The spec sheet FAQ gives a different parallel limit.
The NEXUS 2 User Manual and the spec sheet table print "Max 15 in parallel(241.5kwh)" and the product page prints 15 in parallel (up to 240kWh), but the spec sheet FAQ says the batteries "can be connected in parallel up to ten times" and that a configuration "never exceeds 15 total batteries".

Evidence score

16/100Missing 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 · Wall / floor · 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 term12 years12 / 20

12 years · 20% weight

12 of 20 years, the best documented for a home storage battery (printed by the maker): Bioenno Power 6V 3Ah LiFePO4 Battery (PVC, BLF-0603W)

BigBattery publishes "12 Years" against "Warranty" on its own product page for F-NXUS2-48161-G1. The term is the headline figure on that page; the governing warranty document's exclusions, registration conditions and remedy were not read here.

60 / 100 × 20 = 12 points.

Cycle rating disclosed · 20% weight

Documented cycle rating earns 20% of this criterion. More evidence is needed to compare lifetime MWh per kWh.
