VRK

VRK makes rechargeable cells and chargers for box mods. Most people come here for the VRK 3000mAh 18650, which is not available to order online right now. What you can order is the VRK 20700 Battery, a slightly bigger cell for mods built to take it, and VRK's own charger, the VRK X4 LCD Lightning Fast Charger.

Three rules that matter with loose cells. Buy them in matched pairs if your mod takes two, and keep each pair together for its whole life. Replace any cell whose plastic wrap is torn or nicked, because the wrap is what keeps it from shorting. And never carry a loose cell in a pocket with keys or coins; use a battery case.

Charge cells in a dedicated charger rather than through the mod when you can. For other brands of cells, see the 18650 batteries shelf, and for chargers from every brand, the 18650 battery chargers.
