Why these values
How each figure on this part was established
Semi-solid NMC, mfr specific energy 330 Wh/kg (Ultra-High-Nickel + coated diaphragm). Listing headlines '10C' continuous which is INFLATED MARKETING for a semi-solid pack of this density (sister 300Wh/kg pack rates 3C cont/5C peak) — recorded c_rating_cont=3 as the realistic value; treat the 10C as unverified. Among the highest energy-density buyable 12S LARGE packs. VERIFIED: source confirms 33000mAh, 44.4V, 4672.34g, 1465.2Wh, 330Wh/kg, AS150U, dims 213x93x120, headline 10C (=330A) — input matches. Wh check 33x44.4=1465.2 OK; 313.6 Wh/kg realized. FILLED max_continuous_current_a=99 (3C x 33Ah) to match the realistic 3C, not the marketing 330A. SEEDED-VOLTAGE NOTE (2026-06-18 audit): nominal_voltage_v and capacity_wh are seeded at the catalog's chemistry-standard nominal (Li-ion 3.6 V/cell, LiHV 3.8 V/cell) per the battery protocol; this semi-solid cell's true manufacturer nominal is higher (see display_name), so the seeded energy is deliberately CONSERVATIVE (understated a few %) and the Wh / Wh-kg figures above reflect the manufacturer's higher nominal, not the seeded field. A semi-solid voltage carve-out is deferred (CATALOG-DATA-AUDIT-2026-06 B-M2).

Company location is the manufacturer’s base, not the country of manufacture. Where a part states no origin, it stays unstated rather than inheriting its maker’s.
NCAGE identifies a company within the NATO Codification System. We record it where we have found it; not recorded means we have not established one, not that the manufacturer lacks one.
