Langhus is preparing to lock in a strategic partnership with PowerCap Un Limited covering Scandinavian and broader European exclusive distribution, manufacturing participation, R&D collaboration, and BESS project deployment. The combined capital plan (approximately US$157M across Australian R&D, European Phase 1 assembly and European Phase 2 cell/assembly/data centre) represents a substantial commitment underwritten by PowerCap's continued technical, commercial and financial viability. This document sets out independent due diligence findings on PowerCap prepared from the publicly-available PowerCap pitch deck (August 2026), publicly-available reporting on PowerCap deployments and certifications, forensic patent lookup, and benchmarking against the sodium-ion battery sector globally. The document identifies material findings, poses diligence questions that Langhus should get PowerCap to answer before further commitment, and recommends specific contractual protections Langhus should build into its PowerCap agreements. This is not an assessment of Langhus Energy's own commercial thesis or model, and does not constitute investment advice.
PowerCap is a genuine early-stage sodium-ion battery company with real product deployments, meaningful certification progress (TÜV IEC 62619, PPP 51096A), and demonstrable engineering capability under founder-CEO Dane El Safty. As a technology partner for Langhus, the underlying company is credible. However, five material findings should be resolved before Langhus commits substantial capital or locks in long-term exclusivity terms, and additional supplier-viability, warranty and product-liability considerations require specific contractual protection. The most critical finding is a forensic IP issue: publicly-available PowerCap product specifications reference Patent PCT/AU2024/050514 (WO2024239054A1), which Google Patents shows as assigned to CI Corp Pty Ltd — not PowerCap Un Limited. This raises an urgent question about who actually owns the fundamental sodium-ion chemistry IP that Langhus's exclusive rights would depend on. Additional findings: PowerCap's "5.2 GWh manufacturing capability" refers to Chinese contract manufacturing lines, not owned production capacity; the "37 exclusive manufacturing licences" have no named licensor or disclosed terms; certifications for US utility-scale deployment (UL 1973, UL 9540) are future-dated in the August 2026 pitch; PowerCap's own technical specification states ≤8,000 cycles while the current website advertises 10,000+ cycles; and PowerCap's Australian residential go-to-market is impaired pending CEC approved-product listing. The Natron Energy collapse in September 2025 — a fully UL 1973 certified sodium-ion pioneer with operating Michigan manufacturing, US$25M unfulfilled orders, and Chevron / United Airlines backing that nonetheless could not raise its next round — provides a critical case study for how Langhus should structure its exposure. None of these findings suggest PowerCap is not a viable partner. All of them suggest Langhus should structure its agreements with specific contractual protections — including technology-provider substitutability, warranty back-to-back with the Chinese cell OEM, product liability insurance, and insolvency-survival warranty rights — rather than relying on PowerCap's pitch representations. This document sets out the findings, specific diligence questions Langhus should put to PowerCap, recommended contractual protections, and red-line issues that should trigger reconsideration of the partnership.
This document assesses PowerCap Un Limited as a technology, manufacturing and commercial partner for Langhus Energy's European commercialisation platform. The assessment covers:
This assessment does not cover: Langhus Energy's own commercial thesis, financial model, capital structure, or investor positioning. Langhus's 5-year model, European pipeline conversion assumptions, and BESS trading economics are outside the scope of this document.
Findings are drawn from publicly available sources — the PowerCap pitch deck (August 2026), the PowerCap corporate website (powercap.com.au), the PowerCap product technical specification, industry press coverage across pv-magazine, ESS News, Renew Economy and PV Magazine Australia, Google Patents public records, and benchmarking data from BloombergNEF, Morgan Stanley, IRENA and named sodium-ion competitor filings and disclosures. No non-public information has been used. Where a finding requires verification against non-public PowerCap information (e.g. licence terms, manufacturing agreements), this is flagged and formulated as a diligence question for Langhus to put to PowerCap.
PowerCap Un Limited is a Brisbane-headquartered sodium-ion battery company founded by Dane (Ahmed) El Safty, a former Chevron/Shell chemical engineer with prior experience in petroleum extraction technology. The company has been publicly active since 2020 and has delivered actual sodium-ion battery deployments to residential, commercial and industrial customers in Australia, Indonesia, and — more recently — Europe and the United States.

