Dear MFS Customer,
Our records indicate that you have purchased one or more Sony VTC 18650-size batteries from MyFreedomSmokes. This letter is to inform you of an important advisory from Sony Electronics, the manufacturer of the VTC4 and VTC5 batteries, regarding the use of these products in vaping devices.
Sony has stated that the VTC battery is not intended for use in any vaping/electronic cigarette device, and that the use of their batteries in such devices presents a danger of fire or explosion.
Sony has not indicated that the VTC batteries are faulty in any way, nor have they issued any recall on VTC batteries, however they have made clear that they are in no way responsible for improper use of their batteries in unapproved devices such as vaping box mods and mechanical mods.
Following our receipt of this letter, MyFreedomSmokes has decided to stop selling Sony VTC4 and VTC5 18650-size batteries. We also wish to inform you, as the owner of one or more VTC batteries, that you are solely responsible for how you choose to use your VTC battery or batteries. As a responsible and well-informed vaper, you should be aware of the risks associated with the use of high-amperage batteries in any application, including vaping. More information on 18650 battery safety is available here: http://onvaping.com/battery-safety-and-ohms-law/
Below is the letter from Sony Electronics in its entirety
