    πŸ“± 100 Balance – Active Balance Bluetooth BMS Technology

    Monitor your eBike battery directly from your smartphone with the free 100 Balance app.
    View real-time metrics such as:

    • Voltage

    • Current

    • Temperature

    • State of charge (SOC)

    πŸ’‘ Active balance technology keeps your battery cells evenly balanced β€” even if not charged to 100%. This extends battery life, optimizes performance, and ensures consistent power delivery under heavy load.

    βš™οΈ Ampace JP40 – Advanced Lithium-Ion Technology

     

    The Ampace JP40 21700 cell represents a new frontier in lithium performance.

    Key Advantages:

    • ⚑ Highest performing 21700 cell by discharge rate

    • ❄️ Cold-weather capable – no capacity loss down to -20Β°C (-4Β°F)

    • πŸ”© Tabless design supports 140A peak bursts (5 seconds per cell)

    • πŸ”₯ Outperforms Molicel P42A, P45B, and P50B in energy and thermal control

    • πŸ§ͺ 100-cycle stress test (30A continuous, 5A charge) showed only 2% capacity loss

    This makes the JP40 ideal for CYC Photon, BBSHD Ludicrous, and BAC ASI setups that demand both current and endurance.

     

    🧠 Construction & Safety

    Each 72V pack is precision-built for performance, protection, and longevity:

    • Solid nickel and copper busbars for low resistance

    • Tight internal structure improves heat dissipation

    • BMS temperature protection for thermal stability

    • Each cell and series is tested before assembly

    • Smart balancing for even voltage and optimized runtime

    Every pack is hand-assembled and tested in Bethlehem, PA, using only certified genuine 21700 cells.
