[Read on the website]() ## Issue 7 Samsung SDI reported KRW 80.5 billion in AMPC credits last quarter. You won't find that in the English investor deck. It sits in a KRX regulatory filing, in Korean, and it reframes the July 30 comparison: LGES looks more credit-dependent than Samsung partly because LGES actually shows the dependency. We kept running into that same dynamic all week, from Ford Kentucky's BESS pivot to lithium-indexed contracts that miss the iron phosphate cost moving against them. The risk right now lives in the layer between what gets filed and what gets presented. ### [Signal]() The numbers, their velocity, and what moves next - **Lithium Carbonate Decline Accelerates Past Seven Percent** — [Source]() — Published 2026-07-24 ▼ Meaningful WoW change. InfoLink July 22: RMB 141,000/MT average (139,000–143,000 range), down 7.2% WoW. Third consecutive acceleration: −2.6% (July 8), −5.0% (July 15), −7.2% now. SMM July 24 confirms continued drift. Downstream buying hand-to-mouth only. - **Spodumene SC6 Drops Nearly Seven Percent Weekly** — [Source]() — Published 2026-07-24 ▼ Meaningful WoW change. InfoLink July 22: $2,050/MT average ($2,000–$2,100 range), down 6.8% WoW. Tracking lithium carbonate in lockstep, pointing to supply-side repricing rather than isolated demand destruction. No secondary source available at this assessment date. - **ESS 280 Ah LFP Cell Holds Plateau** — [Source]() — Published 2026-07-24 ◆ Flat. InfoLink July 22: RMB 0.370/Wh, flat WoW. SMM July 24: $0.0475/Wh, +$0.0003 day-over-day. That SMM tick is sub-noise. Early-July cell softening has arrested even as lithium keeps falling underneath it. - **ESS 314 Ah LFP Cell Flat Both Sources** — [Source]() — Published 2026-07-24 ◆ Flat. InfoLink July 22: RMB 0.370/Wh, flat WoW. SMM July 24: $0.0478/Wh, flat. SMM's 314 Ah ESS Index at $0.0471/Wh shows −$0.0001 day-over-day, which is sub-noise. Both formats have converged to the same InfoLink average. - **DC-Side ESS System Pinned at Floor Level** — [Source]() — Published 2026-07-24 ◆ Flat. InfoLink July 22: RMB 0.50/Wh, flat WoW. This level has held since at least early July through cell moves in both directions. Non-cell costs (PCS, thermal management, fire suppression, EMS, warranty provisions) limit system-price sensitivity to raw-material swings. - **China EV LFP Cells: Marginal Upward Noise** — [Source]() — Published 2026-07-24 ~ Noise. SMM July 24: 100 Ah and 174 Ah formats both at $0.0515/Wh average, each +$0.0002 day-over-day. Cumulative drift of roughly +1.2% over two weeks from the July 10 baseline of $0.0509/Wh. Not a reversal signal. - **EV NMC Cells Flat Across Both Series** — [Source]() — Published 2026-07-24 ◆ Flat. SMM July 24: 5-series (50–60 Ah) at $0.081/Wh, flat. 6-series (144 Ah) at $0.0806/Wh, +$0.0003 day-over-day, within noise. NMC holds a ~57% premium over LFP at China domestic spot. - **Five MWh ESS Stack Price Unchanged Weekly** — [Source]() — Published 2026-07-24 ◆ Flat. SMM July 24: $0.0563/Wh average ($0.0538–$0.0589 range), flat. Sits above naked ESS cells but below InfoLink's DC-side containerized system price, capturing partial integration cost. Mirrors the broader downstream stillness. - [The Pass-Through Trap]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 · Format: The Velocity Synthesis Lithium carbonate posted its sharpest weekly decline of 2026 and LFP ESS cells registered zero pass-through. SMM's 280 Ah format ticked up. Three consecutive weeks of this pattern now have a mechanism: iron phosphate rose ~40% in H1, cathode processing fees increase August 1, and Q2 absorption tightened. The cost stack decoupled from its most-watched input sometime in H1, and any cell-price model still running lithium as the primary variable is already broken. Buyers planning to lever the carbonate decline into procurement concessions will find the other side of the table unmoved. - [The LFP Cost Floor That Lithium Indexation Misses]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 Iron phosphate rose from approximately RMB 10,000/MT at year-end 2025 to [RMB 14,500–15,000/MT by mid-July](https://news.metal.com/newscontent/104002063-smm-mid-year-market-analysis-2026-h1-lfp-cathode-material-market-review), per SMM's H1 LFP cathode review (July 13) and Hunan Yuneng's own client letter ([SMM, July 16](https://news.metal.com/newscontent/104008673-smm-lithium-battery-lfp-market-leader-announces-price-increase-all-series-to-raise-by-2000-yuanmt-from-august-1)).

