Molicel 21700 Batteries

Molicel 21700 cells are premium high-drain lithium-ion cells from E-One Moli Energy, a Taiwanese manufacturer that's become a benchmark among serious pack builders.

When builders talk about top-tier high-drain cells, Molicel is usually in the conversation — known for strong, stable current delivery in power tools, e-mobility, and high-performance builds. Stepping up from 18650, its 21700 cells pair that current capability with the extra capacity and energy headroom of the larger format. Being Taiwan-made, they're also a fit where country of origin matters.

For demanding, high-output builds, Molicel is the cell many builders reach for first — predictable performance when you push it hard.
