Choosing an 18650 battery should not be based only on capacity.

Higher-capacity cells may provide longer runtime, while a power-type cell such as the INR18650-20D is better suited to applications where discharge capability, voltage stability and current output are important.

For motor-driven equipment, electric mobility products and other applications with changing loads, engineers should consider:

● Required continuous discharge current
● Peak discharge current
● Pack voltage and capacity
● Temperature rise
● Internal resistance
● Expected cycle life
● BMS settings
● Cell consistency

If runtime is the priority, a higher-capacity 18650 model may be more appropriate. If higher current output is required, the INR18650-20D can be a better option.

FAQ-INR18650-20D Cylindrical Lithium-ion Battery

What is the capacity of the INR18650-20D?

The INR18650-20D has a nominal capacity of 2000mAh and a nominal voltage of 3.6V.

Is the INR18650-20D a high-discharge 18650 battery?
