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, 13.92 kWh in the scored configuration.13.92 kWh usableScored configuration: CQ7-L2. Published range 13.92–97.44 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
68 / 100#26 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.

Market context
Global evidencechange in the site menu
Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score is anchored to the smallest complete two-module CQ7-L2 stack. A single 6.96 kWh module is not a complete published system. Scored model: CQ7-L2 · checked 2026-08-02. Evidence.
Australian warranty decision
1 product record
Read the Australian warranty as a claim pathway: the headline term is separate from remedy, labour, freight, site work, transfer and registration conditions.

Australian evidence checked 2026-08-10.
Covered5 sources
Australian warranty scope: Australia and New Zealand; FoxESS Australia warranty V2.7 names CQ7-L2 through L14. The period clause and exact throughput tables say ten years, while one performance paragraph says twelve. Ten years is retained conservatively until FoxESS publishes corrected governing terms.
