Description

Power Pack 14.8V 4000mAh (4Ah) 4S2P 1C BMS 6A Lithium-Ion Rechargeable NMC Battery Pack

The Power Pack 14.8V 4000mAh (4Ah) 4S2P 1C Lithium-Ion Rechargeable NMC Battery Pack is a compact and reliable NMC lithium-ion battery pack designed for applications requiring a stable 14.8V nominal power supply.

The pack uses a 4S2P configuration, providing 4000mAh (4Ah) capacity. It is equipped with a 6A BMS to help protect the battery against overcharge, over-discharge, short circuit, and excessive current conditions.

With its compact design and rechargeable lithium-ion technology, this power pack is suitable for electronics, portable equipment, robotics, lighting systems, backup power and other custom applications.

Key Features

  • Battery Chemistry: NMC Lithium-Ion
  • Nominal Voltage: 14.8V
  • Maximum Charging Voltage: 16.8V
  • Capacity: 2000mAh / 2Ah
  • Configuration: 4S2P
  • Cell Count: 4 cells
  • Cell Rating: 2000mAh per cell
  • Cell Discharge Rating: 1C
  • BMS: 4S 6A
  • Rechargeable lithium-ion battery pack
  • Compact and lightweight power solution
  • Suitable for custom electronic and portable applications

3S2P Battery Configuration

The battery consists of 6 NMC lithium-ion cells arranged in a 4S1P configuration.

  • 4S: 4 cell groups connected in series
  • 1P: 2 cells connected in parallel in each group
  • Capacity per parallel group: 2 × 2000mAh = 4000mAh
  • Nominal voltage: 4 × 3.7V = 14.8V
  • Maximum charging voltage: 4 × 4.2V = 16.8V
  • Total energy: 14.8V × 4Ah = 59.2Wh

1C Lithium-Ion Configuration

The individual cells are rated at 1C.

For a 4000mAh (4Ah) pack:

Maximum theoretical current at 1C = 4Ah × 1C = 4A

The 6A BMS rating does not mean the battery can safely deliver 6A continuously. Actual allowable current depends on the cells, BMS design, nickel/copper interconnections, wiring, connectors and thermal conditions.
