Success means the team consistently identifies inflection points in cell pricing, supplier health, and policy enforcement weeks or months before they surface in earnings calls, annual surveys, or trade press. The commercial mechanism is internal-first: the publication proves itself as a decision tool inside the organization, then extends to paid subscribers and a practitioner community as upside. Revenue follows utility — if the team makes better-timed procurement calls and competitive assessments because of what they read here, the publication earned its place. [Read on the website]() ## Issue 8 We spent this week trying to verify things. All three Korean cell makers reported Q2 improvement. Only one disclosed enough for us to decompose the result to an ex-credit number. That gap between reported and provable kept showing up: in Chinese export growth heading into a narrowing corridor of tax changes and equipment restrictions, in a US cancellation count where a bankrupt facility and a converted production line register as the same event. The number always exists. Whether you can build a sourcing decision on it is what this issue works through. ### [Signal]() The numbers, their velocity, and what moves next - **InfoLink Lithium Reverses, Up 2.1% After Drop** — [Source]() — Published 2026-07-31 Battery-grade carbonate at RMB 144,000/MT average on 29 July, +2.1% WoW (InfoLink). Prior week was -7.2%. Restocking around RMB 140,000 and stronger planned cell production schedules cited as support. Velocity: directional reversal inside two weeks, second derivative flipping positive. - **SMM Lithium Points Down, Contradicts InfoLink Direction** — [Source]() — Published 2026-07-31 SMM battery-grade carbonate at RMB 143,000/MT on 31 July, -2.05% from RMB 145,500 on 24 July. CIF CJK at $18,580/ton. Two-day timing gap with InfoLink partially explains the opposing prints, but the trajectory disagreement is genuine. Velocity: still declining on the SMM tape. - **InfoLink ESS Cells Crack Below RMB 0.370 Floor** — [Source]() — Published 2026-07-31 280Ah and 314Ah LFP cells at RMB 0.360/Wh on 29 July, -2.7% WoW (InfoLink). First print below RMB 0.370 in the current series. Attributed to selective concessions on large-customer Q4 orders, not broad repricing. Velocity: new floor, accelerating on the downside. - **SMM ESS Flat, No Confirmation of InfoLink Break** — [Source]() — Published 2026-07-31 SMM 314Ah LFP at RMB 0.367/Wh on 31 July, flat. 280Ah at RMB 0.367, up RMB 0.002. That leaves a RMB 0.007 gap versus InfoLink's 0.360. Likely reflects different counterparty classes; concessions show up in key-account pricing before the broad tape moves. Velocity: stable on SMM, watch for lag confirmation. - **EV Cells Firm While ESS Slides Since July** — [Source]() — Published 2026-07-31 SMM EV readings on 31 July: LFP prismatic $52.10–$52.40/kWh, +2.4–2.9% from 10 July. NMC ternary $81.50–$94.00/kWh, +2.2–2.5%. Positive across all formats over the 21-day window. Application-level demand dynamics are overriding shared input costs. Velocity: gradual firming, opposite direction to ESS. - **DC System Price Breaks Four Weeks of Flat** — [Source]() — Published 2026-07-31 InfoLink DC 2-hour liquid-cooled system at RMB 0.490/Wh on 29 July, -1.0% WoW after four consecutive flat prints at RMB 0.500. AC systems unchanged across all durations. Cell-level concession pass-through running at roughly one-third pace. Velocity: first move in a month, shallow. - **Huaneng Four-Hour Tender Clears at Aggressive Low** — [Source]() — Published 2026-07-31 Guangzhou Zhiguang Storage won the Huaneng Ningxia 80MW/320MWh four-hour award at RMB 0.497/Wh, roughly 15% below competing bids of RMB 0.560–0.590. Near the Huadian 12GWh framework floor. Scope and warranty terms undisclosed. Read this as supplier behavior, not market clearing. Velocity: floor-testing bid, isolated. - [Cells Conceded RMB0.010/Wh; Carbonate Rose the Same Week]() — By [Elise Huan-Cartwright]() · Published 2026-07-31 · Format: The Velocity Synthesis InfoLink's 280/314Ah ESS-cell average came off the RMB0.370/Wh plateau this week, 2.7% WoW to RMB0.360. In the same assessment, the same house marked battery-grade carbonate up 2.1%. SMM's Friday tape did not follow, and EV prismatic printed the other way entirely. - [Only One Korean Q2 Profit Survives Without 45X]() — By [Elise Huan-Cartwright]() · Published 