This is the new format that Nitecore are making for their latest generation of torches.  Its format is 21700 and it’s different from the 18650 – its larger for a start.  Higher capacity and output.  You can only use these in torches that specify 21700i format batteries.  Please make sure your torch is compatible, and if you’re not sure – just ask us.

To charge these, either your torch already has that feature or you will need a UMS2 or UMS4
