20S13P Battery Configuration

The battery pack consists of 20 series groups, with 13 cells connected in parallel in each group.

20S × 13P = 260 cells

Using 3.7V 4500mAh cells:

• Total cells: 20 × 13 = 260 cells
• Nominal voltage: 20 × 3.6V = 72V
• Maximum charging voltage: 20 × 4.2V = 84V
• Parallel capacity: 13 × 4.5Ah = 58.5Ah
• Nominal energy: 72V × 58.5Ah = 4,212Wh
• Total energy: Approximately 4.21kWh

3C Lithium-Ion Configuration

The cells are specified as 3C-rated cells. The complete battery pack’s safe operating current is determined by the BMS and overall electrical and thermal design, rather than the cell C-rating alone.

The final discharge capability depends on:

• BMS continuous and peak current rating
• Cell specifications
• Nickel/copper interconnection design
• Wire gauge
• Connector rating
• Thermal management
• Operating temperature

 BMS Protection

A suitable 20S NMC BMS can provide:

• Overcharge protection
• Over-discharge protection
• Over-current protection
• Short-circuit protection
• Over-temperature protection
• Cell voltage monitoring
• Cell balancing
• Charging and discharging control

A Smart BMS can also be configured with Bluetooth, CAN, UART or RS485 communication depending on the application.