GAC Aion [extended the warranty](https://cnevpost.com/2026/07/18/calb-in-spotlight-gac-aion-s-battery-cell-defects/) to 8 years/300,000 km. Only for Aion S. No formal recall filed. - [Three Filters, No Exits]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 · Format: The Structural Map Lithium carbonate fell 7.2% in a week. LFP ESS cells held flat. That decoupling is not noise. Three filters now active on overlapping timelines are sorting Chinese cell capacity into tiers of bankability: quality enforcement that closes the EV channel for producers who can't fund qualification, a staged fiscal squeeze through consumption tax and VAT rebate elimination, and contract-accountability requirements that make balance-sheet depth a pricing dimension in ESS procurement. None of these filters require a line to shut down. Provincial incentives keep nameplate intact. The generic China EXW spot and the bankable procurement price are separating into two different numbers, and the spread between them is widening from three directions at once. - [CATL's H1 2026 Margin Spread Is a Stratification Map]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 · Format: Leader Economics CATL's H1 2026 filing shows both segment gross margins falling while the spreads between them widened. Overseas margin rose to 29.97% as domestic compressed to 21.16%, pushing the geographic premium to 8.81 percentage points from 6.08 a year earlier. ESS held its premium over power battery. Utilization climbed to 94.86% on a capacity base 52% larger. This is selective pricing power exercised at near-full output while the cash position grows. The Tier-2 cohort is improving from distressed levels. It is not converging. - **GB38031 Live, MIIT Inspecting OEMs This Week** — [Source]() — Published 2026-07-24 GB38031-2025 effective July 1. Core change: thermal diffusion must produce no fire or explosion, replacing the prior five-minute escape window. MIIT sampled vehicles and batteries at GAC Aion and Xpeng on July 24 (People's Daily).

Q2 preliminary: KRW 113.3B reported operating profit, KRW 241.0B IRA credit contribution, implying a KRW -127.7B ex-credit operating loss (LG Energy Solution IR release). That loss narrowed substantially from approximately KRW -397.5B in Q1. Reported profit turned positive solely because the credit exceeded the underlying shortfall. Full decomposition holds for the July 30 final release. - **Samsung SDI's KRX Filing Surfaces AMPC Figure** — [Source]() — Published 2026-07-24 Q1 battery-segment revenue KRW 3.35T, operating loss KRW -176.6B (Samsung SDI Q1 2026 earnings release). The English IR deck omitted any 45X breakout. The KRX preliminary filing, however, disclosed KRW 80.5B in consolidated AMPC. See the companion feature for the full subsidized-economics decomposition; this card is status only. - **SK On Loss Narrows, Credit Disclosure Still Absent** — [Source]() — Published 2026-07-24 Q1 revenue KRW 1.79T, operating loss KRW -349.2B, improved from KRW -440.8B in Q4 (SK Innovation Q1 2026 consolidated earnings). Europe and Asia volume recovery partially offset softer North American shipments. No 45X or AMPC figure appeared in reviewed filings. The GRIDON ESS roadmap carries no named customer and no delivery evidence to date. - **July 30: All Three Report the Same Day** — [Source]() — Published 2026-07-24 LGES at 10:00 KST, Samsung SDI at 14:00, SK Innovation at 16:00 (KRX IR schedule filings). Six hours, three calls. This is the next hard data drop for Q2 utilization direction, ASP trajectory, EV versus ESS revenue mix, and