The PowerQ US datasheet prints no energy for any battery stack configuration; the energy depends on the stack and stays unknown.
Not printed: the PowerQ US datasheet gives the AIO-US-EQL2 to EQL7 battery stacks only as dimensions and weights, with no energy for any stack or combination. Nothing is inferred from the datasheet figure or from another Fox ESS battery document.

FOXESS CO., LTD.'s own two-page US datasheet (PDF), linked from the Downloads > Datasheets page of us.fox-ess.com and captured on October 20, 2026. The page 2 table is read from the rendered page: the PDF text layer prints the row labels and the column values in separate runs, so each cited value is quoted as it appears in the text layer and its row was confirmed on the rendered page. It prints no energy for any battery stack. Manufacturer document, not an independent test.

Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
Missing details. This number counts only the evidence recorded so far. The source review for this product is not finished, or the maker has not disclosed enough, so the number can only go up.
Missing for this product: Certificates evidence needed; Warranty energy disclosure evidence needed; Lifetime / capacity evidence needed; Cell model disclosure evidence needed.
AC-coupled · Format not recorded · Usable capacity
The warranty term and the lifetime energy are each scored against the best documented value for a home storage battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
12.5 years · 20% weight
12.5 of 20 years, the best documented for a home storage battery (printed by the maker): Bioenno Power 6V 3Ah LiFePO4 Battery (PVC, BLF-0603W)
Printed as "12.5" in the row "Warranty [Year]"; the datasheet gives no terms.
62.5 / 100 × 20 = 12.5 points.
