Fenix USB Rechargeable 18650 Battery

The Fenix USB Rechargeable 18650 li-ion battery (model ARB-L18-3500U) provides the power and functionality of an 18650 li-ion cell, but with the inclusion of a micro-USB port to allow for charging directly into the battery. While still usable in compatible battery chargers (Fenix's ARE-A and D series), the ARB-L18-3500U allows for on-the-go charging from wall sockets or car power receptacles.