PowerCap is not a paper company. Publicly-verifiable deployments exist. The founder's engineering background is real and the company has been engaged with industry press consistently since December 2024. TÜV IEC 62619 and PPP 51096A certifications are meaningful achievements — PowerCap has publicly represented itself as the first Western sodium-ion battery manufacturer to achieve both. AGL has publicly indicated it is evaluating sodium-ion technology, which suggests utility-grade interest exists in the Australian market. For Langhus's purposes, PowerCap represents a credible technology partner underneath the specific findings and diligence items set out below.
A publicly-available PowerCap product specification references Patent No. PCT/AU2024/050514. Google Patents lookup reveals this as WO2024239054A1 — "Smart uninterruptible power supply system". The inventor is listed as Ahmed El Safty (same as Dane El Safty per public reporting). The assignee is CI Corp Pty Ltd, not PowerCap Un Limited. PCT status is shown as ceased, though national phase applications may retain independent status. The patent concerns UPS / power-management architecture — not the fundamental sodium-ion chemistry.
Why this matters for Langhus: Langhus's exclusive Scandinavian and European distribution rights are only as valuable as PowerCap's ability to grant them. If key PowerCap IP is held by an El Safty family holding vehicle (or any entity other than PowerCap Un Limited), the exclusive rights Langhus is negotiating may not be enforceable against third parties who could obtain licences from the IP-owning entity, or may not survive a change of control at PowerCap. Langhus's US$143M European manufacturing commitment would rest on a partnership whose IP foundation is not what it appears to be.
Preferred outcome: Full chain-of-title documentation showing all PowerCap-relevant IP (chemistry, cell design, BMS, EMS, VPP, packaging) is owned by or exclusively licensed to PowerCap Un Limited with rights that flow through to Langhus under the distribution agreements.
The PowerCap pitch describes "37 exclusive manufacturing licences and proprietary technologies" spanning cell chemistry, materials, cell manufacturing, energy intelligence, power & storage systems, specialised systems, and manufacturing know-how. The pitch does not name the licensor(s), disclose royalty economics, specify territorial scope, or explain how "exclusive" is defined against 100+ Chinese sodium-ion producers holding overlapping IP.
Why this matters for Langhus: If PowerCap is a licensee rather than a first-principles IP owner for material portions of the 37 items, Langhus's exclusive European rights are sub-licences of PowerCap's licences — with all the same limitations, termination triggers, and change-of-control provisions. Langhus needs to know whether the underlying licensor has veto rights, minimum-royalty triggers, or the ability to terminate that could cascade to Langhus's rights.
Preferred outcome: Copies of all material licence agreements with named licensor(s), licence terms, royalty economics, exclusivity carveouts, termination triggers, IP indemnity provisions, change-of-control mechanics, and sub-licensing rights that support Langhus's downstream distribution rights.
The pitch presents "5.2 GWh current manufacturing capability through established manufacturing lines in China" as a de-risking factor. This appears to refer to contract manufacturing capacity available through Chinese cell/assembly partners — not owned or long-term-reserved capacity dedicated to PowerCap. The pitch does not identify the Chinese manufacturing partner(s), the terms of the manufacturing relationship, or the specific capacity committed to PowerCap.
Why this matters for Langhus: If PowerCap needs to fulfil the 800 MWh Power Yield OÜ tender in 2027, or the 2.4-3.2 GWh follow-on program, or the broader 14.104 GWh European pipeline, PowerCap must have contractual claims on manufacturing capacity that Langhus can rely on. Contract manufacturing partners typically prefer larger customers when capacity is constrained. Chinese cell makers (CATL, BYD, EVE, HiNa) all sell into the Australian and European markets both directly and through white-label channels — some of PowerCap's manufacturing partners may become PowerCap's competitors.
Preferred outcome: Named Chinese manufacturing partner(s), manufacturing agreements, committed PowerCap capacity, exclusivity provisions, minimum order obligations, cell pricing formulas, QC rights, tooling ownership, step-in rights, and geopolitical/export controls disclosure.
The PowerCap certification page lists UL 1973 as "Sep 2026", IEC 62477 as "Sep 2026", and UL 9540 & UL 9540A as "Oct 2026". The pitch itself is dated August 2026. These are future-dated on the document's own timing. PowerCap's own certification page bottom disclaimer reads: "Certification claims and scopes to be checked against final issued certification documentation prior to circulation."
