Usable capacity and warranty measurement. The EF BD-5-S2 manual publishes 4.85 kWh usable capacity at beginning of life, with ambient and stabilized battery at 25°C, 0.2C charge/discharge and 100% laboratory test DoD. This is a conditioned battery result; AC-delivered energy, field output and universal operating DoD are not established. The AU/NZ warranty instead calls 5.02 kWh Usable Energy under a separate test protocol. That difference remains unresolved. The AU datasheet listed on 15 September 2026 also prints 5.02 kWh as usable capacity for the same module under a footnote citing 100% DoD, 0.2C and 25°C at beginning of life, so two maker documents disagree and neither explains the difference. The warranty-throughput ratio uses the policy’s own 5.02 kWh basis; the 4.85 kWh laboratory result does not change the warranty entitlement. Source 1.Source 2.

US Support Note
- Current text
- EcoFlow does not publish the OCEAN 2 Plus exact product for the United States. The US OCEAN Pro platform is a different 10 kWh split-phase product and is not treated as a regional variant or source of inherited warranty rights for this record. Re-checked 7 October 2026: the US documentation centre lists OCEAN Pro, gateway, panel, meter backup switch, EV charger, app and PowerInsight products and no OCEAN 2 product; the US warranty page applies to the OCEAN Pro home solar battery solution; the California Energy Commission energy storage list (data unchanged since 1 October 2026) lists EcoFlow EF-OCEANP and EFYJ751 entries and no EF BD-5-S2.

DE Support Note
- Current text
- EcoFlow's current German single-phase page is the smaller OCEAN 2 with two MPPTs, up to 6 kW AC output and six battery modules. This record scores the OCEAN 2 Plus single-phase platform with three MPPTs, up to 12 kW AC output and twelve modules. The EU Plus page does not establish an exact German sale path. Re-checked 7 October 2026: the German documentation centre lists OCEAN 2 single-phase, OCEAN 2 three-phase and OCEAN 2 battery documents and no OCEAN 2 Plus single-phase product, and the German product navigation names no Plus single-phase product. The German single-phase page also lists a 5.02 kWh OCEAN 2 LFP battery with a 15-year warranty statement, shown with the smaller inverter; that statement is not attributed to this record because no German sale path for the Plus platform is established.

Primary datasheetAU Warranty conditions
- Current text
- labour: The battery policy does not state an owner entitlement to site labour, removal or reinstallation; no labour cover is inferred.; registration: Section 1.10 requires the product to remain connected to the internet for critical firmware and safety updates; if disconnected for over one year, coverage adjusts to 5 years from the original activation date. Section 1.3 starts the warranty automatically at the earlier of commissioning or 9 months after the production date and states that no additional manual registration is required.; remedy: EcoFlow may provide online assistance, factory repair, refurbishment or replacement for an accepted claim.; removal reinstallation: No unrestricted removal and reinstallation entitlement is stated.; transferability: The warranty can be transferred from the original owner to the next owner only if the product is still installed in its initial location and has not been moved (V1.4, section 1, introductory paragraph). V1.4 does not state a new-owner registration step.; transport: Materials, accessories and approved logistics for an accepted claim are borne by EcoFlow, subject to the policy process.

AU market evidenceWarranty throughput+8 in JSON recordAU Support Note
- Current text
- The exact single-phase Plus product has a current Australian quote pathway. EcoFlow publishes app, web-portal and PowerInsight management plus a company vulnerability-disclosure route. The exact documents do not state that core battery operation fails without the cloud or provide a dated OCEAN 2 security-support horizon, so neither condition is inferred. Held from AU buyer-ready publication because the exact EF BD-5-S2 identity was absent from the reviewed live CER battery export. EF BD-5-S2 was not located in the live CER battery CSV. Older EF BD-5.1-S1 PowerOcean entries do not establish approval for this new product identity. Re-checked 7 October 2026: EF BD-5-S2 is still absent from the CER battery export of 24 September 2026 and from the CER battery CSV fetched that day, which lists four EcoFlow PowerOcean battery rows (EF BD-5.1-S1, EF BD-10.2-S1, EF BD-15.3-S1 and EF BD-20.4-S1). The integrated inverters EF HD-P1-8K0-S2A, EF HD-P1-9K9-S2A and EF HD-P1-12K0-S2A appear in the CER inverter export of 24 September 2026, approved 8 July 2026 and expiring 8 July 2029; that is an inverter approval and does not establish the battery identity.
