Description
BAK 10S 36V 75000mAh (75Ah) 10S15P 3C Lithium-Ion Rechargeable Battery Pack
The BAK 10S 36V 75000mAh (75Ah) 10S15P 3C Lithium-Ion Rechargeable Battery Pack is a high-capacity NMC lithium-ion battery pack designed for applications requiring substantial energy storage and high discharge capability.
The pack uses BAK lithium-ion cells arranged in a 10S15P configuration, providing a commercial 36V-class battery with approximately 37V nominal voltage, depending on the specific BAK cell model used.
With 15 cells connected in parallel per series group and a 5000mAh cell capacity, the pack provides 75Ah capacity. At a 3C cell discharge rating, the theoretical cell-based discharge capability is 40A to 100A as per Bms

10S15P Battery Configuration
This battery uses a 10S15P configuration:
- 10 cell groups connected in series
- 15 cells connected in parallel per group
- Cell capacity: 5Ah
- Total cells: 10 × 15 = 150 cells
- Nominal cell voltage: approximately 3.7V
- Pack nominal voltage: 10 × 3.7V = 37V
- Pack capacity: 5Ah × 15 = 75Ah
- Energy: 37V × 75Ah = 2775Wh
3C Discharge Capability
For a 75Ah pack using cells rated at 3C:
75Ah × 3C = 225A theoretical current
This is a theoretical cell-based value. The actual allowable pack current depends on the BAK cell’s exact datasheet rating, BMS, busbars, nickel/copper interconnects, cables, connectors and thermal management.
BMS Protection
A suitable 10S NMC Lithium-Ion BMS can provide protection against:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell imbalance
- Temperature-related conditions when supported
- Cell voltage monitoring
For a high-capacity pack of this size, the BMS should be selected based on the actual continuous and peak load requirements.
Connector & Wire
The connector and cable configuration can be customised according to the application.
Possible options include:
- XT60
- XT90
- High-current DC terminals
- Anderson-style connectors
- Custom power terminals
For high-current applications, cable and connector ratings must be matched to the actual load.
