Printed "Usable energy 4.92kWh" and "Support a maximum of 96% DOD under off-grid and back-up application" in the RX-LFP48100 user manual V1.2; the spec sheet prints 4.92kWh with a footnote naming 90% DOD test conditions; captured on September 26, 2026. Revised on 26 September 2026: The flag came from our comparison of the spec sheet's 90% DOD footnote with its usable energy; the current user manual prints the same 4.92kWh with a 96% maximum DOD and no document prints another usable energy.
Printed as "100A" against "Max. discharge current" in the RUiXU RX-LFP48100 / RX-LFP48100-H specification sheet, captured on September 25, 2026; the value follows the cycle life value in the value block, as its label follows "Cycle life" in the label block.

Not printed for this model in the documents on file. Revised on 1 October 2026: RUiXU prints a 51.2 V nominal voltage and a maximum discharge current for this module but no output power figure.
"Max. charge current" printed as 70A. The RUiXU RX-LFP48100 / RX-LFP48100-H specification sheet sets its labels ("Charge voltage", "Float voltage", "Recommended charge current", "Max. charge current", "Recommended discharge current", "Nominal voltage") and values ("56V 54.6V 50A 70A 50A 51.2V") in separate blocks in the same order and prints one parameter column for both models; captured on September 25, 2026.
Printed as "101~119A@5mins | 120~149A@15S" against "Peak discharge current" in the RUiXU RX-LFP48100 / RX-LFP48100-H specification sheet, captured on September 25, 2026; 149 A is the top of the 15-second band, as on the RX-LFP48100-H record.
Not printed for this model in the documents on file. Revised on 1 October 2026: RUiXU prints a maximum charge current for this module but no charge power figure.
"Recommended charge current" printed as 50A. The RUiXU RX-LFP48100 / RX-LFP48100-H specification sheet sets its labels ("Charge voltage", "Float voltage", "Recommended charge current", "Max. charge current", "Recommended discharge current", "Nominal voltage") and values ("56V 54.6V 50A 70A 50A 51.2V") in separate blocks in the same order and prints one parameter column for both models; captured on September 25, 2026.
"Charge voltage" printed as 56V. The RUiXU RX-LFP48100 / RX-LFP48100-H specification sheet sets its labels ("Charge voltage", "Float voltage", "Recommended charge current", "Max. charge current", "Recommended discharge current", "Nominal voltage") and values ("56V 54.6V 50A 70A 50A 51.2V") in separate blocks in the same order and prints one parameter column for both models; captured on September 25, 2026.
Printed "Weight ~46kg (101lb)", an approximate figure, in the RX-LFP48100 user manual V1.2; the spec sheet prints 47kg (103.6lb); captured on September 26, 2026. Revised on 26 September 2026: Owner rule of September 26, 2026: the exact-model manual's value is primary; the spec sheet value is kept beside it. The manual marks its figure as approximate, so no warning is added.

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 for this product: Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.

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.