Why this matters for Langhus: UL 1973 (stationary batteries) and UL 9540 / UL 9540A (energy storage systems and installation) are foundational for utility-scale BESS deployment in the US and are increasingly expected in European utility procurement. IEC 62477 (power electronic converter systems) is required for grid-connected inverter safety compliance. The Power Yield OÜ 800 MWh Germany tender and the 14.104 GWh European pipeline will require complete and current certification packages. Langhus must know exactly what is certified today, what is genuinely on track for near-term issuance, and what remains outstanding.
Preferred outcome: Current certification status with certificate numbers, issue dates, scope of coverage, and issuer contact for verification. For pending certifications: certifier engagement documentation, testing status, expected issuance date, and contingency plan if certifications are delayed.
PowerCap's current corporate website advertises "10,000+ cycles" for the POD system. A publicly-available PowerCap technical specification states "≤8,000 cycles at 25°C, ≤0.5C to ≥70% retention." A 20-25% cycle-life discrepancy between marketing and technical documentation is material for BESS underwriting because cycle life directly drives lifetime revenue, LCOS (levelised cost of storage) and payback economics.
Why this matters for Langhus: The Langhus 5-year model, the Power Yield OÜ pricing, the BESS trading economics, and any customer LTSA (long-term service agreement) commitments will depend on cycle-life assumptions. If the true underwriting cycle life is closer to 8,000 than 10,000+, Langhus's economics change. This may also reflect different product generations, different test protocols, or different end-of-life retention definitions (70% vs 80% retention makes a material difference to bankable life).
Preferred outcome: Independent third-party cycle-life test curves at 0.25C, 0.5C and 1C, at multiple depth-of-discharge levels, at multiple temperature ranges. Reconciliation of the website claim vs technical spec. If different generations or test protocols underpin the two figures, a clear technical explanation.
Dane El Safty (CEO / Founder) and Elisa El Safty (CFO responsible for "Finance | Business Oversight | Governance") share a distinctive surname. The relationship is not disclosed in the offer document — it may be spousal, sibling, parent-child, or coincidental. If related, a family-member CFO structure would require appropriate disclosure of related-party transactions and independent-director oversight. This is a diligence question, not yet an identified governance defect: the relationship and the framework of independent oversight need to be confirmed. Langhus should understand how PowerCap manages related-party governance before entering a long-term commercial relationship where PowerCap financial reporting and financial performance representations underpin Langhus's own capital deployment decisions.
Chris Dryden has been publicly quoted in industry press (pv-magazine, ESS News) as "General Manager, Product Development and Manufacturing" of PowerCap since at least December 2024, representing the company on technical questions including BMS, inverter compatibility, and sustainability. Dryden does not appear on the current pitch deck leadership team page (Kenneth Ingbritsen, Dane El Safty, Elisa El Safty, Jonathon Reynolds, Mitchell Orval). Langhus should clarify whether Dryden remains with PowerCap, and if so what his role is — the GM Product Development position is the technical counterpart Langhus's engineering, R&D and product teams will interface with on an ongoing basis.
The pitch discloses 204,570,335 existing shares on issue but does not disclose the history of how these were issued, at what prices, on what terms, or whether preferential rights exist. Langhus should understand the PowerCap capitalisation history and any existing preferential rights (liquidation preference, participation, anti-dilution) that could affect PowerCap's flexibility in future strategic transactions with Langhus. ASIC extract for PowerCap Un Limited (ACN, corporate history including any prior names, current director and share register) should be obtained as a routine step.
Two smaller observations sit at the level of disclosure quality: (a) the pitch describes CEO Dane El Safty as "Founder | Technology Vision | Principle Engineer" (correct spelling: Principal); (b) the entity name "PowerCap Un Limited" is a non-standard corporate designation (standard Australian public unlisted company suffix is "Limited" or "Ltd"). Neither is material in isolation. Both indicate the PowerCap raise document has not been through senior legal / advisor review of the standard expected at institutional-raise pricing. For Langhus's purposes, this means Langhus should ensure all Langhus-PowerCap commercial documentation is produced to a higher standard of review than the PowerCap raise pitch, and that the corporate history is properly confirmed via ASIC extract as noted in Finding 08.
