    🧠 Engineered for Power & Longevity

    The Molicel P45B chemistry is designed for high-performance electric drive systems.
    Each cell can sustain 35 amps continuous discharge, making this battery ideal for e-bikes that demand consistent torque and long-range reliability.

    Connections are made with solid nickel and copper busbars, spot-welded for low resistance and smooth current delivery.
    Our tight internal frame design enhances heat dissipation — reducing thermal buildup and extending pack lifespan.

    The integrated 60A BMS with temperature protection ensures safe operation under continuous heavy load and balances each cell for optimal cycle life.
