Description
DMEGC 20S 72V 54000mAh (54Ah) 20S12P 3C Lithium-Ion Rechargeable Battery Pack
The DMEGC 20S 72V 54000mAh (54Ah) 20S12P 3C Lithium-Ion Rechargeable Battery Pack is a high-capacity NMC Lithium-Ion battery pack designed for electric vehicles, high-power mobility systems, industrial equipment, robotics, and other demanding applications.
This battery pack uses DMEGC 3.7V 4500mAh lithium-ion cells arranged in a 20S12P configuration, providing 72V nominal voltage, 54Ah capacity, and approximately 3.89kWh nominal energy.
The 3C cell configuration provides high discharge capability, while the final pack current capability depends on the selected BMS, cell characteristics, interconnections, wiring, connectors, and thermal management.

20S12P Battery Configuration
The battery pack consists of 20 series groups, with 12 cells connected in parallel in each group.
20S × 12P = 240 cells
Using 3.7V 4500mAh cells:
- Total cells: 20 × 12 = 240 cells
- Nominal voltage: 20 × 3.6V = 72V
- Maximum charging voltage: 20 × 4.2V = 84V
- Parallel capacity: 12 × 4.5Ah = 54Ah
- Nominal energy: 72V × 54Ah = 3,888Wh
- Total energy: Approximately 3.89kWh
3C Lithium-Ion Configuration
The cells are specified as 3C-rated. The theoretical discharge capability depends on the cell’s specified continuous discharge rating, but the complete battery pack’s safe operating current is determined by the BMS and complete electrical/thermal design, not by the cell C-rating alone.
Important factors include:
- 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 selected with Bluetooth, CAN, UART or RS485 communication according to application requirements.
