Applications & Use‑Cases
The Inobat E33B is well suited to the following applications due to its pouch and high energy density 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
InoBat
InoBat is a Slovakian lithium-ion pouch cell manufacturer building custom cells
InoBat was founded in 2019 and is headquartered in Bratislava, Slovakia, where it develops and manufactures custom lithium-ion pouch cells for automotive, defence and specialist applications. It operates a research and pilot production line at Voderady, which allows chemistry and format to be tuned to an individual programme rather than drawn from a fixed catalogue. Its E series cells use nickel-based chemistry and target high energy density with European production and traceable supply. The company is scaling through a joint venture gigafactory in southern Slovakia and a further plant planned in Spain. InoBat's position rests on bespoke cell development backed by European manufacture.
