Availability: In Stock

Marsen Energy has combined an XTAR VC2 advanced charger with 2 Panasonic Protected NCR18650B cells with a protective safety case.



The XTAR VC2 is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The VC2 automatically detects Li-ion, Ni-MH and Ni-Cd batteries. Intelligent charging circuitry selects the optimal charging mode (CC and CV) for a given battery and each of the VC2s two microcomputer-controlled charging slots then monitors and charges the battery independently. Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current, capacity and time while an intelligent automatic power-off function terminates current when charging is complete. Its as simple as insert, detect and charge.


  • Capable of charging 2 batteries simultaneously
  • Each of the two battery slots monitors and charges independently
  • Compatible with and identifies Li-ion (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440).
  • Integrated LCD panel clearly displays charging parameters and progress
  • Intelligent circuitry detects the battery type and status before entering automatic charge mode
  • Automatically detects battery power status and selects the appropriate voltage and charge mode 
  • Displays actual capacity of batteries
  • Compatible with small capacity batteries
  • Automatically stops charging when complete
  • Features over-charge prevention to protect batteries
  • Features temperature monitoring to prevent overheating
  • Made from durable ABS (fire retardant / flame resistant)
  • Features reverse polarity protection
  • Designed for optimal heat dissipation
  • Certified by RoHS, CE, FCC and CEC

The Panasonic B is the most famous out of all 18650 batteries. When first released several years ago it was the highest-capacity 18650 cell mass produced and thus an essential ingredient in the rechargeable revolution and for the adoption of electric vehicles like the Model S (which has been powered by the Panasonic 18650B for some years). It is still the most requested cell for custom packs. A PCB protection circuit built in to this cell makes this cell perfect for low power applications like torches, the PCB prevents over discharge of the cell which can servery shorten the life of the cell.
