Evidence score

9/100Missing details40% documented

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; Cell model disclosure evidence needed.

48 V · Server rack · Rated 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.

Warranty term5 years5 / 20

5 years · 20% weight

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 "Warranty 5 years" in the user manual and the datasheet; no terms are printed.