facility-level production detail. None of these signals are publicly available before that date. - **Lithium Fell, Chinese ESS Cell Prices Didn't** — [Source]() — Published 2026-07-24 InfoLink assessment, July 22: lithium carbonate dropped 7.2% WoW to roughly RMB 141K/MT, yet LFP ESS cells held at RMB 0.370/Wh and DC containers at RMB 0.50/Wh. Fourth consecutive week of cell-lithium divergence. The competitive floor Korean ESS routes price against did not budge. - **No Fresh Utilization Data From Any Korean Maker** — [Source]() — Published 2026-07-24 No Q1 or Q2 2026 utilization rate was disclosed by any of the three companies in reviewed filings. Standing baselines are 2025 annual figures: LGES 47.6%, Samsung SDI approximately 50%, SK On 48.7%. Presenting these as current would be misleading. July 30 calls are the next opportunity for a refresh. - [Samsung SDI Q1 2026: Ex-Credit Losses Narrowed, but the Battery Segment Bridge Stays Blank]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 · Format: The Earnings Decomposition Samsung SDI's consolidated ex-credit operating loss narrowed to KRW -236.1B in Q1 2026, improving KRW 374.7B from the Q3 2025 trough on essentially flat AMPC. The improvement is operational, not credit-driven. But the KRW 80.5B in disclosed production incentives sits at the consolidated level. Samsung does not allocate it to the battery segment, which means the segment-level credit bridge that LGES now provides quarter by quarter remains a blank row. Direction is improving. Legibility of that improvement has not kept pace. - [The Samsung SDI–L&F cathode deal reads differently in KRX than in the press release]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 Samsung SDI's [March 2026 announcement](https://www.samsungsdi.com/sdi-now/sdi-news/4822.html) frames the L&F agreement as a "mid- to long-term LFP cathode supply deal" worth "approximately KRW 1.6 trillion over three years starting next year." The pricing mechanism, volume flexibility, and conditionality are all absent. Read cold, it sounds like locked supply for StarPlus ESS production. - **Samsung SDI Q1 2026 Earnings Release (English)** — [Source]() — Published 2026-07-24 Battery-segment KRW 3.35T revenue and KRW -176.6B operating loss; credits AMPC for the sequential improvement but does not quantify the credit, which is the gap the KRX filing fills. - **KRX Samsung SDI Q1 2026 Preliminary Consolidated Results** — [Source]() — Published 2026-07-24 Contains the KRW 80.5B AMPC/45X figure absent from the English deck, making it the primary source for the ex-credit operating loss derivation (KRW -257.1B) central to this issue's 45X decomposition. - **Samsung SDI Announces L&F LFP Cathode Supply Deal** — [Source]() — Published 2026-07-24 The press-release version of the KRW 1.6T cathode deal: StarPlus Indiana delivery, Q4 2026 LFP mass-production target, and PFE-compliance framing worth reading against the contractual fine print in the L&F KRX filing below. - **L&F KRX Contract Filing for Samsung SDI LFP Cathode Supply** — [Source]() — Published 2026-07-24 The contractual terms the press release omits: ±25% annual volume variance, raw-material price linkage, and a supply-suspension clause triggered by pricing disputes, all of which qualify the headline commitment significantly. - **Samsung SDI Wins KRW 1.5 Trillion U.S. ESS Prismatic Battery Deal** — [Source]() — Published 2026-07-24 NCA-to-LFP phased supply through StarPlus (2026–2029) with an unnamed U.S. energy counterparty and no GWh volume disclosed, making independent verification of implied ASP and capacity commitment impossible from this source alone. - **Samsung SDI Q2 2026 IR Schedule Disclosure** — [Source]() — Published 2026-07-24 Confirms the July 30 earnings call at 14:00 KST with simultaneous English webcast; no Q2 financials are available before that date, which bounds what this issue can and cannot assess. ### [The Log]() What was announced, built, and cancelled - [Four US BESS facilities are quoting 2027–2028 delivery. None has shipped a cell.]