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
Grepow
Grepow is a Chinese lithium polymer pouch cell manufacturer specialising in high-discharge cells
Grepow was founded in 1998 and is headquartered in Shenzhen, producing lithium polymer pouch cells and complete battery packs. The company is best known for high-discharge cells used in drones, radio-controlled models and other uncrewed platforms, sold under its Tattu and Gens Ace brands as well as to OEM customers. Its GRP model codes encode cell thickness, width and length in millimetres, reflecting a catalogue built around custom and shaped pouch formats. Grepow also produces low-temperature, high-voltage and semi-solid-state variants for industrial and medical use. Its relevance rests on volume production of high-rate pouch cells in formats the large cylindrical manufacturers do not serve.
