Samsung 18650 3000mAh 30Q High Drain Battery

Genuine Samsung high drain flat top lithium battery 18650 30Q 3000mAh. The price is for two batteries.

High drain means the battery cells can handle the higher output amperage (current) required in variable voltage / wattage e-cig mods. To put it another way, these batteries discharge their current at a continuous rate without dropping off when the power begins to run down.

Be sure to only use the correct batteries in your device. All our e-cig mods have suitable batteries listed within their individual categories.
