Lithium Polymer Battery Cell

Approved IEC CE UL Certificates

Lithium-ion Battery Pack

C9074170HP 3.5V 24Ah

High-Power Output in a Compact Pouch Format

24Ah Nominal Capacity

The cell provides a nominal capacity of 24,000mAh and a minimum capacity of 23,500mAh when measured at a 0.2C discharge rate.

Approximately 84Wh Energy

With a nominal voltage of 3.5V and a capacity of 24Ah, the cell provides approximately 84Wh of nominal energy.

3C Continuous Discharge

The maximum specified continuous discharge current is 72A, allowing the cell to support applications with sustained high-power demand.

5C Burst Discharge

The cell supports up to 120A burst discharge for a maximum of 60 seconds, making it suitable for temporary peak loads such as motor startup, acceleration and actuator operation.

Low Internal Resistance

Initial AC internal resistance is specified at no more than 1.6mΩ when measured at 1kHz and approximately 50% SOC.

Compact Flat Structure

The maximum cell thickness is 9.3mm, helping engineers create relatively thin and space-efficient high-power battery modules.

Rapid Charging Capability

The cell supports a maximum charging current of 0.5C, equivalent to 12A, with a reference rapid charging time of approximately three hours.
