Molicel P45B
21700 4500mAh 45A Continuous Discharge — Ultra High-Drain Lithium-Ion Cell
The Molicel P45B is Molicel's highest-capacity 21700 cell, delivering 4500mAh at a continuous discharge rating of 45A. It represents the pinnacle of Molicel's NMC cell engineering — offering more energy than the P42A while maintaining the same exceptional current output.
Designed for next-generation e-mobility, robotics, and industrial power tools, the P45B features an ultra-low internal resistance profile that minimises heat generation under sustained high-current loads. Its robust construction and rigorous quality control make it a preferred choice for OEM battery pack manufacturers.
