    Recommended Applications
    Custom lithium battery packs  •  E-bikes / e-scooters / light EV  •  High-drain cordless power tools  •  Drones, robotics, and automation  •  Motorsport / high-current mobility  •  Energy storage and backup systems (with proper BMS and thermal design)
    Not intended for standalone use in flashlights, e-cigarettes, or any device without a properly designed protection circuit.
    Pack Building Notes
    1. This is a bare industrial cell. Always integrate a BMS matched to series/parallel count, charge voltage (4.20V/cell), and current.
    2. High current requires low-resistance nickel, quality spot welds, adequate busbars, and thermal monitoring. Series resistance dominates losses at 40–60A.
    3. Treat 60A continuous as a thermally limited rating. Use a 75°C surface cut-off (or more conservative limit) and sufficient airflow / heat sinking.
    4. Balance cells before assembling a pack. Do not mix different models, ages, or capacities in the same series string.
    5. Spot-weld only. Direct soldering can overheat the cell and damage internal structure.
    Safety Warnings
    • Unprotected high-energy lithium-ion cell. Misuse can cause fire, burns, or explosion.
    • Always use a BMS. Never short-circuit, overcharge, over-discharge, puncture, crush, or expose to fire / water.
    • Never carry loose cells in a pocket, bag, or with keys / coins. Use an insulating case for storage and shipping.
    • Do not use if the wrapper, insulator, or can is damaged, dented, leaking, or swollen.
    • Charge only with a lithium-ion charger set to 4.20V per cell. Do not leave charging unattended.
    • Keep away from children. For professional pack assembly only.
    • Specifications are manufacturer typical values. Actual capacity and current capability vary with temperature, age, and pack design. This listing is not a substitute for the official datasheet.
