What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Usable capacity
100% of this battery’s nominal capacity is usable, 12 kWh in the scored configuration.12 kWh usableScored configuration: Battery-Box Premium LVS 12.0. Published range 4–24 kWh.
No reserve is withheld at the stated depth of discharge.
At a sourced 100% depth of discharge the usable and nominal figures are the same number, so no separate nominal capacity is stated.
Usable capacity sourceDepth-of-discharge sourceCapacity guarantee: minimum retained at year 10
No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.
Blackout protection
79 / 100#8 of 90 batteriesWhole-home (via hybrid inverter)
The blackout score is a standalone benchmark of outage resilience only - it re-weights sourced specs already scored in this product’s pillars (backup tier, switchover, surge strength, backup power, off-grid recharge) and never affects the overall score. Dots show the full battery fleet; the marker is this product.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The public range shows one-tower configurations. The score is anchored to LVS 12.0; the 256 kWh parallel maximum is supporting context, not the scored configuration. Scored model: Battery-Box Premium LVS 12.0 · checked 2026-08-05. Evidence.

Strong evidence coverage
31 of 31 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
Record revision. Australian LVS datasheet V2.3 dated 2023-11-24, Australian installation manual V1.2 dated 2024-05-29 and residential warranty V1.1 re-audited 2026-08-06. First-market US and DE overlay review 2026-08-30: official regional catalogues recorded; Australian overlays and scores unchanged.
