feature
High energy density
- Mass energy density: 200-240 Wh/kg, far more than lithium iron phosphate (LFP), suitable for weight-sensitive applications (such as drones, high-end electronic products).
- Volumetric energy density: 500-600 Wh/L, high space utilization (such as light notebook batteries).
High Voltage Platform
- Nominal voltage 3.7V, full charge voltage 4.2V (partially 4.35V), higher output power than LFP (3.2V) at same capacity.
Excellent discharge performance
- Power type supports 5C-10C continuous discharge (13A-26A), which meets the instantaneous high power demand of power tools and electric vehicles.
- Low internal resistance: the internal resistance of ordinary type is about 30-50mΩ, while the power type can be lower than 15mΩ, which reduces energy loss.
Wide temperature adaptability
- Low temperature performance: -20℃ can still be discharged (capacity of about 50%), better than lithium iron phosphate (only 30% left at -20℃).
- High temperature on: 60 ℃ short-term work
