Lithium-ion Battery Pack
C1187190MP 3.5V 40Ah
High-Capacity Power in a Compact Pouch Format
40Ah Nominal Capacity
The cell provides a nominal capacity of 40,000mAh and a minimum capacity of 39,200mAh when tested at a 0.2C discharge rate.
Approximately 140Wh Nominal Energy
Based on its 3.5V nominal voltage and 40Ah capacity, the cell provides approximately 140Wh of nominal energy.
3C Continuous Discharge
The C1187190MP supports a continuous discharge current of up to 120A, making it suitable for devices with sustained high-power demand.
5C Burst Discharge
A maximum burst discharge current of 200A can be supported for up to 60 seconds under the specified operating conditions.
Low Internal Resistance
The initial AC internal resistance is specified at no more than 1.6mΩ when measured at 1kHz and approximately 50% SOC, helping reduce voltage drop and heat generation during high-current discharge.
Flat and Space-Efficient Structure
The pouch cell has a maximum thickness of 11.2mm, width of 88mm and length of 192mm, allowing engineers to create compact battery modules with a relatively large energy capacity.
Suitable for Customized Battery Systems
The cell can be configured into customized series and parallel battery modules according to the required voltage, capacity, discharge current and installation space.
