We've taken all of our experience, and put it into one product - just for you. Coupled with Fogstar's buying power, we've also priced these as competitively as possible.

There is no Fogstar Branding on Pre-Packaged items.


  • Clear SINGLE 18650 Case - We feel that a case should be provided with all cells as standard - so with our Pre-Packaged cells they are. These cases are premium quality - to ensure cells remain safe.
  • Internal Warning Card - We have included an internal warning code with only one message - in our experience this is the single most important information the customer needs to know to protect you, and themselves and that is not to put these cells in their pocket. Other warnings are displayed on the outer box (below)
  • Premium Printed Matte Laminated Box - Our boxes are not just for show, they provide retail shops, customers and trading standards with important information such as warnings, markings, and battery specifications. There is also a message that the battery has been batch authenticated, to let customers know you are doing your part to fight to the fakes. We have also now added unique barcodes to these boxes.
