Applications & Use‑Cases
The Molicel P60C is well suited to the following applications due to its cylindrical 21700 and high power performance.
Aviation: Requires high specific energy for extended flight duration, high power-to-weight ratio for climb performance, and reliable operation across wide temperature ranges at altitude.
Motorsports: Demands sustained high discharge under competitive load profiles, rapid transient response for acceleration, and thermal stability to maintain performance during race conditions.
E-Mobility: Requires balanced energy and power density for range and acceleration, high cycle life for daily use, and robust calendar life to ensure long-term reliability.
General Applications: Suitable for applications requiring reliable lithium-ion performance with proven cycle life, consistent capacity delivery, and operational safety across diverse use cases.

Motorsports
McMurtry Automotive: Faster cell evaluation
McMurtry Automotive used The Voltt and validated cell models to evaluate the transition from the Molicel P45B to P50B during early pack concept development.
Side by side modelling enabled rapid comparison of electrical and thermal behaviour, avoiding lengthy physical test campaigns. This approach reduced cell evaluation time by seven months, allowing the team to lock in cell selection and pack assumptions earlier while lowering technical risk and accelerating vehicle development.

Manufacturer Background
Molicel
Molicel is a Taiwanese manufacturer of high-power cylindrical lithium-ion cells
Molicel is the cell brand of E-One Moli Energy, a Taiwanese manufacturer whose technology traces back to lithium battery research begun in Canada in the 1970s. The company produces cylindrical 18650 and 21700 cells engineered for high continuous discharge, fast charge acceptance and thermal stability under sustained load. Its P series power cells and higher-capacity energy variants are used in eVTOL aircraft, motorsport and performance vehicles, power tools and aerospace systems, where discharge rate rather than energy density sets the design limit. Manufacturing is based in Taiwan with a long-standing Canadian research presence. Molicel is the reference supplier for many programmes that cycle hard and frequently.
