Recorded conflicts

max_continuous_charge_current_a / max_continuous_discharge_current_a Review required
52.5 A (0.5C standard); up to 105 A (1C max) — existing ANMA record, derived from the brochure's '0.5C' / '1C' wording
50 A standard; 100 A / 100 Adc BMS maximum — WECO 5K3-XP manual V2.04 p.47 (fetched 2026-09-02)
The existing values were computed from the brochure's C-rate wording against the 105 Ah usable capacity; the manual prints round 50 A / 100 A figures instead. Prefer the manual's explicit amps.
physical dimensions Review required
580 x 474 x 170 mm (axis order not labelled) — manual V2.04 p.30 and p.54
D 492 x H 580 x W 170 mm — brochure 2.1a
The two documents disagree on the third dimension (474 vs 492 mm) and the brochure's axis labelling (D x H x W) cannot be reconciled with the manual's unlabelled triple. Left UNKNOWN rather than guessing which axis is which.
voltage_range_v Review required
46,5 ~ 56.8 Vdc — WECO 5K3-XP brochure EN rev 2.1a (fetched 2026-09-02) - the record's existing value

45.5 Vdc - 58.4 Vdc — WECO 5K3-XP manual V2.04 p.47, 'Extreme voltage range BMS safety min max values'
Three different quantities under one label: brochure 2.1a publishes an operating window, the product page publishes an upper limit of 58.4 V, and the manual publishes the BMS safety extremes (45.5-58.4 V). Existing 46.5-56.8 retained; the 58.4 V ceiling is the BMS protection threshold.
