Empty battery enclosures in the popular Sonite downtube style, sized for 18650 cells: pack
assemblers weld their own 10S-13S packs and drop them into an aluminum shell with the charge
port, discharge connector, lock and LED gauge already integrated. Seven variants cover
top-pull, down-pull and straight-tube removal to match different frame layouts.
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.