2026-07-31 All three Korean cell makers posted operating profit in Q2 2026. Ranked by headline: SK On KRW821.8B, Samsung SDI KRW203.8B, LGES KRW113.3B. Net of the US 45X production credit the ranking doesn't hold — and for one of the three it can't be recomputed at all. - **InfoLink and SMM Diverge on Late-July ESS Cell Pricing** — [Source]() — Published 2026-07-31 Two benchmark sources disagree on direction. Procurement teams pricing Q4 need to know which to weight. - **LGES Q2: Operating Profit Returns, but the Ex-Credit Bridge Stays Negative at KRW 128B** — [Source]() — Published 2026-07-31 ESS revenue quadrupled YoY. Inventory climbed KRW 1.1T. Strip out 45X and the loss persists. - **Samsung SDI Posts First Profit in Seven Quarters; Battery-Segment Ex-AMPC Bridge Still Undisclosed** — [Source]() — Published 2026-07-31 Consolidated ex-AMPC profit ~KRW 96B per Korean press. Segment-level detail remains a gap in English IR. - **SK On Reports KRW 822B Profit, but One-Offs and AMPC Make the Recurring Base Opaque** — [Source]() — Published 2026-07-31 BlueOval SK unwinding saves ~KRW 500B/year. Customer comp and AMPC magnitude still unquantified. - **FCC Blocks New Foreign-Produced Connected Inverters From US Market** — [Source]() — Published 2026-07-31 Previously authorized models unaffected. New BESS configurations now face authorization barrier or federal review. - **Korean Press Fills Samsung SDI's AMPC Disclosure Gap: KRW 107.7B in Q2** — [Source]() — Published 2026-07-31 Seoul Economic Daily reports the figure English IR omits. A recurring pattern across all three Korean makers. ### [China]() CATL, BYD, and the market that sets the floor - [The FCC Gate Sits at the Inverter]() — By [Ronan Adike]() · Published 2026-07-31 On 28 July the FCC added foreign-produced connected power inverters to its Covered List, acting on an interagency national security determination issued the day before ([FCC notice](https://www.fcc.gov/document/fcc-adds-foreign-produced-power-inverters-and-robots-covered-list-0)). - [Ten Points Came Off the Export Stack in July. January 1 Reprices It]() — By [Elise Huan-Cartwright]() · Published 2026-07-31 · Format: The Structural Map Section 122's 10% surcharge lapsed 24 July, no extension in the record. Chinese-origin cells under HTS 8507.60.00 now carry a combined 28.4% ad valorem, ten points below where most 2026 landed-cost models still sit. On a grid-scale project claiming 48E that relief is worth nothing. On one that isn't, it is worth all ten points. And 10 November controls winding and formation equipment, not sub-200 Wh/kg storage cells. Four dated events reprice the export stack before January. Three are commonly misread. The most-watched is misread worst. - [CATL's Overseas Premium Nearly Doubled in Two Years. The Overseas Line Moved 0.32 Points.]() — By [Elise Huan-Cartwright]() · Published 2026-07-31 · Format: CATL Export Economics CATL's H1 2026 interim puts overseas gross margin at 29.97% against 21.16% at home. Two years ago that gap was 4.47 points. It is now 8.81, and almost the entire widening came out of the domestic line falling. Overseas moved 0.32 points across matched halves. - **Lithium Carbonate Bounces After Two Weeks Down** — [Source]() — Published 2026-07-31 InfoLink assessed battery-grade lithium carbonate at RMB 144,000/MT on 29 July, +2.1% WoW. Breaks a two-week slide of -5.0% and -7.2%, but still 10% below the 8 July local peak. SMM flagged buyer resistance and just-in-time procurement. Read this as a supply-side dead-cat bounce, not demand pull. - **ESS Cells Break Plateau With Selective Concessions** — [Source]() — Published 2026-07-31 InfoLink's 280/314 Ah LFP ESS cell average fell to RMB 0.360/Wh on 29 July, -2.7% WoW. First move after three flat weeks at RMB 0.370/Wh. The concessions are targeted: preferential pricing for major buyers locking Q4 volumes, not a universal clearing price. Tier-2 producers are likely offering steeper discounts off-index. - **AC System Prices Absorb Cell Drop, Hold Flat** — [Source]() — Published 2026-07-31 InfoLink's 2-hour DC liquid-cooled container edged -1.0% to RMB 0.49/Wh. All three AC-system durations (1h, 2h, 4h) unchanged. PCS, thermal management, fire protection, and commissioning costs eat cell-level concessions before they reach the buyable system. Cell price is not system price. - **H1 Production Growth