2. Why Molicel Cylindrical Cells?  
Top-tier high power performance
Molicel proprietary multi-tab design cuts internal resistance sharply, supporting large discharge current with slight voltage drop and low heat for high-power equipment.
Balanced power & energy options
Dedicated P (power) / M (high-capacity) series with high-nickel NMC material, meeting both strong acceleration and long endurance needs.
Fast charging & long cycle life
Custom electrolyte supports 3C–5C fast charging; over 1400 stable cycles with slow impedance rise to lower replacement costs.
Low-temperature adaptability & high safety
Exclusive cold-resistant electrolyte works stably at -40°C; optimized heat dissipation and pressure relief shell effectively prevent thermal runaway.
Consistent cell quality
Strict automated sorting on voltage, resistance and capacity reduces cell imbalance, lightens BMS load and extends overall pack lifespan.
