* The discharge current is cut off at 80°C.
Compared to its predecessor, the P45B, it offers significantly higher runtime, better retention, and a slower heating rate, effectively doubling the cycle life. This makes it ideal for high-demand applications where both power and endurance are essential.
Feature 1
The high-nickel layered oxide cathode is engineered to deliver an impressive energy density of 265 Wh/kg.
Feature 2
The high-wettability polymer separator is engineered to support a remarkable discharge current of 60A.
Feature 3
The engineered graphite anode is designed to support a fast charge rate of 5C while ensuring high safety standards.
Feature 4
The advanced silicon-carbon composite anode technology offers a significant enhancement in battery longevity, doubling the cycle life from 700 to 1,400 cycles under a 100W discharge condition*.
* This improvement is achieved under conditions of a +1C charge rate and a -100W discharge rate.
Feature 5
The low-temperature electrolyte formulation is optimized for precise temperature control, allowing the system to deliver peak power of 238W in -10°C*.
*This performance is based on a state of charge (SOC) of 100% within 10 seconds.
Feature 6
The interface engineering has been meticulously optimized to achieve exceptionally low impedance, measured at just 13.5 mΩ.
