When a company clears a key regulatory hurdle between technical validation and commercialization, the conversation begins to shift. HPQ Silicon announced August 6, 2026 that its HPQ ENDURA+ Gen4 21700 lithium ion cells achieved UN 38.3 transportation certification, enabling international shipment for customer qualification, evaluation and commercial applications. The certification supports ongoing evaluations by multiple potential buyers in the drone and defence sectors, where global defence battery demand exceeded 4 GWh in 2025, with nearly 40% generated by unmanned drone systems. This advances HPQ further toward commercial execution.
WHAT YOU NEED TO KNOW
Regulatory Gateway: UN 38.3 removes a key transportation hurdle, allowing HPQ ENDURA+ Gen4 cells to be shipped internationally for customer qualification, evaluation and commercial applications across drone and defence markets.
Multiple Evaluations: The AA NOVA 6S3P drone battery pack, developed following work with a European drone manufacturer, and other battery platforms are being evaluated by multiple potential buyers active in the drone and defence sectors.
Defence Market Scale: Global defence battery demand exceeded 4 GWh in 2025, with nearly 40% generated by unmanned drone systems, a share HPQ says has more than doubled in five years.
Higher Margin Focus: Rather than pursuing high volume, lower margin markets, HPQ’s strategy targets lower volume, higher margin defence and specialty applications that management believes better match its current production capacity.
Commercial Timing: Customer qualification activities span evaluation, feedback, optimization and revalidation across multiple organizations. With the usual forward looking caveat, CEO Bernard Tourillon said he believes a first commercial order could occur during this quarter based on information available to him.
STRATEGIC IMPLICATIONS
The defence and advanced drone battery market places significant importance on incremental performance improvements. During the interview, Tourillon explained that improvements in battery performance can directly affect drone efficiency, including endurance and weight. These improvements can matter where operating time, payload capacity and performance are important.
The AA NOVA 6S3P battery platform was developed following work with a European drone manufacturer, showing how customer requirements are helping shape commercial development. HPQ is focusing on applications where management believes performance differentiation can support higher margins and better align with available production capacity.
The commercial opportunity extends beyond a single prospective customer. Tourillon clarified that multiple potential buyers are evaluating HPQ battery solutions at different stages. Some are in evaluation and feedback, another is in optimization and others have reached revalidation. He also confirmed that government entities are represented among the parties involved and said government activity currently involves mostly defence departments.
The global military drone market is estimated at approximately US$35 billion in 2026 and projected to exceed US$109 billion by 2031, according to market research cited by HPQ, with North America accounting for roughly 40% of global demand. HPQ holds exclusive North American commercialization rights for Novacium’s silicon based battery technology under the HPQ ENDURA+ brand.
UN 38.3 does not represent the end of every certification requirement. Tourillon confirmed that finished drone battery packs will require an additional certification process once pack designs are finalized. He described this as part of the normal commercialization process and said management does not currently expect it to prevent a first commercial order.
CEO BERNARD TOURILLON
Tourillon said HPQ has resolved many technical challenges surrounding its battery technology and is increasingly focused on commercial work required to develop products customers are prepared to buy.
Management’s strategy is to prioritize lower volume, higher margin opportunities while production capacity remains limited. Tourillon also said an initial commercial reference could help generate additional interest.
Qualification programs are progressing at different stages across multiple organizations, including evaluation and feedback, optimization and revalidation.
When asked whether the first commercial order was more likely in Q3, Q4 or beyond, Tourillon cautioned that his response was forward looking but said, based on the information he is receiving, he believes an order could occur during the current quarter.
Forward looking expectations regarding potential orders are subject to customer qualification, certification, testing and other risks and uncertainties.
INVESTOR TAKEAWAY
HPQ Silicon is progressing from battery technology development toward prospective commercial battery supply. UN 38.3 certification allows its Gen4 cells to be shipped internationally for customer qualification, evaluation and commercial applications, addressing a key transportation requirement on the path toward potential sales.
The company’s focus on higher margin defence and drone applications aligns its current production capacity with markets management believes offer attractive commercial opportunities. Multiple potential buyers are evaluating HPQ battery platforms, with qualification programs advancing through feedback, optimization and revalidation.
There are still steps ahead. Finished drone battery packs will require additional certification and individual qualification programs have uncertain outcomes. HPQ has not yet announced a commercial purchase order associated with these programs.
However, with UN 38.3 certification complete, multiple potential buyers evaluating HPQ battery solutions and management indicating that a first commercial order could occur during the current quarter, subject to forward looking risks, HPQ has advanced another step from technical validation toward prospective commercial adoption.
