Applications & Use‑Cases
The Molicel P60B is well suited to the following applications due to its 21700 format and high power performance.
eVTOL: Requires very high peak power, low internal resistance, and stable voltage during take off and climb phases.
Drones: Demands high gravimetric power density and fast current response to maximise thrust and payload.
Robotics: Relies on rapid transient power, cycle durability, and thermal stability for repeated dynamic motion.
Power Tools: Needs sustained high discharge and low voltage polarisation under continuous heavy load.
Mobility: Requires burst power, mechanical robustness, and wide temperature operation for responsive performance.

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.
