High-Discharge Performance

The INR2170-50D2 is built for high-current discharge. Its maximum discharge current is 60A, with an 80°C temperature cut-off for safety. The maximum charging current is 15A, enabling fast-charge pack designs when properly managed.

Rate Discharge Test

• Charge: 8A constant current to 4.2V, then 4.2V constant voltage to 100mA cut-off

• Discharge: 10A, 20A, 30A, 40A constant current to 2.5V

Cycle Life

Under 25±2°C:

• Charge: 8A to 4.2V, then 4.2V CV to 100mA

• Discharge: 40A to 2.5V, with 80°C temperature cut

After 600 cycles, capacity remains ≥2,970mAh, which is 60% of the rated capacity. This is a solid cycle-life profile for high-discharge 21700 cells used in power tools, e-mobility, and small energy storage systems.

Temperature Discharge Performance

This temperature tolerance supports use in outdoor power equipment, cold-climate e-bikes, and portable energy storage.