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 Four US facilities are quoting domestic BESS cell delivery for 2027–2028. None has publicly demonstrated shipped product, customer acceptance, or compliance documentation that would support a bankable offtake. [Ford Energy](https://fordauthority.com/2026/05/ford-energy-takes-full-control-of-kentucky-battery-plant/) quotes 20 GWh/year of LFP containerized systems from Glendale, Kentucky starting late 2027, with an [EDF offtake](https://www.energy-storage.news/ford-officially-launches-us-stationary-energy-storage-subsidiary-deliveries-to-begin-in-2027/) already signed. No trial production at Glendale has been disclosed. Ford's CATL technology license adds an unresolved PFE question the company addresses only as an "[expectation](https://www.energy-storage.news/ford-officially-launches-us-stationary-energy-storage-subsidiary-deliveries-to-begin-in-2027/)" of compliance. StarPlus Energy has the clearest operational milestone here: [NCA ESS production confirmed October 2025](https://www.samsungsdi.com/sdi-now/sdi-news/4802.html) via Samsung SDI financials. Its LFP conversion targets Q4 2026 per [company guidance](https://samsungsdi.com/sdi-now/sdi-news/4822.html), unconfirmed as achieved.

It also has a DOE project page still describing EV batteries for a JV entity that no longer exists, no cell-line equipment confirmation from any major supplier, and zero public 45X, MACR, or PFE disclosure. The retooling is traceable. The production is not. Anyone placing 20 GWh of domestic BESS cell supply from this facility into a 2027–2028 model should know precisely which evidence layers exist and which are absent. - [US BESS Conversion Registry: Seven Rungs, Five Facilities, One Operating Line]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 · Format: Conversion Landscape One converted NCA ESS line at one facility, trade-reported at approximately 7 GWh. No BESS cells publicly evidenced as shipped to any buyer, anywhere in the domestic pipeline. This registry maps five US battery plants carrying BESS conversion language against seven proof rungs for contractable output. The $4.3 billion Tesla-LGES deal at Lansing, the strongest customer agreement in the set, has no disclosed cathode source. SK Commerce is still "pursuing" customers five months after a WARN filing. Input sourcing is the systematic gap. Where cathode supply is unresolved, stated timelines are aspirational until demonstrated otherwise. - [Three Layers, Zero Public Proof: The Documentation Void Behind Converted BESS Compliance Claims]() — By [Elise Huan-Cartwright]() · Published 2026-07-24 · Format: Compliance Filter Converted U.S. battery facilities are selling BESS output as domestic, compliant, and credit-eligible. Those claims must clear three independent regulatory layers: 45X manufacturing credits, MACR/PFE substantiation under IRS Notice 2026-15, and FEOC restrictions. As of July 24, 2026, no converted facility has publicly demonstrated clearance through all three. The documentation architecture exists on paper.

