Highlights

  • Initial Power Cell units were delivered to the US Army DEVCOM C5ISR Center in August 2026.
  • Drone testing demonstrated a flight exceeding 75 kilometres using one battery pack.
  • An Australian manufacturing feasibility study remained under board consideration.
  • September-quarter closing cash was A$12.147m, with no customer receipts.
  • Defence qualification and potential procurement remain separate future decisions.

Li-S Energy Limited (ASX:LIS) develops lithium-sulfur and lithium-metal battery cells using specialised nanomaterials to improve energy-storage performance. Its September 2026 update brought together the first delivery of Power Cell units to the US Army's DEVCOM C5ISR Center, additional drone flight testing and an assessment of future local manufacturing. Those activities are evaluation and development milestones rather than confirmed commercial battery orders.

What the US Army Delivery Establishes

In August 2026, ASX:LIS supplied its first Power Cell-design lithium-sulfur cells to DEVCOM C5ISR for independent evaluation. The company described this as its first delivery to a US Government agency. No evaluation findings or procurement award had been disclosed in the 29 October quarterly report. Any subsequent supply arrangement depends on testing outcomes and the customer’s purchasing process.

Li-S Energy also entered a non-exclusive collaboration agreement with EPE Trusted to Protect on 2 September 2026. The arrangement provides access to a defence and security equipment network, but it does not represent a contracted sales volume. Separate evaluations involving MSubs and Safesky Systems were still progressing, with additional testing and reporting anticipated during the December 2026 quarter.

Drone Evidence and Scale-Up Work

The EATP Pegasus drone completed a flight of nearly two hours and more than 75 kilometres using a 382 Wh battery pack during Queensland testing. Li-S Energy (ASX:LIS) reported approximately 80% greater flight time and range than a comparable lithium-polymer configuration under its specified assumptions. Projections for future two-pack and solar-assisted configurations have not been demonstrated in those tests.

A feasibility assessment led by Hatch was nearing completion at quarter end. It considers a phased pathway towards annual capacity of one gigawatt hour and is supported by a $7.8m Australian Renewable Energy Agency grant. ASX:LIS had received a draft report for board consideration; no manufacturing construction commitment was reported.

Funding and Remaining Dependencies

For the September 2026 quarter, ASX:LIS recorded A$2.052m of net operating cash outflow and A$716k of investing outflow. Financing cash outflow was A$65k. Closing cash fell from A$14.98m to A$12.147m, and the company estimated approximately 5.9 quarters of funding at the reported operating outflow rate. No equity was raised during the quarter, and no debt facilities were available.

The A$231k of government grant receipts did not change the absence of customer receipts for the period. Commercialisation therefore remains dependent on technical qualification, customer acceptance and funding for any eventual manufacturing expansion.

Key Insights

Li-S Energy (ASX:LIS) has progressed from laboratory and flight demonstrations to formal defence-customer evaluation. The US Army assessment, partner testing programmes and manufacturing study address different stages of development. None establishes recurring product revenue. The September cash balance provides a dated measure of available resources while the company continues its qualification work.
