Lithium-ion Polymer Pouch Ce

Lithium-ion Battery Pack

C8574170HP 3.5V 23000mAh

Provides a nominal capacity of 23,000mAh and a minimum capacity of 21,900mAh when tested at a 0.2C discharge rate.

The combination of 3.5V nominal voltage and 23Ah capacity provides approximately 80.5Wh of nominal energy per cell.

Supports a maximum continuous discharge current of 69A, suitable for applications with sustained high-current demand.

Provides up to 115A burst discharge for a maximum of 10 seconds, supporting temporary peak loads such as motor startup and rapid power acceleration.

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

With a maximum thickness of only 8.8mm, the cell can help engineers build thin and compact high-power battery modules.

Supports charging at up to 11.5A, with a reference rapid charging time of approximately three hours.
