  "summary": "3,840 Wh LiFePO4 expansion battery for the Anker SOLIX F3800 (and F3800 Plus), 33 kg. Adds capacity to the host, with no outlets of its own and no direct charging. Up to six chain per host. 5-year warranty. Anker's own page conflicts on hosts, so the compatibility here is the rendered F3800 / F3800 Plus claim with the 'Only F3800' string preserved in notes.",
  "description": "The Anker SOLIX BP3800 is a 3,840 Wh LiFePO4 expansion battery (75 Ah at 51.2 V nominal) in a 33 kg case, built to enlarge Anker's SOLIX F3800 power station. It has no outlets of its own and charges only through the host; up to six units chain per host. Anker's own materials conflict on which hosts it fits: the rendered FAQ and the page's JSON-LD say F3800 and F3800 Plus, another block on the same page says Only F3800, and the user guide names no host at all. This record follows the rendered claim, corroborated by the official F3800 Plus bundle SKU, and lists both the F3800 and F3800 Plus, while preserving the conflicting Only F3800 string in the record notes. The BP3800's own specifications come from its user guide, not from the F3800 station compare-table on the same page, which has no BP3800 column and describes the station. Warranty is 5 years. Cycle life is not published as a depth-of-discharge rating for this unit.",

This record follows the rendered claim (F3800 and F3800 Plus), corroborated by the official F3800 Plus bundle SKU, and the conflicting 'Only F3800' string is preserved here rather than silently dropped. CAPACITY-BLUR TRAP avoided: the page's compare-table is an F3800 station table with no BP3800 column, so its 3,840 Wh, cycle and temperature rows describe the STATION; every BP3800 value stored here (75 Ah, 51.2 V, 33 kg, dimensions, temps) came from the BP3800's own user guide. FILENAME NOTE: the hero uses the station prefix A1790111 (the expansion battery is the -85 SKU), so the filename is not identity; the image itself was opened and confirmed to be the single BP3800 unit. cycleLifeCycles is null: no DoD-qualified cycle rating is published for the unit itself.",
