Power Pack 14.8V 16000mAh 4S8P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack

Description

Power Pack 14.8V 16000mAh 4S8P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack

The Power Pack 14.8V 16000mAh 4S8P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable battery pack designed for portable electronics, robotics, industrial equipment, backup power systems, and custom applications requiring a reliable 14.8V power source.

This battery pack uses 18650 NMC lithium-ion cells arranged in a 4S8P configuration, providing 14.8V nominal voltage and 16000mAh (16Ah) capacity. The integrated 4S 20A BMS helps protect the battery during charging and discharging.

4S8P Configuration

The battery pack uses a 4S8P configuration with a total of 32 cells:

• 4S = 4 cell groups connected in series
• 8P = 8 cells connected in parallel in each group
• Total cells = 4 × 8 = 32 cells
• Cell capacity = 2000mAh
• Parallel group capacity = 2000mAh × 8 = 16000mAh
• Nominal pack voltage = 3.7V × 4 = 14.8V
• Maximum charge voltage = 4.2V × 4 = 16.8V
• Energy capacity = 14.8V × 16Ah = 236.8Wh

The 4S configuration provides the 14.8V nominal voltage, while the 8P configuration increases the capacity to 16Ah.

4S 20A BMS Protection

The battery pack is equipped with a 4S 20A BMS to help protect the battery cells during charging and discharging.

Typical protection functions include:

• Overcharge protection
• Over-discharge protection
• Over-current protection
• Short-circuit protection
• Cell voltage monitoring
• Charging protection
• Discharging protection

The actual continuous current capability depends on the selected cells, BMS design, wiring, connectors and overall pack construction.

Charging

Use a dedicated 16.8V NMC/Li-ion charger for this 4S battery pack.

Charging specifications:

• Nominal battery voltage: 14.8V
