superior efficiency, a stable voltage supply, and a long cycle life, making it an optimal choice for users seeking both power and durability.

Featuring a nominal voltage of 3.7V, the IMREN 50S 26650 battery is designed to maintain a consistent discharge curve, ensuring that connected devices receive a steady flow of energy throughout the discharge cycle. Unlike traditional batteries that experience a gradual drop in voltage over time, this lithium-ion cell retains its efficiency until it reaches depletion, offering enhanced performance and prolonged usability. The impressive 50A discharge current capability allows it to power high-drain devices with ease, making it suitable for applications requiring rapid energy output without compromising safety or longevity.

Charging this battery is efficient and convenient, with a CCCV (constant current, constant voltage) charging method that ensures precise and safe recharging. It supports a charge current of 1.50A and reaches a full charge at 4.20V±0.05V with a 150mA cut-off. With an average charging time of 2.5 to 3 hours, users can expect a quick turnaround to keep their devices running without long downtimes. The battery's low internal impedance, measured between 13 and 16mΩ, ensures minimal resistance, contributing to its high energy efficiency and optimal power delivery.

Designed for durability, the IMREN 50S 26650 battery can withstand a wide range of operating conditions. It performs reliably within a charging temperature range of 0℃ to 45℃ and can safely discharge in temperatures as low as -20℃ and as high as 60℃. This makes it ideal for outdoor and industrial applications, where environmental conditions may vary significantly. Additionally, the battery maintains its integrity in storage conditions between -20℃ and 45℃, with a recommended humidity level of 75% RH or lower to ensure optimal performance over time.

Weighing approximately 62g, this battery is engineered with a compact yet sturdy design, making it easy to integrate into a variety of compatible devices. Measuring 26mm in diameter and 65mm in height, it conforms to the standard 26650 battery size, ensuring compatibility with devices that require this specific form factor. The pointy-top positive terminal ensures a secure connection, reducing the risk of power interruptions and ensuring consistent energy delivery.
