Applications & Use‑Cases
The CustomCells CC-HE-1 is well suited to the following applications due to its pouch form factor and balanced performance.
Drones: Demands high gravimetric power density for thrust and payload capacity, rapid current response for flight control, and stable voltage delivery across dynamic flight profiles.
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.
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
CustomCells
CustomCells is a German developer of application-specific lithium-ion pouch cells
CustomCells was founded in 2012 as a spin-off from the Fraunhofer Institute for Silicon Technology and operates from sites in Itzehoe and Tübingen. It designs and produces application-specific lithium-ion pouch cells in small and medium series, tailoring electrode formulation, format and performance envelope to individual customer programmes. Its high-energy cells use silicon-rich anodes to reach energy densities well above mainstream automotive cells, and have been developed for electric aviation, maritime and defence platforms. The model codes encode cell family and format, with the CC-HE prefix denoting the high-energy range. CustomCells occupies the space between research prototypes and mass production, supplying qualified cells at volumes the large manufacturers will not serve.
