INR18650-2000mAh-15C
Ultra-high-drain 18650 for extreme power applications. 15C continuous, 30A rated.
Product Overview
The INR18650-2000mAh-15C is the highest-drain cell in our curated selection — rated for 15C continuous discharge (30A) with 20C pulse capability. This cell is purpose-built for applications where instantaneous power delivery is everything: professional-grade cordless power tools, high-torque electric actuators, and emergency cranking batteries. Its ultra-low internal resistance (≤12mΩ) minimizes heat generation even at extreme loads.

- High-drain industrial actuators
- Competition-grade RC/drone packs
- Emergency jump starters
Why We Chose This Cell
At 15C, this cell operates in territory where most 18650s fail thermal testing within minutes. In our sustained 30A discharge test (30 minutes at 30A), cell surface temperature plateaued at 74°C — hot but within the 80°C spec. Six competing cells exceeded 85°C and were rejected. If your application demands the highest current per cell in the 18650 format, this is it.
