Category: Power

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.

IMPORTANT: Separately-packaged batteries (meaning any batteries not shipped packaged with a flashlight) can not be shipped via US Mail, or by air (UPS overnight, 2-Day, etc.). If you order these batteries, please make sure to only select standard UPS Ground shipping.

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.

Customer Reviews (4.8 / 5 · 5 reviews)

Joshua ★★★★★

The USB-C charging on the case is a game-changer for me—I just plug it in overnight and both batteries are topped off by morning without hunting for a dedicated charger. They've held up well in my high-drain flashlight during a week of nightly walks, with noticeably less drop-off than my old cells.

Isabella A. ★★★★★

The higher energy density is immediately noticeable—my high-drain gear lasts noticeably longer between swaps, and the USB-C link case charges them up fast without needing a separate cradle.

Charlotte ★★★★★

The USB-C port on the case is a game-changer—I just plug it in overnight and wake up to a full charge on both cells, no clunky cradle needed. Energy density feels noticeably better than my old 18650s, and they hold up fine under constant heavy draw.
