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
American Lithium Energy
American Lithium Energy is an American cylindrical lithium-ion cell manufacturer for defence and industrial markets
American Lithium Energy was founded in 2006 and manufactures lithium-ion cells in Carlsbad, California, concentrating on the cylindrical 18650 and 21700 formats. Its catalogue spans NMC and silicon-anode chemistries, with the ALE model codes indicating cell format and rated capacity. The company has developed an internal safety layer, marketed as SafeCore, intended to interrupt thermal runaway inside the cell rather than relying on pack-level protection alone. Production is carried out in the United States, which positions the cells for defence, aerospace and industrial programmes that require a domestic or procurement-compliant supply chain. Its relevance lies in combining conventional cylindrical formats with onshore manufacture and cell-level safety engineering.
