Technical Specifications

• Chemistry: Lithium Nickel Manganese Cobalt Oxide (NMC) — offers an optimal balance of high energy density, long cycle life, and excellent thermal stability.

• Configuration: 20S 7P

  • 20S (Series): 20 cells connected in series to achieve a high nominal voltage of 74V (frequently used in higher-power 72V-class electric powertrains for increased top speed and acceleration).

  • 7P (Parallel): 7 cells arranged in parallel to scale up the total capacity to 31.5Ah.

• Total Energy Capacity: Approximately 2,331 Watt-hours (Wh) (or ~$2.33\text{ kWh}$), delivering an extended range over standard 24Ah or 27Ah models.

Key Features & Design

• Application: Specifically designed for heavy-duty or high-performance electric two-wheelers, delivery e-bikes, and applications requiring sustained high-voltage output under load.

• Battery Management System (BMS): Integrated with a robust internal BMS to safeguard against overcharging, over-discharging, over-current, and short circuits, while managing cell-to-cell balancing.

• Efficiency: Features a compact footprint relative to its large energy capacity, ensuring a lightweight and drop-in alternative to bulky traditional lead-acid batteries.
