18350 Batteries

18350 rechargeable batteries are short-tube lithium-ion cells (about 18 mm wide and 35 mm long) built for compact EDC flashlights where overall length matters. They are 3.7V Li-ion, share the same chemistry family as 18650 cells, and power the kind of "shorty" single-cell hosts that trade runtime for a pocket-friendly form factor.

This collection focuses on high-drain INR 18350 cells suitable for flashlight use. The headline pick is the flat-top Vapcell A11 18350 1100 mAh 10A, sized for compatible Convoy S2+, Emisar D4V2, Manker, and Lumintop short-tube hosts that handle their own charging externally.

Confirm your light's tip-type requirement (most 18350 flashlight hosts want a flat top with no protection circuit) and verify the cell length fits your tube before ordering. Cells ship from the U.S. and arrive faster than overseas vendors, so you can equip a new shorty host or grab a backup without a long wait.