Runs Four Times Installation Growth** — [Source]() — Published 2026-07-31 CABIA data via CnEVPost: H1 combined production +53.3% YoY versus domestic power-battery installations +12.0% YoY. ESS sales (+83.4%) and exports (+42.5%) absorbed the difference. SMM reported industry-wide utilization near 80%, with smaller producers still order-constrained. The overcapacity is real but unevenly distributed. - **CATL Utilization Hits 95% While Industry Averages 80%** — [Source]() — Published 2026-07-31 CATL H1 2026 filing: 94.86% battery-system utilization on 525 GWh capacity, up from 89.86% in H1 2025. Revenue RMB 276.9B (+54.8% YoY). Overseas gross margin 29.97% vs. 21.16% domestic. Cash and trading financial assets at RMB 440.2B. That 15-point utilization gap between CATL and the industry average is the overcapacity story in one number. - **MIIT Inspections Reach Five OEMs in Four Weeks** — [Source]() — Published 2026-07-31 GB 38031-2025 took effect 1 July for new-model type approval. MIIT inspected GAC Aion and Xpeng on 24 July (Xinhua confirmed). TechTimes reported a second wave today at Chery, NIO, and JAC. No test results, failed approvals, or supplier disqualifications in the public record yet. Enforcement pace is real; enforcement consequences remain invisible. - **Battery Consumption Tax Live in Thirty-One Days** — [Source]() — Published 2026-07-31 MOF Announcement No. 20: 2% consumption tax on lithium-ion batteries from 1 September 2026, rising to 4% on 1 September 2027. Sodium-ion and solid-state exempt through 31 December 2028. Export consumption-tax exemption unchanged. Valuation guidance for integrated ESS products still unpublished. Without it, tax basis on bundled systems remains ambiguous. - **Export Control Suspension Expires in 102 Days** — [Source]() — Published 2026-07-31 MOFCOM's suspension of Announcement No. 58 export controls expires 10 November 2026. Covers cells ≥300 Wh/kg, key manufacturing equipment, and artificial graphite anode materials. No public notice modifying or extending the suspension found through MOFCOM's 24 July announcement index. VAT export rebate drops to zero on 1 January 2027, 154 days out. - **CATL H1 2026: Overseas Margin Holds at ~30% While Domestic Compresses to ~21%** — [Source]() — Published 2026-07-31 The 8.8-point overseas-domestic gap is the internationalization premium. ESS now nearly 20% of revenue, up 88% YoY. - **CATL's Per-Wh Gross Profit Drops to ~RMB 0.15 in Q2, Below Street Expectations** — [Source]() — Published 2026-07-31 Net profit per Wh fell to RMB 0.097. The trajectory matters: margin compression is accelerating even at 90%+ utilization. - **China Customs Data Through April 2026: EU Takes 41% of Li-Ion Export Value, US Just 9%** — [Source]() — Published 2026-07-31 The destination split quantifies where tariff and trade-route risk actually concentrates. EU exposure dominates. - **FCC Inverter Ban Effective July 28: Scope Limited to Networked Units, Air-Gapped Excluded** — [Source]() — Published 2026-07-31 The networked-vs-hardwired distinction narrows real operational impact. Relevant for BESS integration sourcing decisions. - **New Li-Ion Consumption Tax: Goldman Estimates 1–6% Profit Hit for CATL, Up to 55% for Tier-2** — [Source]() — Published 2026-07-31 The asymmetry is the signal. This is a regulatory consolidation mechanism where the market's own pricing hasn't delivered one. - **MOFCOM Adds 14 EU Entities to Export Control Watchlist After Sanctions Escalation** — [Source]() — Published 2026-07-31 Not battery-specific, but signals MOFCOM's expanding use of export controls as leverage. Watch the graphite regime. ### [Korea]() LG, Samsung, SK — beyond the headlines - **LGES Swings to KRW 113.3B Operating Profit** — [Source]() — Published 2026-07-31 Verified. Q2 operating profit KRW 113.3 billion, reversing Q1's KRW 207.8 billion loss. EBITDA KRW 1.330 trillion. H1 ESS revenue grew 4.6x YoY per the IR deck. No GWh shipment volume disclosed for either segment. - **LGES Discloses Ex-Credit Loss: KRW -127.7B** — [Source]() — Published 2026-07-31 Verified. Company-disclosed, not arithmetic. KRW 241.0 billion in North American production incentives stripped out yields an ex-credit operating loss of KRW 127.7 billion. Improved KRW 269.9 billion QoQ from Q1's ex-credit result. The only complete 45X bridge filed by any of the three. - **Samsung SDI Profits