Best 21700 Cells for Ebike Battery Packs
The 21700 format is a strong choice for ebike builds that have room for the slightly larger cell. More capacity per cell means fewer cells for the same range, and the larger surface area handles heat better under sustained load. We filtered for cells with at least 3000mAh and 15A continuous discharge.

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