The Sonite case family sized for 21700 cells: the larger cell format packs roughly a third
more energy into the same series/parallel layouts, so a 13S4P case reaches higher capacity
than its 18650 counterpart without changing the frame fit. Variants cover top-pull,
down-pull, straight-tube and flattened-tube removal styles.
These are wholesale, quote-only enclosures (case only — no cells or BMS included). Tell us
your cell count, series/parallel layout and frame mounting style and we’ll confirm the
matching model and pricing.

Highlights
- 21700-native sizing: purpose-cut cell cradles for the high-capacity 21700 format — no adapter spacers.
- Higher energy, same fit: more watt-hours per case than the equivalent 18650 layout.
- Four removal styles: top-pull, down-pull, straight and flattened tube variants.