Two adjacent regimes published waiver requirements in June and July: Section 805's intake site went live June 30, and the July 20 executive order imposed mitigation-plan demands on 4872 specialty-metal waivers. Both treat nonavailability as a condition to be proven, not asserted. Map their procedural demands onto batteries and the requirement becomes component-level cost-origin documentation across eight functional-cell-component categories, each traced to FEOC or non-FEOC origin. No public supplier has demonstrated the ability to produce that documentation. - [Four Defense Battery Suppliers Against the Section 4865 Proof Ladder]() — By [Ronan Adike]() · Published 2026-07-24 · Format: Proof Ladder Four companies show public evidence of positioning for the Section 4865 defense battery market: Packet Digital, Forge Nano/Samsung SDI, EnerSys/Bren-Tronics, and Ultralife. We mapped each against four compliance dimensions and labeled every claim by source tier. Cost-origin proof is blank across all four. QPL-32565 lists zero qualified products from any manufacturer. The qualification infrastructure and the supplier base are developing on independent timelines, and neither is close to done. Eighteen months from the January 2028 new-program deadline, the ladder has rungs but no top. - **Section 4865 Deadlines Running, No Public DFARS** — [Source]() — Published 2026-07-24 FEOC battery restrictions hit new acquisitions January 1, 2028. Standard batteries January 1, 2029. Existing programs January 30, 2031. The 95% non-FEOC cost-origin threshold applies to all three tranches. Statutory 180-day DFARS revision deadline passed June 16. No implementing clause found in checked public routes as of July 17. - **Section 805 Direct Ban Live, Waiver Portal Open** — [Source]() — Published 2026-07-24 DoD launched a public Section 805 compliance website June 30, banning direct procurement from 1260H-listed Chinese military companies. Indirect supply-chain ban follows June 30, 2027. Waiver intake requires compelling justification, market analysis, and phased removal milestones. The only live public waiver machinery in DoD right now. - **July 20 EO Builds Waiver Gates on 4872** — [Source]() — Published 2026-07-24 Executive order signed July 20 targets 10 U.S.C. 4872 covered materials. Not batteries directly, but adjacent. From January 1, 2027, waivers require formal mitigation plans: identification of noncompliant sources, documented qualification efforts, strict removal timelines. Indentured BOM tracing to raw-material origin due within 180 days. Read this as a signal for where Section 4865 waiver architecture will land. - **Blue List Adds Two, Still No Battery Fields** — [Source]() — Published 2026-07-24 DCMA Blue List endpoint shows 71 public UAV rows as of July 24, up from 69 on July 17. Additions: Skydio R10 and X10. Twenty-one Select rows. Exposed fields: platform name, manufacturer, certification status. No battery supplier, cell chemistry, cost-origin, or FEOC compliance fields visible. Platform certification is not component-level compliance. - **MIL-PRF-32565 Active, QPL Shows Zero Qualified Products** — [Source]() — Published 2026-07-24 MIL-PRF-32565 active, data current July 23. Next review August 2027. QPL-32565 active but lists no established products or sources in checked public record. Army SBIR topic A254-P050 closed May 2026 for Phase I Li-ion 6T thermal-runaway work. Awards to Farad Power, Nanotech Energy, and CAMX Power are Phase I R&D, not production commitment. - **Federal Register Returns Zero on Section 4865 Battery** — [Source]() — Published 2026-07-24 Federal Register API queries for "10 USC 4865" and "section 4865 advanced batteries" filtered to Defense Department return zero results. Acquisition.gov DFARS search surfaces no advanced-battery clause. The statutory implementation deadline passed five weeks ago. Bounded finding: no visible public artifact in checked routes. Not proof of internal inaction. - **Adjacent Waiver Lanes Running, Battery Lane Still Dark** — [Source]() — Published 2026-07-24 Section 805 has a live portal with forms, email intake, and structured justification requirements. The July 20 EO builds mitigation-plan gates for 4872 waivers starting January 2027. Section 4865 waiver authority exists in statute but has no public template, FAQ, or operational form in any checked route. The Section 836 compliance repository is due January 1, 2027. - **Trump Executive Order Tightens Defense Supply Chain Waiver Rules, Demands Documented Alternatives** — [Source]() — Published 2026-07-24 Contractors must now file phase-out plans. Navarro framing signals waiver scrutiny will extend to battery sourcing. - **DoD Launches Section 805 Compliance Website with Central Hub and Waiver Contact** — [Source]() — Published 2026-07-24 Dual-timeline structure, public waiver email. Section 4865 battery rules have no equivalent infrastructure yet. - **Hegseth Drone-Dominance Memo Transfers Blue List to DCMA with 71 UAV Rows** — [Source]() — Published 2026-07-24 DCMA now operates the cleared list.

