LFP HB18650 1500mAh 3.2V High Rate Cylindrical Cell 3C Charge 5C Discharge -40℃~60℃ Long Life

Product Overview
The Ecolite LFP HB18650 is a high-performance cylindrical lithium iron phosphate (LiFePO4) cell designed for applications requiring high discharge rates, wide temperature operation, and exceptional cycle life. With 1500mAh capacity and 3.2V nominal voltage, this 18650 cell delivers reliable power for portable devices, power tools, energy storage systems, and automotive applications where safety and longevity are paramount.

High Rate Capability for Demanding Loads
Supporting continuous charging up to 3C (4.5A) and continuous discharging up to 5C (7.5A), this cell provides the high current performance needed for power-hungry applications. With pulse discharge capability up to 40C (3 seconds), it can handle brief high-current demands such as motor starting or peak power assist, making it ideal for hybrid systems and high-drain devices.

Extreme Temperature Performance
Engineered to operate reliably across an exceptional temperature range, the cell supports both charging and discharging from -40℃ to 60℃. This extreme temperature tolerance ensures consistent performance in cold storage facilities, outdoor installations, Arctic environments, and high-temperature industrial settings—all without performance degradation.

Exceptional Cycle Life for Long-Term Value
Rated for over 6000 cycles at 100% depth of discharge with 80% state of health retention (25℃, 1C charge/discharge), this cell outlasts conventional lithium-ion alternatives by a significant margin. The long service life reduces replacement frequency and total cost of ownership in applications requiring daily cycling.

Inherent Safety & Stability
LiFePO4 chemistry provides the highest level of safety among lithium-based cells, with no risk of thermal runaway, smoke, or explosion even under abuse conditions. The cell's robust construction ensures mechanical stability and reliable performance throughout its extended service life.
