Mass96.5±2g. Manufacturer cathode NMCA mapped to the existing NMC family for this private record; portable sector is an example-use classification. Continuous discharge102A; pulse153A limited to30s; current-rating test temperature unspecified. Typical charge10.2A; maximum charge102A (0–100%SOC). ACIR≤2mΩ at1kHz/30%SOC is NOT DCIR: DCIR, cycle life and price remain unknown. Temperature windows are manufacturer AMBIENT limits, not core/surface cutoffs or safe operating guarantees. External clamping30PSI required; tabs, swelling, seals, electrical insulation and clamp design remain unresolved.
