EVE INR18650-33V Li-ion Cell, 3300mAh, 10A

The EVE INR18650-33V is a versatile Li-ion cell in the 18650 format, offering 3300 mAh capacity and a continuous discharge capability of up to 10 A. It is designed for applications where endurance and efficiency are important, while still supporting moderate current draw.

Compared to the EVE ICR18650-26V (2550 mAh / 7.5 A), it delivers significantly longer runtime. It is also very close to the EVE INR18650-35V (3500 mAh / 10 A), offering a slightly lower capacity but remaining lighter and often more cost-effective.

With low internal resistance (~20–25 mΩ), the cell maintains stable voltage output under load, making it suitable for UAV battery packs, portable electronics, and industrial energy systems where current demands are moderate.
