INR21700-3000mAh-10C
High-power 21700 cell. 10C continuous with 3000mAh capacity for industrial drive systems.
Product Overview
The INR21700-3000mAh-10C is our highest-power 21700 offering — 10C continuous (30A) with 3000mAh capacity. It combines the current-handling capability of a high-drain 18650 with the thermal mass and energy capacity of the larger 21700 format. For AGV fleets, heavy e-mobility, and industrial drive systems where both runtime and torque are non-negotiable, this cell is our top recommendation.

Why We Chose This Cell
For industrial drive applications, the math is simple: fewer cells = fewer failure points. At 3000mAh/10C, this cell replaces two 18650-2500mAh-10C cells in parallel while delivering better thermal performance (larger surface area for heat dissipation). In a 10S5P configuration, you get 540Wh with 150A continuous — enough to drive a 3kW AGV motor with 10+ minutes of heavy-use runtime. This cell outperformed 7 competitors in our combined capacity-under-load + thermal stability test.
Certifications

FAQ
How does this compare to the 18650-2500mAh-10C?
20% more capacity at the same discharge rate, with better thermal management due to larger cell body. The trade-off is ~50% heavier per cell and ~18% larger diameter. For space-constrained designs, 18650 may still be the right choice.
