XTAR VC4 + 4 x Panasonic NCR18650B (flat top) with cases Marsen Energy has combined an XTAR VC4 advanced charger with Panasonic NCR18650B cells with protective safety cases and discounted when bought as a pack


The XTAR VC4 is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The VC4 automatically detects Li-ion, Ni-MH and Ni-Cd batteries. Intelligent charging circuitry selects the optimal charging mode (TC,CC and CV ) for a given battery and each of the VC4s four 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 4 batteries simultaneously
  • Each of the four battery slots monitors and charges independently
  • Compatible with and identifies Li-ion (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440), Ni-MH and Ni-Cd (AA, AAA, AAAA, C) rechargeable batteries
  • 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
  • Maximum of 1000mA charging for faster charge times
  • 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

Panasonic NCR18650B (unprotected, flat top)


The Panasonic B is the most popular 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.

Package includes:

  • 1 x XTAR VC4 Advanced Charger
  • Panasonic NCR18650B 3.6v batteries
  • Battery safety cases
