Core Performance Advantages

≥400 IEC standard cycles: Assembled from grade‑A WJ‑SC3600P high‑power Sub‑C cells, pass IEC61951‑2‑2017 cycle test for power‑demanding industrial & handheld equipment.
3S series 3.6V finished SC battery pack: Factory spot‑welded three SC‑3600mAh high‑rate cells, stable 3.6V high‑current output for power‑tool replacement projects.
Strict cell sorting: Capacity, internal‑resistance and open‑circuit voltage matched before spot‑welding, minimize voltage drift during heavy‑load continuous discharge.
High‑rate discharge capability: Designed for medium‑high current loads, good performance for pulse‑drain power‑tool applications.
Wide working temperature: Discharge range from‑10℃ up to +55℃, works reliably for indoor equipment and mild outdoor operating conditions.
Flexible OEM options: Custom flying leads, Tamiya/JST/SM/KET connectors, heat‑shrink sleeve wrapping, polarity adjustment and label printing.
