Description
BAK 4S 14.8V 30000mAh (30Ah) 4S6P 3C Lithium-Ion Rechargeable Battery Pack
The BAK 4S 14.8V 30000mAh (30Ah) 4S6P 3C Lithium-Ion Rechargeable Battery Pack is a high-capacity NMC Lithium-Ion battery pack designed for applications requiring reliable 14.8V power and extended operating time.
This battery pack uses BAK 3.7V 5000mAh lithium-ion cells arranged in a 4S6P configuration, providing 14.8V nominal voltage, 30Ah capacity, and approximately 444Wh energy.
With a 3C configuration, the theoretical discharge capability is 90A. Actual continuous discharge capability depends on the selected cells, BMS, wiring, connectors, interconnections and thermal management.

4S6P Battery Configuration
The pack contains 24 cells arranged as:
- 4 cells in series (4S) → 14.8V nominal
- 6 cells in parallel (6P) → 30Ah capacity
- Total cells: 4 × 6 = 24 cells
- Nominal energy: 14.8V × 30Ah = 444Wh
- Maximum charging voltage: 4.2V × 4 = 16.8V
3C Lithium-Ion Configuration
The theoretical 3C discharge current is:
30Ah × 3C = 90A
The actual usable continuous current should be determined by the complete battery design, including the BMS rating, cell specifications, wiring, connectors, interconnections and thermal conditions.
BMS Protection
A suitable BMS can provide protection against:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell imbalance
- Excessive temperature
- Abnormal charging and discharging conditions
The BMS current rating should be selected according to the actual load requirements of the application.
