18650 2500Mah 35A High Drain Battery

18650 2500mAh 35A High-Drain Battery

These high-discharge rated 18650 cells are among the best options available for demanding applications. Commonly used in the drone world, they are a perfect fit for the Fatshark battery case—keeping your goggles powered through multiple flights.

This 18650 IMR battery features Lithium-ion Manganese Oxide (LiMn₂O₄) chemistry, designed for high-discharge current applications. IMR cells utilize a cathode with a three-dimensional spinel structure, allowing for better ion flow, lower internal resistance, faster charging, and strong high-current discharging performance. Though IMR batteries typically offer a lower capacity compared to other lithium-ion types, they are preferred for high-drain devices such as power tools and medical equipment.