PowerCap's sodium-ion products do not presently appear to have the required Australian Clean Energy Council (CEC) approved-product listing, which prevents access to the federal battery rebate (approximately A$300/kWh) and most state incentives under the 2025 Cheaper Home Batteries Program. The CEC approved-product list currently contains over 1,000 lithium-based batteries. LFP competitors have a structural 20-40% net-of-rebate price advantage in the Australian residential market until PowerCap-specific product approval is secured. The regime is transitioning to SA TS 5398 with battery approval requirements changing through 2026-27, so this is likely a PowerCap product-approval question rather than an immutable exclusion of sodium chemistry — but the timing and PowerCap's application status are not disclosed in the raise document. This is not directly relevant to Langhus's European commercialisation focus, but Langhus should be aware that PowerCap's Australian revenue base is constrained until this is resolved, which affects PowerCap's overall financial runway and negotiating position.
The sodium-ion category has moved decisively from laboratory to commercialisation during 2025-2026. Understanding PowerCap's position relative to global category leaders is essential for Langhus to price the strategic value of the PowerCap partnership.

Sodium-ion category consolidation is real and accelerating. Morgan Stanley's June 2026 sector coverage projects sodium-ion to reach 20% of battery deployment market share by 2030 and 37% by 2035, with US$800B in new investment required. The Morgan Stanley research specifically identifies CATL and GM/Peak Energy as primary category beneficiaries. BloombergNEF's December 2025 Battery Price Survey put stationary-storage LFP packs at US$70/kWh (down 45% year-on-year) — meaning sodium-ion is currently more expensive than LFP at pack level, with cost crossover expected 2027-28.
What this means for Langhus: Langhus's PowerCap partnership is not a bet on sodium-ion becoming a commercial chemistry — that debate is settled and sodium-ion has won a role. It is a bet on PowerCap specifically capturing meaningful share of a category being dominated by better-capitalised global players. The value of Langhus's exclusive European rights depends heavily on PowerCap's ability to differentiate on Western sovereignty, product design, safety, and BMS/EMS integration in specific European segments where CATL/BYD Chinese product may face regulatory, procurement or geopolitical friction.
Natron Energy — a Santa Clara-based sodium-ion battery company founded 2012 by a Stanford PhD — ceased operations on 3 September 2025. Its board determined on 27 August 2025 that "efforts to raise sufficient new funding were unsuccessful." Its primary shareholder (Sherwood Partners) attempted asset sale and found no buyers. All 95 employees terminated. Holland, Michigan factory permanently closed. Planned US$1.4B / 24 GWh gigafactory in Rocky Mount, North Carolina cancelled.
What Natron had at the point of collapse: UL 1973 certification (achieved 2020 — the first sodium-ion battery ever to meet the standard); operating Michigan plant (opened May 2024, 600 MWh annual capacity); patented Prussian blue electrode chemistry with claimed 50,000+ cycle life; approximately US$25M of orders already placed by customers; strategic investors including Chevron, United Airlines, Prelude Ventures; IRA support secured; 12 years of technology development runway; reported prior valuation approximately US$1.6B.
What killed it: The board could not raise the next funding round. Existing investors declined. Prospective investors declined. The company had orders it could not fulfil — reportedly held up pending UL certification of a newer product variant. Working capital ran out. Per TechCrunch: "Natron investors balked at releasing more funds, leaving the startup facing a cash crunch."
Why this matters directly for Langhus's PowerCap partnership decision: Langhus is preparing to commit to PowerCap as its exclusive European technology partner, put PowerCap product into an 800 MWh Power Yield tender, negotiate approximately US$143M of European manufacturing expenditure, and become the party contractually responsible to European end customers for 10-15 years of warranty and performance. If PowerCap encounters a Natron-equivalent capital event — inability to raise the next round, working-capital gap, delayed certification of a critical product variant — Langhus's platform value materially depends on how well its agreements with PowerCap have been structured to survive that event. Successful chemistry, meaningful certifications, operating manufacturing, real customer orders and marquee investors did not save Natron. The lesson is that Langhus should not assume PowerCap's next capital event will succeed simply because the current one is being conducted. Contractual protections identified below (technology substitutability, warranty back-to-back with the Chinese cell OEM, escrow of critical technical documentation) are the mechanisms that translate this lesson into actionable structuring.
