Product Details

• Discharge Rate: Lithium batteries have varying discharge rates. These batteries can handle a maximum discharge rate of 5.0C, which means they can deliver high power output in short bursts.
• Long Cycle Life: This battery maintains over 80% capacity even after 500 charge-discharge cycles at 0.5C, all at room temperature.
• Ultra-Low Self-Discharge: Batteries display varying self-discharge rates depending on their charge states. Specifically, self-discharge is notably higher at a 100% state of charge (SOC) in comparison to a 70% SOC.
• Wide Temperature Range: Lithium batteries function within a discharge temperature range of -20°C to 60°C. Custom low-temperature batteries are designed for various outdoor scenarios and can work in -40°C to 55°C.