Directional for how battery waivers will be conditioned. - **DFARS Change Notices Through July 2026: PCB and Specialty Metal Rules Advancing, Battery Clause Absent** — [Source]() — Published 2026-07-24 No Section 4865 ANPR or proposed rule visible. The rulemaking gap widens as the 2028 deadline holds. ### [Qualification]() Pack-level requirements, test conditions, and standards by application - [eVTOL / Powered-Lift Pack Qualification Standards Map]() — By [Ronan Adike]() · Published 2026-07-24 · Format: The Standards Map Eleven parameter classes matter for eVTOL propulsion-pack qualification. One is settled. Four have test frameworks but no assigned severity levels. Four more, energy density, C-rate capability, cycle life, calendar life, carry no public threshold at all. Every DVP row in those classes gets closed by the applicant's own engineering analysis, accepted on a program-specific basis by the certifying authority. Not by a standard. This card maps the full layered structure across FAA AC 21.17-4, EASA MOC VTOL.2440, DO-311A, and DO-160G: what each document actually covers, where each one's scope terminates, and where the DVP is working without a net. - **MOC-3 Layers Propulsion Tests Over DO-311A Baseline** — [Source]() — Published 2026-07-24 EASA MOC-3 SC-VTOL Issue 2 (enhanced category). DO-311A §2.4.5.5 containment test was not developed for propulsion batteries; EASA acknowledges this explicitly. Two evidence paths: non-propagation (stabilization at 55°C, ≥8 hr monitoring) or continued-safe-flight containment (≥20% of cells driven into thermal runaway). Test definition requires EASA coordination on a per-program basis. Last verified 2026-07-17. - **Installed ESS Drop: 15.2 m, Non-Deforming Surface** — [Source]() — Published 2026-07-24 EASA MOC VTOL.2325(a)(4). Drop height ≥15.2 m onto non-deforming surface, ESS in most critical expected crash condition. Post-drop acceptance: fire or harmful leakage contained ≥15 minutes outside evacuation path. Scope: installed-ESS criterion, not standalone pack drop. Last verified 2026-07-17. - **Five Ultimate Load Factors for Cabin-Installed ESS** — [Source]() — Published 2026-07-24 EASA MOC VTOL.2325(a)(4), cabin ESS. Ultimate inertial load factors: 4g upward, 16g forward (18g for CTOL configurations), 8g sideward, 20g downward, 1.5g rearward. These are aircraft-installed criteria under SC-VTOL, not generic pack enclosure structural requirements. Last verified 2026-07-24. - **AC 21.17-4 Sets Aircraft-Level Energy System Objectives** — [Source]() — Published 2026-07-24 FAA AC 21.17-4 (issued 2025-07-18), PL.2430. Five criteria: energy provision, usable energy display to flightcrew, safe energy removal/isolation, energy retention under likely operating conditions, post-crash hazard minimization. All performance-based, all aircraft-level. No pack-level C-rate, cycle-life, or abuse test matrix published. Last verified 2026-07-24. - **DO-311A Alone Cannot Close Propulsion-Pack Acceptance** — [Source]() — Published 2026-07-24 MOC-4 SC-VTOL Issue 2 (final, 2025-07-11): accepts DO-311A or ETSO C-179b only when aircraft-level risk assessment and hazard controls are layered on top. MOC-5 Issue 1 remains post-consultation, not final (consultation closed 2025-10-10). Propulsion-pack acceptance requires the full MOC stack, not a single document. Last verified 2026-07-17. - **ASTM F3830-26 Governs Light-Sport ESS Only** — [Source]() — Published 2026-07-24 ASTM F3830-26 (active June 2026). FAA accepts it as consensus standard for electrical ESS under Part 22, light-sport category aircraft. It does not govern powered-lift or eVTOL programs certifying under AC 21.17-4 or EASA SC-VTOL. Applying F3830-26 to those programs is a category error. Last verified 2026-07-16. - **No Standard Governs eVTOL C-Rate Requirements** — [Source]() — Published 2026-07-24 Gap. No governing standard exists. Yang et al. (Joule, 2021) provides the most-cited analysis: hover/takeoff 2.5–4.5C, cruise 0.75–1.5C, peak-power bursts 30–120 s. Assumes 200 Wh/kg (gravimetric) pack, battery weight fraction 0.3. C-rates climb at lower specific energy. DVP must derive values from actual vehicle duty cycle. Last verified 2026-07-24. - **Cycle Life Remains Program-Defined, No Standard** — [Source]() — Published 2026-07-24 Gap. No governing standard. Yang et al. (Joule, 2021) estimates ~1,600 equivalent full cycles per year at high utilization. The 20% capacity-fade EOL criterion borrowed from EV programs does not transfer: power fade and reserve energy retention govern landing hover and balked-landing margins. DVP must specify EOL criterion, DOD, charge rate, and test temperature independently.

