From Lab to Field: HPQ and Novacium Secure First Battery Order from European Drone Manufacturer Using GEN4 Cells

• The initial order represents a first step in the commercialization of cylindrical battery pack formats and follows recent capacity testing of HPQ Silicon’s GEN4 21700 cells
• The customer operates across professional, industrial, and defense drone markets.
• The initial battery pack order, designed for high-endurance drone applications, is based on an 8S2P configuration delivering between 10,000 mAh and 13,400 mAh. Discussions are ongoing regarding a potential 8S3P configuration, which could deliver between 15,000 mAh and
  20,100 mAh

MONTREAL, Canada — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: 8PY1), today announced that its strategic partner, Novacium, has received an initial battery pack order from a European drone manufacturer. The order represents a first step in the commercialization of high-capacity lithium-ion battery packs for drones. The counterparty remains undisclosed for confidentiality reasons.

This order follows GEN4 performance results announced on April 15, 2026, in which 21700 cells achieved up to 7,030 mAh under extended-voltage test conditions, with energy densities reaching 330.9 Wh/kg and 937.5 Wh/L. Laboratory testing also demonstrated over 96% capacity retention after 100 deep-discharge cycles, supporting potential use cases requiring high endurance and repeated cycling [1].

The cylindrical battery pack formats proposed to the customer are based on an 8-series (8S) architecture and are offered in two configurations: 8S2P and 8S3P. Both configurations utilize GEN4 21700 cells designed to combine high discharge capability with the energy density advantages of silicon-based anode materials.

At the pack level, the 8S2P configuration sold to the customer is expected to deliver approximately 10,000 mAh to 13,400 mAh. The customer has also requested pricing for an 8S3P configuration 8S3P configuration packs, which could deliver approximately 15,000 mAh to 20,100 mAh.

“Drone manufacturers are actively looking for ways to extend flight time without increasing weight,” said Jed Kraiem, COO of Novacium. “GEN4 is showing exceptional and unique characteristics in that direction, and this initial order, along with ongoing discussions reflect growing interest from advanced industrial users.”

HPQ holds exclusive North American commercialization rights for Novacium’s GEN3 and GEN4 silicon-based anode materials under the HPQ ENDURA+ brand. While this order was secured in Europe, HPQ is positioned to offer 8S2P and 8S3P battery pack configurations for drone applications in North American markets.

“This development reflects the continued advancement of our technology toward commercial applications over the coming quarters,” said Bernard Tourillon, President and CEO of HPQ Silicon. “HPQ stands to benefit directly through its ownership stake in Novacium. More importantly, the battery pack configurations being delivered represent a foundational step toward standardized solutions that can be deployed across both European and North American markets.”
