6S11P Battery Configuration
The battery pack contains 66 DMEGC cells arranged in a 6S11P configuration:
- 6 cells/groups connected in series = 6S
- 11 cells connected in parallel per group = 11P
- Total cells = 6 × 11 = 66 cells
- Capacity = 11 × 4.5Ah = 49.5Ah
- Nominal voltage = 6 × 3.7V = 22.2V
- Maximum charge voltage = 6 × 4.2V = 25.2V
- Nominal energy = 22.2V × 49.5Ah = 1098.9Wh
3C Lithium-Ion Configuration
The theoretical 3C current calculation is:
49.5Ah × 3C = 148.5A
The 148.5A figure is a theoretical cell-based calculation and should not automatically be considered the continuous discharge rating of the finished battery pack. The actual current capability depends on the selected BMS, cells, interconnects, wiring, connectors and thermal design.
BMS Protection
A suitable 6S NMC Lithium-Ion BMS can provide:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Over-temperature protection
- Cell balancing
- Charging and discharging protection
The BMS should be selected according to the application’s required continuous and peak current.