Lithium plating was the dominant degradation mode at propulsion-grade C-rates. Published Feb 2024 in ACS Energy Letters (open access, PMCID: PMC10928709). Tier 3 source. - **Safety Assessment for Battery Thermal Runaway Propagation for Urban Air Mobility** — [Source]() — Published 2026-07-24 TU Munich applies EASA MOC3 SC-VTOL as the governing TRP compliance framework for manned eVTOL, using fault tree analysis per SAE ARP4761. Cell-to-cell non-propagation alone fails manned safety targets. Thermal barrier mass penalties reach 17.3% of pack mass. - **Safety Design of Aviation Propulsion Lithium-Ion Battery Systems Based on Thermal Runaway Explosion Index** — [Source]() — Published 2026-07-24 Civil Aviation University of China proposes a composite Thermal Runaway Explosion Index (TREI) integrating inherent hazard, operational conditions, and protective design. Covers four DVP-relevant environmental stressors: low temperature (to −15°C), low pressure (70 kPa at 3,000 m), high-rate discharge, and vibration. - **Novel Battery Power Capability Assessment for Improved eVTOL Aircraft Landing** — [Source]() — Published 2026-07-24 University of Warwick defines a method for setting the minimum usable SOC threshold below which voltage sag compromises power delivery during eVTOL landing. No governing standard addresses this parameter. The paper provides a documented methodology for a program-defined reserve-energy DVP call. - [DO-311A is not your eVTOL propulsion pack qualification]() — By [Ronan Adike]() · Published 2026-07-24 EASA says it plainly. DO-311A §2.4.5.5's thermal runaway containment test "was developed for lithium batteries that provide power to other aircraft systems or equipment" — not propulsion batteries ([MOC VTOL.2440 §1](https://www.easa.europa.eu/en/document-library/easy-access-rules/online-publications/easy-access-rules-small-category-vca?page=17)). Citing it alone in a propulsion pack DVP misrepresents the regulatory posture. - **FAA AC 21.17-4: Type Certification Procedures for Powered-Lift Aircraft (July 2025)** — [Source]() — Published 2026-07-24 Sets aircraft-level energy system functional objectives that pack-level DVP test evidence must trace to for U.S. type certification. - **EASA SC-VTOL and Means of Compliance (MOC-4 Issue 2, MOC-5 consultation)** — [Source]() — Published 2026-07-24 Gateway to the MOC document family governing EASA's battery certification layers, including MOC-4 Issue 2 and MOC-5 draft status. - **EASA Easy Access Rules for Small-Category VCA: MOC VTOL.2440 and MOC VTOL.2325(a)(4)** — [Source]() — Published 2026-07-24 Covers the strongest public pack-level parameters: thermal runaway propagation limits, 15.2 m drop test, and installed ESS inertial load factors. - **ASTM F3830-26: Propulsion Battery ESS Qualification for Light Sport Aircraft (June 2026)** — [Source]() — Published 2026-07-24 Newest aviation propulsion-battery standard published, though scoped to light-sport category and not directly applicable to powered-lift eVTOL pathways. - **RTCA DO-311A: MOPS for Aircraft-Installed Rechargeable Lithium Batteries (Dec 2017)** — [Source]() — Published 2026-07-24 Referenced by FAA TSO-C179b and EASA MOC-4 for baseline safety tests, but scope explicitly excludes large propulsion battery systems. ## More - [Publication guide]() - [Issue archive]()
