As per the UN international shipping regulations for Lithium batteries, they have a (peel off) label with the nominal capacity, nominal voltage and size.

These are high capacity and high discharge current batteries. If mishandled / mistreated, they can cause you SERIOUS INJURY. USE AT YOUR OWN RISK !


Please be sure to inspect your battery before use to ensure it is not damaged including tears/rips in the battery wrap. Discontinue use immediately if battery is damaged.

NOTE: Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended.

We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries and chargers. We only recommend using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc, use of lithium ion batteries without a protection circuit is potentially hazardous.

VapeKing will not be held responsible or liable for any injury, damage, or defect, permanent or temporary that may be caused by the improper use of a LI-ION battery. Please have a basic understanding of the batteries you are using and how to care for them properly.

    These batteries are fine in the Vaporesso Gen S, of course I wish they lasted all day, but we're not quite there yet with technology... other than that they're great.