After Seven Consecutive Loss Quarters** — [Source]() — Published 2026-07-31 Verified. Consolidated operating profit KRW 204 billion; battery segment KRW 159 billion. Management cited product mix, AMPC, tariff effects, and UPS/BBU demand. Note: H1 net profit of KRW 527.7 billion includes KRW 402 billion in non-recurring affiliate equity income. - **Samsung SDI AMPC Absent From English Disclosure** — [Source]() — Published 2026-07-31 Not verifiable. Q2 English IR deck names AMPC as a profit driver but withholds the figure. Q1 KRX filing showed KRW 80.5 billion consolidated; Q2 KRX filing has not been reviewed. Battery-segment AMPC allocation is never broken out. Ex-credit profit cannot be derived. - **SK On Posts KRW 821.8B Operating Profit** — [Source]() — Published 2026-07-31 Verified. Revenue KRW 2.946 trillion, up 57% QoQ. Operating profit swung KRW 1.171 trillion from Q1's loss. Management cited expanded Asian sales, a one-off customer compensation payment, and higher AMPC. An AMPC revenue reclassification complicates QoQ comparison. - **SK On Recurring Profit Unverifiable From Filings** — [Source]() — Published 2026-07-31 Not calculable. Neither the customer compensation amount nor AMPC is quantified in public materials. The BOSK JV exit saves an estimated KRW 500 billion annually starting H2 2026, a real structural improvement. But Q2 recurring operating performance remains opaque. - **LGES Cash Conversion Collapsed on Inventory Build** — [Source]() — Published 2026-07-31 Verified. Operating cash flow: KRW 25 billion against KRW 1.330 trillion EBITDA. Working-capital outflow of KRW 1.185 trillion absorbed nearly everything, driven by a KRW 1.091 trillion inventory build. Whether that inventory is ESS commissioning stock or unsold cells is undisclosed. - **Utilization and ASP Dark Across All Three** — [Source]() — Published 2026-07-31 Gap across all three makers. No Q2 utilization rate, cell ASP, or $/kWh realization appears in any July 30 filing. Last public baselines: LGES 47.6%, Samsung SDI 50.0%, SK On 48.7% (2025 annual figures). Whether Q2 profits reflect price stabilization or volume mix remains unverifiable. - [Only One of the Three Korean Q2 Improvements Is a Number You Can Use]() — By [Elise Huan-Cartwright]() · Published 2026-07-31 · Format: The Earnings Decomposition All three Korean cell makers reported sequential improvement on July 30, and the three improvements are not the same class of quantity. LGES set KRW 241.0B of North American incentives against KRW 113.3B of reported operating profit: a point estimate, and an underlying loss of KRW 127.7B. Samsung SDI disclosed KRW 107.7B of AMPC at the consolidated layer, one level above the battery segment a buyer actually contracts with, which yields a ceiling and no floor. SK On's KRW 821.8B reversal contains three unquantified inputs, leaving the sign of recurring profit open. None of the three disclosed a 2026 utilization rate. - [Three StarPlus LFP Dates, No Commissioning Milestone]() — By [Elise Huan-Cartwright]() · Published 2026-07-31 Samsung SDI's [March 24 release](https://www.samsungsdi.com/sdi-now/sdi-news/4822.html) says StarPlus "is expected to mass-produce" LFP from Q4 2026 — facility-level, conditional, no GWh threshold attached. [ETNews on July 6](https://en.etnews.com/20260706200004), citing unnamed industry sources, puts the first LFP line's production start at September, ahead of Samsung's own target. The June 25 ETNews report puts LFP equipment installation completion in H1 2027, expanded supply from H2. - **Samsung SDI Discloses KRW 107.7B AMPC — and Claims Profitability Without It** — [Source]() — Published 2026-07-31 Resolves the key disclosure gap this cycle. Ex-subsidy KRW 96.1B profit sets Samsung SDI apart from LGES. - **SK On Posts Record Quarterly Profit as BlueOval SK Dissolution Completes** — [Source]() — Published 2026-07-31 KRW 821.8B operating profit includes undisclosed one-time gains. Separate the structural from the transactional before citing this number. - **SK Innovation Earnings Call: BlueOval Savings Quantified, AMPC Still Dark** — [Source]() — Published 2026-07-31 KRW 500B annual fixed-cost relief confirmed. Q2 AMPC and Ford compensation amounts remain undisclosed. The 45X gap persists. - **LGES Wins Multi-Trillion-Won Honda Prismatic Deal** — [Source]() — Published 2026-07-31 Largest project win this cycle.

