ASP 21700 USB-C Battery & Link Case

ASP Lithium-Ion rechargeable batteries are custom-fabricated to provide increased energy density and longer life. Our 21700 battery is optimized for use in high-drain devices such as our performance flashlights, and features a Protection Circuit Module (PCM)—an important safety feature that guards against overcharging or over-discharging.

Our latest generation of Lithium-Ion batteries feature an integrated USB-C charge port. This means that in addition to in-light recharging (with compatible ASP flashlights), the battery can be charged on its own, simply by plugging a USB-C cord directly into the cell. We recommend our Retractable cords (sold separately), or any common, quality USB-C charge cord may be used.

The 21700 includes a Link Case, to safely store, protect and transport the battery. It features an interlocking design that allows multiple Link Cases to be connected to one another for efficient organization.

ALL flashlights and/or batteries cannot go UPS Ground to Alaska, Hawaii, Puerto Rico, US Virgin Islands or Channel Islands off the shores of California.
