"This charger will charge a21700 button top protected cell."









The XTAR FC2 is a smart battery charger for 3.6 – 3.7V lithium-ion, and 1.2V NiMH or NiCD batteries. The dual charger bays are designed with today's larger batteries in mind, and is compatible with ultra-wide 26650s, lengthy 21700s with button-top terminals, and over twenty other battery sizes!
The two bays work independently, allowing you to charge various batteries with ease. A switch on the side of the FC2 can be used to manually switch between 2A, 1A, and 0.5A charging currents.
Each bay is topped with four LEDs, which indicate ongoing charging status, as well as the active current after inserting a battery or using the manual toggle.
