Side-pull battery enclosures release sideways out of the frame — the layout of choice when a rear rack, child seat or frame geometry blocks vertical removal. All three sizes take either 18650 or 21700 cells, and the largest SSE-144 reaches 10S8P (80 cells) for high-capacity touring and cargo packs.

These are wholesale, quote-only enclosures (case only — no cells or BMS included). Tell us your cell format, series/parallel layout and frame clearance and we’ll confirm the matching model and pricing.