Fourteen of the 72 are manufacturing, roughly $7B. - [Apex 1 Hopkinsville — The Divergence Dates to 2024-11-11]() — By [Ronan Adike]() · Published 2026-07-31 · Format: The Stated vs. Observed Audit Kentucky announced $310M and 250 jobs. DOE reimbursed roughly $206M. The plant reached about 60% complete, never produced a saleable component, and after an April 2026 Chapter 11 filing went to its own general contractor against money already owed. - [Four Status Values, Six Transition Modes: A Survival Taxonomy for the Battery Registry]() — By [Ronan Adike]() · Published 2026-07-31 · Format: Failure Taxonomy Every major US battery project tracker runs on four status values. Hand one a liquidation with a half-built shell, an indefinite pause on a finished building, a change of control on a line that never stopped shipping, and a chemistry swap on a running plant. They come back identical, or they come back blank. - [Four Instruments, Four Survival Rules: Public Money Through Three Battery-Plant Transitions]() — By [Elise Huan-Cartwright]() · Published 2026-07-31 · Format: Subsidy and Eligibility Reset USD 3.805 billion of federal loan principal sits advanced against two Kentucky plants, and it is verifiable to the dollar, for the mundane reason that Ford must report its own debt. Who claims the 45X credits at a Tennessee cell plant is not verifiable at all. Four subsidy instruments, four different rules about what survives a bankruptcy, a loan assumption, or a control transfer, and a second variable running independently of all four: whether anyone outside can establish it. Three transitions traced from commitment to disbursement to current status, with the dark parts named as dark. - **Ascend Elements: TKJV Declines WPI Licenses by June 26 Deadline; Apex 1 Site Severed from Process IP** — [Source]() — Published 2026-07-31 Court filings confirm site-IP split.

Clearest clawback precedent to date. ### [Defense]() Drone, UAV, UUV, and 6T battery intelligence - [DIBC's Cylindrical Cell RPP Asks Less Than §4865 Requires]() — By [Ronan Adike]() · Published 2026-07-31 [RPP BES-26-01](https://www.dibconsortium.org/wp-content/uploads/2026/06/P07-DIBC-BES-26-01_Batteries-RPP.pdf), issued by the Defense Industrial Base Consortium on June 22, puts the first public numbers on domestic 18650/21700 production: 50 MWh annually within two years of award, 3 GWh as the objective. Before treating an award as a compliance signal, read the supply-chain terms against the statute. - [The Mandate Gap — 427 Days to a Battery Prohibition With No Rule Behind It]() — By [Ronan Adike]() · Published 2026-07-31 · Format: The Mandate Gap The rulemaking object exists. It is DFARS Case 2024-D011, touching Parts 212, 240 and 252, and it carries a second battery prohibition nobody has been tracking: six named Chinese manufacturers, no chemistry limit, no dollar threshold, binding 92 days ahead of the §4865 cost test. The July 2026 proposed-rule milestone passed with nothing published. Four comparable DFARS source-restriction cases ran a median 312 days from proposal to final rule. DoD also holds an instrument that drops clause text into solicitations without a comment period at all. - [Authority, Not Obligation: The Defense Battery Demand Signal Has No Floor]() — By [Ronan Adike]() · Published 2026-07-31 · Format: Missing Market Signal The Defense Industrial Base Consortium wants 3 GWh of domestic cylindrical-cell capacity stood up inside two years. It also states, in writing, that no offtake is guaranteed. Its threshold cycle life is 300 cycles, which makes the commercial fallback largely notional. - **Battery DFARS Rule Misses Its July Window** — [Source]() — Published 2026-07-31 Case 2024-D011 (RIN 0750-AM08) was slated for a July 2026 NPRM covering both the FY2024 named-manufacturer restriction and Section 4865's cost-origin test. Nothing appeared in the Federal Register through July 31. Without it, contracting officers lack any DFARS procedure for evaluating battery compliance claims. - **DIBC Cell Solicitation Closed, Award Still Pending** — [Source]() — Published 2026-07-31 RPP BES-26-01 closed Phase I submissions July 17 for domestic 18650/21700 cylindrical production (50 MWh threshold, 3 GWh objective). No award through month-end. Phase II hinges on FY2027 appropriations. Worth flagging: the solicitation's 95% electrode-active-material metric diverges from Section 4865's broader functional-component-cost test. - **Packet Digital Holds Strongest Domestic Conversion Position** — [Source]() — Published 2026-07-31 Two Navy orders totaling $36.8M fund pilot production and LRIP-stage pouch-cell manufacturing under SBIR Phase III and APFIT authority, with completion dates running through April 2028. This is the furthest-advanced publicly documented domestic defense cell program. Neither award discloses annual output, Section 4865 cost-origin data, or program-of-record adoption. - **Forge Nano Samsung SDI File SEC Disclosure** — [Source]() — Published 2026-07-31 SEC-filed exhibit confirms a 3 GWh/year cylindrical-cell facility in Morrisville, NC: $300–330M capex, $100M DOE grant, 2028 SOP target. Samsung SDI signed a conditional procurement agreement. No DoD contract, QPL milestone, or Section 4865 proof package accompanies the filing. Editorial assessment: two to three conversion gates from compliant defense supply. - **Blue List Flat at Seventy One UAV Rows** — [Source]() — Published 2026-07-31 DCMA's public endpoint shows 71 UAV records as of July 31, unchanged from July 24, despite DCMA reporting accelerated onboarding on July 27. The public schema still exposes no battery-supplier, cell-origin, or Section 4865 compliance fields. Platform certification and battery-origin compliance remain parallel tracks that do not substitute for each other. - **QPL 32565 Remains Empty: Zero Qualified Products** — [Source]() — Published 2026-07-31 DLA Quick Search confirms no products or sources under MIL-PRF-32565. Stryten Energy independently corroborates: no vendor has demonstrated full compliance. Active SBIR Phase II awards (Tyfast, Farad Power) indicate development work, but development milestones and QPL listing are different gates. Zero listed products means zero compliant production contract pathways. - **Executive Order Tightens Adjacent Waivers, Not Batteries** — [Source]() — Published 2026-07-31 The July 20 EO mandates documented mitigation plans for Section 4872 covered-material waivers starting January 2027. It does not touch Section 4865's battery-specific waiver procedure.

