Acebeam 21700 with Built-in USB-C port 

The built-in charging feature of this battery adds additional length to the battery which may make it incompatible with your flashlight. If your flashlight did not come with a battery with built-in internal charging please do not purchase this without verifying compatibly before purchase. We are here to help with concerns and questions about compatibility. Please use the contact us page on the website to get help before you place an order!

***Batteries purchased without any equipment they can operate must be shipped with ground shipping. If you purchase only batteries and no flashlights/headlamps you must select UPS Ground even if other options are available unless your order meets the free shipping threshold.***

** The included Acebeam charging cord or USB-A to USB-C cable is recommended. USB-C to USB-C cables will not work **
