Description
The Power Pack 11.1V 22000mAh 3S11P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable battery solution designed for applications requiring reliable 11.1V power and extended operating time.
This battery pack uses 18650 NMC lithium-ion cells arranged in a 3S11P configuration, providing a nominal voltage of 11.1V and a capacity of 22000mAh (22Ah). With approximately 244.2Wh of energy, it is suitable for portable equipment, robotics, industrial electronics, backup systems and other custom applications.
The pack is equipped with a 3S 20A BMS (Battery Management System) to help protect the battery during charging and discharging.
Battery Configuration
The pack uses a 3S11P configuration:
- 3S = 3 cell groups connected in series
- 11P = 11 cells connected in parallel in each group
- Total cells: 3 × 11 = 33 × 18650 cells
- Cell capacity: 2000mAh
- Pack capacity: 11 × 2000mAh = 22000mAh (22Ah)
- Nominal voltage: 3 × 3.7V = 11.1V
- Maximum charge voltage: 3 × 4.2V = 12.6V
BMS Protection
The integrated 3S 20A BMS helps provide protection against:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell voltage imbalance/protection
- Abnormal battery operating conditions
Important: The 20A BMS rating is the BMS current rating. It should not automatically be interpreted as a guaranteed continuous 20A output rating for the complete battery pack.
Charging
Use a dedicated 12.6V Li-ion/NMC charger for this battery pack.