It never puts a value on any of it. The most consequential clause on this card, §10/11.5.6(a), contains exactly one number, and that number is the one-atmosphere applicability trigger. What follows extracts every published requirement in the lane, sorts the missing values into the ones your program owes and the ones nobody has written, and names the largest void: propagation under external hydrostatic pressure. It also corrects Issue #6. - **ABS §10/11.5 Sets Subsea Pack Safety Architecture** — [Source]() — Published 2026-07-31 January 2025 edition (unchanged per 2026 notice) requires third-party certification to UN 38.3, UL 1642, or IEC 62619; marine suitability evidence; housing selection (one-atmosphere or pressure-compensated); and BMS functional requirements per §10/11.5.4. No energy density, cycle life, or C-rate thresholds appear. DVP action: create rows for certification basis, housing type selection, and each BMS function enumerated in §10/11.5.4. - **§10/11.5.6 Requires Pressure Test, Leaves Protocol Open** — [Source]() — Published 2026-07-31 Mandates pressure testing to design depth with satisfactory operation demonstrated, plus Surveyor-witnessed BMS functional testing. Cycle count, hold duration, pressurization rate, and monitoring instrumentation are not prescribed. The program defines these in consultation with ABS at plan approval. DVP action: define and document the pressure test protocol as a program-specific line item, not a standard citation. - **§19/33.3 States the Objective, Not the Number** — [Source]() — Published 2026-07-31 The 2024 rule requires the on-board power source to have adequate capacity for mission duration. Full stop. No Wh floor, no Wh/kg target, no C-rate limit, no DOD ceiling, no derating factor. Energy budget, margin policy, and worst-case assumptions are entirely program-defined. DVP action: build energy adequacy analysis as a program-owned deliverable traceable to this clause. - **§19/37 Acceptance Tests Include Battery Functional Demonstration** — [Source]() — Published 2026-07-31 Five Surveyor-witnessed tests are mandated: piping hydrostatic, insulation resistance, functional testing of all systems, test dive, and sea trials. Battery pressure and BMS functional tests per §10/11.5.6 map to the functional testing and test dive events. Trial procedures remain program-defined. DVP action: link battery test rows to the §19/37 acceptance test sequence and confirm Surveyor witness points. - **IEC 62619 Scopes Industrial Batteries, Including Marine** — [Source]() — Published 2026-07-31 Edition 2.0 (2022-05-24, stability date 2026) covers secondary lithium batteries for industrial applications, marine vehicles included. Contains a battery-system propagation test (Clause 7.3.3) and abuse tests. Clause-level acceptance criteria require the licensed standard text. Does not address subsea pressure envelopes or mission-specific profiles. DVP action: cite for safety and abuse test rows; do not cite for pressure or performance. - **UN 38.3 Governs Transport, Not Operational Suitability** — [Source]() — Published 2026-07-31 Rev 8 Amendment 1 (2025) establishes transport eligibility through type-level abuse tests. ABS §10/11.5.1(c) also accepts it as battery-safety certification evidence. The 20 Wh/cell and 100 Wh/battery values are transport-classification thresholds, not performance specifications. DVP action: maintain separate rows for transport eligibility and ABS certification basis. Do not conflate the two claims. - **ISO 20682 Explicitly Excludes Batteries From AUV Scope** — [Source]() — Published 2026-07-31 Published February 2026, this first-edition AUV risk standard covers sensors, communication, and digital-mission components. Its abstract explicitly excludes batteries and electrical motors. No ISO standard currently governs AUV battery qualification. DVP action: do not cite for any battery row. Included here to prevent misassignment. - **ISO 21173 Governs Pressure Hulls, Not Battery Housings** — [Source]() — Published 2026-07-31 Edition 1 (2019, confirmed 2025) specifies hydrostatic pressure testing for pressure hulls, viewports, hatches, connectors, and buoyancy materials. Battery packs and housings fall outside its scope. Battery housing pressure testing is governed by ABS §10/11.5.6(a). DVP action: do not cite for battery housing rows. Included to prevent a common misassignment. - **A Novel Pressure Compensated Structure of Lithium-Ion Battery Pack for Deep-Sea Autonomous Underwater Vehicle** — [Source]() — Published 2026-07-31 Compares structural weight fractions of rigid-hull and piston-based oil-immersed battery housings across 300–6,000 m (3–60 MPa). Reports ~18.3% system-level mass reduction at 6,000 m for the compensated design. Provides architecture-selection evidence only. No acceptance criteria, no cycling under pressure, no thermal runaway characterization. Tier 3 source. - **Review of Energy Technologies for Unmanned Underwater Vehicles** — [Source]() — Published 2026-07-31 Open-access 2026 review independently corroborates Li et al.'s mass-reduction figures and adds a technology comparison: 140–180 Wh/kg system-level (gravimetric) for oil-filled architectures versus 100–130 Wh/kg for rigid hulls. Identifies 2,000 m as the depth where rigid-hull structural mass begins dominating system weight. Tier 3 peer-reviewed analysis, not standard-set values. - [The Subsea Authority Chain Runs Through Class, Not ISO]() — By [Ronan Adike]() · Published 2026-07-31 If you are populating a UUV pack DVP and looking for the ISO number that anchors it, there isn't one.
