Lishen 21700 Batteries

Lishen 21700 cells come from Tianjin Lishen Battery, one of the larger, longer-running cylindrical cell manufacturers — production-grade cells for serious pack builders.

Lishen is an OEM-scale maker supplying cells across e-mobility and energy storage worldwide, which means its cells carry the consistency of large-scale manufacturing. Stepping up from 18650, the 21700 format brings more capacity and energy headroom, and Lishen's line gives builders a dependable, well-established cell source to build around.

For a pack builder, the appeal is straightforward: a real manufacturer's cell, built to production standards, as a reliable base for high-capacity 21700 packs.
