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
Tenpower
Tenpower is a Chinese cylindrical lithium-ion cell manufacturer
Jiangsu Tenpower Lithium was founded in 2006 and is based in Zhangjiagang, China, where it develops and manufactures cylindrical lithium-ion cells in the 18650 and 21700 formats. Its catalogue covers both lithium iron phosphate and nickel-based chemistries, tuned for high power delivery, thermal stability and fast charging. The company supplies power tools, electric two-wheelers and light mobility, vacuum cleaners and energy storage customers across more than forty countries, having shipped cells in the billions since founding. It is a subsidiary of a listed Chinese industrial group, which underwrites its manufacturing capacity. Tenpower is an established high-volume supplier in the cylindrical power-cell segment rather than a recent entrant.