The following questions should be put to PowerCap before Langhus commits material capital or executes definitive exclusivity documentation. Answers should be provided in writing with supporting documentation where relevant.
The following contractual protections should be built into the Langhus-PowerCap distribution, manufacturing, and R&D agreements to protect Langhus's capital deployment against the material findings identified above. These are protections independent of the diligence answers — they should exist in the agreement regardless of how the diligence responses land. The Natron Energy collapse (Section 05) elevates the importance of technology-provider substitutability, warranty back-to-back, and insolvency-survival provisions.
The following would be red-line findings that should trigger reconsideration of the scope, terms, or continuation of the Langhus-PowerCap partnership. These are not routine diligence issues but structural findings that would change the nature of what Langhus is buying.
If the fundamental sodium-ion chemistry IP (cell design, cathode, anode, electrolyte, BMS core algorithms) is not owned by or exclusively licensed to PowerCap Un Limited with full rights to grant Langhus enforceable European sub-licences — reconsider. Langhus cannot build a European commercialisation platform on IP rights that PowerCap cannot legitimately grant.
If PowerCap's Chinese manufacturing partner is a company that already competes (or is likely to compete) in the European stationary storage market under its own brand or through other white-label channels — reconsider. Langhus's European volume commitments would be funding a competitor.
If UL 1973 or UL 9540 certification for the utility-scale BESS product cannot be secured within a defined post-signing window (e.g. 6 months), or if the certifications when issued have material scope limitations that exclude the Langhus European use cases — reconsider. Langhus's Power Yield OÜ tender and broader European pipeline depend on complete certification packages.
If prior PowerCap capital raises include liquidation preferences, anti-dilution provisions, or drag-along rights that materially constrain PowerCap's flexibility to work with Langhus on preferential pricing, exclusive commitments, or joint IP creation — reconsider. The Langhus partnership requires PowerCap to have operational and financial flexibility that pre-existing investor rights may constrain.
If diligence reveals additional undisclosed related-party structures (beyond CI Corp Pty Ltd and the CEO/CFO relationship) that materially affect PowerCap's IP, revenue, or governance — reconsider. Long-term commercial partnerships require transparency about the entity Langhus is dealing with.
If PowerCap cannot demonstrate a credible forward capital plan through to self-funding free cash flow, and if the Langhus agreements do not include workable technology-substitutability protections (Section 07) enabling Langhus to source equivalent product from qualified alternative suppliers if PowerCap fails defined benchmarks, then Langhus's ability to fulfil its own customer commitments becomes hostage to PowerCap's next capital event succeeding — reconsider scope of exposure. The Natron Energy collapse (Section 05) demonstrates that even fully-certified, operationally-established, strategically-backed sodium-ion companies can fail on the next funding round. Langhus's platform value should not be structured so as to collapse alongside a single supplier's capital event.
PowerCap Un Limited is a credible early-stage sodium-ion technology company with real product deployments, meaningful certification progress, and a technically capable founder. As a technology partner for Langhus Energy's European commercialisation platform, PowerCap represents a viable option. However, the material findings identified in this document — particularly the CI Corp Pty Ltd IP chain-of-title issue, the undisclosed licensor of the 37 exclusive manufacturing licences, the future-dated utility-scale certifications, the cycle-count inconsistency, the Chinese contract manufacturing dependency, and the warranty / product liability / bankability chain that a Langhus-scale distributor must protect against — are all resolvable through appropriate diligence responses and contractual protections, but they are not issues Langhus should proceed without addressing. The recommended approach is: (a) put the diligence questions in Section 06 to PowerCap and obtain written responses with supporting documentation before executing definitive exclusivity documentation; (b) build the contractual protections in Section 07 into every material Langhus-PowerCap agreement — with particular attention to technology-provider substitutability and warranty back-to-back with the Chinese cell OEM which the Natron Energy collapse elevates to first-order importance; (c) treat the 6 red-line findings in Section 08 as triggers for reconsideration of scope or continuation of the partnership. On this basis, Langhus can proceed with the PowerCap partnership on a well-underwritten foundation. Without this framework, Langhus's US$143M European manufacturing commitment and its 14.104 GWh pipeline value would rest on PowerCap representations that have not been independently tested, and on the assumption that PowerCap's future capital events will succeed — an assumption that the 2025 Natron collapse warns should not be made without protective structuring.
