Highest Discharge 21700 Cells
The 21700 format is increasingly common in high-drain builds because of its better surface area for heat dissipation. If your application demands sustained current and you have room for the larger format, these 21700 cells lead the field on discharge. Check both the rated and Mooch columns.

Rated A is the manufacturer's continuous figure; Mooch A is independently measured and usually lower. Where they disagree, size to Mooch.
